Hello,
I'm considering to use Agar for GUI on top of my SDL/OpenGL
application. I've been playing around with it for couple of days and
it looks neat overly but I exeprienced some quirks.
Below is a minimal code example that compiles on windows with VC 2008.
The problem is that menu sub-item doesn't show up when I click on the
main menu item. However, the same menu setup works as intended when
using default event loop via AG_EventLoop() and without any SDL or GL
code.
I'm not sure I'm doing everything right as there are no code examples
for the case of custom loop with GL+SDL
If anybody has had experience with this, please shed some light.
Thanks,
Nenad
