	/**
	 * 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 is done because most
	 * applications expect to receive paired press and release events.
	 *
	 * 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.
	 *
	 * Params:
	 *     window = the #GdkWindow which will own the grab
	 *     capabilities = capabilities that will be grabbed
	 *     ownerEvents = if %FALSE then all device events are reported with respect to
	 *         @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 = 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 = the event that is triggering the grab, or %NULL if none
	 *         is available.
	 *     prepareFunc = function to
	 *         prepare the window to be grabbed, it can be %NULL if @window is
	 *         visible before this call.
	 *     prepareFuncData = user data to pass to @prepare_func
	 *
	 * Returns: %GDK_GRAB_SUCCESS if the grab was successful.
