Specifies a Geometry as the parameter to be used for hit testing a visual tree.
Assembly: PresentationCore (in PresentationCore.dll)
Thetype exposes the following members.
|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 the default hash function. (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.)|
Windows Presentation Foundation (WPF) hit testing only considers the filled area of a geometry during a hit test. If you create a point Geometry, the hit test would not intersect anything because a point has no area.
The following example shows how to set up a hit test using for the HitTest method. The Point value that is passed to the OnMouseDown method is used to create a Geometry object in order to expand the range of the hit test.
The IntersectionDetail property of GeometryHitTestResult provides information about the results of a hit test that uses a Geometry as a hit test parameter. The following illustration shows the relationship between the hit test geometry (the blue circle) and the target object (the red square).
