java.awt.Container

javax.swing.JComponent

furbelow.Panner

All Implemented Interfaces:

ImageObserver, MenuContainer, Serializable

public class Panner
extends JComponent

Component which scales any given JComponent into its bounds. The visible portion of the JComponent (as reported by JComponent.getVisibleRect()) is drawn as a rectangle in the scaled image. Dragging the rectangle will move the visible portion of the panned component within its scrolling context.

isAttached

public boolean isAttached()

detach

public void detach()

setViewportCenter

public void setViewportCenter(Point where)

Sets the center point of the current viewport. Coordinates are relative to the Panner bounds. The viewport bounds will always be contained within the thumbnail image.

Parameters:

where -

getDrawingSize

protected Dimension getDrawingSize(JComponent component)

setCentered

public void setCentered(boolean set)

Set the thumbnail alignment within the available space.

isCentered

public boolean isCentered()
