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.

Constructor Summary

WindowsDesktopProperty(String key, Object fallback, Toolkit toolkit)
Creates a DesktopProperty.

WindowsDesktopProperty(String key, Object fallback, Toolkit toolkit, float fontSize)

WindowsDesktopProperty(String key, Object fallback, Toolkit toolkit, float fontSize, int fontStyle)

Method Summary

protected Object	configureValue(Object value) Configures the value as appropriate for a defaults property in the UIDefaults table.
Object	createValue(UIDefaults table) UIManager.LazyValue method, returns the value from the desktop or the fallback value if the desktop value is null.
protected Object	getDefaultValue() Returns the value to use if the desktop property is null.
protected String	getKey() Returns the key used to lookup the desktop properties value.
protected Object	getValueFromDesktop() Returns the value from the desktop.
void	invalidate() Invalides the current value so that the next invocation of createValue will ask for the property again.
protected void	updateUI() Requests that all components in the GUI hierarchy be updated to reflect dynamic changes in this look&feel.

Method Detail

createValue

public Object createValue(UIDefaults table)

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

Specified by:

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.
