My monitor configuration is listed at the end of this email post.
My problem:
can not get each monitor's width & height widh xlib.
here is my code:
"monitor" = "output" != "screen" in X11 - nevertheless you're looking for
XRRScreenSize *XRRSizes(Display *dpy,
int screen, int *nsizes);
Pass it the values you have and a reference to "int nsizes" and get back a list
of
typedef struct {
int width, height;
int mwidth, mheight;
} XRRScreenSize;
don't forget to free that.
See http://linux.die.net/man/3/xrrscreenconfig
Notice that this only works as expected w/ the xrandr extension available.
Otherwise you'll (afair) always have one screen with the combined size of the
root window.
Cheers,
Thomas
