Constructor Detail

WhiteboardVisual

public WhiteboardVisual(Whiteboard w,
                        WhiteboardDisplay wd,
                        ClientApp c)

Constructor. The actual behavior on usaer input is defined by the anonymous inner-classes subclassing MouseAdapter and MouseMotionAdapter.

Parameters:

w - The associated whiteboard

wd - This visual's WhiteboardDisplay

c - The ClientApp

Method Detail

commitPrimitive

protected void commitPrimitive()

Finalizes the construction of a new primitive by invoking the factory to create a new WBPrimitive, wrapping it in a WBPrimitivePacket, and adding the packet to the whiteboard.

preSequence

boolean preSequence(java.awt.event.MouseEvent e)

Wrappers for the primitive entry points

postSequence

boolean postSequence(java.awt.event.MouseEvent e)

finalSequence

boolean finalSequence(WBPrimitive e)

setPrimitive

public boolean setPrimitive(java.lang.String d)

Sets the current drawing mode to a new primitive

Parameters:

n - The class name of the new primitive

paint

public void paint(java.awt.Graphics g)

Swing repaint method. This iterates over the Whiteboard's contents, drawing each primitive. Finally, it draws the current "shape in progress" as a rubberband.

Overrides:

paint in class javax.swing.JComponent
