Hi All
I would like to have the same behaviour on FocusEvents in ULCTable and
ULCTableTree.
In my snippet this is not the case...
The ULCTableTree does not get any FocusEvent (Mouse and Tab) even on the
UI side.
What's wrong?
The workaround with the mouseevent does not solve my problem because I
still do not have the FocusLostEvent.
Another workaround with the selectionListener is as well not helpfull
because then I miss the FocusLostEvent also.
I'm using ULC 6.1.
Thanks a lot!
Alex
