Constructors summary

Initializes a new instance of the DoubleTappedRoutedEventArgs class.

Properties summary

Gets or sets a value that marks the routed event as handled. A true value for Handled prevents most handlers along the event route from handling the same event again.

Gets the PointerDeviceType for the pointer device that initiated the associated input event.

Methods summary

Returns the x- and y-coordinates of the pointer position, optionally evaluated against a coordinate origin of a supplied UIElement.

Constructors

Properties

  • Handled
    Handled
    Handled
    Handled

    Gets or sets a value that marks the routed event as handled. A true value for Handled prevents most handlers along the event route from handling the same event again.

    Property Value

    • bool
      bool
      bool

      true to mark the routed event handled. false to leave the routed event unhandled, which permits the event to potentially route further and be acted on by other handlers. The default is false.

  • PointerDeviceType

Methods

  • GetPosition(UIElement)
    GetPosition(UIElement)
    GetPosition(UIElement)
    GetPosition(UIElement)

    Returns the x- and y-coordinates of the pointer position, optionally evaluated against a coordinate origin of a supplied UIElement.

    public Point GetPosition(UIElement relativeTo)public Point GetPosition(UIElement relativeTo)Public Function GetPosition(relativeTo As UIElement) As Pointpublic Point GetPosition(UIElement relativeTo)

    Parameters

    • relativeTo

      Any UIElement -derived object that is connected to the same object tree. To specify the object relative to the overall coordinate system, use a relativeTo value of null.

    Returns

    • A Point that represents the current x- and y-coordinates of the mouse pointer position. If null was passed as relativeTo, this coordinate is for the overall window. If a relativeTo value other than null was passed, this coordinate is relative to the object referenced by relativeTo.
