I have a user complaining about then insert behavior of
TreeContainerEditPolicy. The problem seems to be when inserting a new
child into a parent list, the parent is selected. For example:
***A*** (* is supposed to show highlighted)
- B
- C
------------------ <-- new insertion point
- D
The problem becomes when the parent is not visible in the window, then the
highlight action causes the tree item to be revealed which then scrolls
the window.
I would like to continue to show target feedback when users are adding new
children (or moving), but it seems that the key methods in
TreeContainerEditPolicy are either final or private preventing me from
overriding any behavior.
Aside from copying the implementation into my subclass, are there any
tricks I can leverage to prevent the highlighting of the parent item?
Thanks,
Erik

Open a bug, and submit a patch, if possible. 3.4 will be out soon. Until
then, you can override showTargetFeedback() and eraseTargetFeedback().
