| Name | Description | |
|---|---|---|
![]() | TouchEventArgs(TouchDevice, Int32) | Initializes a new instance of the TouchEventArgs class. |
| Name | Description | |
|---|---|---|
![]() | Device | Gets the input device that initiated this event.(Inherited from InputEventArgs.) |
![]() | Handled | Gets or sets a value that indicates the present state of the event handling for a routed event as it travels the route. (Inherited from RoutedEventArgs.) |
![]() | OriginalSource | Gets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class.(Inherited from RoutedEventArgs.) |
![]() | RoutedEvent | Gets or sets the RoutedEvent associated with this RoutedEventArgs instance. (Inherited from RoutedEventArgs.) |
![]() | Source | Gets or sets a reference to the object that raised the event. (Inherited from RoutedEventArgs.) |
![]() | Timestamp | Gets the time when this event occurred. (Inherited from InputEventArgs.) |
![]() | TouchDevice | Gets the touch that generated the event. |
| Name | Description | |
|---|---|---|
![]() | Equals(Object) | Determines whether the specified object is equal to the current object.(Inherited from Object.) |
![]() | Finalize() | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.) |
![]() | GetHashCode() | Serves as the default hash function. (Inherited from Object.) |
![]() | GetIntermediateTouchPoints(IInputElement) | Returns all touch points that were collected between the most recent and previous touch events. |
![]() | GetTouchPoint(IInputElement) | Returns the current position of the touch device relative to the specified element. |
![]() | GetType() | |
![]() | InvokeEventHandler(Delegate, Object) | Invokes event handlers in a type-specific way, which can increase event system efficiency.(Overrides InputEventArgs.InvokeEventHandler(Delegate, Object).) |
![]() | MemberwiseClone() | |
![]() | OnSetSource(Object) | When overridden in a derived class, provides a notification callback entry point whenever the value of the Source property of an instance changes.(Inherited from RoutedEventArgs.) |
![]() | ToString() | Returns a string that represents the current object.(Inherited from Object.) |
The following events use TouchEventArgs.
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.
