[paragui-users] Eventloop question

[jonas bösch]

Hi, 

another stupid question from my big pile of stupid questions... 

how can i get my application to call a function everytime it runs the 
mainloop..

in glut (what i used before) i just added a 

myClass->liveOneStep(); 

call to the render() function..

how would i do this in ParaGUI / SDL? 

Thanks in advance, 

jonas
