Hi there,
I'm trying to draw large scenes on multi monitor setups. I can get all
screens and the resolutions of the screens via:
numberOfScreens = XScreenCount(dpy);
/* Work out the sizes of the screens */
for (int j = 0; j<numberOfScreens; j++)
{
Screen *screen = XScreenOfDisplay(dpy, j);
SIZE_X = DisplayWidth(dpy,j);
SIZE_Y = DisplayHeight(dpy, j);
printf("Width::%d\tHeight::%d\n", DisplayWidth(dpy,j),
DisplayHeight(dpy,j));
}
But how can I get where one screen is in relation to another?
eg. If there are four(4) 2560x1600 monitors arranged in a column, the top
screen has its first pixel at [0,0], the second monitor is [0, 1600], third is
[0,3200], etc
This is ok to dodgy hack, but when I move to a machine where the monitors are
arranged horizontally
eg [0,0], [2560,0], [5120, 0] and [7680,0]
All breaks. I would prefer not to have a configuration file and would also
prefer not to parse the xorg.conf file.
PS. I have have temporarily confused the [0,0] pixel with opengl (bottom left -
as opposed to top left for a screen. Hopefully you still get the idea).
Any pointers? It appears as though xdotool appears to know this information
when moving a mouse.
Cheers
Mark
