    50 \subsection{What is a \vym map?}
    51 A \vym map (in short words {\em map}) is a tree like structure:
    52 \begin{center}
    53 	\includegraphics[width=12cm]{example1.png}
    54 \end{center}
    55 Such maps can be drawn by hand on a paper or flip chart and help to
    56 structure your thoughts. While a tree like structure like above can be
    57 drawn manually \vym offers much more features to work with such maps.
    58 \vym is not another drawing software, but a tool to store and modify
    59 information in an intuitive way. For example you can reorder parts of
    60 the map by pressing a key or add various information like a complete
    61 email by a simple mouse click.
    62 
    63 Once you have finished collecting and organizing your ideas, you can
    64 easily generate for example a presentation in Open~Office based on a
    65 map.
    66 
    67 \subsection{Why should I use maps? Time, Space and your Brain.}
    68 \subsubsection*{Space}
    69 A map can concentrate a very complex content on little space e.g. a
    70 piece of paper. It helps to use both sides of your brain: the logical
    71 side and also your creative side (e.g. by using pictures, colors and
    72 keywords in a map, so called {\em anchors}).  It is a technique to
    73 organize the way you think: It can help you by developing, sorting and
    74 memorizing your thoughts. 
    75 
    76 \subsubsection*{Time}
    77 Because you just use keywords and drawings, it is much faster than good
    78 old fashioned notes. Your brain memorizes things by associating them to
    79 other things -- a map makes use of those connections and stimulates
    80 new asccociations. 
    81 
    82 
    83 \subsubsection*{Your Brain}
    84 In 1960 the Prof. {\sc Roger Sperry} discovered that both hemispheres
    85 of the human brain have different tasks (of course both of them
    86 basically {\em can} do the same): 
    87 \begin{center}
    88 \begin{tabular}{|p{5.5cm}|p{5.5cm}|} \hline
    89 	Left side & Right side \\ \hline
    90 	\begin{itemize}
    91 	   \item verbal speech and writing 
    92 	   \item numbers
    93 	   \item logical thinking
    94 	   \item analyzing and details
    95 	   \item science
    96 	   \item linear thinking
    97 	   \item concept of time
    98 	\end{itemize} &
    99 	\begin{itemize}
   100 		\item body language
   101 		\item visual thinking, day dreams
   102 		\item intuition and emotion
   103 		\item overview of things
   104 		\item creativity
   105 		\item art, music, dancing
   106 		\item non-linear thinking, connecting things
   107 		\item spatial awareness
   108 	\end{itemize}     \\ \hline
   109 \end{tabular}	
   110 \end{center}
   111 In our science oriented society we have learned to mainly rely on our
   112 left side of the brain, the "rational" one. In other cultures,
   113 especially like the native americans and other "old" cultures, the right
   114 side is much more important. Maps are just one way to stimulate the
   115 other side and make use of additional ressources we all have.
   116 
   117 
   118 \subsection{Where could I use a map?}
   119 Here are some examples, how you can use those maps
   120 \begin{itemize}
   121     \item to prepare articles, papers, books, talks, \ldots
   122     \item to sort complex data
   123     \item to memorize facts, persons, vocabulary, \ldots
   124     \item to sort emails, files and bookmarks on your computer
   125     \item to moderate conferences
   126 \end{itemize}
   127 
   128 \subsection{What you shouldn't do with a map...}
   129 A map drawn by somebody shows the way the author thinks. There is
   130 no right or wrong in the way it is drawn, so there is no way to criticize
   131 it. "It is, what it is" ({\sc F.~Lehmann}).

   134 %TODO
   135 
   136 \subsection{Internet Ressources} 
   137 A good starting point to learn more about maps in general is Wikipedia:
   138 \begin{itemize}
   139 	\item English: 
   140 		\href{http://en.wikipedia.org/wiki/Mind_map}{http://en.wikipedia.org/wiki/Mind\_map}
   141 	\item German: 
   142 		\href{http://de.wikipedia.org/wiki/Mindmap}{http://de.wikipedia.org/wiki/Mindmap}
   143 \end{itemize}
   144 
   145 
   146 
   147 
   148 \section{Concept of \vym}
   149 %TODO may add a general introduction here...
   150 \subsection{Windows: mapeditor and noteeditor}
   151 \vym uses two windows: an editor for the map itself and another one for
   152 notes, which are part of the map. Let's call them {\em mapeditor} and
   153 {\em noteeditor}: 
   154 \begin{center}
   155 	\includegraphics[width=8cm]{windows.png}
   156 \end{center}
   157 Usually you will work in the {\em mapeditor} by just adding new
   158 branches, moving around and reordering them. The various ways to do this
   159 will be explained in \ref{mapeditor}. You can store additional
   160 information e.g. the content of a email easily in a {\em branch}: Just
   161 type or copy\&paste it into the {\em noteeditor}. Working with notes is
   162 explained in \ref{noteeditor}
   163 
   164 \subsection{Menus and Context menus}
   165 On top of each window you find the menubar. The options you find there
   166 are similar to those you are used from other applications. Note that
   167 many (and even more) options are availabe via {\em context menus}. Those
   168 are available if you right-click onto an object in a map (on Mac~OS~X
   169 Command-Click).
   170 
   171 \subsection{Toolbars}
   172 The toolbars in the mainwindows give quick access to many functions and
   173 also visualize the state of an object. For example a part of of the map
   174 can be hidden when the map is exported into an Open~Office presentation.
   175 To show this the branch in the map will have a little cloud symbol,
   176 which is also "switched on" in the toolbar.
   177 
   178 Note that you can reposition all toolbars by simply grabbing them. For
   179 example you can move the flags-toolbar from its original horizontal
   180 position on top of the mapeditor to a vertical position on the right
   181 side. You can even detach it and make it "float" separate from the other
   182 windows. Or just insert it again at its original position.
   183 
   184 \subsection{Maps}
   185 The map itself has always a {\em mapcenter}.  The
   186 mapcenter has {\em branches} just like the trunk of a tree. Each branch
   187 in turn may have branches again.
   188 \begin{center}
   189 	\includegraphics[width=10cm]{branches.png}
   190 \end{center}
   191 We will call a branch directly connected to the mapcenter a {\em
   192 mainbranch}, because it determines the position of all its child
   193 branches.
   194 
   195 The mapcenter and the branches all have a {\em heading}. This is the
   196 text you see in the mapeditor. Usually it should just be one or a few
   197 words, so that one can easily keep track of the whole map.
   198 
   199 
   200 In the toolbar above the mapeditor you see various symbols.
   201 \begin{center}
   202 	\includegraphics[width=8cm]{default-flags.png}
   203 \end{center}
   204 These are called {\em flags} and can be used to mark branches in the
   205 map, e.g. if something is important or questionable. 
   206 There are also more flags set by \vym automatically to show additional
   207 information, e.g. when a  exists for a  particular branch.
