[news.eclipse.tools.gef] outiline view

[sidus68@xxxxxxxxx (Sidney Lee)]

hi! I am working on a graphical editor where each form contains one or 
more panels, and each panel contains controls (label, text fields, 
checkboxes, etc.). I have an outline view which displays the hierarchy, 
for example:

-  panel1
|   |
|    --- group1
|   |   |
|   |    --- label 1
|   |
|    --- lable2
|
+  panel2

because the panels may overlap, I would like to only show the currently 
selected panel in the editor, i.e. when a panel or control is selected in 
the outline view, hide all other panels in the editor. So, my tree edit 
parts implement the ISelectionChangedListener interface and I assume I 
would need to register the edit parts with the ContentOutlinePage as a 
ISelectionProvider? If so, how do I access my graphical editor subclass 
(which contains the ContentOutlinePage subclass) from my tree edit part to 
add it as a listener?

kind regards.
