\section{Introduction}
\subsection{What is a \vym map?}
A \vym map (abbreviated below as {\em map}) is a tree like structure:
\maximage{images/example1.png}
Such maps can be drawn by hand on a sheet of paper or flip chart and help to
structure your thoughts. While a tree like structure like the illustration above can be
drawn manually \vym offers much more features to work with such maps.
\vym is not just another drawing software application, but a tool to store and modify
information in an intuitive way. For example you can reorder parts of
the map by pressing a key or add various pieces of information like a complete
email by a simple mouse click.

Once you have finished collecting and organising your ideas, you can
easily generate a variety of outputs including for example a
presentation in Open~Office based on a {\em map}.

\hint{You find the map shown above and others by clicking \begin{center}Help \ra Open vym
examples\end{center} in the menu bar.}

\subsection{Why should I use {\em maps}? Time, Space and your Brain.}
\subsubsection*{Space}
A {\em map} can concentrate very complex content in a small space such as a
piece of paper. It helps to use both sides of your brain: the logical
side and also your creative side (e.g. by using pictures, colours and
keywords in a map, often called {\em anchors}).  It is a technique to help
organize the way you think and stimulate your creativity: It can help you by developing, sorting and helping to memorise your ideas. 

\subsubsection*{Time}
Because you just use keywords and drawings, it is much faster than good
old fashioned 'notes'. Your brain memorizes things by associating them with
other things -- a {\em map} makes use of those connections and stimulates
new asccociations. 


\subsubsection*{Your Brain}
In 1960 Prof. {\sc Roger Sperry} discovered that both hemispheres
of the human brain undertake different tasks (of course both of them
basically {\em can} do the same): 
\begin{center}
\begin{tabular}{|p{5.5cm}|p{5.5cm}|} \hline
	Left side & Right side \\ \hline
	\begin{itemize}
	   \item verbal speech and writing 
	   \item numbers
	   \item logical thinking
	   \item analysing and details
	   \item science
	   \item linear thinking
	   \item concept of time
	\end{itemize} &
	\begin{itemize}
		\item body language
		\item visual thinking, day dreams
		\item intuition and emotion
		\item overview of things
		\item creativity
		\item art, music, dancing
		\item non-linear thinking, connecting things
		\item spatial awareness
	\end{itemize}     \\ \hline
\end{tabular}	
\end{center}
In our science oriented western society we have learned to mainly rely on our
left side of the brain, the "rational" one. In other cultures, such as the native americans and other "old" cultures, the right
side is much more important. {\em Map} are just one way to stimulate the
other side and make use of additional resources we all have.


\subsection{Where could I use a {\em map}?}
Here are some examples, how you can use those {\em maps}
\begin{itemize}
    \item to prepare articles, papers, books, talks, \ldots
    \item to sort complex data
    \item to memorize facts, peoples names, vocabulary, \ldots
    \item to sort emails, files and bookmarks on your computer
    \item to moderate conferences
    \item to brainstorm solutions to problems
    \item to record the tasks when planning a project
\end{itemize}

\subsection{What you shouldn't do with a {\em map}...}
A {\em map} drawn by somebody shows the way that the author thinks. There is
no question of right or wrong in the way it is drawn, so there is no way to criticise
it. "It is, what it is" ({\sc F.~Lehmann}).The tool will be of considerable use to the author and only very limited use to anyone else. 

However, when groups share in creating a {\em map} all of the group will benefit from its use. An example of such use is when a Tutor develops a {\em map} with a group of students during instruction. Another group use is when a Project leader gathers a group of specialists to help {\em map} the tasks that will be required to deliver a project.

\subsection{Internet Ressources} 
A good starting point to learn more about Mindmaps in general is Wikipedia:
\begin{itemize}
	\item English: 
		\href{http://en.wikipedia.org/wiki/Mind_map}{http://en.wikipedia.org/wiki/Mind\_map}
	\item German: 
		\href{http://de.wikipedia.org/wiki/Mindmap}{http://de.wikipedia.org/wiki/Mindmap}
\end{itemize}




\section{The Concept of the \vym application}
%TODO may add a general introduction here...
\subsection{The Mainwindow and its satellites} \label{satellite}
\vym comes with several windows, the central one being the {\em
mapeditor}.
More windows, each having a special purpose, can be opened and arranged
around the mainwindow\footnote{
	The advantage of having separate window instead of integrating them
	in a combined workspace is flexibility in arranging the windows. For
	example I usually have the {\em noteeditor} "behind" the {\em
	mapeditor}. On Linux my windowmanager (KDE) allows me to enter text
	into a small visible corner of the {\em noteeditor} withour clicking
	the mouse button in it. I just push the mouse around to set the
	window focus, a concept which is useful also working with 
	\href{http://www.gimp.org}{http://www.gimp.org}.
}. 
The image below shows the {\em mapeditor}
together with the often used {\em noteeditor}: 
\maximage{images/windows.png}
Most of the time you will work in the {\em mapeditor} by just adding new
branches, moving around and reordering them. The various ways to do this
will be explained in \ref{mapeditor}. You can store additional
information e.g. the content of a email easily in a {\em branch}: Just
type or copy\&paste it into the {\em noteeditor}. Working with notes is
explained in \ref{noteeditor}
 
Here is a list of the available satellite windows:
\begin{itemize}
	\item Noteeditor (see \ref {noteeditor})
	\item Historywindow (see \ref{historywindow})
	\item Branch Property Window (see \ref{propwindow})
\end{itemize}


\subsection{Menus and Context menus}
At the top of each window you will find the menubar. The options provided there
are similar to those you are probably used to from other applications. Note that
many (and even more) options are availabe via {\em context menus}. Those
are available if you right-click onto an object in a map (on Mac~OS~X
Command-Click).

\subsection{Toolbars}
The toolbars in the mainwindows give quick access to many functions and
also display the state of selected objects in the map. For example a
branch may show certain {\em flags}, the corresponding flags are also
set in the toolbar. 

\hint {You can reposition all toolbars by simply grabbing and
dragging them with the toolbar handle to a new position. For example you
can move the flags-toolbar from its original horizontal position on top
of the mapeditor to a vertical position on the right side.  Or just
insert it again at its original position. Also hiding some of the
toolbars is possible by right-clicking on the toolbar handle.}

\subsection{Maps}
The  {\em map} itself has always a {\em mapcenter}.  The
mapcenter has {\em branches} radiating out from the centre just like the trunk 
of a tree. Each branch in turn may have branches again.
	\maximage{images/branches.png}
We will call a branch directly connected to the mapcenter a {\em
mainbranch}, because it determines the position of all its child
branches.

The mapcenter and the branches all have a {\em heading}. This is the
text you see in the mapeditor. Usually it should just be one or a few
key words, so that one can easily keep track of the whole map.


In the toolbar above the mapeditor you see various symbols.
	\maximage{images/default-flags.png}
These are called {\em flags} and can be used to mark branches in the
{\em map}, e.g. if something is important or questionable. 
There are also more flags set by \vym automatically to show additional
information, e.g. when a note is attached to a  particular branch.

By default some of these flags are set exclusively e.g. when the 
"thumb-up" flag is set, then the "thumb down" is reset and vice
versa. You can change this default behaviour in the settings menu.

\section{Mapeditor} \label {mapeditor}
\subsection{Start a new map}
After \vym is started two windows will open: the {\em mapeditor} and the {\em noteditor}. Usually you will work in both windows, but at the moment we
will just need the mapeditor. 

Select the mapcenter "New map" in the middle of the mapeditor by
left-clicking with the mouse. It will be highlighted yellow to show that is
selected. There are several ways to add a new branch to the center:
\begin{itemize}
	\item Using the mouse: Open the context menu by clicking with the
	right mouse button (CTRL-Click on Mac) onto the
	mapcenter and choose Add \ra Add branch as child
	\item Press \key{Ins} or \key{A}
\end{itemize}
A new branch will appear and you will be able to type the heading of the
branch. Finish adding the new branch by pressing \key{Enter}.
%tipp
Sometimes it comes in handy to be able to add a new branch above or below the current
one. 
\begin{itemize}
	\item Use \key{Shift-A} to add a branch above the selected one or... 
	\item \key{Ctrl-A} to add one below. 
\end{itemize}
It is also
possible to add a branch in such a way, that the current selection
becomes the child of the new branch, which is like inserting it {\em
before} the selection. This can be done using the context menu.

\hint{To delete a branch press \key{CTRL-X}. If enabled in the Settings
menu, you can also use the \key{Del} key.}

\subsection{Navigate through a map}
\subsubsection*{Select branches}
To select branches you can use the left button of your mouse or also the
arrow keys. Depending on the {\em orientation} of a branch tap
\key{\la} or \key{\ra} to move nearer to the mapcenter or deeper
down into the branches. Within a set of branches, let's call them a 
{\em subtree}, you can use \key{\ua} and \key{\da} to go up and down. You can
also use \key{Home} and \key{End} to select the first and last branch.


\subsubsection*{Panning the view of a map}
While adding more and more branches the size of the map may become
larger than the mapeditor window. You can use the scrollbars on the
right and the bottom of your mapeditor window to scroll the view up or down or left or right. It is easier to just scroll using the left mouse button: Click anywhere on the {\em canvas} itself. Choose an empty space somewhere between the branches. The
mouse pointer will change from an arrow to a hand, now move or drag the visible
map to show the desired part.

If you select branches using the arrow keys, the map will scroll
to ensure that the selected branch is always visible.

\subsubsection*{Zooming the view of a map}
Working with huge maps, the {\em zoom}-function comes in handy: You can
use 
\begin{itemize}
	\item from the menu: View \ra Zoom in, View \ra Zoom out, View \ra reset Zoom.
	\item the toolbar buttons 
		\begin{center}
			\includegraphics[width=3cm]{images/zoom-buttons.png}
		\end{center}	
\end{itemize}	
Clicking the crossed magnifying lens icon will reset the zoomed view to its original size.


\subsubsection*{Find Function} \label{findwindow}
With huge maps there is the need to have a
find function. Choose Edit \ra Find to open the Find Window:
\begin{center}
	\includegraphics[width=6cm]{images/find-window.png}
\end{center}	
The find function will search for, the text you enter here, in all the branch headings and also in the associated notes. Everytime you press the "Find"-button it will look for the next occurence, which will then be selected automatically. If the search
fails, a short message "Nothing found" will appear for a few
seconds in the {\em statusbar} on the bottom of the mapeditor.

\subsubsection*{Keep the overview -- scroll a part of the map}
A very big subtree of a map e.g. a branch with hundreds of child branches would make
it very hard to keep an overview over the whole map. You can hide all
the children of a branch by {\em scrolling} it -- this function is often called {\em folding}. Think of the whole subtree as painted onto a
broadsheet newspaper. You can scroll or fold the paper to a small roll, leaving just
the headline visible.

To scroll or unscroll a branch and its children,
\begin{itemize}
	\item press either the \key{Scroll Lock} key or the \key{S}
	\item press the middle-mouse button or
	\item choose the scroll icon from the toolbar.
\end{itemize}
If you select parts of a scrolled branch e.g. using the find function or
by using the arrow-keys, it will unscroll temporary. This is shown as a
scroll with a little hour glass. If the temporary unscrolled part is no
longer needed, it will be hidden again automatically. It is also
possible to unscroll all branches using "Edit\ra Unscroll all scrolled
branches".

You can also hide parts of the map while exporting it e.g. to a webpage
or a presentation, see \ref{hideexport} for details.

\subsection{Modify and move branches}
\subsubsection*{Modify the heading}
You can edit the heading by selecting the branch and then
\begin{itemize}
	\item pressing \key{Enter}
	\item pressing \key{F2}
	\item double-clicking with left mouse.
\end{itemize}
Just type the new heading (or edit the old one) and press \key{Enter}.

\subsubsection*{Move a branch}
The easiest way to move a branch is to select it with left-mouse and
drag it to the destination while keeping the mouse button pressed.
Depending on the branch  it will be
\begin{itemize}
	\item moved to the destination or
	\item {\em linked} to a new {\em parent} (mapcenter or branch)
\end{itemize}
If you drag the branch over another one or over the mapcenter, you will
notice that the  link connecting it to the old parent will be changed to
lead to the  new parent which is now under your mousepointer. 
If you release the button now, the branch will be relinked.

