* @window and are only reported if selected by @event_mask. If
* %TRUE then pointer events for this application are reported
* as normal, but pointer events outside this application are
* reported with respect to @window and only if selected by
* @event_mask. In either mode, unreported events are discarded.
* @cursor: (nullable): the cursor to display while the grab is active. If
* this is %NULL then the normal cursors are used for
* @window and its descendants, and the cursor for @window is used
* elsewhere.
* @event: (nullable): the event that is triggering the grab, or %NULL if none
* is available.
* @prepare_func: (nullable) (scope call): function to prepare the window to be
* grabbed, it can be %NULL if @window is visible before this call.
* @prepare_func_data: (closure prepare_func): user data to pass to @prepare_func
*
* Grabs the seat so that all events corresponding to the given @capabilities
* are passed to this application until the seat is ungrabbed with gdk_seat_ungrab(),
* or the window becomes hidden. This overrides any previous grab on the
* seat by this client.
*
* As a rule of thumb, if a grab is desired over %GDK_SEAT_CAPABILITY_POINTER,
* all other "pointing" capabilities (eg. %GDK_SEAT_CAPABILITY_TOUCH) should
* be grabbed too, so the user is able to interact with all of those while
* the grab holds, you should thus use %GDK_SEAT_CAPABILITY_ALL_POINTING most
* commonly.
*
* Grabs are used for operations which need complete control over the
* events corresponding to the given capabilities. For example in GTK+ this
* is used for Drag and Drop operations, popup menus and such.
*
* Note that if the event mask of a #GdkWindow has selected both button press
* and button release events, or touch begin and touch end, then a press event
* will cause an automatic grab until the button is released, equivalent to a
* grab on the window with @owner_events set to %TRUE. This performed as most
* applications expect to receive presses and releases in pairs.
*
* If you set up anything at the time you take the grab that needs to be
* cleaned up when the grab ends, you should handle the #GdkEventGrabBroken
* events that are emitted when the grab ends unvoluntarily.
*
* Returns: %GDK_GRAB_SUCCESS if the grab was successful.
*
* Since: 3.20
