I have a gtk program with a GtkWindow. Now I want to get the address to the current display, cause I want to use the function

Code: (Plaintext)
1 2 3 4	XF86VidModeGetModeLine(Display display, int screen, int dotclock_return, XF86VidModeModeLine *modeline);

To get the current modeline. The dotclock_return and modline variables are set by the function and does not have to be preset.

I have looked at this page and tried to find out which function to use, but every function seems to be connected to some kind of object and I don't know how to get those objects. Isn't it just possible to get a pointer to the current display that is viewing right at the moment or the display that the window is in? I also want to get the number of the screen to be able to call the function properly.

Hello TriKri!

This code should get the display of your GTK-Window:

Code: (C)
1 2 3 4 5 6 7	#include <gdk/gdk.h> #include <gdk/gdkx.h> ... GdkWindow gdk_window = nameofyourgtkwindow->window; Display display = GDK_WINDOW_XDISPLAY (gdk_window);

Make sure that your window is visible before executing this code.

Greetings

PS: not 100% sure about the includes ...
