Hello,
I have been trying to get Example 1 from
http://eclipsewiki.editme.com/GefExamples running.
1. I extract the source code and import it as a Project into eclipse.
When I start it ("Run Eclipse Application") this is what I see in the log:
.....
Called GefHelloEditor() constructor
Unhandled event loop exception
Reason:
loader constraints violated when linking org/eclipse/ui/IEditorPart class
2. Then, I created a new project, and manually added all JAR
dependencies and files from the example to it.
Now it starts, and I can open a file with the given extension in the new
eclipse instance, but the display area remains clean white.
Reading the code, I think I should see some rectangles in different
colors. Should I ?
I am using Eclipse 3.1.2 with GEF 3.1.1 on windows.
Thanks,
Tivadar

OK, I figured it out.
In HelloEditPart.createFigure() when it creates the rectange, it creates
a size (0,0) rectangle which is not shown.
Fix:
....
protected IFigure createFigure()
{
System.out.println("Called HelloEditPart.createFigure()");
RectangleFigure rectangle = new RectangleFigure();
>>>>> rectangle.setSize(20,20); <<<<<<<<<<<<< add this line
....
no doubt, it was an educative example...
