HitTestResult Class
Provides the base class for several derived classes that represents the return value from a hit test.
System.Windows.Media.HitTestResult
System.Windows.Media.GeometryHitTestResult
System.Windows.Media.Media3D.RayHitTestResult
System.Windows.Media.PointHitTestResult
Namespace: System.Windows.Media
Assembly: PresentationCore (in PresentationCore.dll)
The HitTestResult type exposes the following members.
| Name | Description | |
|---|---|---|
 | 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.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
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. } }
