ok, here is a minimal test program: --- snip --- // modfied from: // Ch. Tronche (http://tronche.lri.fr:8000/) #include <X11/Xlib.h> #include <assert.h> #include <unistd.h> #define NIL (0) int main() { Display *dpy = XOpenDisplay(NIL); assert(dpy); int blackColor = BlackPixel(dpy, DefaultScreen(dpy)); int whiteColor = WhitePixel(dpy, DefaultScreen(dpy)); // Create the window Window w = XCreateSimpleWindow(dpy, DefaultRootWindow(dpy), 0, 0, 250, 150, 0, blackColor, blackColor); XSelectInput(dpy, w, StructureNotifyMask); XMapWindow(dpy, w); XFlush(dpy); // Wait for the MapNotify event for(;;) { XEvent e; XNextEvent(dpy, &e); if (e.type == MapNotify) break; } Window child = XCreateSimpleWindow(dpy, /*w*/ DefaultRootWindow(dpy) , 0, 0, 200, 100, 0, whiteColor, whiteColor); XSelectInput(dpy, child, StructureNotifyMask); XMapWindow(dpy, child); // Wait for the MapNotify event for(;;) { XEvent e; XNextEvent(dpy, &e); if (e.type == MapNotify) break; } XFlush(dpy); // reparent (to x,y does not work, not processing events) XReparentWindow(dpy, child, w, 0, 0 ); XFlush(dpy); XSync(dpy,true); sleep(100); } --- snip --- reparenting a white window into a black one. This works both locally and over an ssh connection, but not with xpra (no white window in the black one shown). (The crash I was referring to happens when I try to reparent the winIDs from the parentID of the session, giving me different winIDs , which may not be a good idea) Cheers Bodo -- Dr. Bodo Martin University Heidelberg Anorganisch-Chemisches Institut Im Neuenheimer Feld 270 69120 Heidelberg Germany Phone: +49-6221-546610 Fax: +49-6221-546617 Web: http://bodomartin.uni-hd.de _______________________________________________ shifter-users mailing list [email protected] http://lists.devloop.org.uk/mailman/listinfo/shifter-users
