Provides data for the MouseWheel routed event.
Assembly: System.Windows (in System.Windows.dll)
Public NotInheritable Class MouseWheelEventArgs _ Inherits MouseEventArgs
public sealed class MouseWheelEventArgs : MouseEventArgs
The MouseWheelEventArgs type exposes the following members.
|Delta||Gets a value that indicates the amount that the mouse wheel rotated relative to its starting state or to the last occurrence of the event.|
|Handled||Gets or sets a value that marks the routed event as handled, and prevents most handlers along the event route from rehandling the same event.|
|OriginalSource||Gets a reference to the object that raised the event. (Inherited from RoutedEventArgs.)|
|StylusDevice||Gets an object that reports stylus device information, such as the collection of stylus points associated with the input. (Inherited from MouseEventArgs.)|
|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 the Object is reclaimed by garbage collection. (Inherited from Object.)|
|GetHashCode||Serves as a hash function for a particular type. (Inherited from Object.)|
|GetPosition||Returns the x- and y-coordinates of the pointer position, optionally evaluated against a coordinate origin of a supplied UIElement. (Inherited from MouseEventArgs.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
Because MouseWheel is a routed event, it can invoke handlers on objects other than the object that raised the event. MouseWheelEventArgs has a Handled property, which enables marking the event as handled and shortens the event route in all but exceptional handling cases.
