Remarks
A Holding event is sent whenever a finger, pen, or similar pointing device is pressed and held on an object.
Once a short time threshold has elapsed, the event is sent with a HoldingState of type Started.
When the device has been lifted (after a Holding event), another Holding event is sent with a HoldingState of type Completed.
If the user cancels the hold after it has been started, but before it completes, a Holding event is sent with a HoldingState of type Canceled.
Constructors
HoldingRoutedEventArgs() |
Initializes a new instance of the HoldingRoutedEventArgs class. |
Properties
Handled |
Gets or sets a value that marks the routed event as handled. A |
HoldingState |
Gets the underlying HoldingState for the interaction. |
OriginalSource |
Gets a reference to the object that raised the event. This is often a template part of a control rather than an element that was declared in your app UI. (Inherited from RoutedEventArgs) |
PointerDeviceType |
Gets the PointerDeviceType for the pointer device that initiated the associated input event. |
Methods
GetPosition(UIElement) |
Returns the x- and y-coordinates of the pointer position, optionally evaluated against a coordinate origin of a supplied UIElement. |
