Thanks for the reply. I found a way to fix this but I'm sure it's not ideal=
.

The problem is in treelistctrl.cpp's wxTreeListMainWindow::RefreshSubtree()
method.

If I replace the GetVirtualSize() call with GetClientSize(), it works. For
some
reason, GetClientSize() says the virtual window's height is ~32 instead of
(say) 300.

For my code, I've just done this for now:

 int cw =3D 0;
int ch =3D 0;
#ifdef __WXGTK__
GetClientSize( &cw, &ch );
#else
GetVirtualSize( &cw, &ch );
#endif

Since I don't understand why GetVirtualSize() isn't working, I won't
consider this
a real fix but just a workaround.

Thanks,

carl
