Combo Box Behaving Like A Huge Menu
Message 1 in thread
My application uses combo boxes extensively, with some of them holding
hundreds of entries. When I run the program on Kubuntu (which is where I do
my development), it runs perfectly. When I copy the compiled binary over to
my Fedora Core system, all the combo boxes act more like cascading menus
rather than having the line input box and a short scrollable list.
For combo boxes with a large number of items, when the drop down arrow is
selected, the entire screen gets filled with menu panels containing the list
data. The current item is then shown with a checkbox next to it wherever
that item happens to reside in the menu panels.
Has anyone encountered this? Is it some kind of Qt configuration option?

It's the style that controls this. Ubuntu is probably using the plastique
style and Fedora is probably using clean looks. The style controls this
using the QStyle::SH_ComboBox_Popup enum.