If you release the button in the middle of nowhere, the result will
depend on the type of branch you are releasing:
\begin{itemize}
	\item A mainbranch is directly connected to the mapcenter.
		It will stay on its new position.
	\item An ordinary branch will "jump" back to its original position.	
\end{itemize}
Thus you can easily rearrange the layout of the mainbranches to avoid
overlapping of their subtrees.
There is another convenient way to move branches, especially if you want
to {\em reorder} a subtree: You can move a branch up or down in a
subtree by
\begin{itemize}
	\item pressing \key{\ua} and \key {\da}
	\item selecting Edit \ra Move branch
	\item clicking on the toolbar buttons:
		\begin{center}
			\includegraphics[width=1.5cm]{images/move-buttons.png}
		\end{center}	
\end{itemize}
%tipp
There is yet another way to move branches: If you press \key{Shift} or
\key{Ctrl} while moving with the mouse, the branch will be added above
or below the one the mouse pointer is over. This can also be used to reorder branches in a map.

\subsection{Colours and Images - Using the right side of your brain}
\subsubsection*{Change colour of a heading}
You can also use colours to add more information to a map, e.g. use
red, green and more colours to prioritize tasks. Again you can
\begin{itemize}
	\item use the menu and choose e.g Format \ra Set Color
	\item use the toolbar
		\begin{center}
			\includegraphics[width=3cm]{images/color-buttons.png}
		\end{center}	
\end{itemize}
The first button (black in the graphic above) shows the current colour.
Clicking on it let's you choose another colour. You can also "pick"
another colour by selecting a branch with the desired colour and using the
"pick colour" button. Both of the icons showing a palette actually apply
the current colour to the selected branch. While the first one just
colours the heading of the selection, the last one also colours all the
children of the selected branch.

%tipp
A very useful function is the "copy colour" using the mouse: Select the
branch which should get the new colour, then press \key{Ctrl} and
simultanously click with left-mouse on another branch to copy its colour
to the first one. Here the children of the selection also will get the new
colour, if you just want to colour the selection itself, additionally
press \key{Shift}.

\subsubsection*{Use flags}
\vym provides various flags. They are usually displayed in the toolbar on top of the
mapeditor window. (Note: Like all toolbars you can also move them to the
left or the right side of the window or even detach them. Just grab the
very left "dotted" part of the toolbar with your left-mouse button.) 
	\maximage{images/default-flags.png}
If you have a branch selected, you can set any number of flags by
clicking them in the toolbar. The toolbar buttons change their state and
always reflect the flags set in the selected branch. So, to remove a flag from a branch, select the branch and then click the highlighted flag on the toolbar.

At present \vym uses two kinds of flags: {\em System Flags} and {\em
Standard Flags}. The standard flags are those shown in the toolbar.
System flags are set by \vym to indicate e.g. that there is additional
information in a note (more on this in \ref{noteeditor}). Later versions
of \vym may have another kind of flags, which may be edited by the user.

\subsubsection*{Images}
The easiest way to add an image to a branch is by dragging it e.g. from a
webbrowser to the mapeditor while a branch is selected there.

You can also add an image to a branch by opening the context menu of the
branch. Right click the selected branch, choose "Add Image". A
dialog window enables you choose the image to load. 
\footnote{Supported image types are: PNG, BMP, XBM, XPM and PNM. It may
	also support JPEG, MNG and GIF, if specially configured during
	compilation (as done when \vym is part of SUSE LINUX).}
While an image is selected in the dialog, a preview of the
image is displayed. It is also possible to select multiple images.	

You can position the image anywhere you want, just drag it with left
mouse. To relink it to another branch, press \key{Shift} while moving
it. To delete it, press \key{Del}. 

If you right-click onto an image, a context menu will open which let's
you first choose one of several image formats. Then a file dialog opens
to save the image. 

Hint: This is used to "export" the image, it will be
saved anyway in the map itself! You can also cut and
copy images, but it is not possible to add objects to an image\footnote{
	Images are regarded as "extra feature". It would make working with
	the map much more complex if e.g. images could be linked to images.}

The option \lq{\bf Use for export} \rq controls the output of exports
e.g. to HTML: If set to no, the image won't appear in the {\em text}
part of the output. This is useful for large images or if images are
used as a kind of frame e.g. the famous cloud symbol around a part of
the map. Those shouldn't appear in the middle of the text.

At the moment image support is preliminary: Images will be saved
together with all the other data of a map in the {\tt .vym}-file.
Later versions will include more functionality like resizing the images,
changing its z-value (put it into background) etc.

\subsubsection*{Frames}
A frame can be added to a branch in the {\em property window} (see
\ref{propwindow}). 
Alternatively, you can use use images as frames. Have a look at the demo
map {\tt todo.vym} as an example, where the mapcenter is a cloud. You
can use an external drawing program like {\tt gimp} to create an image,
preferable with an transparency channel, so that you can design frames
which don't use a rectangular borderline, just like that cloud.


\subsection{Design of map background and connecting links }
The design of the background of a map and also of the links connecting
various parts of the map can be changed by
\begin{itemize}
	\item Selecting Format from the menu
	\item Right clicking on the canvas, which will open a context menu
\end{itemize}

\subsubsection*{Background }
The colour is set (and also displayed) as "Set background colour".
Alternatevily you can set an background image, though this is not
recommended in general. Working on the map becomes slow and the image
currently cannot be positioned freely.

\subsubsection*{Link colour}
Links connecting branches can be coloured in one of two ways:
\begin{itemize}
	\item use the same colour for the heading and for the branch link line.
	\item use {\em one} colour for all links and choose different colours for the branch headings text. The default colour for branch link lines is blue.
\end{itemize}
The latter can be set with "Set link colour". Check or uncheck the "Use
colour of heading for link" option to toggle between the two designs for
your map.

\subsubsection*{Link style}
\vym offers four different styles for the appearences of links:
\begin{itemize}
	\item Line
	\item Parabel
	\item Thick Line
	\item Thick Parabel
\end{itemize}
The "thick" styles only apply to links starting at the mapcenter, link lines for the rest
of the map are always painted "thin".


