/**
* gdk_event_get_state:
* @event: a #GdkEvent or NULL
- * @state: return location for state
+ * @state: (out): return location for state
*
* If the event contains a "state" field, puts that field in @state. Otherwise
* stores an empty state (0). Returns %TRUE if there was a state field
/**
* gdk_event_get_coords:
* @event: a #GdkEvent
- * @x_win: location to put event window x coordinate
- * @y_win: location to put event window y coordinate
+ * @x_win: (out): location to put event window x coordinate
+ * @y_win: (out): location to put event window y coordinate
*
* Extract the event window relative x/y coordinates from an event.
*
/**
* gdk_event_get_root_coords:
* @event: a #GdkEvent
- * @x_root: location to put root window x coordinate
- * @y_root: location to put root window y coordinate
+ * @x_root: (out): location to put root window x coordinate
+ * @y_root: (out): location to put root window y coordinate
*
* Extract the root window relative x/y coordinates from an event.

/**
* gdk_event_get_axis:

- * @axis_use: the axis use to look for
- * @value: location to store the value found
+ * @axis_use: (out): the axis use to look for
+ * @value: (out): location to store the value found
*
* Extract the axis value for a particular axis use from
* an event structure.
* gdk_events_get_center:
* @event1: first #GdkEvent
* @event2: second #GdkEvent
- * @x: return location for the X coordinate of the center
- * @y: return location for the Y coordinate of the center
+ * @x: (out): return location for the X coordinate of the center
+ * @y: (out): return location for the Y coordinate of the center
*
* If both events contain X/Y information, the center of both coordinates
* will be returned in @x and @y.
