All Implemented Interfaces:

VDUScrollBar, VirtualTerminalComponent, java.awt.Adjustable, java.awt.event.AdjustmentListener, java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, java.util.EventListener, javax.accessibility.Accessible

public class SwingScrollBar
extends javax.swing.JScrollBar
implements VDUScrollBar, java.awt.event.AdjustmentListener

Implementation of a VDUScrollBar that uses a Swing JScrollBar to provide a component that may be used for scrolling a VDUDisplay.

When this component is added to the terminal display, it is automatically registered as the scroll bar for the terminal panel.

Description copied from interface: VDUScrollBar

Add to the list of listeners to be informed of any changes to the state of this scrollbar. For example, when the user drags the scrollbar using the mouse.

Specified by:

addScrollListener in interface VDUScrollBar

Parameters:

listener - listener to add

removeScrollListener

public void removeScrollListener(ScrollListener listener)

Description copied from interface: VDUScrollBar

Remove from the list of listeners to be informed when the state of the scrollbar changes in some way.

Specified by:

removeScrollListener in interface VDUScrollBar

Parameters:

listener - listener to remove

adjustmentValueChanged

public void adjustmentValueChanged(java.awt.event.AdjustmentEvent e)

Specified by:

adjustmentValueChanged in interface java.awt.event.AdjustmentListener

init

public void init(VirtualTerminal terminal)

Description copied from interface: VirtualTerminalComponent

Initialise the virtual terminal component

Specified by:

init in interface VirtualTerminalComponent

getComponent

public java.awt.Component getComponent()

Description copied from interface: VirtualTerminalComponent
