Constructor Summary
`SwingContainerPeer(Container awtCont)` Creates a new SwingContainerPeer.

Method Summary
`protected void`	`addHeavyweightDescendent(Component comp)` Registers a heavyweight descendent.
`void`	`beginLayout()` Called before the layout of this containers begins.
`void`	`beginValidate()` Called before the validation of this containers begins.
`void`	`cancelPendingPaint(int x, int y, int width, int height)` This method is not used at the moment.
`void`	`endLayout()` Called after the layout of this containers ended.
`void`	`endValidate()` Called after the validation of this containers ended.
`protected Component[]`	`getHeavyweightDescendents()` Returns an array of all registered heavyweight descendents.
`Insets`	`getInsets()` Returns the insets of the container.
`protected void`	`handleKeyEvent(KeyEvent e)` Handles key events on the component.
`protected void`	`handleMouseEvent(MouseEvent ev)` Handles mouse events by dispatching it to the correct component.

SwingContainerPeer

public SwingContainerPeer(Container awtCont)

Creates a new SwingContainerPeer.
Parameters:
awtCont -

addHeavyweightDescendent

protected void addHeavyweightDescendent(Component comp)

Registers a heavyweight descendent. This is then painted by peerPaintChildren(Graphics).
Parameters:
comp - the descendent to register

beginLayout

public void beginLayout()

Called before the layout of this containers begins.
Specified by:
beginLayout in interface ContainerPeer

beginValidate

public void beginValidate()

Called before the validation of this containers begins.
Specified by:
beginValidate in interface ContainerPeer

cancelPendingPaint

public void cancelPendingPaint(int x,
                               int y,
                               int width,
                               int height)

This method is not used at the moment.
Specified by:
