Simply because it doesn't work, it generates BadDrawable X error.
Check out the code below:
<code>
/* test.c
* gcc test.c -o test -g -Wall `pkg-config --cflags --libs gdk-2.0`
*/
#include <gdk/gdk.h>
#include <X11/Xlib.h>
#include <stdio.h>
int main(int argc, char** argv)
{
gdk_init(&argc, &argv);
Display* display = XOpenDisplay(NULL);
if (!display)
return -1;
Drawable xid = XCreatePixmap(display, DefaultRootWindow(display),
20, 20, 24);
GdkPixmap* pixmap =
gdk_pixmap_foreign_new_for_display(gdk_display_get_default(), xid);
printf("Foreign pixmap = %p\n", pixmap);
return 0;
}
</code>
gdk_pixmap_foreign_new_for_display generates BadDrawable.
This example shows what I eventually need.
