Well, I think the combo box is fine. I just want the colors during the
normal display, not while editing the value.

I already tried to change the renderer with     

SetCellRenderer(row,col,new wxGridCellStringRenderer());

Because I just want the colors in the normal grid display. But that
didn't show any effect. Do I really have to completly program my own
editor and renderer for this?