   208 
   209 By default some of these flags are set exclusively e.g. when the 
   210 "thumb-up" flag is set, then the "thumb down" is unset and vice
   211 versa. You can change this default behaviour in the settings menu.
   212 
   213 %TODO add info about toolbars e.g. undo/redo, ...
   214 
   215 \section{Mapeditor} \label {mapeditor}
   216 \subsection{Start a new map}
   217 After \vym is started two windows will open: the mapeditor and the
   218 noteditor. Usually you will work in both windows, but at the moment we
   219 will just need the mapeditor. 
   220 
   221 Select the mapcenter "New map" in the middle of the mapeditor by
   222 left-clicking with the mouse. It will turn yellow to show that is
   223 selected. There are several ways to add a new branch to the center:
   224 \begin{itemize}
   225 	\item In the toolbar click on this icon
   226 		\includegraphics [width=0.5cm]{newbranch.png}
   227 	\item Using the context menu by clicking with the
   228 	right mouse button (CTRL-Click on Mac) onto the
   229 	mapcenter and choose Add \ra Add as child
   230 	\item Press \key{Ins} or \key{A}
   231 \end{itemize}
   232 A new branch will appear and you will be able to type the heading of the
   233 branch. Finish adding the new branch by pressing \key{Enter}.
   234 %tipp
   235 Sometimes it comes handy to add a new branch above or below the current
   236 one. Use \key{Ins} together with \key{Shift} or \key{Ctrl}. It is also
   237 possible to add a branch in such a way, that the current selection
   238 becomes the child of the new branch, which is like inserting it {\em
   239 before} the selection. This can be done using the context menu.
   240 
   241 \subsection{Navigate through a map}
   242 \subsubsection*{Select branches}
   243 To select branches you can use the left button of your mouse or also the
   244 arrow keys. Depending on the {\em orientation} of a branch type
   245 \key{\la} or \key{\ra} to get nearer to the mapcenter or deeper
   246 down into the branches. Within a set of branches, let's call them a 
   247 {\em subtree}, you can use \key{\ua} and \key{\da} to go up and down. You can
   248 also use \key{Pos1} and \key{End} to select the first and last branch.
   249 
   250 
   251 \subsubsection*{Zoom a map}
   252 While adding more and more branches the size of the map may become
   253 bigger than the mapeditor window. You can use the scrollbars on the
   254 right and the bottom of your mapeditor window to scroll, but it is
   255 easier to just scroll using the left mouse button: Click onto the {\em
   256 canvas} itself, the empty space somewhere between the branches. The
   257 mouse pointer will change from an arrow to a hand, now move the visible
   258 part of the map to show the desired part.
   259 
   260 If you select branches using the arrow keys, the map will scroll
   261 to ensure that the selected branch is always visible.
   262 
   263 Working with huge maps, the {\em zoom}-function comes in handy: You can
   264 use 
   265 \begin{itemize}
   266 	\item from the menu View \ra Zoom
   267 	\item the toolbar buttons 
   268 		\begin{center}
   269 			\includegraphics[width=3cm]{zoom-buttons.png}
   270 		\end{center}	
   271 \end{itemize}	
   272 The crossed magnifying lens resets the zoomed view to its original size.
   273 
   274 
   275 \subsubsection*{Find Function} \label{findwindow}
   276 With huge maps there is the need to have a
   277 find function. Choose Edit \ra Find to open the Find Window:
   278 \begin{center}
   279 	\includegraphics[width=6cm]{find-window.png}
   280 \end{center}	
   281 The text you enter here will be searched in all the headings and also in
   282 notes. Everytime you press the "Find"-button it will look for the next
   283 occurence, which then will be selected automatically. If the search
   284 fails, there will appear a short message "Nothing found" or a few
   285 seconds in the {\em statusbar} on the bottom of the mapeditor.
   286 
   287 \subsubsection*{Keep the overview -- scroll a part of the map}
   288 A very big subtree of a map e.g. a branch with hundreds of childs makes
   289 it very hard to keep an overview over the whole map. You can hide all
   290 the childs of a branch by {\em scrolling} it -- this function is also
   291 often called {\em folding}. Think of the whole subtree as painted onto a
   292 big newspaper. You can scroll the paper to a small roll, leaving just
   293 the headline readable.
   294 
   295 To scroll or unscroll a branch and its childs, press the
   296 \begin{itemize}
   297 	\item \key{Scroll} key or  \key{S}
   298 	\item press the middle-mouse button or
   299 	\item choose the little scroll from the toolbar.
   300 \end{itemize}
   301 If you select parts of a scrolled branch e.g. using the find function or
   302 by using the arrow-keys, it will unscroll temporary. This is shown as a
   303 scroll with a little hour glass. If the temporary unscrolled part is not
   304 longer needed, it will be hidden again automatically. It is also
   305 possible to unscroll all branches using "Edit\ra Unscroll all scrolled
   306 branches".
   307 
   308 You can also hide parts of the map while exporting it e.g. to a webpage
   309 or a presentation, see \ref{hideexport} for details.
   310 
   311 \subsection{Modify and move branches}
   312 \subsubsection*{Modify the heading}
   313 You can edit the heading by selecting the branch and then
   314 \begin{itemize}
   315 	\item pressing \key{Enter}
   316 	\item double-clicking with left mouse.
   317 \end{itemize}
   318 Just type the new heading (or edit the old one) and press \key{Enter}.
   319 
   320 \subsubsection*{Move a branch}
   321 The easiest way to move a branch is to select it with left-mouse and
   322 drag it to the destination while keeping the mouse button pressed.
   323 Depending on the branch  it will be
   324 \begin{itemize}
   325 	\item moved to the destination or
   326 	\item {\em linked} to a new {\em parent} (mapcenter or branch)
   327 \end{itemize}
   328 If you drag the branch over another one or over the mapcenter, you will
   329 notice that the  link connecting it to the old parent will be changed to
   330 lead to the  new parent which is now under your mousepointer. 
   331 If you release the button now, the branch will be relinked.
   332 
   333 If you release the button in the middle of nowhere, the result will
   334 depend on the type of branch you are releasing:
   335 \begin{itemize}
   336 	\item A mainbranch is directly connected to the mapcenter.
   337 		It will stay on its new position.
   338 	\item An ordinary branch will "jump" back to its original position.	
   339 \end{itemize}
   340 Thus you can easily rearrange the layout of the mainbranches to avoid
   341 overlapping of their subtrees.
   342 There is another convenient way to move branches, especially if you want
   343 to {\em reorder} a subtree: You can move a branch up or down in a
   344 subtree by
   345 \begin{itemize}
   346 	\item pressing \key{\ua} and \key {\da}
   347 	\item selecting Edit \ra Move branch
   348 	\item clicking on the toolbar buttons:
   349 		\begin{center}
   350 			\includegraphics[width=1.5cm]{move-buttons.png}
   351 		\end{center}	
   352 \end{itemize}
   353 %tipp
   354 There is yet another way to move branches: If you press \key{Shift} or
   355 \key{Ctrl} while moving with the mouse, the branch will be added above
   356 or below the one the mouse pointer is over. This helps also to reorder a
   357 map.
