Disable expand all tree nodes on asterisk (*) in windows [message #626133]

Hi,
I have a Tree in my application which has potentially thousands upon
thousands of node. I have structured in such a way as to limit the
number of objects created depending on which nodes the user expands
which is all fine. The user would have to expand alot of nodes to cause
performance problems.
However, if the user opens the tree and hits the asterisk (*) key in
windows, this automatically expands the whole tree. I want to block this
from happening if possible. Would anyone know of a way of doing it or
if it is possible at all?

Thanks.

Hi,

There isn't a way to do this. The earliest opportunity an app has to
receive keystroke notifications is with a KeyDown listener, but I've
confirmed on Windows that this comes in after the Tree SetData and/or Expand
events which could have restricted the tree expansion if they knew that '*'
had been pressed. Sorry.
