PanAction

Object Hierarchy:

Description:

Content:

Properties:

• public double acceleration_factor { get; set; }
  The initial acceleration factor
• public double deceleration { get; set; }
  The rate at which the interpolated panning will decelerate in
• public bool interpolate { get; set; }
  Whether interpolated events emission is enabled.
• public PanAxis pan_axis { get; set; }
  Constraints the panning action to the specified axis

Creation methods:

• public PanAction ()
  Creates a new PanAction instance

Methods:

• public double get_acceleration_factor ()
  Retrieves the initial acceleration factor for interpolated pan events.
• public float get_constrained_motion_delta (uint point, out float delta_x, out float delta_y)
  Retrieves the delta, in stage space, dependent on the current state of the PanAction, and respecting the constraint specified by the pan_axis property.
• public double get_deceleration ()
  Retrieves the deceleration rate of interpolated pan events.
• public bool get_interpolate ()
  Checks if the action should emit pan events even after releasing the pointer during a panning gesture, to emulate some kind of kinetic inertia.
• public void get_interpolated_coords (out float interpolated_x, out float interpolated_y)
  Retrieves the coordinates, in stage space, of the latest interpolated event, analogous to get_motion_coords.
• public float get_interpolated_delta (out float delta_x, out float delta_y)
  Retrieves the delta, in stage space, since the latest interpolated event, analogous to get_motion_delta.
• public void get_motion_coords (uint point, out float motion_x, out float motion_y)
  Retrieves the coordinates, in stage space, dependent on the current state of the PanAction.
• public float get_motion_delta (uint point, out float delta_x, out float delta_y)
  Retrieves the delta, in stage space, dependent on the current state of the PanAction.
• public PanAxis get_pan_axis ()
  Retrieves the axis constraint set by set_pan_axis
• public void set_acceleration_factor (double factor)
  Factor applied to the momentum velocity at the time of releasing the pointer when generating interpolated pan events.
• public void set_deceleration (double rate)
  Sets the deceleration rate of the interpolated pan events generated after a pan gesture.
• public void set_interpolate (bool should_interpolate)
  Sets whether the action should emit interpolated pan events after the drag has ended, to emulate the gesture kinetic inertia.
• public void set_pan_axis (PanAxis axis)
  Restricts the panning action to a specific axis

Signals:

• public virtual signal bool pan (Actor actor, bool is_interpolated)
  The pan signal is emitted to keep track of the motion during a pan gesture.
• public virtual signal void pan_stopped (Actor actor)
  The pan_stopped signal is emitted at the end of the interpolation phase of the pan action, only when interpolate is set to true.
