UIElement.OnIsMouseDirectlyOverChanged Method


Invoked when an unhandled IsMouseDirectlyOverChanged event is raised on this element. Implement this method to add class handling for this event.

 virtual void OnIsMouseDirectlyOverChanged(System::Windows::DependencyPropertyChangedEventArgs e);
protected virtual void OnIsMouseDirectlyOverChanged (System.Windows.DependencyPropertyChangedEventArgs e);
abstract member OnIsMouseDirectlyOverChanged : System.Windows.DependencyPropertyChangedEventArgs -> unit
override this.OnIsMouseDirectlyOverChanged : System.Windows.DependencyPropertyChangedEventArgs -> unit
Protected Overridable Sub OnIsMouseDirectlyOverChanged (e As DependencyPropertyChangedEventArgs)



This virtual method is raised when the value of the IsMouseDirectlyOver dependency property changes its value. The virtual method is raised first and can manipulate the event data as necessary. Then the IsMouseDirectlyOverChanged event is raised with that same event data instance. Notice that the IsMouseDirectlyOverChanged event is not a routed event. Therefore, you cannot mark it as handled in the class handler.

This method has no default implementation. Because an intermediate class in the inheritance might implement this method, we recommend that you call the base implementation in your implementation. You may call base either before or after your special handling, depending on your requirements.
