Examples
The following example shows how to override default hit test support in a user-defined visual object. In this case, a new PointHitTestResult is created and returned from the overridden method.
// Override default hit test support in visual object.
protected override HitTestResult HitTestCore(PointHitTestParameters hitTestParameters)
{
Point pt = hitTestParameters.HitPoint;
// Perform custom actions during the hit test processing,
// which may include verifying that the point actually
// falls within the rendered content of the visual.
// Return hit on bounding rectangle of visual object.
return new PointHitTestResult(this, pt);
}
' Override default hit test support in visual object.
Protected Overrides Overloads Function HitTestCore(ByVal hitTestParameters As PointHitTestParameters) As HitTestResult
Dim pt As Point = hitTestParameters.HitPoint
' Perform custom actions during the hit test processing,
' which may include verifying that the point actually
' falls within the rendered content of the visual.
' Return hit on bounding rectangle of visual object.
Return New PointHitTestResult(Me, pt)