\subsection{Links to other documents and webpages}
\vym supports two kind of external links:
\begin{itemize}
	\item Document, which will be opened in an external webbrowser
	\item \vym map, which will be opened in \vym itself
\end{itemize}
In addition to the external links there also internal ones, leading from one
branch in a map to another one. Those are called {\em XLinks} and are explained
in section~\ref{xlinks}.

\subsubsection*{Webbrowser}
Modern Webbrowsers like {\tt konqueror and Firefox} are able to display various
types of files, both local or on the internet. To enter the URL of
any document, right-click  onto a branch to open the contextmenu then choose "Edit URL". Enter the path to your document (or copy and paste it from your browser). Examples for valid paths are:
\begin{verbatim}
	http://www.insilmaril.de/vym/index.html
	file:/usr/share/doc/packages/vym/doc/vym.pdf
\end{verbatim}
If an URL was entered, a little globe will appear in the branch. By
clicking on the globe in the toolbar or the context menu an external
browser\footnote{
	The browser can be changed in the Settings Menu.}
will be launched.
\begin{center}
	\includegraphics[width=0.5cm]{images/flag-url.png}
\end{center}
For more information on working with bookmarks and webbrowsers see
section \ref{bookmarks}.

In the context menu there is also an option to open all URLs found
in the selected subtree of the map. That's useful to simultanously open
a collection of URLs in the webbrowser, especially if the browser can
open them in tabs (like Konqueror).


\subsubsection*{\vym map}
To link to to another map right click on a branch and choose "Edit \vym link". A file dialog opens where you can choose the map. A
branch with a link is marked with 
\begin{center}
	\includegraphics[width=0.5cm]{images/flag-vymlink.png}
\end{center}
Clicking this flag beside the branch heading, in the toolbar or in the context menu of a branch will open the map in another tab (see \ref{tabs} for working with
multiple maps). To delete an existing link, just right click the branch and select "Delete \vym link".

In the context menu there is also an option to open all vymlinks found
in the selected subtree of the map. That's useful to simultanously open
a collection of related maps.

Technical note: Internally \vym uses absolute paths, to avoid opening
several tabs containing the same map. When a map is saved, this path is
converted to a relative one (e.g. {\tt /home/user/vym.map} might become
{\tt ./vym.map}. This makes it fairly easy to use multiple maps on
different computers or export them to HTML in future.

\subsection{Multiple maps} \label{tabs}
You can work on multiple maps at the same time. Each new map is opened
in another {\em tab}. The available tabs are shown just above the
mapeditor. You can use the normal cut/copy/paste functions to
copy data from one map to another.

\section{Noteeditor} \label {noteeditor}
If you want to attach more text to a branch e.g. a complete email, a
cooking recipe, or the whole source code of a software project, you can
use the noteeditor. 
	\maximage{images/noteeditor.png}
This editor displays text associated with a branch selected in the mapeditor. The noteeditor
shows different background colours depending on whether text is associated with a selected branch.

\subsection{States}
Before you can type or paste text into it, you have
to select a branch in the mapeditor. Note that the background colour
of the noteeditor indicates its state:
\begin{itemize}
	\item grey: no text entered yet
	\item white: some text has been entered
\end{itemize}	
In the mapeditor itself, to signal that there is a note with more
information for a particular branch, a little "note" flag will appear next
to the heading of the branch. This is illustrated in the lower branch on the right hand side:
	\maximage{images/branches-flags.png}

\subsection{Import and export notes}
The note is always saved automatically within the \vym map itself.
Nevertheless sometimes it is nice to import a note from an external file
or write it. In the Note Editor use "File\ra~Import" and "File\ra~Export" to do so. 

\subsection{Edit and print note}
Editing works like in any simple texteditor, including undo and redo
functions. You can delete the complete note by clicking the
trashcan. Only the note itself is printed by clicking the printer icon.

\subsection{RichText: Colours, paragraphs and formatted text}
\vym supports formatted text (QT Rich Text) in the noteeditor since
version 1.4.7.  Colours and text attributes (e.g. italic, bold) can be
set with the buttons above the text.  The text itself is divided into
paragraphs. For each paragraph the format can be set (e.g. centered,
right). A paragraph is ended when a \key{Return} is entered. If you just
want to begin a new line, press \key{CTRL-Return}.

\subsection{Fonts and how to switch them quickly}
The noteeditor is designed to be used for simple notes, not really as a full
featured word processor. Because of many requests \vym supports 
formatted text in the noteeditor\footnote{
	\vym uses the QRichtText format, which is basically a subset of the
	formatting provided in HTML.}
Two default fonts are supported which can be set in the Settings menu.
One is a fixed width font, the other has variable width. The fixed font
is usually used for emails, source code etc.\ while the variable font is
used for simple notes, where one doesn't need fixed character widths.
Both fonts can easily switched using the following symbol from the
toolbar:
\begin{center}
	\includegraphics[width=0.5cm]{images/formatfixedfont.png}
\end{center}
In the Settings menu both fonts can be set. The default font can also be toggled between the fixed and variable font by selecting or deselecting the "fixed font is default" menu item.

Additionally to the default fonts any font installed on your system can
be used. Please note, that the chosen font also will be used for HTML
exports, so if youy VYM mind map could ever be exported to a web or intranet page you should only use fonts which are available generally.

\subsection{Find text}
The noteeditor itself has no Find function, use Find in the mapeditor,
which will also search all notes (see \ref{findwindow}).

\subsection{Paste text into note editor}
Often you will paste text into the editor from another application e.g.
an email. Normally \vym will generate a new paragraph for each new line.
This usually is not what you want, so you can choose from the menu


\section{Hello world}
This section is about how \vym can interact with other applications.
Many applications can now read and write their data using XML, the
eXtensible Markup Language. \vym also uses XML to save its maps, see
\ref{fileformat} for a more detailed description. 

