TouchEventArgs TouchEventArgs TouchEventArgs TouchEventArgs Class

Definition

Provides data for touch input events.

public ref class TouchEventArgs : System::Windows::Input::InputEventArgs
public class TouchEventArgs : System.Windows.Input.InputEventArgs
type TouchEventArgs = class
    inherit InputEventArgs
Public Class TouchEventArgs
Inherits InputEventArgs
Inheritance

Examples

The following example handles the TouchUp events that occur on a Canvas. It checks the Captured property to verify that the device that raised the event is captured to the Canvas. If it is, the TouchDevice is released.

This example is part of a larger example that is available in the TouchDevice class overview.

private void canvas_TouchUp(object sender, TouchEventArgs e)
{
    Canvas _canvas = (Canvas)sender as Canvas;
    if (_canvas != null && e.TouchDevice.Captured == _canvas)
    {
        _canvas.ReleaseTouchCapture(e.TouchDevice);
    }
}
' Touch Up
Private Sub canvas_TouchUp(ByVal sender As System.Object, ByVal e As System.Windows.Input.TouchEventArgs)
    Dim _canvas As Canvas = CType(sender, Canvas)
    If (_canvas IsNot Nothing AndAlso e.TouchDevice.Captured Is _canvas) Then
        _canvas.ReleaseTouchCapture(e.TouchDevice)

    End If
End Sub

Remarks

The following events use TouchEventArgs.

(Inherited from RoutedEventArgs)
RoutedEvent RoutedEvent RoutedEvent RoutedEvent

Gets or sets the RoutedEvent associated with this RoutedEventArgs instance.

(Inherited from RoutedEventArgs)

Methods

Equals(Object) Equals(Object) Equals(Object) Equals(Object)

Determines whether the specified object is equal to the current object.

(Inherited from Object)

Serves as the default hash function.

(Inherited from Object)
GetIntermediateTouchPoints(IInputElement) GetIntermediateTouchPoints(IInputElement) GetIntermediateTouchPoints(IInputElement) GetIntermediateTouchPoints(IInputElement)

Returns all touch points that were collected between the most recent and previous touch events.

GetTouchPoint(IInputElement) GetTouchPoint(IInputElement) GetTouchPoint(IInputElement) GetTouchPoint(IInputElement)
