The org.eclipse.swt.widgets.List widget behaves differently on GTK3 than it does on GTK2 and Win32 when an item is deleted and that deleted item is the only selected item.

Given "list" is a org.eclipse.swt.widgets.List and list.getSelectionCount() == 1
and you do:

list.remove(list.getSelectionIndex())

With GTK2 and Win32:
after the removal list.getSelectionCount() == 0 and list.getSelectionIndex() == -1

With GTK3:
after the removal list.getSelectionCount() == 1 and list.getSelectionIndex() is adjacent or the same as it was.

I have tested this with GTK 3.18.2 from Fedora 23.


This change caused a CDT regression, Bug 493070