So if you make use of another application that understands XML, chances are good that someone
could write import/export filters for \vym. Volunteers are always
welcome ;-)

\subsection{Import} \label{import}

\subsubsection*{KDE Bookmarks}
The integrated bookmark editor in KDE (Konqueror etc.) is somewhat limited, so why not
use \vym to maintain the bookmark mess? To create a new map containing
your current KDE bookmarks just choose
\begin{itemize}
	\item File \ra Import\ra KDE Bookmarks
\end{itemize}

\subsubsection*{Mind Manager}
\vym has currently a very basic import filter to convert maps created by
{\em Mind Manager}\footnote{Mind Manager is a commercial i.e. non free, software application by Mindjet for Windows and the Mac. Both names are registered trademarks by Mindjet. For more information see their website at
\href{http://mindjet.com}{http://mindjet.com}} into \vym maps. Notes and
pictures are not converted at the moment. You can import files with
\begin{itemize}
	\item File \ra Import\ra Mind Manager
\end{itemize}


\subsubsection*{Directory structure}
\vym can read a directory structure. This is mainly for
testing \vym e.g. to easily create huge maps used for benchmarks (yes,
there is still room to optimize \vym ;-)




\subsection{Export}  \label{export}
\label{hideexport}
Often you may not want to export the whole map, but just parts of it. For
example you may have additional info you want to talk about in a
presentation, while those parts should not be visible to the audience.
To achieve this you can "hide" parts of the map during exports by
setting the "hide in export" flag.
\begin{center}
	\includegraphics[width=0.5cm]{images/flag-hideexport.png}
\end{center}
You can toggle this flag in the toolbar or by pressing \key{H}.
Note that there is a global option in the settings menu to toggle the
use of this flag. By default the flag is enabled.

\subsubsection*{Open Office}
Open Office beginning with version~2 uses the so called "Open Document Format", which can be written by \vym. The options are
currently limited, but it possible to export presentations which can be
opened in Open Office Impress. By selecting
\begin{itemize}
	\item File  \ra Export\ra Open Office
\end{itemize}
you get a file dialogue where you can choose the output file and the
file type:
	\maximage{images/export-oo.png}
The file types represent various templates, which can be created with
some manual work from an existing Open Office document. The structure of
\vym map is then inserted into a template. 
There are some limitations at the moment:
\begin{itemize}
	\item \vym can't take care of page lengths, so you have to check and
	probably reedit in Open Office to avoid text running over the end of
	a page
	\item Images and flags are not used at the moment
	\item Notes are just written as plain text, without RichText 
	\item The full range of templates are not available in all distributions.	
\end{itemize}
Some of the templates make use of {\em sections} i.e sections insert the
headings of mainbranches as chapters for sections into the presentation.

\subsubsection*{Image}
\vym supports all image formats which are natively supported by the
QT~toolkit:
BMP, JPEG, PBM, PGM, PNG, PPN, XPM, and XBM.
For use in websites and for sending images by email PNG is a good
recommodation regarding quality and size of the image. \vym uses QTs
default options for compressing the images.

\subsubsection*{ASCII}
Exporting an image as text is somewhat experimental at the moment. Later
this will probably be done using stylesheets. So the output may change in
future versions of \vym.

\subsubsection*{\LaTeX}
\vym can generate an input file for \LaTeX. Currently this is considered
as experimental, there are no options (yet). 
By selecting
\begin{itemize}
	\item File  \ra Export\ra \LaTeX 
\end{itemize}
you will be asked in a file dialog for the name of the output file. This
file may then be included in a \LaTeX document using command: 
\begin{verbatim}
	\include{inputfile.tex}
\end{verbatim}

\subsubsection*{KDE Bookmarks}
\vym will overwrite the KDE bookmarks file and then try to notify
running Konquerors via DCOP of the changed file. \vym does not create a
backup!
\begin{itemize}
	\item File \ra Export \ra KDE Bookmarks
\end{itemize}


\subsubsection*{XHTML (Webpages)}

This is the format to use if you wish to create a webpage. To see an example
visit the \vym homepage: 
\href{http://www.InSilmaril.de/vym}{www.InSilmaril.de/vym}

Some explanation on how this works: 
Before a map is exported as XHTML, it will be first written as XML into a
directory (see \ref{xmlexport}). Then the external program {\tt
xsltproc}\footnote{On SUSE Linux and some other distributions {\tt xsltproc} is installed by
default.}
will be called to process the XML file and generate HTML code.
A dialog allows the user to set various options:
\begin{itemize}
	\item {\bf Include image:} If set, \vym will creat an image map at
	the top of the HTML output. Clicking on a branch in the map will
	jump to the corresponding section in the output.

	\item {\bf Colored headings:}
	If set to yes, \vym will colour the headings in the text part  with the
	same colours used in the \vym map.
	\item {\bf Show Warnings:}
	If set to yes, \vym will ask before overwriting data.
	\item {\bf Show output:}
	This is useful mainly for debugging. It will show how the processing of
	the XML file works by calling the external {\tt xsltproc}.
\end{itemize}
Additionally the paths to the CSS and XSL stylesheets can be set. By
default on SUSE~Linux they will be in {\tt /usr/share/vym/styles}.


\subsubsection*{XML} \label{xmlexport}
The map is written into a directory both as an image and as an XML file. The
directory is set in a file dialog. If the directory is not empty, you
will be warned and offered choices if you are at risk of overwriting existing contents.

It is possible to export different maps into the same directory. Each
file generated will have the map's name as prefix, e.g. {\tt todo.vym}
becomes {\tt todo.xml}, {\tt todo.png}, {\tt todo-image-1.png} and so
on. This is useful if, for example, a website comprises several combined maps that have to be stored in the same directory.

\subsubsection*{Export a part of a map}
Select a branch you want to export together with its children, then open
the context menu and choose {\em Save Selection}. This will create a
file with the suffix {\tt .vyp}, which is an abbreviation for \lq vym
part\rq.


\section{Advanced Editing}

\subsection{Properties of an object} 
For any branch you can open a satellite window (see \ref{satellite}):
the {\em property window}:
\begin{center}
	\includegraphics[width=8cm]{images/propwindow.png}
	\label{propwindow}
\end{center}
%FIXME create screenshot
%FIXME explain the tabs

\begin{itemize}
	\item Frame
	\item Link (see \ref{hideunselected})
	\item Layout (see \ref{incimg})
\end{itemize}

\subsection{Changing the history: Undo and Redo}
\vym keeps track of all changes done in a map. The default number of
changes which can be undone is~75. The complete history can be seen in
the {\em historywindow}:
	\maximage{images/historywindow.png}
	\label{historywindow}
A single step back be undone or redone with \key{CTRL-Z} or \key{CTRL-Y},
or by using the buttons in the toolbar or the {\em historywindow}.
Inside the {\em historywindow}, you can click on a line to unwind all
actions done until that point in time -- or redo all changes by clicking
on the last line.

