I'm currently thinking of adding a GUI to ZEngine [http://zengine.sourceforge.net] a 2D OpenGL Ortho Engine.
If anybody would like to help out on this open source project I'd really appreciate it, some of what I saw here was really great 8).

Game GUIs
cozman: Email me if you''re interested in my GUI (Ready4Dis@aol.com), or catch me online, AIM = CrazyGuy4Eva, MSN = Ready4Dis_1@hotmail.com. I''d be glad to let you use my code, and help you get it working with your project (with all the necessary objects and stuff).

I''ve got a simple design from some framework. It''s alot like the Java GUI system because I like having layouts and other things. It''s also easy for me to visualize and design how things will be.
Sakky, sorry it took so long to reply, didn''t check back on the thread.
Basicly, here''s how things work. I use a main window (on the left) as my parent. All other windows are children.
I have an event listener in my windows update, so when the user clicks the mouse, i send the location and which mouse button was pressed to my main window update function.
the basics of that function, is that we pass the same data to all our children (since children exist above parents) if we get a return value from one of the children (clicked a child window) then we exit out. If not, we check to see if the user clicked on any of my buttons, text boxes, panels, etc etc etc. here''s the code for just the event update section. If you would like more, send me an e-mail.
