Interface ContainerPeer

All Superinterfaces:

ComponentPeer

All Known Subinterfaces:

DialogPeer, FileDialogPeer, FramePeer, PanelPeer, ScrollPanePeer, WindowPeer

public interface ContainerPeer
extends ComponentPeer

The peer interface for Container. This is the parent interface for all container like widgets. The peer interfaces are intended only for use in porting the AWT. They are not intended for use by application developers, and developers should not implement peers nor invoke any of the peer methods directly on the peer instances.

Method Detail

getInsets

Insets getInsets()

Returns the insets of this container. Insets usually is the space that is occupied by things like borders.

Returns:

the insets of this container

beginValidate

void beginValidate()

Notifies the peer that validation of the component tree is about to begin. This is called from Container.validate(), before validateTree() is called.

See Also:

Container.validate()

endValidate

void endValidate()

Notifies the peer that validation of the component tree is finished. This is called from Container.validate(), right after validateTree() returned.

See Also:

Container.validate()

beginLayout

void beginLayout()

Notifies the peer that layout is about to begin. This is called from Container.validateTree(), before the container itself and its children are laid out.

See Also:

Container.validateTree()

endLayout

void endLayout()

Notifies the peer that layout is finished. This is called from Container.validateTree(), after the container and its children have been laid out.

See Also:

Container.validateTree()

restack

void restack()

Restacks native windows - children of this native window - according to Java container order.

Since:

1.5

isRestackSupported

boolean isRestackSupported()

Indicates availability of restacking operation in this container.

Returns:

Returns true if restack is supported, false otherwise

Since:

1.5
