/**
* PDA Version of FreeMind, based heavily on various SuperWaba example code and
* released under the corresponding LGPL.
*
* @author vik@diamondage.co.nz
*
* TODO:
*
* With able assistance from tester kwoodham:
*
* A POSITION ID in for the nodes attached to the root.
* POSITION="right|left".
*
*Looks like the shorthand method for closing off the node element:
<node TEXT="here's an element"/>
...creates problems when you go back in and assign an icon:
<node TEXT="here's an element"/>
<icon BUILTIN="messagebox_warning"/>
Since the "/" in the node line closes out the node object, the icon won't get
attached to it on when the map is rendered in FreeMind on the PC side. Looks
to me like separate <node> </node> tags need to be generated when the node is
created - that way, if an icon is attached later, its tag will be correctly
inserted between the tags:
<node TEXT="here's an element">
<icon BUILTIN="messagebox_warning"/>
</node>
Would be nice to have a "Sibling" button alongside the child to generate a
new node at the same level. The "Insert" puts the new node right under the
parent. Best way I've found to generate a sibling node is to hit "Child" then
use the arrow to move the node left when I've entered it.
The "extended" entry needs to close when the node is closed out and a new
node entered. Right now, when I edit an extended entry, close, then open a
different node, the extra lines - and the extended text from the previous node
- are still displayed.
