Behaviour of earlier X servers was to deliver the ButtonPress event unconditionally, regardless of the actual event mask being set. This is documented in the protocol: "This request establishes a passive grab. In the future, the pointer is actively grabbed as described in GrabPointer, the last-pointer-grab time is set to the time at which the button was pressed (as transmitted in the ButtonPress event), and the ButtonPress event is reported if all of the following conditions are true: <list of conditions, event mask is not one of them>" Thus, a GrabButton event will always deliver the button press event, a GrabKey always the key press event, etc. Same goes for XI and XI2. Reproducible with a simple client requesting a button grab in the form of: XGrabButton(dpy, AnyButton, AnyModifier, win, True, ButtonReleaseMask, GrabModeAsync, GrabModeAsync, None, None); On servers before MPX/XI2, the client will receive a button press and release event. On current servers, the client receives only the release. Clients that expect the press event to be delivered unconditionally. XTS Xlib13 XGrabButton 5/39 now passes. This reverts commit |

X Server The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into. Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders. For a comprehensive overview of X Server and X Window System, consult the following article: http://en.wikipedia.org/wiki/X_server All questions regarding this software should be directed at the Xorg mailing list: http://lists.freedesktop.org/mailman/listinfo/xorg Please submit bug reports to the Xorg bugzilla: https://bugs.freedesktop.org/enter_bug.cgi?product=xorg The master development code repository can be found at: git://anongit.freedesktop.org/git/xorg/xserver http://cgit.freedesktop.org/xorg/xserver For patch submission instructions, see: http://www.x.org/wiki/Development/Documentation/SubmittingPatches For more information on the git code manager, see: http://wiki.x.org/wiki/GitPage
