I've been having issues with CustomTreeCtrl leaving behind ghosted controls in my application that supports Copying/Pasting nodes.
If I copy a bunch of nodes in the middle of my tree and paste the copies...the controls on the tree nodes that got pushed down (such as a wxTextCtrl) sometimes seem to stay where they were (effectively covering the newly pasted nodes). It doesn't appear to be a purely visible ghost, because I can click in the text boxes and edit them.
that third image is poorly named - thats after a collapse/expand of the "feature" node, not after a Refresh in the code.
Has anyone else noticed this behavior with CustomTreeCtrl? Is it just something I'm doing wrong in the code? Or is it a bug? I've tried using RefreshSubTree and passing it the parent node of the level that I'm doing copying on - that did not help. I've also tried using Freeze/Thaw before/after I paste the items - that also did not help. Generally when I collapse/expand the tree - then the controls finally get put into the right place (although not always).
Looking at the Expand method I see a couple other things that might affect the layout of the child widgets. In addition to self.RefreshSubtree(item) it calls self.CalculatePositions() and self.HideWindows(). Have you tried those?

calling HideWindows() on the tree seemed to do the trick. Sometimes it leaves 1 control behind for a second or two, but it is certainly much better than before.
Thanks,
