Class WindowsDesktopProperty

java.lang.Object
com.jidesoft.plaf.WindowsDesktopProperty
All Implemented Interfaces:
UIDefaults.ActiveValue

public class WindowsDesktopProperty extends Object implements UIDefaults.ActiveValue
Wrapper for a value 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.

Note: This class is the same as DesktopProperty under com.sun.java.swing.plaf.windows. We keep a copy of it here is mainly for compatibility reason in case Sun decides to change the location of this class.

      UIManager.LazyValue method, returns the value from the desktop or the fallback value if the desktop value is null.

      createValue in interface UIDefaults.ActiveValue
    • getValueFromDesktop

      protected Object getValueFromDesktop()
      Returns the value from the desktop.
    • getDefaultValue

      protected Object getDefaultValue()
      Returns the value to use if the desktop property is null.
    • invalidate

      public void invalidate()
      Invalides the current value so that the next invocation of createValue will ask for the property again.
    • updateUI

      protected void updateUI()
      Requests that all components in the GUI hierarchy be updated to reflect dynamic changes in this look&feel. This update occurs by uninstalling and re-installing the UI objects. Requests are batched and collapsed into a single update pass because often many desktop properties will change at once.
    • configureValue

      protected Object configureValue(Object value)
      Configures the value as appropriate for a defaults property in the UIDefaults table.
    • getKey

      protected String getKey()
      Returns the key used to lookup the desktop properties value.
