[SOLVED] Get screen resolution.

Hi,

Is any way to get the current screen resolution? (not window resolution)

I've searching on docs and i've not found any info.

Hi Raul,

There are no such methods available in API. For a simple case it may look like this (https://stackoverflow.com/a/50205813):

#if WIN32
  #include <windows.h>
#else
  #include <X11/Xlib.h>
#endif

//...

void getScreenResolution(int &width, int &height) {
#if WIN32
    width  = (int) GetSystemMetrics(SM_CXSCREEN);
    height = (int) GetSystemMetrics(SM_CYSCREEN);
#else
    Display* disp = XOpenDisplay(NULL);
    Screen*  scrn = DefaultScreenOfDisplay(disp);
    width  = scrn->width;
    height = scrn->height;
#endif
}

int main() {
    int width, height;
    getScreenResolution(width, height);
    printf("Screen resolution: %dx%d\n", width, height);
}
