As a newbie to GEF I've struggeld to find a good incremental tutorial that
actually works!. While
reading past posts on a technique I though I needed to use I came across the
"direct edit tutorial/examples?"
thread. Andreas suggested a site which to the dismay of the poster was in
Japenese!. However I would
strongly suggest newbies work through these examples;
http://www13.plala.or.jp/observe/GEF/GEF1.zip
through
http://www13.plala.or.jp/observe/GEF/GEF11.zip
The code has Japanese comments, however the incremental nature of the
tutorial I think will be a great
help to those of us who are feeling a bit overwhelmed!. Below I outline the
increments, as I see them. I
think the changes are so small us newbies can figure out the need for the
code changes without the
comments. Note, all examples are based on the MVC model :)
Example1: Static editor, displaying "Hello World" in a viewer.
Example 2: Replace the string with 3 static boxes
Example 3: Allow boxes to be moved with undo/redo (getting exciting!)
Example 4: Addition of a palette
Example 5: Allow Direct Edit (Oh so that's what it is:)) [ hint: try
clicking _slowly_ on a 'hello world' box]
Example 6: Add 2 connection line types to the palette
Example7: Add a properties view (Window->Show View->Properties)
Example8: Moving a marquee (multi box selection)
Example 9: Addition of File Move on Palette (no idea yet what this does)
Example 10: Add Zoom to the toolbar
Example 11: Add a context viewer that includes a mini view of the entire
edit page with scrolling (very cool)
FYI for each example I added the following imports to plugin.xml (they are
probably a superset of what's required)
<import plugin="org.eclipse.core.runtime.compatibility"/>
<import plugin="org.eclipse.ui.ide"/>
<import plugin="org.eclipse.ui.views"/>
<import plugin="org.eclipse.jface.text"/>
<import plugin="org.eclipse.ui.workbench.texteditor"/>
<import plugin="org.eclipse.ui.editors"/>
Regards,
Andy
