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:
----------------------------------------------------------
hacksign@XSign [16:51:41] : ~/Code/XSTest
>> make
gcc XScreenWidth.c -lX11 -o test
hacksign@XSign [16:51:41] : ~/Code/XSTest
>> ./test
Screen Width:4480 Screen Height:1440
Screen count:1
hacksign@XSign [16:51:43] : ~/Code/XSTest
>> cat XScreenWidth.c
#include <X11/Xlib.h>
#include <stdio.h>
int main(int argc, char** argv){
const char* dp_name = ":0.0";
Display* dp = XOpenDisplay(dp_name);
int screen_num = DefaultScreen(dp);
Screen* pScreen = ScreenOfDisplay(dp, screen_num);
printf("Screen Width:%d\tScreen Height:%d\n", pScreen->width,
pScreen->height);
int screen_count = ScreenCount(dp);
printf("Screen count:%d\n", screen_count);
XCloseDisplay(dp);
return 0;
}
----------------------------------------------------------
and the xrandr output:
----------------------------------------------------------
hacksign@XSign [16:51:47] : ~/Code/XSTest
>> xrandr

----------------------------------------------------------
I just got the monitor0's width + monitor1's width.
How can I get something like this :
monitor[0].width = 2560
monitor[1].width = 1920 ?
