HitTestResult Class
Visual Studio 2008
Provides the base class for several derived classes that represents the return value from a hit test.
Assembly: PresentationCore (in PresentationCore.dll)
The PointHitTestResult, GeometryHitTestResult, and RayHitTestResult classes derive from HitTestResult.
The following example shows how to retrieve the HitTestResult return value from the HitTest method.
// Respond to the left mouse button down event by initiating the hit test. private void OnMouseLeftButtonDown(object sender, MouseButtonEventArgs e) { // Retrieve the coordinate of the mouse position. Point pt = e.GetPosition((UIElement)sender); // Perform the hit test against a given portion of the visual object tree. HitTestResult result = VisualTreeHelper.HitTest(myCanvas, pt); if (result != null) { // Perform action on hit visual object. } }
