Field

int	BLIT_SCROLL_MODE Use `graphics.copyArea` to implement scrolling.
int	SIMPLE_SCROLL_MODE This mode uses the very simple method of redrawing the entire contents of the scrollpane each time it is scrolled.

Constructor

	JViewport() Creates a `JViewport`.

Method

Component	add(Component comp) Appends the specified component to the end of this container.
Component	add(String name, Component comp) Adds the specified component to this container.
void	addChangeListener(ChangeListener l) Adds a `ChangeListener` to the list that is notified each time the view's size, position, or the viewport's extent size has changed.
ActionMap	getActionMap() Returns the `ActionMap` used to determine what `Action` to fire for particular `KeyStroke` binding.
Rectangle	getBounds() Gets the bounds of this component in the form of a Rectangle object.
Component	getComponent(int n) Gets the nth component in this container.
Component[]	getComponents() Gets all the components in this container.
Dimension	getExtentSize() Returns the size of the visible part of the view in view coordinates.
int	getHeight() Returns the current height of this component.
InputMap	getInputMap(int condition) Returns the `InputMap` that is used during `condition`.
Container	getParent() Gets the parent of this component.
Component	getView() Returns the `JViewport`'s one child or `null`.
Point	getViewPosition() Returns the view coordinates that appear in the upper left hand corner of the viewport, or 0,0 if there's no view.
Rectangle	getViewRect() Returns a rectangle whose origin is `getViewPosition` and size is `getExtentSize`.
Dimension	getViewSize() If the view's size hasn't been explicitly set, return the preferred size, otherwise return the view's current size.
Rectangle	getVisibleRect() Returns the `Component`'s "visible rectangle" - the intersection of this component's visible rectangle, `new Rectangle(0, 0, getWidth(), getHeight())`, and all of its ancestors' visible rectangles.
int	getWidth() Returns the current width of this component.
void	paint(Graphics g) Depending on whether the `backingStore` is enabled, either paint the image through the backing store or paint just the recently exposed part, using the backing store to "blit" the remainder.
void	scrollRectToVisible(Rectangle contentRect) Scrolls the view so that `Rectangle` within the view becomes visible.
void	setBackground(Color bg) Sets the background color of this component.
void	setMaximumSize(Dimension maximumSize) Sets the maximum size of this component to a constant value.
void	setPreferredSize(Dimension preferredSize) Sets the preferred size of this component.
void	setScrollMode(int mode) Used to control the method of scrolling the viewport contents.
void	setView(Component view) Sets the `JViewport`'s one lightweight child (`view`), which can be `null`.
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.
void	setViewSize(Dimension newSize) Sets the size of the view.
Dimension	toViewCoordinates(Dimension size) Converts a size in pixel coordinates to view coordinates.
Point	toViewCoordinates(Point p) Converts a point in pixel coordinates to view coordinates.