\hint{
	You can "paste from the past": Go back in time by e.g. with
	\key{CTRL-Z}, then copy to clipboard by pressing \key{CTRL-C}.

	Now do all actions again, e.g. by \key{CTRL-Y} or clicking on the
	last action in {\em historywindow}. Now paste from the past with
	\key{CTRL-V}.
}

\subsection{Macros} \label{macros}
Macros have been added to \vym in version~1.9.0. Each function key
\key{F1} to \key{F12} holds a macro, which is executed on the current
selection if the key is pressed. The default macros change the colour of
a subtree or set the frame of a branch:
\begin{center}
	\includegraphics[width=8cm]{images/macros.png}
\end{center}
Each macro is a \vym script, which is executed when the associated key
is pressed. The default location of the scripts can be changed in the
Settings menu. More information on using scripts in \vym is found in
appendix~\ref{scripts}.

\subsection{Bookmarks} \label{bookmarks}
\subsubsection*{Open new tabs instead of new windows}
If you use konqueror as your browser, \vym will remember the konqueror session which
was opened first by \vym. You can also press \key{Ctrl} and click to
open the link in a new tab.

\vym can also open a new tab in Mozilla or Firefox using the remote
command\footnote{\href{http://www.mozilla.org/unix/remote.html}{http://www.mozilla.org/unix/remote.html}}
of these browsers.

\subsubsection*{Drag and Drop}
If you want to keep bookmarks in a map, select a branch where you want
to add the bookmark, then simply drag the URL from your browser to the
map. Also you could use an existing heading as URL: Right click onto the
branch and select "Use heading for URL".


\subsubsection*{Directly access bookmark lists of a browser}
Please see the sections \ref{import} and \ref{export} about
Import and Export filters.

\subsubsection*{Special URLs}
\vym can turn an existing heading of a branch into an URL. Currently
this works for Bugentries in the Novell Bugtracking system: Open the
context menu of a branch (usually by right-clicking it) and select
\begin{itemize}
	\item Create URL to Bugzilla
\end{itemize}
The URL will be build from the number in the heading.

\subsection{Associating images with a branch} \label{incimg}
The default setting for an image is for it to float "freely". Images can be
positioned anywhere on the canvas, but may end up in the same place as other
parts of the map obscuring that part of the map.

The solution is to insert or include them "into" a branch. This can be done via
the property window (see \ref{propwindow}):
\begin{itemize}
	\item Include images horizontally
	\item Include images vertically
\end{itemize}
The image is still positioned relative to its parent branch, but the
heading and border of the branch frame adapt to the floating image, see below: 
	\maximage{images/includeImages.png}

\subsection{Modifier Modes} 
Modifiers are for example the \key{Shift}- the \key{Ctrl}- ot the \key{Alt}-keys. When
pressed while applying mouse actions, they will cause \vym to use
a "modified" version of the action which usually would be done. 

%\key{Ctrl} or \key{Alt}is pressed while releasing the branch, it will be
%added above/below the target, not as child of the target.

Without a modifier key pressed, the first mouse click on a branch just selects
it. For the behaviour of the \key{Ctrl} modifier there are several
options, which can be set from the modifier toolbar:
\begin{center}
	\includegraphics[width=3cm]{images/modmodes.png}
\end{center}
The default mode is to copy the colour from the clicked branch to the already
selected branch. The figure above shows the toolbar with the default modifier 
selected. The second modifier
let's you easily copy a whole branch with a single click. The third
modifier lets you create links between branches called {\em xLinks}.
They will be explained in the next section \ref{xlinks}.

\subsection{Hide links of unselected objects} \label{hidelink}
Sometimes it would be useful to position a branch freely, just like a
mainbranch or an image. This is possible for all
branches, you can use a mainbranch and hide its connecting link to the
mapcenter or hide the link between a child branch and its parent. This can be used e.g. for legends or a collection of vymLinks
pointing to other maps:
\begin{center}
	\includegraphics[width=9cm]{images/hiddenlink.png}
\end{center}
To hide the link between a branch and its parent open the
\ref{propwindow} and check "Hide link if object is not selected" on
"Link" tab.


\subsection{XLinks} \label{xlinks}
So far all the data in the \vym map has been treelike. Using xLinks you
can link one branch to any other, just like attaching a rope between two
branches in a real tree. This is especially useful in complex maps,
where you want to have crossreferences which can not be displayed on the same
visible area of the {\em mapeditor} window. The following example map still fits on one screen, but shows how data can be crosslinked. In the graphics there is a link from a task (prepare a presentation) to general information:
	\maximage{images/xlink.png}
Note that a xLink which points to a branch that is not visible (because
it is scrolled), is just shown as a little horizontal arrow. In the
screenshot above have a look at the \lq Tuesday\rq\ branch.

\subsubsection*{Create a xLink}
Choose the link mode from the modifier toolbar (by clicking the toolbar icon or pressing
\key{L}). Select the branch, where the xLink should start. Press the
modifier key \key{Ctrl} and then click on the selected branch where the
link should start and drag the mouse pointer to the branch where the link is to end. (The link is drawn to follow the mouse pointer). When you release the mouse over a branch the xLink becomes permanent.

\subsubsection*{Modify or delete a xLink}
First select a branch at either end of the xLink. Then open the context
menu and select \lq Edit xLink\rq. A submenu contains all the xLinks of
the branch (if there are any). They are named like the branches, where
they end. Choose one and the xLink dialogue opens, where you can set
colour, width and also delete the xLink.

\subsubsection*{Follow a xLink}
In a complex \vym map it sometimes comes in handy to be able to jump to the other end
of a xLink. You can do this by opening the context menu of the branch
and clicking on \lq Goto xLink\rq and selecting the xLink you want to
follow.



\subsection{Adding and removing branches}
The context menu of a branch shows some more ways to add and delete data
e.g. you can delete a branch while keeping its children. The children become
linked to the parent of the previously removed branch.
Similar branches can be inserted into existing maps. For keyboard
shortcuts also have a look at the context menu.