   358 
   359 \subsection{The right side of your brain - colors and images}
   360 \subsubsection*{Change color of a heading}
   361 You can also use colors to put more information into a map, e.g. use
   362 red, green and more colors to prioritize tasks. Again you can
   363 \begin{itemize}
   364 	\item use the menu and choose e.g Format \rq Set Color
   365 	\item use the toolbar
   366 		\begin{center}
   367 			\includegraphics[width=3cm]{color-buttons.png}
   368 		\end{center}	
   369 \end{itemize}
   370 The first button (black in the graphic above) shows the actual color.
   371 Clicking on it let's you choose another color. You can also "pick"
   372 another color by selecting a branch with the desired color and using the
   373 "pick color" button. Both of the buttons showing a bucket actually put
   374 the current color to the selected branch. While the first one just
   375 colors the heading of the selection, the last one also colors all the
   376 childs of the selected branch.
   377 
   378 %tipp
   379 A very useful function is the "copy color" using the mouse: Select the
   380 branch which should get the new color, then press \key{Ctrl} and
   381 simultanously click with left-mouse on another branch to copy its color
   382 to the first one. Here the childs of the selection also will get the new
   383 color, if you just want to color the selection itself, additionally
   384 press \key{Shift}.
   385 
   386 \subsubsection*{Use flags}
   387 \vym provides various flags. You see them in the toolbar on top of the
   388 mapeditor window. (Note: Like all toolbars you can also move them to the
   389 left or the right side of the window or even detach them. Just grab the
   390 very left "dotted" part of the toolbar with your left-mouse button.) 
   391 \begin{center}
   392 	\includegraphics[width=8cm]{default-flags.png}
   393 \end{center}
   394 If you have a branch selected, you can set any number of flags by
   395 clicking them in the toolbar. The toolbar buttons change their state and
   396 always reflect the flags set in the selected branch.
   397 
   398 Presently \vym uses two kinds of flags: {\em System Flags} and {\em
   399 Standard Flags}. The standard flags are those shown in the toolbar.
   400 System flags are set by \vym to indicate e.g. that there is additional
   401 information in a note (more on this in \ref{noteeditor}). Later versions
   402 of \vym may have another kind of flags, which may be edited by the user.
   403 
   404 \subsubsection*{Images}
   405 The easiest way to add an image to a branch is by dragging it e.g. from a
   406 webbrowser to the mapeditor while a branch is selected there.
   407 
   408 You can also add a image to a branch by opening the context menu of the
   409 branch choose "Add Image". A
   410 dialog window lets you choose the image to load. 
   411 \footnote{Supported image types are: PNG, BMP, XBM, XPM and PNM. It may
   412 	also support JPEG, MNG and GIF, if specially configured during
   413 	compilation (as done when \vym is part of SUSE LINUX).}
   414 While an image is selected in the dialog, you can see a preview of the
   415 image. It is also possible to select multiple images.	
   416 
   417 You can position the image anywhere you want, just drag it with left
   418 mouse. To relink it to another branch, press \key{Shift} while moving
   419 it. To delete it, press \key{Del}. 
   420 
   421 If you right-click onto an image, a context menu will open which let's
   422 you first choose one of several image formats. Then a file dialog opens
   423 to save the image. Hint: This is used to "export" the image, it will be
   424 saved anyway in the map itself! You can also cut and
   425 copy images, but it is not possible to add objects to an image\footnote{
   426 	Images are regarded as "extra feature". It would make working with
   427 	the map much more complex if e.g. images could be linked to images.}
   428 
   429 The option \lq{\bf Use for export} \rq controls the output of exports
   430 e.g. to HTML: If set to no, the image won't appear in the {\em text}
   431 part of the output. This is useful for large images or if images are
   432 used as a kind of frame e.g. the famous cloud symbol around a part of
   433 the map. Those shouldn't appear in the middle of the text.
   434 
   435 At the moment image support is preliminary: Images will be saved
   436 together with all the other data of a map in the {\tt .vym}-file.
   437 Later versions will include more functionality like resizing the images,
   438 changing its z-value (put it into background) etc.
   439 
   440 \subsubsection*{Frames}
   441 A frame can be added to a branch by clicking with the
   442 right-mouse button.  A context menu will open, where you can choose the
   443 frame. At the moment just a rectangle resp. "No Frame" will be offered,
   444 nevertheless you can use images as frames. Have a look at the demo map
   445 {\tt todo.vym} as an example, where the mapcenter is a cloud. You can
   446 use an external drawing program like {\tt gimp} to create an image,
   447 preferable with an transparency channel, so that you can design frames
   448 which don't use a rectangular borderline, just like the cloud.
   449 
   450 
   451 \subsection{Background design}
   452 The design of the background of a map and also of the links connecting
   453 various parts of the map can be changed by
   454 \begin{itemize}
   455 	\item Selecting Format from the menu
   456 	\item Right clicking onto the canvas, which will open a context menu
   457 \end{itemize}
   458 
   459 \subsubsection*{Background color}
   460 The color is set (and also displayed) as "Set background color".
   461 
   462 \subsubsection*{Link color}
   463 Links connecting branches can be colored in one of the following ways:
   464 \begin{itemize}
   465 	\item use the color of the heading of the branch the links is
   466 	\item use {\em one} color for all links. The default color is blue.
   467 	leading to.
   468 \end{itemize}
   469 The latter can be set with "Set link color". Check or uncheck the "Use
   470 color of heading for link" option to choose one of the two designs for
   471 your map.
   472 
   473 \subsubsection*{Link style}
   474 \vym offers four different styles for the appearences of links:
   475 \begin{itemize}
   476 	\item Line
   477 	\item Parabel
   478 	\item Thick Line
   479 	\item Thick Parabel
   480 \end{itemize}
   481 The "thick" styles only draw links starting at mapcenter thick, the rest
   482 of the map is always painted "thin".
   483 
   484 
   485 \subsection{Links to other documents and webpages}
   486 \vym supports two kind of external links:
   487 \begin{itemize}
   488 	\item Document, which will be opened in an external webbrowser
   489 	\item \vym map, which will be opened in \vym itself
   490 \end{itemize}
   491 In addition to the external links there also internal ones, leading from one
   492 branch in a map toanother one. Those are called {\em XLinks} and are explained
   493 in section~\ref{xlinks}.
