Constructor Detail

FreeformViewport

public FreeformViewport()
Constructs a new FreeformViewport. This viewport must use graphics translation to scroll the FreeformFigures inside of it.

Method Detail

readjustScrollBars

protected void readjustScrollBars()
Readjusts the scrollbars. In doing so, it gets the freeform extent of the contents and unions this rectangle with this viewport's client area, then sets the contents freeform bounds to be this unioned rectangle. Then proceeds to set the scrollbar values based on this new information.

Overrides:
readjustScrollBars in class Viewport
See Also:
Viewport.readjustScrollBars()

useLocalCoordinates

protected boolean useLocalCoordinates()
Returns true.

Overrides:
useLocalCoordinates in class Figure
Returns:
true if this Figure uses local coordinates
See Also:
Figure.useLocalCoordinates()