\subsection{Adding a whole map or a part of a map}
Select a branch where you want to add a previously saved map ({\tt
.vym})or a part of a map ({\tt .vyp}) , then open the context menu and
choose {\em Add \ra Add Map (Insert)}. For the import you can choose
between {\em Add Map (Insert)} and {\em Add Map (Replace)}: The imported
data will be added after the selected branch.

\section{\vym on Mac OS X}
\subsection{Overview}
Basically there are two ways to run \vym on Macs:
\subsubsection*{QT Mac Edition:}
	\vym here provides the well known Mac look and feel.  \vym is
	available as zipped Mac OS X application. It has been compiled and
	tested in Mac~OS~10.4. It is using the Mac version of Trolltechs QT library.  
\subsubsection*{X11}
	\vym can also be run using the Linux version, but then menus and
	handling will also be those of the Linux version e.g. The menu bar
	will look different. 

\subsection	{Contextmenu and special keys}
Most Macs unfortunatly just have a single mouse button. In order to show
the context menu which usually would be opened with the right mouse
button, you can click while pressing the \key{kommand}-key.

Especially on Laptops some of the keys usually used on PC keyboards seem
to be missing. The QT-Mac Edition of \vym has its own keyboard
shortcuts. To find the shortcuts just have a look at all the menu
entries, the shortcut is visible next to an entry. Toolbar buttons also
may have shortcuts, just position the mouse pointer over a button and
wait for the little help window to appear. 

\subsection {Viewing external links}
\vym on Mac uses the system call {\tt /usr/bin/open} to view links.
Mac~OS determines automatically if the link is a pdf or www page and
opens the right browser.


\begin{appendix}

\section{\vym initialisation process and configuration}
\subsection{Configuration file}
On startup \vym will look for a configuration for user specific settings
like window positions, toolbars etc. If this file does not already
exist, it will be created. The file is located in the users home
directory. The exact position depends on the platform:
\begin{center}
\begin{tabular}{cl}
	{\bf Platform}	& {\bf Configuration file} \\ \hline
	Linux		& {\tt $\sim$/.config/InSilmaril/vym.conf  } \\
	Mac OS X	& {\tt /Users/NAME/Library/Preferences/com.insilmaril.vym.plist  } \\
\end{tabular}
\end{center}
The file can be edited manually, or on Mac~OS~X with Property List
Editor (installed with xtools).

\subsection{Path to ressources}
\vym will try to find its ressources (images, stylesheets, filters,
etc.) in the following places:
\begin{enumerate}
	\item Path given by the environment variable {\tt VYMHOME}.
	\item If called with the local option (see \ref{options} below),
	      \vym will look for its data in the current directory.
	\item {\tt /usr/share/vym}
	\item {\tt /usr/local/share/vym}
\end{enumerate}

\subsection{Command line options} \label{options}
\vym has the following options:
\begin{center}
\begin{tabular}{cccp{8cm}}\\ 
\bf Option	& \bf Comment & \bf Argument & \bf Description \\ \hline
v & version &			& Show version and codename of \vym\\
l & local	&			& Use local paths to stylesheets, translations, icons, 
                          etc. instead of system paths. Useful for testing\\
h & help	&			& Show help\\
r & run 	& filename	& Run script\\
q & quit	&			& Quit immediatly after startup. Useful for benchmarks.\\
\end{tabular}
\end{center}
You can also give several filenames at the commandline to let \vym open
several maps at once.

\section{Contributing to \vym}
So far I'd say I have written 98\% of the code on my own. No surprise,
that \vym exactly fits my own needs. Nevertheless I would like to
encourage all users of  \vym to contribute. Maybe not only with feature
requests, but also with code, new import/export filters, translations
etc. In this appendix I'll try to show how easy it is to expand the
things you can do already with \vym. I really look forward to hear from
you!

\subsection{Getting help}

\subsubsection*{Frequently asked questions}
Please refer to the FAQ available on the \vym website:
\begin{center}
\href{http://www.InSilmaril.de/vym/faq.html}{http://www.InSilmaril.de/vym/faq.html}
\end{center}

\subsubsection*{Mailinglists}
There are two mailinglists: {\tt vym-forum} is the \vym users forum to
discuss various questions, while {\tt vym-devel} is intended for people
interested in contributing to \vym. You can view the archives and
subscribe at
\begin{center}
\href{https://sourceforge.net/mail/?group_id=127802}{https://sourceforge.net/mail/?group\_id=127802}
\end{center}

\subsubsection*{Contacting the author}\label{author}
Especially for support questions please try the mailinglists first. If
everything else fails you can contact the author Uwe Drechsel at
\begin{center}
\href{mailto:vym@InSilmaril.de}{vym@InSilmaril.de}
\end{center}



\subsection{How to report bugs}
Though Sourceforge has its own bugreporting system, I'd rather prefer if
you contact me directly (see \ref{author}) or even better: You can file
a bugreport in Bugzilla, the bugtracking system of openSUSE:
\begin{center}
\href{http://en.opensuse.org/Submit_a_bug}{http://en.opensuse.org/Submit\_a\_bug}
\end{center}
I build \vym regulary for openSUSE, so you may report it against a
recent version there, even if you  use another Operating System.
Please don't forget to tell me what you are using:
\begin{itemize}
	\item the exact steps needed to reproduce the bug
	\item the version and build date of \vym (see the Help \ra About
	\vym)
	\item hardware and Operating System
\end{itemize}

\subsection{Compiling from the sources}
\subsubsection{Getting the sources} \label{getsources}
You find the latest version of \vym at the project site:
\begin{center}
\href{https://sourceforge.net/projects/vym/}{https://sourceforge.net/projects/vym/}
\end{center}
There you can check them out of the source repository (CVS):\\

\begin{verbatim}
cvs -d:pserver:anonymous@cvs.sf.net:/cvsroot/vym checkout code
\end{verbatim}

\subsubsection{The Qt toolkit}
Qt is C++ toolkit for multiplatform GUI and application development. It
provides single-source portability across MS~Windows, Mac~OS~X, Linux
and all major commercial Unix variants. Qt is also available for
embedded devices. Qt is a Trolltech product. For more information see 
\begin{center}
\href{http://www.trolltech.com/qt/}{www.trolltech.com/qt} 
\end{center}


\subsubsection{Compiling \vym }
Make sure you have installed your Qt environment properly, see the Qt
documentation for details. You need to have the Qt command {\tt qmake}
in your {\tt PATH}-environment, then run
\begin{verbatim}
qmake
make  
make install
\end{verbatim}
The last command {\tt make install} needs root-permissions. Of course it
may be omitted, if you just want to test \vym.

