C# 클래스 System.Windows.Controls.InteractionHelper

The InteractionHelper provides controls with support for all of the common interactions like mouse movement, mouse clicks, key presses, etc., and also incorporates proper event semantics when the control is disabled.

OnIsEnabledChanged ( object sender, System.Windows.DependencyPropertyChangedEventArgs e ) : void	Handle changes to the control's IsEnabled property.
OnIsReadOnlyChanged ( bool value ) : void
OnLoaded ( object sender, RoutedEventArgs e ) : void	Handle the control's Loaded event.
UpdateVisualState ( bool useTransitions ) : void	Update the visual state of the control. UpdateVisualState works differently than the rest of the injected functionality. Most of the other events are overridden by the calling class which calls Allow, does what it wants, and then calls Base. UpdateVisualState is the opposite because a number of the methods in InteractionHelper need to trigger it in the calling class. We do this using the IUpdateVisualState internal interface.
