initialize

public void initialize()

Description copied from interface: ComponentInterface

The initialize() method was designed to be a synchronization point after the constructor for the object has completed and a number of methods have been called on the component. This allows components with "expensive" set method calls to delay processing until all the sets have occurred.

initialize() should be called on a component after is it constructed :

     ListBox listBox = new ListBox();
     listBox.initialize();
     container.add( listBox );
 

Overriding initialize is now discouraged since it is generally better to override setDefaultValues and readObject to perform initialization.

By default (in the ComponentInterface implementation), initialize() does nothing. However, various components override initialize() to perform operations, and it should be called.

Although use of initialize() is now discouraged, initialize() is also called by the validateObject method after a component is deserialized. This allows components which need processing during creation and deserialization to have a common place to perform operations. Adding event handlers to subcomponents is a typical use of the initialize method.

Specified by:

initialize in interface com.sas.ComponentInterface

Overrides:

initialize in class ScrollPaneVisualComponent

See Also:

ComponentInterface.initialize()

setDefaultValues

public void setDefaultValues()

Sets the initial values to the default values. This method is called by the Component constructors. The setDefaultValues method of each class is responsible for setting its own initial values.

Specified by:

setDefaultValues in interface ContainerInterface

Specified by:

setDefaultValues in interface VisualInterface

Specified by:

setDefaultValues in interface com.sas.ComponentInterface

Overrides:

setDefaultValues in class ScrollPaneContainerComponent

See Also:

ContainerInterface.setDefaultValues()

processContainerEvent

protected void processContainerEvent(java.awt.event.ContainerEvent event)

Overrides:

processContainerEvent in class java.awt.Container