   494 
   495 \subsubsection*{Webbrowser}
   496 Modern Webbrowsers like {\tt konqueror} are able to display various
   497 types of files, both local or in the internet. To enter the URL of
   498 any document, right-click  onto a branch or use the Edit Menu
   499 and choose "Edit URL". Enter the path to your document (or copy and
   500 paste it from your browser). Examples for valid paths are:
   501 \begin{verbatim}
   502 	http://www.insilmaril.de/vym/index.html
   503 	file:/usr/share/doc/packages/vym/doc/vym.pdf
   504 \end{verbatim}
   505 If an URL was entered, a little globe will appear in the branch. By
   506 clicking on the globe in the toolbar or the context menu an external
   507 browser\footnote{
   508 	The browser can be changed in the Settings Menu.}
   509 will be started.
   510 \begin{center}
   511 	\includegraphics[width=0.5cm]{flag-url.png}
   512 \end{center}
   513 For more information on working with bookmarks and webbrowsers see
   514 section \ref{bookmarks}.
   515 
   516 
   517 \subsubsection*{\vym map}
   518 To link to to another map right click on a branch or choose "Edit \ra
   519 Enter \vym link". A file dialog opens where you can choose the map. A
   520 branch with a link is marked with 
   521 \begin{center}
   522 	\includegraphics[width=0.5cm]{flag-vymlink.png}
   523 \end{center}
   524 Clicking this flag in the toolbar or in the context menu of a branch
   525 will open the map in another tab (see \ref{tabs} for working with
   526 multiple maps). To delete an existing link, just press the "Cancel"
   527 button.
   528 
   529 Technical note: Internally \vym uses absolute paths, to avoid opening
   530 several tabs containing the same map. When a map is saved, this path is
   531 converted to a relative one (e.g. {\tt /home/user/vym.map} might become
   532 {\tt ./vym.map}. This makes it fairly easy to use multiple maps on
   533 different computers or export them to HTML in future.
   534 
   535 \subsection{Multiple maps} \label{tabs}
   536 You can work on multiple maps at the same time. Each new map is opened
   537 in another {\em tab}. The available tabs are shown just above the
   538 mapeditor. You can use the normal cut/copy/paste functions to
   539 copy data from one map to another.

   554 \section{Noteeditor} \label {noteeditor}
   555 If you want to save more text in a branch e.g. a complete email, a
   556 cooking recipe, or the whole source code of a software project, you can
   557 use the noteeditor. 
   558 \begin{center}
   559 	\includegraphics[width=8cm]{noteeditor.png}
   560 \end{center}
   561 This editor displays text associated to a branch selected in the
   562 mapeditor. To visualize that there maybe is no text yet, the noteeditor
   563 shows different background colors depending on its state:
   564 
   565 \subsection{States}
   566 Before you can type or paste text into it, you have
   567 to select a branch in the mapeditor. Note that the background color
   568 of the noteeditor indicates its state:
   569 \begin{itemize}
   570 	\item black: no branch selected
   571 	\item grey: no text entered yet
   572 	\item white: text is already available
   573 \end{itemize}	
   574 To show you in the mapeditor itself that there is a note with more
   575 information for a particular branch, a little note flag will appear next
   576 to the heading of the branch. See the lower branch on the right side:
   577 \begin{center}
   578 	\includegraphics[width=8cm]{branches-flags.png}
   579 \end{center}
   580 
   581 \subsection{Import and export notes}
   582 The note is always saved automatically within the \vym file itself.
   583 Nevertheless sometimes it is nice to import a note from an external file
   584 or write it. Use "File\ra~Import" and "File\ra~Export" to do so. 
   585 
   586 \subsection{Edit and print note}
   587 Editing works like in any simple texteditor, including undo and redo
   588 functions. You can delete the complete note by clicking the
   589 trashcan. Only the note itself is printed by clicking the printer icon.
   590 
   591 When pasting into the editor using the X11 copy\&paste mechanism, the
   592 editor will create a paragraph for each new line. Usually this is not
   593 wanted, so there you can convert all paragraphs into linebreaks by using
   594 Edit~\ra~Remove~Paragraphs or \key{ALT-X}.
   595 
   596 \subsection{RichText: Colors, paragraphs and formatted text}
   597 \vym supports formatted text (QT Rich Text) in the noteeditor since
   598 version 1.4.7.  Colors and text attributes (e.g. italic, bold) can be
   599 set with the buttons above the text.  The text itself is divided in
   600 paragraphs. For each paragraph the format can be set (e.g. centered,
   601 right). A paragraph is ended when a \key{Return} is entered. If you just
   602 want to begin a new line, press \key{CTRL-Return}.
   603 
   604 \subsection{Fonts and how to quickly switch them}
   605 The noteeditor is ment to be used for simple notes, not really as full
   606 featured text editor. Because of many requests \vym supports now
   607 formatted text in the noteeditor\footnote{
   608 	\vym uses the QRichtText format, which is basically a subset of the
   609 	formatting provided in HTML.}
   610 Two default fonts are supported which can be set in the Settings menu.
   611 One is a fixed width font, the other has variable width. The fixed font
   612 is usually used for emails, source code etc.\ while the variable font is
   613 used for simple notes, where one doesn't need fixed character widths.
   614 Both fonts can easily switched using the following symbol from the
   615 toolbar:
   616 \begin{center}
   617 	\includegraphics[width=0.5cm]{formatfixedfont.png}
   618 \end{center}
   619 In the Settings menu both fonts can be set and also which font should be
   620 used for default. 
   621 
   622 Additionally to the default fonts any font installed on your system can
   623 be used. Please note, that the chosen font also will be used for HTML
   624 exports, so you should only use fonts which are available generally.
   625 
   626 \subsection{Find text}
   627 The noteeditor itself has no Find function, use Find in the mapeditor,
   628 which will also search all notes (see \ref{findwindow}).
   629 
   630 \subsection{Paste text into note editor}
   631 Often you will paste text into the editor from another application e.g.
   632 an email. Normally \vym will generate a new paragraph for each new line.
   633 This usually is not what you want, so you can choose from the menu
   634 
   635 \subsection{Advanced actions}
   636 \subsubsection*{Edit \ra Convert subsubsections:}
   637 This turns subsubsections in selected text (or all text, if nothing is
   638 selected) into linebreaks. This is especially useful for snippets of
   639 source code.
   640 
   641 \subsubsection*{Edit \ra Join Lines:}
   642 Tries to format text, so that empty lines are used to delimit
   643 paragraphs. This is done for selected text (or all text, if nothing is
   644 selected). Especially useful for text like emails, meeting minutes etc.
   645 
   646 \section{Hello world}
   647 This section is about how \vym can interact with other applications.
   648 Many applications meanwhile can read and write their data using XML, the
   649 eXtensible Markup Language. \vym also uses XML to save its maps, see
   650 \ref{fileformat} for a more detailed description. 
