The mouse motion function is called when a button is pressed and the mouse if moving in the window.

I use both the glutMouseFunc and glutMotionFunc together.

I get what button has been pressed with the glutMouseFunc and then track the mouse with glutMotionFunc.


glutMouseFunc( int Button, int x, int y)
{

if (left_button_down)
{
left_button_state = 1;
}else left_button_state = 0;

}

glutMotionFunc(int x, int y)
{

if(left_button_state) move_object(x,y);

}

note this is just an example code, a little more would need to be added for it to be functional.
