Dualhead fullscreen and mouse disappears

SDL Development
1

Hello!

I have application that does opengl graphics with SDL, and has control-gui
with wxwindows …

The sdl window is on it’s own head (display), and control-gui on it’s own.

Now, If I set up the sdl window fullscreen, I lose the mouse pointer
totally… it disappears. I can’t use it in the other head (where I have the
control-gui)…

Any way to solve this? I’m using Linux / XFree86.

Thanks!

hey Pasi,

One way is you can get the position of the mouse and draw your own cursor at
those coordinates (:> ----- Original Message -----

Sorry, This doesn’t work. The mouse heads off the the bottom right of
the SDL surface and sits there. I’m sticking to looking at the SDL
surface in a window in my dual head setup. If you find a solution let us
know.

Hmm… so it’s not possible to use other head when other is in fullscreen
with SDL ?

Is there some real reason for this… maybe I should check the sources…

There is. It’s a matter of sharing input between the two heads.

See ya,
