If none is found, the ordinary root - * window is returned, thus retaining backward compatibility with standard - * window managers. - * The function implementing the virtual root lookup remembers the result of - * its last invocation to avoid overhead in the case of repeated calls - * on the same display and screen arguments. - * The lookup code itself is taken from Tom LaStrange's ssetroot program. - * - * Most simple root window changing X programs can be converted to using - * virtual roots by just including - * - * #include - * - * after all the X11 header files. It has been tested on such popular - * X clients as xphoon, xfroot, xloadimage, and xaqua. - * It also works with the core clients xprop, xwininfo, xwd, and editres - * (and is necessary to get those clients working under tvtwm). - * It does NOT work with xsetroot; get the xsetroot replacement included in - * the tvtwm distribution instead. - * - * Andreas Stolcke , 9/7/90 - * - replaced all NULL's with properly cast 0's, 5/6/91 - * - free children list (suggested by Mark Martin ), 5/16/91 - * - include X11/Xlib.h and support RootWindowOfScreen, too 9/17/91 - * - * Jamie Zawinski , 28-Apr-1997 - * - use ANSI C - * - * Jamie Zawinski , 3-Sep-2003 - * - if the environment variable "XSCREENSAVER_WINDOW" is set, use that - * as the root window instead of searching for __SWM_VROOT. - */ - -#ifndef _VROOT_H_ -#define _VROOT_H_ -#define _XSCREENSAVER_VROOT_H_ - -#if !defined(lint) && !defined(SABER) -static const char vroot_rcsid[] = - "#Id: vroot.h,v 1.5 2003/09/04 01:04:38 jwz Exp #" "\n" - "#Id: vroot.h,v 1.4 1991/09/30 19:23:16 stolcke Exp stolcke #"; -#endif - -#include -#include -#include - -static Window -#ifdef __STDC__ /* ANSIfication added by jwz, to avoid superfluous warnings. */ -VirtualRootWindowOfScreen(Screen * screen) -#else /* !__STDC__ */ -VirtualRootWindowOfScreen(screen) -Screen *screen; -#endif /* !__STDC__ */ -{ - static Screen *save_screen = (Screen *) 0; - static Window root = (Window) 0; - - if (screen != save_screen) { - Display *dpy = DisplayOfScreen(screen); - Atom __SWM_VROOT = None; - int i; - Window rootReturn, parentReturn, *children; - unsigned int numChildren; - - /* first check for a hex or decimal window ID in the environment */ - const char *xss_id = getenv("XSCREENSAVER_WINDOW"); - if (xss_id && *xss_id) { - unsigned long id = 0; - char c; - if (1 == sscanf(xss_id, " 0x%lx %c", &id, &c) || - 1 == sscanf(xss_id, " %lu %c", &id, &c)) { - root = (Window) id; - save_screen = screen; - return root; - } - } - - root = RootWindowOfScreen(screen); - - /* go look for a virtual root */ - __SWM_VROOT = XInternAtom(dpy, "__SWM_VROOT", False); - if (XQueryTree(dpy, root, &rootReturn, &parentReturn, &children, &numChildren)) { - for (i = 0; i < numChildren; i++) { - Atom actual_type; - int actual_format; - unsigned long nitems, bytesafter; - Window *newRoot = (Window *) 0; - - if (XGetWindowProperty(dpy, children[i], - __SWM_VROOT, 0, 1, False, XA_WINDOW, - &actual_type, &actual_format, - &nitems, &bytesafter, - (unsigned char **) &newRoot) == Success && newRoot) { - root = *newRoot; - break; - } - } - if (children) - XFree((char *) children); - } - - save_screen = screen; - } - - return root; -} - -#undef RootWindowOfScreen -#define RootWindowOfScreen(s) VirtualRootWindowOfScreen(s) - -#undef RootWindow -#define RootWindow(dpy,screen) VirtualRootWindowOfScreen(ScreenOfDisplay(dpy,screen)) - -#undef DefaultRootWindow -#define DefaultRootWindow(dpy) VirtualRootWindowOfScreen(DefaultScreenOfDisplay(dpy)) - -#endif /* _VROOT_H_ */
