Sets the layout manager for this container to the specified layout manager.

Overrides:

setLayout in class Container

Parameters:

manager - The new layout manager for this container.

Parameters:

glassPane - TODO

addImpl

protected void addImpl(Component comp,
           Object constraints,
           int index)

Description copied from class: Container

This method is called by all the add() methods to perform the actual adding of the component. Subclasses who wish to perform their own processing when a component is added should override this method. Any subclass doing this must call the superclass version of this method in order to ensure proper functioning of the container.

Overrides:

addImpl in class Container

Parameters:

comp - The component to be added.

constraints - The layout constraints for this component, or null if there are no constraints.

index - The index in the component list to insert this child at, or -1 to add at the end of the list.

getAccessibleContext

public AccessibleContext getAccessibleContext()

Description copied from class: Applet

Gets the AccessibleContext associated with this applet, creating one if necessary. This always returns an instance of Applet.AccessibleApplet.

Specified by:

getAccessibleContext in interface Accessible

Overrides:

getAccessibleContext in class Applet

Returns:

the accessibility context of this applet

getJMenuBar

public JMenuBar getJMenuBar()

setJMenuBar

public void setJMenuBar(JMenuBar menubar)

paramString

protected String paramString()

Description copied from class: Container

Returns a string representing the state of this container for debugging purposes.

Overrides:

paramString in class Container

Returns:

A string representing the state of this container.

processKeyEvent

protected void processKeyEvent(KeyEvent e)

Description copied from class: Component

Called when a key event is dispatched and component events are enabled. This method passes the event along to any listeners that are attached.

Overrides:

processKeyEvent in class Component

Parameters:

e - the KeyEvent to process

See Also:

KeyListener, Component.addKeyListener(KeyListener), Component.enableEvents(long)

remove

public void remove(Component comp)

Description copied from class: Container

Removes the specified component from this container.

Overrides:

remove in class Container

Parameters:

comp - The component to remove from this container.

isRootPaneCheckingEnabled

protected boolean isRootPaneCheckingEnabled()

setRootPaneCheckingEnabled

protected void setRootPaneCheckingEnabled(boolean enabled)

update

public void update(Graphics g)

Description copied from class: Container

Updates this container. The implementation of this method in this class forwards to any lightweight components in this container. If this method is subclassed, this method should still be invoked as a superclass method so that lightweight components are properly drawn.

Overrides:

update in class Container

Parameters:

g - The graphics context for this update.

Component.paint(Graphics), Component.repaint()
