Class ExtWindowsDesktopProperty

java.lang.Object
  com.jidesoft.plaf.ExtWindowsDesktopProperty

All Implemented Interfaces:

javax.swing.UIDefaults.ActiveValue

public class ExtWindowsDesktopProperty
extends java.lang.Object
implements javax.swing.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.

protected java.lang.Object[]	configureValue(java.lang.Object[] value) Configures the value as appropriate for a defaults property in the UIDefaults table.
java.lang.Object	createValue(javax.swing.UIDefaults table) UIManager.LazyValue method, returns the value from the desktop or the fallback value if the desktop value is null.
protected java.lang.Object[]	getDefaultValue() Returns the value to use if the desktop property is null.
protected java.lang.String[]	getKeys() Returns the key used to lookup the desktop properties value.
protected java.lang.Object[]	getValueFromDesktop() Returns the value from the desktop.

Method Detail

createValue

public java.lang.Object createValue(javax.swing.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 javax.swing.UIDefaults.ActiveValue

getValueFromDesktop

protected java.lang.Object[] getValueFromDesktop()

Returns the value from the desktop.

getDefaultValue

protected java.lang.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 java.lang.Object[] configureValue(java.lang.Object[] value)

Configures the value as appropriate for a defaults property in the UIDefaults table.

configureValue

protected java.lang.Object configureValue(java.lang.Object value)

Configures the value as appropriate for a defaults property in the UIDefaults table.

getKeys

protected java.lang.String[] getKeys()

Returns the key used to lookup the desktop properties value.
