Thread: GLUT Resizing and Focusing

I was wondering if there is a way with GLUT to make the window non-resizable...My whole program gets messed up when it is resized. If there isn't, I'll probably find some way to change the coordinate system when the window is resized.

Also, I made a program where you click in the OpenGL window, and points are made where you clicked. But when I focus onto another window, and focus back to the GLUT one, all my dots I made are gone. And when I minus out the program, I get an error message, and it tells me to end the task. Any suggestions?

Thanks!

PS
I am using a single buffer!!! I don't think a second one is needed, because no animation is used in my program.

I think you should. If you constantly swap and redraw, you won't have the problem of dots erasing when you change the window's focus.

Sorry I don't know of a way to prevent window resizing (try using the Win API). EDIT: oops sorry that would take away the point of using glut

Use glutSwapBuffers() to swap them, and then use glClearColor() to clear the current one. It's really easy.
