How to stop expanding an infinite SWT Tree upon pressing "*"
- by Lóránt Pintér
I have an SWT Tree in my application that contains an infinite data structure. Upon expanding an item, I generate its children. On Windows though, users can press "*", triggering an "expand all descendants" action, and my application hangs.
There are two acceptable behaviors for me when the user presses "*":
Expand all children of the selected element, but only to the next level
Do nothing
In either case, I will still need to be able to expand items as deep as required (by clicking on the [+] icon, or by pressing "+"), so limiting the tree depth is not a solution. Is there another way that I can achieve either of the above without modifying SWT classes?
