public System.Windows.Media.Visual VisualHit { get; }
member this.VisualHit : System.Windows.Media.Visual
Public ReadOnly Property VisualHit As Visual
Property Value
A Visual object that represents the hit test result.
Examples
The following example shows how to access the VisualHit property in a hit test results callback function.
// Return the result of the hit test to the callback.
public HitTestResultBehavior MyHitTestResult(HitTestResult result)
{
// Add the hit test result to the list that will be processed after the enumeration.
hitResultsList.Add(result.VisualHit);
// Set the behavior to return visuals at all z-order levels.
return HitTestResultBehavior.Continue;
}
' Return the result of the hit test to the callback.
Public Function MyHitTestResult(ByVal result As HitTestResult) As HitTestResultBehavior
' Add the hit test result to the list that will be processed after the enumeration.
hitResultsList.Add(result.VisualHit)
' Set the behavior to return visuals at all z-order levels.
Return HitTestResultBehavior.Continue
End Function
Remarks
The VisualHit value could potentially represent multiple visual objects during a single hit test. The hit test callback method defines the actions you perform when a hit test is identified on a particular visual object in the visual tree. After you perform the actions, you return a HitTestResultBehavior value that determines whether to continue the enumeration of any other visual objects. The order of enumeration of returned visual objects is by z-order on the rendering plane.