   651 
   652 So if your an application understands XML, chances are good that someone
   653 could write import/export filters for \vym. Volunteers are always
   654 welcome ;-)
   655 
   656 \subsection{Import} \label{import}
   657 
   658 \subsubsection*{KDE Bookmarks}
   659 The integrated bookmark editor in KDE is somewhat limited, so why not
   660 use \vym to maintain the bookmark mess? To create a new map containing
   661 your current KDE bookmarks just choose
   662 \begin{itemize}
   663 	\item File \ra Import\ra KDE Bookmarks
   664 \end{itemize}
   665 
   666 \subsubsection*{Mind Manager}
   667 \vym has currently a very basic import filter to convert maps created by
   668 {\em Mind Manager}\footnote{Mind Manager is a professional software by
   669 Mindjet. Both names are registered trademarks by Mindjet. For more
   670 information see their website at
   671 \href{http://mindjet.de}{http://mindjet.de}} into \vym maps. Notes and
   672 pictures are not converted at the moment. You can import files with
   673 \begin{itemize}
   674 	\item File \ra Import\ra Mind Manager
   675 \end{itemize}
   676 
   677 
   678 \subsubsection*{Directory structure}
   679 \vym can read a directory structure. This is mainly for
   680 testing \vym e.g. to easily create huge maps used for benchmarks (yes,
   681 there is still room to optimize \vym ;-)
   682 
   683 
   684 
   685 
   686 \subsection{Export}  \label{export}
   687 \label{hideexport}
   688 Often you don't want to export the whole map, but just parts of it. For
   689 example you may have additional info you want to talk about in a
   690 presentation, while those parts should not be visible to the audience.
   691 To achieve this you can "hide" parts of the map during exports by
   692 setting the "hide in export" flag.
   693 \begin{center}
   694 	\includegraphics[width=0.5cm]{flag-hideexport.png}
   695 \end{center}
   696 You can toggle this flag in the toolbar or by pressing \key{H}.
   697 Note that there is a global option in the settings menu to toggle the
   698 use of this flag. By default the flag is enabled.
   699 
   700 \subsubsection*{Open Office}
   701 Open Office beginning with version~2 uses the so called "Open Office
   702 Document Format", which can be written by \vym. The options are
   703 currently limited, but it possible to export presentations which can be
   704 opened in Open Office Impress. By selecting
   705 \begin{itemize}
   706 	\item File \ra Export\ra Open Office
   707 \end{itemize}
   708 you get a file dialogue where you can choose the output file and the
   709 file type:
   710 \begin{center}
   711 	\includegraphics[width=12cm]{export-oo.png}
   712 \end{center}
   713 The file types represent various templates, which can be created with
   714 some manual work from an existing Open Office document. The structure of
   715 \vym map is then inserted into a template. 
   716 There are some limitations at the moment:
   717 \begin{itemize}
   718 	\item \vym can't take care of page lengths, so you have to check and
   719 	probably reedit in Open Office to avoid text running over the end of
   720 	a page
   721 	\item Images and flags are not used at the moment
   722 	\item Notes are just written as plain text, without RichText
   723 \end{itemize}
   724 Some of the templates make use of {\em sections} e.g. insert the
   725 headings of mainbranches as chapters for sections into the presentation.
   726 
   727 \subsubsection*{Image}
   728 \vym supports all image formats which are natively supported by the
   729 QT~toolkit:
   730 BMP, JPEG, PBM, PGM, PNG, PPN, XPM, and XBM.
   731 For use in websites and for sending images by email PNG is a good
   732 recommodation regarding quality and size of the image. \vym uses QTs
   733 default options for compressing the images.
   734 
   735 \subsubsection*{ASCII}
   736 Exporting an image as text is somewhat experimental at the moment. Later
   737 this will probably done using stylesheets. So the output may change in
   738 future versions of \vym.
   739 
   740 \subsubsection*{\LaTeX}
   741 \vym can generate an input file for \LaTeX. Currently this is considered
   742 as experimental, there are no options (yet). 
   743 By selecting
   744 \begin{itemize}
   745 	\item File \ra Export\ra \LaTeX 
   746 \end{itemize}
   747 you will be asked in a file dialog for the name of the output file. This
   748 file should be included in a \LaTeX document using command  
   749 \begin{verbatim}
   750 	\include{inputfile.tex}
   751 \end{verbatim}
   752 
   753 \subsubsection*{KDE Bookmarks}
   754 \vym will overwrite the KDE bookmarks file and then try to notify
   755 running konquerors via DCOP of the changed file. \vym does not create a
   756 backup!
   757 \begin{itemize}
   758 	\item File \ra Export \ra KDE Bookmarks
   759 \end{itemize}
   760 
   761 
   762 \subsubsection*{XHTML (Webpages)}
   763 
   764 This is the format you want to use to create a webpage. For an example
   765 have a look at the \vym homepage: 
   766 \href{http://www.InSilmaril.de/vym}{www.InSilmaril.de/vym}
   767 
   768 Some explanation how this works: 
   769 Before a map is exported as XHTML, it will be first written as XML into a
   770 directory (see \ref{xmlexport}). Then the external program {\tt
   771 xsltproc}\footnote{On SUSE Linux {\tt xsltproc} is installed by
   772 default.}
   773 will be called to process the XML file and generate HTML code.
   774 A dialog allows to set various options:
   775 \begin{itemize}
   776 	\item {\bf Include image:} If set, \vym will creat an image map at
   777 	the top of the HTML output. Clicking on a branch in the map will
   778 	jump to the corresponding section in the output.
   779 
   780 	\item {\bf Colored headings:}
   781 	If set to yes, \vym will color the headings in the text part  with the
   782 	same colors like in the map.
   783 	\item {\bf Show Warnings:}
   784 	If set to yes, \vym will ask before overwriting data.
   785 	\item {\bf Show output:}
   786 	This is useful mainly for debugging. It will show how the processing of
   787 	the XML file works by calling the external {\tt xsltproc}.
   788 \end{itemize}
   789 Additionally the paths to the CSS and XSL stylesheets can be set. By
   790 default on SUSE~Linux they will be in {\tt /usr/share/vym/styles}.
   791 
   792 
   793 \subsubsection*{XML} \label{xmlexport}
   794 The map is written into a directory both as an image and as XML. The
   795 directory is set in a file dialog. If the directory is not empty, you
   796 will be questioned if you risk to overwrite its contents.
   797 
   798 It is possible to export different maps into the same directory. Each
   799 file generated will have the map's name as prefix, e.g. {\tt todo.vym}
   800 becomes {\tt todo.xml}, {\tt todo.png}, {\tt todo-image-1.png} and so
   801 on. This is useful if e.g. for a website several combined maps have to
   802 be stored in the same directory.
   803 
   804 \subsubsection*{Export a part of a map}
   805 Select a branch you want to export together with its childs, then open
   806 the context menu and choose {\em Save Selection}. This will create a
   807 file with the postfix {\tt .vyp}, which is an abbreviation for \lq vym
   808 part\rq.
   809 
   810 
   811 \section{Advanced Editing}
   812 
   813 \subsection{How to deal with Bookmarks} \label{bookmarks}
   814 \subsubsection*{Open new tabs instead of new windows}
   815 If you use konqueror as browser, \vym will remember the konqueror which
   816 was opened first by \vym. You can also press \key{Ctrl} and click to
   817 open the link in a new tab then.
