How to know if the mouse is offscreen?

[Djent]

I'm making a dinky paint program where the paint color cycles through the rainbow, and I was wondering if there was any way to know if the user's mouse has left the window. It isn't in the best interest of the program to have a square of color cycling at the edge of my window, and I'd like to pause the color cycle when the mouse leaves the window. love.mouse.getX/Y only go to the length of the window. It would be nice if they returned nil if the mouse was offscreen, but oh well. Is there any way to get around this?

Also, to clarify, I'm not talking about the window being unfocused.

Thanks

Maybe you can try to get X, Y and if X or Y is less than 0 or more than love.graphics.getWidth/Height() then it's offset. I hadn't tried but maybe this works. Or you can try X,Y equal to 0, or equal to love.graphics.getWidth/getHeight() (-1). The second will work.

Does it have something to do with focus lost?
I saw that the mouse never returns values outside of the screen.

Or for a simpler solution, but maybe less comfortable for the end-user:

love.mouse.setGrab( true )
