wxComboBox refresh X11 2.8.0

[Jan Boehme]

Hi.

I have a wxComboBox filled with different strings. When the program 
state changes I want to change the selection of the combobox without 
user automatically.

I tried Select(int) and SelectStringSelection( wxString& ) but in the 
X11 port (win and gtk work) the control won't be updated. Internally 
they are set in the right way but the ui refresh doesn't work.

Also calling Refresh() doesn't work here.

Can anyone help me out?

Thanks, Jan.
