How to: Make an Object Follow the Mouse Pointer
This example shows how to change the dimensions of an object when the mouse pointer moves on the screen.
The example includes an [!INCLUDETLA#tla_xaml] file that creates the [!INCLUDETLA#tla_ui] and a code-behind file that creates the event handler.
Example
The following XAML creates the [!INCLUDETLA2#tla_ui], which consists of an xref:System.Windows.Shapes.Ellipse inside of a xref:System.Windows.Controls.StackPanel, and attaches the event handler for the xref:System.Windows.UIElement.MouseMove event.
[!code-xamlmouseMoveWithPointer#MouseMoveWithPointerXAML]
The following code behind creates the xref:System.Windows.UIElement.MouseMove event handler. When the mouse pointer moves, the height and the width of the xref:System.Windows.Shapes.Ellipse are increased and decreased.
