ComboBox question

["Christian Schaubschlaeger" <cs gup jku at>]

Hello List!

I'm using a Gtk::ComboBox which has a ListStore as it's
TreeModel. The ListStore holds a number of quite long strings.
When the ComboBox is rendered (in collapsed state), it is
expanded to the length of the longest string in the ListStore.

Is it possible to limit the horizontal size of a ComboBox in
(when it is collapsed) to a certain length?

On the other hand, when the ComboBox pops up, the strings shall
be displayed in the full length.

Thanks and best regards
Christian
