glut multiple windows general

[true_atlantis]

when i create 3 windows using glut like this


for(int i=0;i<3;i++){
glutInitWindowSize(300,300);
glutInitWindowPosition(310*i,0);
int x = glutCreateWindow("View");
winid[i]=x;
}it will create the 3 windows... but if i try to select one, by doing


glutSetWindow(winid[0]); it will not work... the only window that can be accessed is the last one created. is there some sort of initialization so there can be more than one window?

Try setting each window after it's created, then set your callbacks. Works fine for me, though I've not really played with it much.

im not sure i understand exactly what you mean... do you mean

for(int i=0;i<3;i++){
glutInitWindowSize(300,300);
glutInitWindowPosition(310*i,0);
int x = glutCreateWindow("View");
winid[i]=x;
glutSetWindow(winid[0]);
}

Pretty much, but you need to supply callbacks for each window you create.


for( int i = 0; i < 3; i++ )
{
glutInitWindowSize(300,300);
glutInitWindowPosition(310*i,0);
glutCreateWindow("View");

glutReshapeFunc( reshape );
glutDisplayFunc( display );
// ...
}
