  com.abstractics.xmlpanel.swing.componentcreator.ComponentFactory

public class ComponentFactory

extends java.lang.Object

Singleton factory that can create Swing components from XML. The factory is loaded with XmlPanelComponentCreator objects that handle the details of how the XML is converted into a component.
XmlPanelComponentCreator objects can be added to the factory at runtime via the addXmlPanelComponentCreator method.

The factory is preloaded with the following creators:

• GenericClassComponentCreator for type "label", creates javax.swing.JLabel
• GenericClassComponentCreator for type "text", creates javax.swing.JTextField
• GenericClassComponentCreator for type "button", creates javax.swing.JButton
• GenericClassComponentCreator for type "textarea", creates javax.swing.JTextArea
• GenericClassComponentCreator for type "radio", creates javax.swing.JRadioButton
• GenericClassComponentCreator for type "checkbox", creates javax.swing.JCheckBox
• JScrollPaneCreator
