Saving/Associating slider values with a pop-up menu

I'm writing a plugin that's modifying an existing UI. One thing I want to do is change what an existing menu item does. This is all using the Gtk library.

What are some choices to port existing Windows GUI app written in C to Linux?

I've been tasked with porting an existing Windows GUI app to Linux. Ideally, I'd like to do this so the same code base can be used to build either the Windows version or the Linux version.

Programmatically Centering UIViews

Java swing examples - Ants running around a world getting food from piles?

I haven't done any swing programming in a while, so I'm looking for some GUI examples that are at least close to what I'm trying to do.

Once the node (ant...

Let's say I'm a Qt newbie. I want a good Qt library for displaying simple graphs. I've found the quanava library. But there is a problem. When I compiled a basic example it looks like graph edges are not painted properly when moving nodes. I don't have any idea where is a bug but this code seems to be rather simple. I think this is a pro...

What is the point of JComboBox's getSelectedItem()?
