I'd like to intercept the WM_DELETE_WINDOW message that is posted to a certain selection of windows that an application I'm writing ( AllTray ), so that I can act on it instead of the application receiving it. I'm currently looking at trying this at the GDK level via gdk_display_add_client_message_filter if possible, but I'd be happy with an Xlib solution if there is one as well; it seems to be possible, but I just don't seem to be understanding how I am to do it successfully. Currently, I have two programs (written in C) that I am trying to use to get this figured out, the first one does

I have been trying to implement Win32's MessageBox using GTK. The app using SDL/OpenGL, so this isn't a GTK app. I handle the initialisation ( gtk_init ) sort of stuff inside the MessageBox function as follows: int MessageBox(HWND hwnd, const char* text, const char* caption, UINT type) { GtkWidget *window = NULL; GtkWidget *dialog = NULL; gtk_init(&gtkArgc, &gtkArgv); window = gtk_window_new(GTK_WINDOW_TOPLEVEL); g_signal_connect(G_OBJECT(window), "delete_event", G_CALLBACK(delete_event), NULL); g_signal_connect(G_OBJECT(window), "destroy", G_CALLBACK(destroy), NULL); // gcallback calls gtk

What functions would one use to take a screenshot of an X11 desktop, using the Xlib library? I would prefer a method that's more efficient than getting individual pixels. Thanks. The standard tool for taking screenshots in X11 is to use xwd -root > myscreen.xwd Then, convert to .pnm with xwd2pnm myscreen.xwd > myscreen.pnm Therefore, you can locate the source code of xwd and see how it is implemented, http://cvsweb.xfree86.org/cvsweb/xc/programs/xwd/xwd.c?rev=HEAD&content-type=text/vnd.viewcvs-markup 来源： https://stackoverflow.com/questions/5293525/screenshots-in-x11

I want to do some Python scripting on my server where I can communicate with finch (A console interface of pidgin , with the interface looking like links2 ) through the DBus Python library to send messages or check for buddy online status. This works if you do it in X. Run finch in an X terminal and run the Python script in another terminal with no errors/exceptions. But if you do it without X , you have to run finch in TTY1 (ctrl+alt+f1) and the python script in TTY2 (ctrl+alt+f2) but the python script will fail . The following is the first few lines of the script: import dbus bus = dbus

A window should stay on top of all other windows. Is this somehow possible with plain x11/xlib? Googling for "Always on top" and "x11" / "xlib" didn't return anything useful. I'd avoid toolkits like GTK+, if somehow possible. I'm using Ubuntu with gnome desktop. In the window menu, there's an option "Always On Top". Is this provided by the X server or the window manager? If the second is the case, is there a general function that can be called for nearly any wm? Or how to do this in an "X11-generic" way? Edit: I implemented fizzer's answer, now having following code: XSelectInput(this->display

I've tried to create a fully transparent window using C++ & X11. It should not consume any events and simply forwards them to the windows below. Some kind of GlassPane as it's known for Java-Windows, but full screen. Then I'd like to draw on this window. Is this somehow possible with X11? My first attempt was ignoring all events, simply copy the image from the root window using XGetImage() ... But first of all, this is quite slow as the window would need to be full screen. XShmGetImage unfortunately isn't an option here. For sure, this window wouldn't need any decoration, but that isn't a big

I'm trying to run a command with paramiko that should be able to open an X window. The script I'm using would something as follows: import paramiko ssh_client = paramiko.SSHClient() ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh_client.connect('192.168.122.55', username='user', password='password') transport = ssh_client.get_transport() session = transport.open_session() session.request_x11() stdin = session.makefile('wb') stdout = session.makefile('rb') stderr = session.makefile_stderr('rb') session.exec_command('env; xterm') transport.accept() print 'Exit status:',