   818 
   819 \vym can also open a new tab in Mozilla or Firefox using the remote
   820 command\footnote{\href{http://www.mozilla.org/unix/remote.html}{http://www.mozilla.org/unix/remote.html}}
   821 of these.
   822 
   823 \subsubsection*{Drag and Drop}
   824 If you want to keep bookmarks in a map, select a branch where you want
   825 to add the bookmark, then simply drag the URL from your browser to the
   826 map. Also you could use an existing heading as URL: Right click onto the
   827 branch and select "Use heading for URL".
   828 
   829 
   830 \subsubsection*{Directly access bookmark lists of a browser}
   831 Please see the sections \ref{import} and \ref{export} about
   832 Import and Export filters.
   833 
   834 \subsubsection*{Special URLs}
   835 \vym can turn an existing heading of a branch into an URL. Currently
   836 this works for Bugentries in the Novell Bugtracking system: Open the
   837 context menu of a branch (usually by right-clicking it) and select
   838 \begin{itemize}
   839 	\item Create URL to Bugzilla
   840 \end{itemize}
   841 The URL will be build from the number in the heading.
   842 
   843 \subsection{Including images into a branch} 
   844 The default setting of an image is to float "freely". They can be
   845 positioned everywhere, but they might end up in the same place as other
   846 parts of the map.
   847 
   848 The solution is to include them "into" a branch. This can be done via
   849 the context menu of their parent branch:
   850 \begin{itemize}
   851 	\item Include images horizontally
   852 	\item Include images vertically
   853 \end{itemize}
   854 The image ist still positioned relatively to its parent branch, but the
   855 heading and border of the branch adapt to the floating image, see below: 
   856 \begin{center}
   857 	\includegraphics[width=11cm]{includeImages.png}
   858 \end{center}
   859 
   860 \subsection{Modifier Modes} 
   861 Modifiers are for example the \key{Shift}- or the \key{Alt}-keys. When
   862 pressed while doing actions with the mouse, they will cause \vym to use
   863 a "modified" action. E.g. you can move branches with mouse. If
   864 \key{Ctrl} or \key{Alt}is pressed while releasing the branch, it will be
   865 added above/below the target, not as child of the target.
   866 
   867 Without a modifier pressed, the first click on a branch just selects
   868 it. For the behaviour of the \key{Ctrl} modifier there are several
   869 options, which can be set from the modifier toolbar:
   870 \begin{center}
   871 	\includegraphics[width=3cm]{modmodes.png}
   872 \end{center}
   873 The default  is to copy the color from the clicked branch to the already
   874 selected branch. In the toolbar shown above the default modifier is
   875 selected, namely to copy the color of a branch. The second modifier
   876 let's you easily copy a whole branch with a single click. The third
   877 modifier lets you create {\em xLinks}, which will be explained in the
   878 next section.
   879 
   880 \subsection{Hide links of unselected objects}
   881 Sometimes it would be useful to position a branch freely, just like a
   882 mainbranch or an image. Though this is not possible (yet) for all
   883 branches, you can use a mainbranch and hide its connecting link to the
   884 mapcenter. This can be used e.g. for legends or a collection of vymLinks
   885 pointing to other maps:
   886 \begin{center}
   887 	\includegraphics[width=9cm]{hiddenlink.png}
   888 \end{center}
   889 
   890 
   891 \subsection{XLinks} \label{xlinks}
   892 So far all the data in the \vym map has been treelike. Using xLinks you
   893 can link one branch to any other, just like attaching a rope between two
   894 branches in a real tree. This is especially useful in complex maps,
   895 where you want to have crossreferences which don't fit on the same
   896 visible area, which fits on your screen. The following example, which is
   897 part of the \vym package, still fits on one screen, but shows how data
   898 can be crosslinked. In the graphics there is a link from a task (prepare
   899 a presentation) to general information:
   900 \begin{center}
   901 	\includegraphics[width=12cm]{xlink.png}
   902 \end{center}
   903 Note that a xLink which points to a branch that is not visible (because
   904 it is scrolled), is just show as a little horizontal arrow. In the
   905 screenshot above have a look at the \lq Tuesday\rq\ branch.
   906 
   907 \subsubsection*{Create a xLink}
   908 Choose the link mode from the modifier toolbar (by clicking or pressing
   909 \key{L}). Select the branch, where the xLink should start. Press the
   910 modifier key \key{Ctrl} and simultanously click on the branch where the
   911 link should end. (The link is already drawn before you release the mouse
   912 key). If you release the mouse over a branch the xLink becomes
   913 permanent.
   914 
   915 \subsubsection*{Modify or delete a xLink}
   916 Open the context menu of a branch and select \lq Edit xLink\rq. A
   917 submenu contains all the xLinks of the branch (if there are any). They
   918 are named like the branches, where they end. Choose one and
   919 the xLink dialogue opens, where you can set color, width and also delete
   920 the xLink.
   921 
   922 \subsubsection*{Follow a xLink}
   923 In a complext \vym map it sometimes comes handy to jump to the other end
   924 of a xLink. You can do this by opening the context menu of the branch
   925 and clicking on \lq Goto xLink\rq and selecting the xLink you want to
   926 follow.
   927 
   928 
   929 
   930 \subsection{Adding and removing branches}
   931 The context menu of a branch shows some more ways to add and delete data
   932 e.g. you can delete a branch while keeping its childs. The childs become
   933 linked to the parent of the previously removed branch.
   934 Similar branches can be inserted into existing maps. For keyboard
   935 shortcuts also have a look at the context menu.
   936 
   937 \subsection{Adding a whole map or a part of a map}
   938 Select a branch where you want to add a previously saved map ({\tt .vym})or a part
   939 of a map ({\tt .vyp}) , then open
   940 the context menu and choose {\em Add \ra Import}. For the import you can
   941 choose between {\em Import Add} and {\em Import Replace}: The imported
   942 data will be added after the selection resp. replace the selection.
   943 
   944 
   945 \section{\vym on Mac OS X}
   946 \subsection{Overview}
   947 Basically there are two ways to run \vym on Macs:
   948 \subsubsection*{QT Mac Edition:}
   949 	\vym here provides the well known Mac look and feel.  \vym is
   950 	available as zipped Mac OS X application. It has been compiled and
   951 	tested in Mac~OS~10.3, but should also work on Tiger. It is using
   952 	the Mac version of Trolltechs QT library.  
   953 \subsubsection*{X11}
   954 	\vym can also be run using the Linux version, but then menus and
   955 	handling will also be those of the Linux version e.g. The menu bar
   956 	will look different. 
   957 
   958 \subsection	{Contextmenu and special keys}
   959 Most Macs unfortunatly just have a single mouse button. In order to show
   960 the context menu which usually would be opened with the right mouse
   961 button, you can click while pressing the \key{kommand}-key.
