JScript에서는 클래스에서 정의한 이벤트를 처리할 수 있지만 이벤트를 직접 정의할 수는 없습니다.

XAML 특성 사용

<object MouseMove="MouseEventHandler" .../>

라우팅 이벤트 정보

Identifier field	MouseMoveEvent
Routing strategy	Bubbling
Delegate	MouseEventHandler

The corresponding tunneling event is PreviewMouseMove.
Override OnMouseMove to implement class handling for this event in derived classes.

설명

This event creates an alias for the Mouse.MouseMove attached event for this class, so that MouseMove is part of the class members list when ContentElement is inherited as a base element. Event handlers that are attached to the MouseMove event are attached to the underlying Mouse.MouseMove attached event and receive the same event data instance.

예제

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. For the complete sample, see Moving an Object with the Mouse Pointer Sample.

The following XAML creates the UI, which consists of an Ellipse inside of a StackPanel, and attaches the event handler for the MouseMove event.

XAML

<Window x:Class="WCSamples.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="mouseMoveWithPointer"
    Height="400"
    Width="500"
    >
  <Canvas MouseMove="MouseMoveHandler"
          Background="LemonChiffon">
    <Ellipse Name="ellipse" Fill="LightBlue" 
             Width="100" Height="100"/>
  </Canvas>
</Window>

The following code behind creates the MouseMove event handler. When the mouse pointer moves, the height and the width of the Ellipse are increased and decreased.

// raised when the mouse pointer moves.
// Expands the dimensions of an Ellipse when the mouse moves.
private void MouseMoveHandler(object sender, MouseEventArgs e)
{
    // Get the x and y coordinates of the mouse pointer.
    Point position = e.GetPosition(this);
    double pX = position.X;
    double pY = position.Y;

    // Sets the Height/Width of the circle to the mouse coordinates.
    ellipse.Width = pX;
    ellipse.Height = pY;
}
