Properties:

• public Rect drag_area { owned get; set; }
  Constains the dragging action (or in particular, the resulting actor position) to the specified Rect, in parent's coordinates.
• public bool drag_area_set { get; }
  Whether the drag_area property has been set.
• public DragAxis drag_axis { get; set; }
  Constraints the dragging action to the specified axis
• public Actor drag_handle { get; set; }
  The Actor that is effectively being dragged
• public int x_drag_threshold { get; set; }
  The horizontal threshold, in pixels, that the cursor must travel in order to begin a drag action.
• public int y_drag_threshold { get; set; }
  The vertical threshold, in pixels, that the cursor must travel in order to begin a drag action.

Creation methods:

• public DragAction ()
  Creates a new DragAction instance

Methods:

• public bool get_drag_area (out Rect drag_area)
  Retrieves the "drag area" associated with this, that is a Rect that constrains the actor movements, in parents coordinates.
• public DragAxis get_drag_axis ()
  Retrieves the axis constraint set by set_drag_axis
• public unowned Actor get_drag_handle ()
  Retrieves the drag handle set by set_drag_handle
• public void get_drag_threshold (out uint x_threshold, out uint y_threshold)
  Retrieves the values set by set_drag_threshold.
• public void get_motion_coords (out float motion_x, out float motion_y)
  Retrieves the coordinates, in stage space, of the latest motion event during the dragging
• public void get_press_coords (out float press_x, out float press_y)
  Retrieves the coordinates, in stage space, of the press event that started the dragging
• public void set_drag_area (Rect? drag_area)
  Sets drag_area to constrain the dragging of the actor associated with this, so that it position is always within drag_area, expressed in parent's coordinates.
• public void set_drag_axis (DragAxis axis)
  Restricts the dragging action to a specific axis
• public void set_drag_handle (Actor? handle)
  Sets the actor to be used as the drag handle.
• public void set_drag_threshold (int x_threshold, int y_threshold)
  Sets the horizontal and vertical drag thresholds that must be cleared by the pointer before this can begin the dragging.

Signals:

• public virtual signal void drag_begin (Actor actor, float event_x, float event_y, ModifierType modifiers)
  The drag_begin signal is emitted when the DragAction starts the dragging
• public virtual signal void drag_end (Actor actor, float event_x, float event_y, ModifierType modifiers)
  The drag_end signal is emitted at the end of the dragging, when the pointer button's is released
• public virtual signal void drag_motion (Actor actor, float delta_x, float delta_y)
  The drag_motion signal is emitted for each motion event after the drag_begin signal has been emitted.
• public virtual signal bool drag_progress (Actor actor, float delta_x, float delta_y)
  The drag_progress signal is emitted for each motion event after the drag_begin signal has been emitted.
