How to limit the number of rows in a GtkComboBox ?

["Melinda Chin" <melinda cacmedia tv>]

Hi, I would like to limit the number of rows listed in the drop
down/drop up list.

 

For example, if I want to list only 5 entries at a time,
and there are currently 11, I would like to show 5 
when the drop down/drop up list is activated.
I would also like to have a scroll bar in order to scroll down to view
the next 5 entries.

 

Is there a way to do this ?

 

I have tried gtk_combo_box_set_row_span_column, but it doesn't seem to
do what I want.

 

Thanks.
