Hi All,
While using wxPython 2.2.2 on top of wxWindows/GTK 2.2.2 I encountered
strange focus behaviour in dialogs. It seems that SetFocus() method
has no effect for some child controls. The attached program illustrates
this for dialog containing one instance of wxTextCtrl and one instance
of wxComboBox. The "self.cb1.SetFocus()" line (emphasized by
appropriate comments) has no effect on wxGTK (it works as expected on
Windows). Strangely enough, it works OK for two wxTextCtrls, but not
for two wxComboBoxes.
(Note: you need to click somewhere inside the program main frame
client area for dialog to appear)
