View Full Version : Problem with callback button in GLUI

11-19-2014, 06:17 PM
I am using OpenGL with GLUI for building UI for my application.
I tried to add a button using the GLUI object glui and passed the callback function btnNext() to it.

glui->add_button("Next", 0, (GLUI_Update_CB)btnNext);

And the btnNext() is defined as

void btnNext(){

This is supposed to move the orbiter object(a sphere) by 1 unit.

But this is not working. Nothing happens on the onclick event of the button. Is this definition valid? Is it legal to call glutPostRedisplay() from inside a callback function?
