+ * SECTION:gtkgesturesingle
+ * @Short_description: Gesture especialized for mouse/single finger input
+ * @Title: GtkGestureSingle
+ *
+ * #GtkGestureSingle is an especialization of #GtkGesture, optimized (although
+ * not restricted) to dealing with mouse and single touch gestures. Under
+ * interaction, these gestures stick to the first interacting sequence, which
+ * is accessible through gtk_gesture_single_get_current_sequence() while the
+ * gesture is being interacted with.
+ *
+ * By default gestures only react to touch events, gtk_gesture_single_set_touch_only()
+ * can be used to change this default behavior. Callers may also specify
+ * a mouse button number to interact with through gtk_gesture_single_set_button().
