This event creates an alias for the Mouse.MouseMove attached event for this class, so that is part of the class members list when UIElement is inherited as a base element. Event handlers that are attached to the event are attached to the underlying Mouse.MouseMove attached event and receive the same event data instance.
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.
<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 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 Sub OnMouseMoveHandler(ByVal sender As Object, ByVal e As MouseEventArgs) 'Get the x and y coordinates of the mouse pointer. Dim position As System.Windows.Point position = e.GetPosition(Me) Dim pX As Double pX = position.X Dim pY As Double pY = position.Y 'Set the Height and Width of the Ellipse to the mouse coordinates. ellipse1.Height = pY ellipse1.Width = pX End Sub
