+ * @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.
