Class PanGesture

Definition

Namespace:

Tizen.NUI

Assembly:

Tizen.NUI.dll

A PanGesture is emitted when the user moves one or more fingers in a particular direction.
A pan gesture will end in the following ways:

• User releases the primary finger (the first touch).
  
• User has more fingers on the screen than the maximum specified.
  
• User has less fingers on the screen than the minimum specified.
  
• Cancelled by the system.
  A pan gesture will continue to be sent to the actor under than initial pan until it ends.

Constructors

PanGesture()

The default constructor.

Declaration

public PanGesture()

Properties

Displacement

This is a Vector2 showing how much the user has panned (dragged) since the last pan gesture or, if the gesture has just started, then the amount panned since the user touched the screen.
A positive x value shows that the user is panning to the right, a negative x value means the opposite.
A positive y value shows that the user is panning downwards, a negative y value means upwards.

Declaration

public Vector2 Displacement { get; }

Property Value

Type	Description
Vector2

NumberOfTouches

The total number of fingers touching the screen in a pan gesture.

Declaration

public uint NumberOfTouches { get; }

Property Value

Type	Description
uint

Position

The current touch position of the primary touch point in local actor coordinates.

Declaration

public Vector2 Position { get; }

Property Value

Type	Description
Vector2

ScreenDisplacement

This is a Vector2 showing how much the user has panned (dragged) since the last pan gesture or, if the gesture has just started, then the amount panned since the user touched the screen.
A positive x value shows that the user is panning to the right, a negative x value means the opposite.
A positive y value shows that the user is panning downwards, a negative y value means upwards.
This value is in screen coordinates.

Declaration

public Vector2 ScreenDisplacement { get; }

Property Value

Type	Description
Vector2

ScreenPosition

The current touch position of the primary touch point in screen coordinates.

Declaration

public Vector2 ScreenPosition { get; }

Property Value

Type	Description
Vector2

ScreenVelocity

The velocity at which the user is moving their fingers.
This is represented as a Vector2 and is the pixel movement per millisecond.
A positive x value shows that the user is panning to the right, a negative x value means the opposite.
A positive y value shows that the user is panning downwards, a negative y values means upwards.
This value represents the screen coordinates.

Declaration

public Vector2 ScreenVelocity { get; }

Property Value

Type	Description
Vector2

Velocity

The velocity at which the user is moving their fingers.
This is represented as a Vector2 and is the pixel movement per millisecond.
A positive x value shows that the user is panning to the right, a negative x value means the opposite.
A positive y value shows that the user is panning downwards, a negative y values means upwards.

Declaration

public Vector2 Velocity { get; }

Property Value

Type	Description
Vector2

Methods

GetDistance()

Returns the distance the user has panned (dragged) since the last pan gesture or, if the gesture has just started, then the distance moved since the user touched the screen.
This is always a positive value.

Declaration

public float GetDistance()

Returns

Type	Description
float	The distance, as a float, a user's finger has panned.

GetScreenDistance()

Returns the distance the user has panned (dragged) since the last pan gesture in screen coordinates or, if the gesture has just started, then the distance in screen coordinates moved since the user touched the screen.
This is always a positive value.

Declaration

public float GetScreenDistance()

Returns

Type	Description
float	The distance, as a float, a user's finger has panned.

GetScreenSpeed()

Returns the speed at which the user is moving their fingers relative to screen coordinates.
This is the pixel movement per millisecond.

Declaration

public float GetScreenSpeed()

Returns

Type	Description
float	The speed of the pan (in pixels per millisecond).

GetSpeed()

Returns the speed at which the user is moving their fingers.
This is the pixel movement per millisecond.

Declaration

public float GetSpeed()

Returns

Type	Description
float	The speed of the pan (in pixels per millisecond).
