public Interface ConstrainableGraphics

Known Direct Implementers
sun.java2d.SunGraphics2D
This interface can be implemented on a Graphics object to allow the lightweight component code to permanently install a rectangular maximum clip that cannot be extended with setClip and which works in conjunction with the hit() and getTransform() methods of Graphics2D to make it appear as if there really was a component with these dimensions.

Method Summary

Modifier and TypeMethod and Description
public void
constrain(int x, int y, int w, int h)

Constrain this graphics object to have a permanent device space origin of (x, y) and a permanent maximum clip of (x,y,w,h).

Method Detail

constrainback to summary
public void constrain(int x, int y, int w, int h)

Constrain this graphics object to have a permanent device space origin of (x, y) and a permanent maximum clip of (x,y,w,h). Calling this method is roughly equivalent to: g.translate(x, y); g.clipRect(0, 0, w, h); except that the clip can never be extended outside of these bounds, even with setClip() and for the fact that the (x,y) become a new device space coordinate origin. These methods are recursive so that you can further restrict the object by calling the constrain() method more times, but you can never enlarge its restricted maximum clip.
