GtkComboBox look and feel

[Andreas Volz <lists brachttal net>]

Hi,

I created a GtkComboBox with Glade and it looks like on this image:

The combo is editable, but it shouldn't. It should look like on this
image:

Both are the same gtk-theme and same gtk version. So how could I change
to behaviour and look of this widget. Should I perhaps use another
treeview with a label instead of an Entry? Is there an example for this?

regards
Andreas
