Method Detail
-
writeState
public void writeState(java.io.OutputStream outstream) throws java.io.IOException
- Throws:
java.io.IOException
-
readState
public void readState(java.io.InputStream instream) throws java.io.IOException
- Throws:
java.io.IOException
-
mouseMoved
public void mouseMoved(java.awt.event.MouseEvent e)
- Specified by:
mouseMoved
in interfacejava.awt.event.MouseMotionListener
-
mouseDragged
public void mouseDragged(java.awt.event.MouseEvent e)
- Specified by:
mouseDragged
in interfacejava.awt.event.MouseMotionListener
-
drawPoint
public void drawPoint(DrawCommand c)
Adds pixel to queue and calls repaint() whenever we have MAX_ITEMS pixels in the queue or when MAX_TIME msecs have elapsed (whichever comes first). The advantage compared to just calling repaint() after adding a pixel to the queue is that repaint() can most often draw multiple points at the same time.
