Class PanGesture
Definition
- 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
View SourcePanGesture()
The default constructor.
Declaration
public PanGesture()
Properties
View SourceDisplacement
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; }

Vector2 |
NumberOfTouches
The total number of fingers touching the screen in a pan gesture.
Declaration
public uint NumberOfTouches { get; }

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.

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.

View SourceGetDistance()
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. |

This is the pixel movement per millisecond.
Declaration
public float GetScreenSpeed()
Returns
Type | Description |
