Description Michal Nikodim

2012-06-21 01:59:32 EDT

use case:
http://rap.eclipsesource.com/rapdemo/examples#treeviewer


1. select "Hong Kong" in left tree  (fired event SWT.Selection)
2. collapse "Asia"
3. expand "Asia"

Row with "Hong Kong" is not selected. When I ask programatically tree.getSelection() then I get "Hong Kong" but visual says "nothing selected".

Bug: after expand tree row, client side have to revisualise selected rows.

Just tested with SWT Tree:
- when multi selection is set on the Tree, collapsing of an item removes the selection from its children. 
- when single selection is set on the Tree, collapsing of an item moves the selection from the child (hidden) item to its visible parent item.

Fixed in master with commit 3dd62ca0e851464f718f15f673d6b3ea0c7f4646.

Could you please reopen the bug?

The problem still exists in 2.1.1 and 2.1.0. See the rap demo. You can reproduce it the same way as stated in Commen #1.

Hi Markus, for me the Examples Demo behaves exactly as described in comment#2. The TreeViewer in the Examples Demo is created with MULTI style flag and selection is removed from the non visible items. Tree#getSelection() returns empty selection as expected.

Never mind, Ivan. Actually we expected that if you expand the item again the selection will still exist. But we checked with SWT and it is the same behavior. So everthing is fine.
