GtkExpander

[Arne Caspari <arnem informatik uni-bremen de>]

Hi!

I am trying to use a GtkExpander but it does not work as expected. The expander is contained in a hbox which 
by itself is contained in a vbox. 
If I click on the expander, the size request of the hbox is not changed and the child is not displayed 
properly. 

I tried to connect to the "activate" signal to update the size request of the vbox to match the request of 
the expander but it does not work 
as expected: 
gtk_widget_size_request() always gives the size request of the state which is currently NOT selected. Ie. if 
the expander is active and 
the child should be visible, I actually get a smaller size request than if the expander is rolled up and the 
child is hidden.

Has anybody an idea how to correctly embed the expander?
