方法详细资料

writeState

public void writeState(java.io.OutputStream outstream)
                throws java.io.IOException

抛出:

java.io.IOException

readState

public void readState(java.io.InputStream instream)
               throws java.io.IOException

抛出:

java.io.IOException

mouseMoved

public void mouseMoved(java.awt.event.MouseEvent e)

指定者:

mouseMoved 在接口中 java.awt.event.MouseMotionListener

mouseDragged

public void mouseDragged(java.awt.event.MouseEvent e)

指定者:

mouseDragged 在接口中 java.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.

clear

public void clear()

drawState

public void drawState()

Draw the entire panel from the state

getPreferredSize

public java.awt.Dimension getPreferredSize()

覆盖:

getPreferredSize 在类中 javax.swing.JComponent

paintComponent

public void paintComponent(java.awt.Graphics g)

覆盖:

paintComponent 在类中 javax.swing.JComponent