%\subsubsection*{Compiling \vym on Macs}
%FIXME

\subsection{\vym file format} \label{fileformat}
\vym maps usually have the suffix "{\tt .vym}" and represent a
compressed archive of data. If you want to have a
closer look into the data structure map called "mapname.vym", 
just uncompress the map manually using
\begin{verbatim}
	unzip mapname.vym
\end{verbatim}
This will create directories named {\tt images} and {\tt flags} in your
current directory and also the map itself, usually named {\tt
mapname.xml}.
The XML structure of \vym is pretty self explaining, just have a look at
{\tt mapname.xml}.

This XML file can be loaded directly into \vym, it does not have to be
compressed. If you want to compress all the data yourself, use
\begin{verbatim}
	zip -r mapname.vym .
\end{verbatim}
to compress all data in your current directory.

\subsection{New features}
There are lots of features which might find their way into \vym.
Together with \vym you should have received a directory with several
maps e.g. on SUSE~LINUX this is
\begin{center}
	{\tt /usr/share/doc/packages/vym/demos}
\end{center}
where you find the map {\tt todo.vym}. It lists quite a lot of things to
be done in future. If you have more ideas, contact the development team
at
{\tt vym-devel@lists.sourceforge.net}.


\subsection{New languages support}
In order to add a new language to \vym you need 
the sources (see \ref{getsources}) and
an installation of Trolltechs QT. A part of QT are the development
tools, from those tools especially the translation tool "Linguist" is
needed. 

In some Linux distributions the development tools are in an extra package, e.g. on SUSE LINUX you should have installed:
\begin{verbatim}
    qt3-devel.rpm
    qt3-devel-doc.rpm
    qt3-devel-tools.rpm
    qt3-man.rpm
\end{verbatim}
If you don't have QT in your system, you can get it from 
	\href{http://www.trolltech.com}{http://www.trolltech.com} Once you
	are able to compile vym yourself, you can translate the text in vym
	itself by performing the following steps:
\begin{itemize}
	\item Let's assume now your encoding is "NEW" instead of for example
	"de" for german or "en" for english
	
	\item Copy the file {\tt lang/vym\_en.ts} to l{\tt ang/vym\_NEW.ts} (The code
	itself contains the english version.)
		
	\item Add {\tt lang/vym\_NEW.ts} to the TRANSLATIONS section of vym.pro

	\item Run Linguist on {\tt vym\_NEW.ts} and do the translation

	\item Run {\tt lrelease} to create {\tt vym\_NEW.qm}

	\item Do a make install to install the new vym and check your translation
\end{itemize}

If you feel brave, you can also translate the manual. It is written in
LaTeX, you just have to change the file tex/vym.tex. (Linguist and QT
are not needed, but it is useful to know how to work with LaTeX and esp.
pdflatex to create the PDF.) 

Please mail me every translation you have done. I can also give you a
developer access to the project, if you want to provide translations
regulary.  

\subsection{New export/import filters}
\vym supports various kinds of filters. Data can be written directly,
inserted into templates or it can be written as XML data and then
processed by XSL transformations. 

Most of the import/export functionality is available in the classes
ImportBase and ExportBase and subclasses. All of them can be found in
{\tt imports.h} and {\tt exports.h}.

\subsubsection*{Direct import/export}
An example for a direct export is the XML export. This method touches
the implementation of nearly every object of \vym, so whenever possible
you should better use a XSL transformation instead.

If you still want to know how it is done, start looking at 
{\tt MapEditor::saveToDir} in {\tt mapeditor.cpp}.

\subsubsection*{Templates}
Templates have been introduced to export to opendoc format used e.g. by
Open~Office. While I read the spec ($>$ 500 pages) about the format\footnote{
\href{http://www.oasis-open.org/}{http://www.oasis-open.org/}}\ 
I had the feeling that I did not want to write the export from scratch. 
It would be too complex to adapt the styles to your own wishes, e.g. the
layout.

Instead I analyzed existing Open~Office documents. I found out that
there are lots of redundant bits of information in a standard
presentation, for example each list item is contained in its own list.
In the end I came up with the default presentation style, which still
could be simplified, just in case you have free time\ldots

The existing templates are still work in progress, before you spend too
much time developing your own style, please contact me.  Basically the
following steps are needed to build your own style:
\begin{enumerate}
	\item Create an example in Open Office. Use a title, authors name,
	page heading etc.\ which you can easily grep for in the output file.
	
	\item Unzip  the Open Office document into a directory.

	\item The main file is called {\tt content.xml}. All data is in one
	single line. You can split the XML tags using the script {\tt
	scripts/niceXML}, which is part of the \vym distribution.

	\item Copy the output of {\tt niceXML} to {\tt
	content-template.xml}.

	\item Looking closer you will find lots of unused definitions, for
	example of styles. You can delete or simply ignore them.

	\item Try to find your title, authors name. \vym will replace the
	following strings while exporting:
	\begin{center}
	\begin{tabular}{lp{4cm}}
		{\tt <!-- INSERT TITLE -->}		& title of map \\
		{\tt <!-- INSERT AUTHOR-->	}	& author \\
		{\tt <!-- INSERT COMMENT -->}	& comment \\
		{\tt <!-- INSERT PAGES-->}		& content of map \\
	\end{tabular}
	\end{center}
	The content itself is generated in a similar way by inserting lists
	into {\tt page-template}. Here the following substitutions are made:
	\begin{center}

\subsubsection*{XSL Transformation}
\vym uses XSL transformations while exporting (e.g. XHTML) and importing
data (e.g. KDE bookmarks). There is a little code needed to provide the
GUI, the rest is done using the {\tt .xsl} stylesheet and calling the
{\tt xsltproc} processor, which is part of libxslt, the XSLT
C  library  for  GNOME.
