public class UIDefaults

extends Hashtable

See Also:

UIManager

UIDefaults.ActiveValue

This class enables one to store an entry in the defaults table that's constructed each time it's looked up with one of the getXXX(key) methods.

UIDefaults.LazyValue

This class enables one to store an entry in the defaults table that isn't constructed until the first time it's looked up with one of the getXXX(key) methods.

UIDefaults()

Create an empty defaults table.

UIDefaults(Object[])

Create a defaults table initialized with the specified key/value pairs.

addPropertyChangeListener(PropertyChangeListener)

Add a PropertyChangeListener to the listener list.

firePropertyChange(String, Object, Object)

Support for reporting bound property changes.

get(Object)

Returns the value to which the specified key is mapped in this hashtable.

getBorder(Object)

If the value of key is a Border return it, otherwise return null.

getColor(Object)

If the value of key is a Color return it, otherwise return null.

getFont(Object)

If the value of key is a Font return it, otherwise return null.

getIcon(Object)

If the value of key is an Icon return it, otherwise return null.

getString(Object)

If the value of key is a String return it, otherwise return null.

getUI(JComponent)

Create an ComponentUI implementation for the specified component.

getUIClass(String)

The value of get(uidClassID) must be the String name of a class that implements the corresponding ComponentUI class.

getUIError(String)

If getUI() fails for any reason, it calls this method before returning null.

put(Object, Object)

Set the value of key to value.

putDefaults(Object[])

Put all of the key/value pairs in the database and unconditionally generate one PropertyChangeEvent.

removePropertyChangeListener(PropertyChangeListener)

Remove a PropertyChangeListener from the listener list.

public UIDefaults()

Create an empty defaults table.

public UIDefaults(Object[] keyValueList)

Create a defaults table initialized with the specified key/value pairs. For example:

Object[] uiDefaults = {
"Font", new Font("Dialog", Font.BOLD, 12),
"Color", Color.red,
"five", new Integer(5)
}
UIDefaults myDefaults = new UIDefaults(uiDefaults);
 

public Object get(Object key)

Returns the value to which the specified key is mapped in this hashtable.

Overrides:

get in class Hashtable

public Object put(Object key,
                  Object value)

Set the value of key to value. If key is a string and the new value isn't equal to the old one, fire a PropertyChangeEvent. If value is null, the key is removed from the table.

Overrides:

put in class Hashtable

putDefaults, put

public void putDefaults(Object[] keyValueList)

Put all of the key/value pairs in the database and unconditionally generate one PropertyChangeEvent. The events oldValue and newValue will be null and its propertyName will be "UIDefaults".

See Also:

put, put

public Font getFont(Object key)

If the value of key is a Font return it, otherwise return null.

public Color getColor(Object key)

If the value of key is a Color return it, otherwise return null.

public Icon getIcon(Object key)

If the value of key is an Icon return it, otherwise return null.

public Border getBorder(Object key)

If the value of key is a Border return it, otherwise return null.

public String getString(Object key)

If the value of key is a String return it, otherwise return null.

public Class getUIClass(String uiClassID)

The value of get(uidClassID) must be the String name of a class that implements the corresponding ComponentUI class. This method looks up the class with classForName() and returns it. If no mapping for uiClassID exists or if the specified class can't be found, return null.

This method is used by getUI, it's usually not neccessary to call it directly.

Returns:

The value of Class.forName(get(uidClassID)).

getUI

protected void getUIError(String msg)

If getUI() fails for any reason, it calls this method before returning null. Subclasses may choose to do more or less here.

Parameters:

msg - Message string to print.

See Also:

getUI

public ComponentUI getUI(JComponent target)

Create an ComponentUI implementation for the specified component. In other words create the look and feel specific delegate object for target. This is done in two steps:

• Lookup the name of the ComponentUI implementation class under the value returned by target.getUIClassID().
• Use the implementation classes static createUI() method to construct a look and feel delegate.

public void addPropertyChangeListener(PropertyChangeListener listener)

Add a PropertyChangeListener to the listener list. The listener is registered for all properties.

A PropertyChangeEvent will get fired whenever a default is changed.

Parameters:

listener - The PropertyChangeListener to be added

See Also:

PropertyChangeSupport

public void removePropertyChangeListener(PropertyChangeListener listener)

Remove a PropertyChangeListener from the listener list. This removes a PropertyChangeListener that was registered for all properties.

Parameters:

listener - The PropertyChangeListener to be removed

See Also:

PropertyChangeSupport

protected void firePropertyChange(String propertyName,
                                  Object oldValue,
                                  Object newValue)

Support for reporting bound property changes. If oldValue and newValue are not equal and the PropertyChangeEvent listener list isn't empty, then fire a PropertyChange event to each listener.

Parameters:

propertyName - The programmatic name of the property that was changed.

oldValue - The old value of the property.

newValue - The new value of the property.
