<br><font size=2 face="sans-serif">I have a JFace treeviewer which displays
data from my model. The user can right click to delete a node from the
tree. The handler removes the item from the model and fires a document
changed event to which the content outline page is listening. The tree
then refreshes and the item dissapears. The treeviewer can also be filtered.
The tree also displays logical and physical layouts so the same object
may appear in the tree twice.</font>
<br>
<br><font size=2 face="sans-serif">All I want to do is to change the selection
to the item after the one that is being deleted.</font>
<br>
<br><font size=2 face="sans-serif">At the moment the selection seems to
change back to the physical parent on refresh even if the selectd item
was in the logical layout. When deleting items from an element with many
screens of children you have to keep scrolling back down to get to the
next item to delete. Because a deleted item may cause orphan items in my
structure I also clean the model on deletion so I can only handle a single
deletion at a time.</font>
<br>
<br><font size=2 face="sans-serif">Any ideas how I can find the next visible
item in the tree after the selected one.</font>