   962 
   963 Especially on Laptops some of the keys usually used on PC keyboards seem
   964 to be missing. The QT-Mac Edition of \vym has its own keyboard
   965 shortcuts. To find the shortcuts just have a look at all the menu
   966 entries, the shortcut is visible next to an entry. Toolbar buttons also
   967 may have shortcuts, just position the mouse pointer over a button and
   968 wait for the little help window to appear. 
   969 
   970 \subsection {Viewing external links}
   971 \vym on Mac uses the system call {\tt /usr/bin/open} to view links.
   972 Mac~OS determines automatically if the link is a pdf or www page and
   973 opens the right browser.
   974 
   975 
   976 \begin{appendix}
   977 
   978 \section{Starting \vym}
   979 \subsection{Path to ressources}
   980 \vym will try to find its ressources (images, stylesheets, filters,
   981 etc.) in the following places:
   982 \begin{enumerate}
   983 	\item Path given by the environment variable {\tt VYMHOME}.
   984 	\item If called with the local option (see \ref{options} below),
   985 	      \vym will look for its data in the current directory.
   986 	\item {\tt /usr/share/vym}
   987 	\item {\tt /usr/local/share/vym}
   988 \end{enumerate}
   989 
   990 \subsection{Command line options} \label{options}
   991 \vym has the following options:
   992 \begin{center}
   993 \begin{tabular}{ccp{8cm}}\\ 
   994 \bf Option	& \bf Comment & \bf Description \\ \hline
   995 v & version & Show version ov \vym\\
   996 l & local	& Use local paths to stylesheets, translations, icons, 
   997               etc. instead of system paths. Useful for testing\\
   998 h & help	& Show help\\
   999 q & quit	& Quit immediatly after startup. Useful for benchmarks.\\
  1000 \end{tabular}
  1001 \end{center}
  1002 You can also give several filenames at the commandline to let \vym open
  1003 several maps at once.
  1004  
  1005 \section{Contributing to \vym}
  1006 So far I'd say I have written 98\% of the code on my own. No surprise,
  1007 that \vym exactly fits my own needs. Nevertheless I would like to
  1008 encourage all users of  \vym to contribute. Maybe not only with feature
  1009 requests, but also with code, new import/export filters, translations
  1010 etc. In this appendix I'll try to show how easy it is to expand the
  1011 things you can do already with \vym. I really look forward to hear from
  1012 you!
  1013 
  1014 \subsection{Getting help}
  1015 
  1016 \subsubsection*{Frequently asked questions}
  1017 Please refer to the FAQ available on the \vym website:
  1018 \begin{center}
  1019 \href{http://www.InSilmaril.de/vym/faq.html}{http://www.InSilmaril.de/vym/faq.html}
  1020 \end{center}
  1021 
  1022 \subsubsection*{Mailinglists}
  1023 There are two mailinglists: {\tt vym-forum} is the \vym users forum to
  1024 discuss various questions, while {\tt vym-devel} is intended for people
  1025 interested in contributing to \vym. You can view the archives and
  1026 subscribe at
  1027 \begin{center}
  1028 \href{https://sourceforge.net/mail/?group_id=127802}{https://sourceforge.net/mail/?group\_id=127802}
  1029 \end{center}
  1030 
  1031 \subsubsection*{Contacting the author}\label{author}
  1032 Especially for support questions please try the mailinglists first. If
  1033 everything else fails you can contact the Uwe Drechsel at
  1034 \begin{center}
  1035 \href{mailto:vym@InSilmaril.de}{vym@InSilmaril.de}
  1036 \end{center}
  1037 
  1038 
  1039 
  1040 \subsection{How to report bugs}
  1041 Though Sourceforge has its own bugreporting system, I'd rather prefer if
  1042 you contact me directly (see \ref{author}) or even better: You can file
  1043 a bugreport in Bugzilla, the bugtracking system of openSUSE:
  1044 \begin{center}
  1045 \href{http://en.opensuse.org/Submit_a_bug}{http://en.opensuse.org/Submit\_a\_bug}
  1046 \end{center}
  1047 I build \vym regulary for openSUSE, so you may report it against a
  1048 recent version there, even if you  use another Operating System.
  1049 Please don't forget to tell 
  1050 \begin{itemize}
  1051 	\item the exact steps needed to reproduce the bug
  1052 	\item the version and build date of \vym (see the Help \ra About
  1053 	\vym)
  1054 	\item hardware and Operating System
  1055 \end{itemize}
  1056 
  1057 \subsection{Compiling from the sources}
  1058 \subsubsection{Getting the sources} \label{getsources}
  1059 You find the latest version of \vym at the project site:
  1060 \begin{center}
  1061 \href{https://sourceforge.net/projects/vym/}{https://sourceforge.net/projects/vym/}
  1062 \end{center}
  1063 There you can check them out of the source repository (CVS):\\
  1064 
  1065 \begin{verbatim}
  1066 cvs -d:pserver:anonymous@cvs.sf.net:/cvsroot/vym checkout code
  1067 \end{verbatim}
  1068 
  1069 \subsubsection{The Qt toolkit}
  1070 Qt is C++ toolkit for multiplatform GUI and application development. It
  1071 provides single-source portability across MS~Windows, Mac~OS~X, Linux
  1072 ans all major commercial Unix variants. Qt is also available for
  1073 embedded devices. Qt is a Trolltech product. For more information see 
  1074 \begin{center}
  1075 \href{http://www.trolltech.com/qt/}{www.trolltech.com/qt} 
  1076 \end{center}
  1077 
  1078 
  1079 \subsubsection{Compiling \vym }
  1080 Make sure you have installed your Qt environment properly, see the Qt
  1081 documentation for details. You need to have the Qt command {\tt qmake}
  1082 in your {\tt PATH}-environment, then run
  1083 \begin{verbatim}
  1084 qmake
  1085 make  
  1086 make install
  1087 \end{verbatim}
  1088 The last command {\tt make install} needs root-permissions. Of course it
  1089 may be omitted, if you just want to test \vym.
  1090 
  1091 %\subsubsection*{Compiling \vym on Macs}
  1092 %TODO
  1093 
  1094 \subsection{\vym file format} \label{fileformat}
  1095 \vym maps usually have the postfix "{\tt .vym}" and represent a
  1096 compressed archive of data. If you want to have a
  1097 closer look into the data structure map called "mapname.vym", 
  1098 just uncompress the map manually using
  1099 \begin{verbatim}
  1100 	unzip mapname.vym
  1101 \end{verbatim}
  1102 This will create directories named {\tt images} and {\tt flags} in your
  1103 current directory and also the map itself, usually named {\tt
  1104 mapname.xml}.
  1105 The XML structure of \vym is pretty self explaining, just have a look at
  1106 {\tt mapname.xml}.
  1107 
  1108 This XML file can be loaded directly into \vym, it does not have to be
  1109 compressed. If you want to compress all the data yourself, use
  1110 \begin{verbatim}
  1111 	zip -r mapname.vym .
