JScrollPane()
Create a JScrollPane, you can specified a Component to be view, then here will create a JViewport to manager the view's scroll, or a Viewportable to be the view, it mananger the scroll itself. If view is not instanceof either, no view will be viewed.
viewOrViewport | the scroll content component or a Viewportable |
vsbPolicy | SCROLLBAR_AS_NEEDED or SCROLLBAR_NEVER or SCROLLBAR_ALWAYS, default SCROLLBAR_AS_NEEDED |
hsbPolicy | SCROLLBAR_AS_NEEDED or SCROLLBAR_NEVER or SCROLLBAR_ALWAYS, default SCROLLBAR_AS_NEEDED |

Resets the UI property to a value from the current look and feel.
Component subclasses must override this method
like this:
public void updateUI() {
setUI((SliderUI)UIManager.getUI(this);
}
public function setUI(newUI:ScrollPaneUI):VoidDescription copied from Component
Sets the look and feel delegate for this component.
Component subclasses generally override this method
to narrow the argument type. For example, in JSlider:
public void setUI(SliderUI newUI) {
super.setUI(newUI);
}
Additionally Component subclasses must provide a
getUI method that returns the correct type. For example:
public SliderUI getUI() {
return (SliderUI)ui;
}
public function getUIClassID():StringDescription copied from Component
Returns the UIDefaults key used to
look up the name of the org.aswing.plaf.ComponentUI
class that defines the look and feel
for this component. Most applications will never need to
call this method. Subclasses of Component that support
pluggable look and feel should override this method to
return a UIDefaults key that maps to the
ComponentUI subclass that defines their look and feel.
public function setLayout(layout:LayoutManager):Void
| Error | when the layout is not ScrollPaneLayout instance. |
public function setView(viewOrViewport:Object):Void
Sets the view to viewed and scrolled by this scrollpane.
if this view is not a Viewportable implementation,
then here will create a JViewport to manager the view's scroll,
else the Viewportable will be the viewport.
If view is not instanceof either, no view will be set.
If you want to make a component viewed by your way, you have two way:
Viewportable implementation.
Viewportable likes JViewport, recommend
you extends the JViewport, then make your component to be the viewport's view like
JViewport does.
setView(view:Component)
setView(view:Viewportable)
viewOrViewport | a component or a Viewportable object. |
public function setViewportView(view:Component):Void
Creates a JViewport and then sets its view. Applications
that don't provide the view directly to the JScrollPane
constructor
should use this method to specify the scrollable child that's going
to be displayed in the scrollpane. For example:
JScrollPane scrollpane = new JScrollPane(); scrollpane.setViewportView(myBigComponentToScroll);Applications should not add children directly to the scrollpane.
view | the component to add to the viewport |
public function getViewportView():ComponentReturns the view currently in the scrollpane.
public function getVisibleRect():RectangleReturns the visible extent rectangle related the current scroll properties.

public function addAdjustmentListener(func:Function, obj:Object):ObjectShortcut to and ON_ADJUSTMENT_VALUE_CHANGED listener.
addAdjustmentListener(func:Function)
addAdjustmentListener(func:Function, obj:Object)
func | the function which want to handler the event. |
obj | context in which to run the function of param func. |
public function setHorizontalScrollBar(horizontalScrollBar:JScrollBar):VoidAdds the scrollbar that controls the viewport's horizontal view position to the scrollpane.
public function setVerticalScrollBar(verticalScrollBar:JScrollBar):VoidAdds the scrollbar that controls the viewport's vertical view position to the scrollpane.
