Provides data for mouse related routed events that do not specifically involve mouse buttons or the mouse wheel, for example UIElement.MouseMove.
Assembly: PresentationCore (in PresentationCore.dll)
Thetype exposes the following members.
|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.)|
|LeftButton||Gets the current state of the left mouse button.|
|MiddleButton||Gets the current state of the middle mouse button.|
|MouseDevice||Gets the mouse device associated with this event.|
|OriginalSource||Gets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class. (Inherited from RoutedEventArgs.)|
|RightButton||Gets the current state of the right mouse button.|
|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.)|
|StylusDevice||Gets the stylus device associated with this event.|
|Timestamp||Gets the time when this event occurred. (Inherited from InputEventArgs.)|
|XButton1||Gets the current state of the first extended mouse button.|
|XButton2||Gets the state of the second extended mouse button.|
|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 a hash function for a particular type. (Inherited from Object.)|
|GetPosition||Returns the position of the mouse pointer relative to the specified element.|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|InvokeEventHandler||Invokes event handlers in a type-specific way, which can increase event system efficiency. (Overrides InputEventArgs.InvokeEventHandler(Delegate, Object).)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|OnSetSource||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.)|
This event data class is used with the following attached events.
This event data class is used with the following routed events. These routed events forward the previously listed attached events to make them more accessible to the general element model in WPF.
The attached events and the base element routed events share their event data, and the bubbling and tunneling versions of the routed events also share event data. This can affect the handled characteristics of the event as it travels the event route. For details, see Input Overview.
Other than the RoutedEventArgs properties that are relevant for all routed events, the most interesting properties of that you might use in a MouseEventHandler implementation are several properties that expose the current button state (such as LeftButton) and MouseDevice). MouseDevice is useful particularly because you can check Captured on it.
Note that events that specifically deal with mouse button events use a different event data class, MouseButtonEventArgs. The mouse button properties are available on in case there are input modes or interactions that involve the buttons even if you are handling a non-button event.
The Mouse class provides additional properties and methods for determining the state of the mouse.
This example shows how to change the dimensions of an object when the mouse pointer moves on the screen.
The example includes an Extensible Application Markup Language (XAML) file that creates the user interface (UI) and a code-behind file that creates the event handler.
