Re: [wxCode-users] wxTreeListCtrl 1104

[PGridDev <pgr...@ya...>]

Thanks Asa

Re not using the control: I mean that I don't have much time for it lately... You already mentioned the wxWidgets 2.9 control which has the same name, so you know the alternative :-)

Duly noted for the memory leak, I will investigate, maybe this week-end.

About the scrolling, if I understood you correctly, you want a behavior similar to Windows explorer, where dragging an object abovethe top or under the bottom of the visible part of a tree will trigger scrolling as long as the cursor does not come back in the tree window.
If so it sounds like a good idea, but is going to be some work, so if you don't mind please enter the request in the Feature Tracker (helps me not forget and gives a chance to other users to add comments):

Cheers
