| 409 | * %GDK_POINTER_MOTION_HINT_MASK, fewer %GDK_MOTION_NOTIFY events will |
| 410 | * be sent, some of which are marked as a hint (the is_hint member is |
| 411 | * %TRUE). To receive more motion events after a motion hint event, |
| 412 | * the application needs to asks for more, by calling |
| 413 | * gdk_event_request_motions(). |
| 414 | * |
| 415 | * Since GTK 3.8, motion events are already compressed by default, independent |
| 416 | * of this mechanism. This compression can be disabled with |
| 417 | * gdk_window_set_event_compression(). See the documentation of that function |
| 418 | * for details. |
| 419 | * |
| 420 | * If %GDK_TOUCH_MASK is enabled, the window will receive touch events |
| 421 | * from touch-enabled devices. Those will come as sequences of #GdkEventTouch |
| 422 | * with type %GDK_TOUCH_UPDATE, enclosed by two events with |
| 423 | * type %GDK_TOUCH_BEGIN and %GDK_TOUCH_END (or %GDK_TOUCH_CANCEL). |
| 424 | * gdk_event_get_event_sequence() returns the event sequence for these |
| 425 | * events, so different sequences may be distinguished. |
