Constructor Detail

WhiteboardPanel

public WhiteboardPanel(List<WhiteboardShape> displayList,
                       WhiteboardFrame wf)
WhiteboardPanel constructor.

Parameters:
displayList - Shapes to display
wf - WhiteboardFrame
Method Detail

drawGrid

public void drawGrid(boolean grid)
Method to draw/hide grid

Parameters:
grid - if true, draw grid

paintComponent

public void paintComponent(Graphics g)
Calls the UI delegate's paint method, if the UI delegate is non-null. We pass the delegate a copy of the Graphics object to protect the rest of the paint code from irrevocable changes (for example, Graphics.translate).

The passed in Graphics object might have a transform other than the identify transform installed on it. In this case, you might get unexpected results if you cumulatively apply another transform.

Overrides:
paintComponent in class JComponent
Parameters:
g - the Graphics object to protect
See Also:
JComponent.paint(java.awt.Graphics), ComponentUI

print

public int print(Graphics graphics,
                 PageFormat pageFormat,
                 int pageIndex)
Prints the page at the specified index into the specified Graphics context in the specified format. A PrinterJob calls the Printable interface to request that a page be rendered into the context specified by graphics. The format of the page to be drawn is specified by pageFormat. The zero based index of the requested page is specified by pageIndex. If the requested page does not exist then this method returns NO_SUCH_PAGE; otherwise PAGE_EXISTS is returned. The Graphics class or subclass implements the PrinterGraphics interface to provide additional information. If the Printable object aborts the print job then it throws a PrinterException.

Specified by:
print in interface Printable
Parameters:
graphics - the context into which the page is drawn
pageFormat - the size and orientation of the page being drawn
pageIndex - the zero based index of the page to be drawn
Returns:
PAGE_EXISTS if the page is rendered successfully or NO_SUCH_PAGE if pageIndex specifies a non-existent page.