  1112 \end{verbatim}
  1113 to compress all data in your current directory.
  1114 
  1115 \subsection{New features}
  1116 There are lots of features which might find their way into \vym.
  1117 Together with \vym you should have received a directory with several
  1118 maps e.g. on SUSE~LINUX this is
  1119 \begin{center}
  1120 	{\tt /usr/share/doc/packages/vym/demos}
  1121 \end{center}
  1122 where you find the map {\tt todo.vym}. It lists quite a lot of things to
  1123 be done in future. If you have more ideas, contact the development team
  1124 at
  1125 {\tt vym-devel@lists.sourceforge.net}.
  1126 
  1127 
  1128 \subsection{New languages support}
  1129 In order to add a new language to \vym you need 
  1130 the sources (see \ref{getsources}) and
  1131 an installation of Trolltechs QT. A part of QT are the development
  1132 tools, from those tools especially the translation tool "Linguist" is
  1133 needed. 
  1134 
  1135 In some Linux distributions the development tools are in an extra package, e.g. on SUSE LINUX you should have installed:
  1136 \begin{verbatim}
  1137     qt3-devel.rpm
  1138     qt3-devel-doc.rpm
  1139     qt3-devel-tools.rpm
  1140     qt3-man.rpm
  1141 \end{verbatim}
  1142 If you don't have QT in your system, you can get it from 
  1143 	\href{http://www.trolltech.com}{http://www.trolltech.com} Once you
  1144 	are able to compile vym yourself, you can translate the text in vym
  1145 	itself by performing the following steps:
  1146 \begin{itemize}
  1147 	\item Let's assume now your encoding is "NEW" instead of for example
  1148 	"de" for german or "en" for english
  1149 	
  1150 	\item Copy the file {\tt lang/vym\_en.ts} to l{\tt ang/vym\_NEW.ts} (The code
  1151 	itself contains the english version.)
  1152 		
  1153 	\item Add {\tt lang/vym\_NEW.ts} to the TRANSLATIONS section of vym.pro
  1154 
  1155 	\item Run Linguist on {\tt vym\_NEW.ts} and do the translation
  1156 
  1157 	\item Run {\tt lrelease} to create {\tt vym\_NEW.qm}
  1158 
  1159 	\item Do a make install to install the new vym and check your translation
  1160 \end{itemize}
  1161 
  1162 If you feel brave, you can also translate the manual. It is written in
  1163 LaTeX, you just have to change the file tex/vym.tex. (Linguist and QT
  1164 are not needed, but it is useful to know how to work with LaTeX and esp.
  1165 pdflatex to create the PDF.) 
  1166 
  1167 Please mail me every translation you have done. I can also give you a
  1168 developer access to the project, if you want to provide translations
  1169 regulary.  
  1170 
  1171 \subsection{New export/import filters}
  1172 \vym supports various kinds of filters. Data can be written directly,
  1173 inserted into templates or it can be written as XML data and then
  1174 processed by XSL transformations. 
  1175 
  1176 Most of the import/export functionality is available in the classes
  1177 ImportBase and ExportBase and subclasses. All of them can be found in
  1178 {\tt imports.h} and {\tt exports.h}.
  1179 
  1180 \subsubsection*{Direct import/export}
  1181 An example for a direct export is the XML export. This method touches
  1182 the implementation of nearly every object of \vym, so whenever possible
  1183 you should better use a XSL transformation instead.
  1184 
  1185 If you still want to know how it is done, start looking at 
  1186 {\tt MapEditor::saveToDir} in {\tt mapeditor.cpp}.
  1187 
  1188 \subsubsection*{Templates}
  1189 Templates have been introduced to export to opendoc format used e.g. by
  1190 Open~Office. While I read the spec ($>$ 500 pages) about the format\footnote{
  1191 \href{http://www.oasis-open.org/}{http://www.oasis-open.org/}}\ 
  1192 I had the feeling that I did not want to write the export from scratch. 
  1193 It would be too complex to adapt the styles to your own wishes, e.g. the
  1194 layout.
  1195 
  1196 Instead I analyzed existing Open~Office documents. I found out that
  1197 there are lots of redundant bits of information in a standard
  1198 presentation, for example each list item is contained in its own list.
  1199 In the end I came up with the default presentation style, which still
  1200 could be simplified, just in case you have free time\ldots
  1201 
  1202 The existing templates are still work in progress, before you spent too
  1203 much time developing your own style, please contact me.  Basically the
  1204 following steps are needed to build your own style:
  1205 \begin{enumerate}
  1206 	\item Create an example in Open Office. Use a title, authors name,
  1207 	page heading etc.\ which you can easily grep for in the output file.
  1208 	
  1209 	\item Unzip  the Open Office document into a directory.
  1210 
  1211 	\item The main file is called {\tt content.xml}. All data is in one
  1212 	single line. You can split the XML tags using the script {\tt
  1213 	scripts/niceXML}, which is part of the \vym distribution.
  1214 
  1215 	\item Copy the output of {\tt niceXML} to {\tt
  1216 	content-template.xml}.
  1217 
  1218 	\item Looking closer you will find lots of unused definitions, for
  1219 	example of styles. You can delete or simply ignore them.
  1220 
  1221 	\item Try to find your title, authors name. \vym will replace the
  1222 	following strings while exporting:
  1223 	\begin{center}
  1224 	\begin{tabular}{lp{4cm}}
  1225 		{\tt <!-- INSERT TITLE -->}		& title of map \\
  1226 		{\tt <!-- INSERT AUTHOR-->	}	& author \\
  1227 		{\tt <!-- INSERT COMMENT -->}	& comment \\
  1228 		{\tt <!-- INSERT PAGES-->}		& content of map \\
  1229 	\end{tabular}
  1230 	\end{center}
  1231 	The content itself is generated in a similar way by inserting lists
  1232 	into {\tt page-template}. Here the following substitutions are made:
  1233 	\begin{center}
  1234 	\begin{tabular}{lp{7cm}}
  1235 		{\tt <!-- INSERT PAGE HEADING-->}		& heading of a page
  1236 		(mainbranch or child of mainbranch, depending on the use of
  1237 		sections) \\
  1238 		{\tt <!-- INSERT LIST -->	}	& all childs of the branch above \\
  1239 	\end{tabular}
  1240 	\end{center}
  1241 \end{enumerate}
  1242 Currently images are exported and notes just will appear as text
  1243 without formatting and colors.
  1244 
  1245 
  1246 
  1247 
  1248 \subsubsection*{XSL Transformation}
  1249 \vym uses XSL transformations while exporting (e.g. XHTML) and importing
  1250 data (e.g. KDE bookmarks). There is a little code needed to provide the
  1251 GUI, the rest is done using the {\tt .xsl} stylesheet and calling the
  1252 {\tt xsltproc} processor, which is part of libxslt, the XSLT
  1253 C  library  for  GNOME.
