GDI animation...

Hi there!
I want to develop a small freeware card game in wxWindows.
1. Can I use GDI animation? Will it be smooth and fast enough - given that I am going to store the game window in a bitmap and blt it to screen? I am not looking for killer performance. But cards moving, being dragged etc. One thing I noted was that wxWidgets does not have anything like QueryPerformanceCounter in Windows.
Any existing app which has used GDI animation using wxWindows?
2. wxList. I am planning to use this extensively for AI(which uses selective simulation). How fast is it??
regards and thanks,
Vipin

Sure you can

Check the "forty" demo. It's a bit old but maybe this gives you an idea of how to do things (WXDIR\demos\forty). It's a card game.

True. Things like that are not easy to be ported throughout all platforms. An easy way for Windows & Linux is using ASM. Get the tick count with CPUID, wait a sec and get the tick again. On a Mac this won't work...

wxList. I am planning to use this extensively for AI(which uses selective simulation). How fast is it??

Good question. Can't comment on that one except that using it is pretty stable.
