com.jidesoft.plaf.ExtWindowsDesktopProperty

All Implemented Interfaces:

UIDefaults.ActiveValue

public class ExtWindowsDesktopProperty
extends Object
implements UIDefaults.ActiveValue

Wrapper for multiple values from the desktop. The value is lazily looked up, and can be accessed using the UIManager.ActiveValue method createValue. If the underlying desktop property changes this will force the UIs to update all known Frames. You can invoke invalidate to force the value to be fetched again.
