. Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans has been added to the java.beans
package. Please see XMLEncoder

public Class<? extends ComponentUI> getUIClass(String uiClassID, ClassLoader uiClassLoader)
get(uidClassID)
must be the String
name of a class that implements the corresponding ComponentUI
class. If the class hasn't been loaded before, this method looks up the class with uiClassLoader.loadClass()
if a non null
class loader is provided, classForName()
otherwise. If a 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 necessary to call it directly.
uiClassID
- a string containing the class IDuiClassLoader
