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.

The TreeViewer should be the selection provider for the selection service in
the workbench. The editparts are the items which are actually selected.
You can tie the outline and editor together via the selectionservice, which
spans across every part in the workbench window. See
editorsite.getSelectionService.

thanks v. much!
one question though: would an alternative solution - to install an edit
policy for my AbstractTreeEditPart subclass using
EditPolicy.SELECTION_FEEDBACK_ROLE and subclass the SelectionEditPolicy,
where showSelection() and hideSelection() show/hide the the relevant
panels - be feasible too?
