I would like to gather inforamtion about all the
running X applicaiotns.
Thus I do
Window root = RootWindow (dpy, screenno);
XQueryTree (dpy, root, &dummywindow, &dummywindow,
&children, &nchildren);
for (i = 0; i < nchildren; i++) {
if (XGetWindowAttributes(dpy, children[i],
&attr) && (attr.map_state == IsViewable)) {
XFetchName(dpy, children[i], &win_name);
printf("Window ID: 0x%lx\n",children[i]);
}
}
I thought that win_name will contain the name of the
window, but it is always null,
what am I doing wrong?
Thanks!
