Constructor Detail

BasicDrawingPanel

public BasicDrawingPanel()

Creates a panel with white background

BasicDrawingPanel

public BasicDrawingPanel(int width,
                         int height)

Constructor which allows the default height and width to be overridden

Method Detail

getPreferredSize

public java.awt.Dimension getPreferredSize()

Returns the initial preferred size of the drawing panel. This method is called by the layout manager during the creation of the corresponding drawing frame.

Returns:

The dimension of the drawing panel.

setPreferredSize

public void setPreferredSize(int w,
                             int h)

Set the preferred size

setPredecessor

public void setPredecessor(BasicDrawingPanel pre)

getImage

public java.awt.Image getImage()

Get the image associated with this panel. Used for shuffling the panels down

setImage

public void setImage(java.awt.Image img)

redraw

public void redraw()

Calls repaint() followed by delay(). Since these two methods are being called very frequently in order, the redraw() method is constructed to save typing.

makeOffScreenBuffer

protected void makeOffScreenBuffer(java.awt.Dimension d)

clear

public void clear()

paint

public void paint(java.awt.Graphics g)

Method to draw objects on the drawing panel.

getOffScreenGraphics

public java.awt.Graphics getOffScreenGraphics()

drawFromOffscreen

public void drawFromOffscreen()

shuffleDown

public void shuffleDown()

Shuffle the images down from this panel to the previous one
