| Modifier and Type | Method and Description |
|---|---|
protected LayoutManager |
createLayoutManager()
Subclasses can override this to install a different layout manager (or
null) in the constructor. |
protected PScrollDirector |
createScrollDirector()
Subclasses can override this to install a different scroll director in
the constructor.
|
void |
fireStateChanged()
Notifies all
ChangeListeners when the views size, position,
or the viewports extent size has changed. |
PScrollDirector |
getScrollDirector()
Returns the scroll director on this viewport.
|
Point |
getViewPosition()
Gets the view position from the scroll director based on the current
extent size.
|
Dimension |
getViewSize()
Gets the view size from the scroll director based on the current extent
size.
|
Dimension |
getViewSize(Rectangle2D r)
Gets the view size from the scroll director based on the specified extent
size.
|
void |
setScrollDirector(PScrollDirector scrollDirector)
Set the scroll director on this viewport.
|
void |
setView(Component view)
Overridden to throw an exception if the view is not a PCanvas.
|
void |
setViewPosition(Point p)
Sets the view coordinates that appear in the upper left hand corner of
the viewport, does nothing if there's no view.
