@param c The connection
@param owner_events If 1, the \a grab_window will still get the pointer events. If 0, events are not
reported to the \a grab_window.
@param grab_window Specifies the window on which the pointer should be grabbed.
@param modifiers The modifiers to grab.
\n
Using the special value XCB_MOD_MASK_ANY means grab the pointer with all
possible modifier combinations.
@param key The keycode of the key to grab.
\n
The special value XCB_GRAB_ANY means grab any key.
@param pointer_mode A bitmask of #xcb_grab_mode_t values.
@param pointer_mode \n
@param keyboard_mode A bitmask of #xcb_grab_mode_t values.
@param keyboard_mode \n
@return A cookie
Establishes a passive grab on the keyboard. In the future, the keyboard is
actively grabbed (as for GrabKeyboard), the last-keyboard-grab time is set to
the time at which the key was pressed (as transmitted in the KeyPress event),
and the KeyPress event is reported if all of the following conditions are true:
The keyboard is not grabbed and the specified key (which can itself be a
modifier key) is logically pressed when the specified modifier keys are
logically down, and no other modifier keys are logically down.
Either the grab_window is an ancestor of (or is) the focus window, or the
grab_window is a descendant of the focus window and contains the pointer.
A passive grab on the same key combination does not exist on any ancestor of
grab_window.
The interpretation of the remaining arguments is as for XGrabKeyboard. The active grab is terminated
automatically when the logical state of the keyboard has the specified key released (independent of the
logical state of the modifier keys), at which point a KeyRelease event is reported to the grabbing window.
Note that the logical state of a device (as seen by client applications) may lag the physical state if
device event processing is frozen.
A modifiers argument of AnyModifier is equivalent to issuing the request for all possible modifier combinations (including the combination of no modifiers). It is not required that all modifiers specified
have currently assigned KeyCodes. A keycode argument of AnyKey is equivalent to issuing the request for
all possible KeyCodes. Otherwise, the specified keycode must be in the range specified by min_keycode
and max_keycode in the connection setup, or a BadValue error results.
If some other client has issued a XGrabKey with the same key combination on the same window, a BadAccess
error results. When using AnyModifier or AnyKey, the request fails completely, and a BadAccess error
results (no grabs are established) if there is a conflicting grab for any combination.
