Can you prevent TreeView to be collapsed/expanded???
Hi Chris,
(Re: Can you prevent TreeView to be collapsed/expanded???)
I have downloaded and tried it.
may be i am wrong but this sample code doesn't work
properly. After setting some of the 3 check buttons
you can still force the TreeView to be expanded/collapsed.
Just set e.g. the 'Prevent to Expand' toggle box on and try to
expand the selected node by pressing Enter button and left
mouse button (a few times with Keyboard and a few times
with mouse). Then you see that the TreeView is still expanded
but an in a very strange/buggy way.
You can see that the selected item/node can be sometimes
expanded (by changing - to + and some borders which are drawn)
but you are not still to see all childeren.
I think this piece of code is not fully tested.
Cheers,
Nasser
