Constructor Detail

CPanel

public CPanel()
Create a new CPanel with a double buffer and a flow layout


CPanel

public CPanel(boolean isDoubleBuffered)
Creates a new CPanel with FlowLayout and the specified buffering strategy. If isDoubleBuffered is true, the CPanel will use a double buffer.

Parameters:
isDoubleBuffered - a boolean, true for double-buffering, which uses additional memory space to achieve fast, flicker-free updates

CPanel

public CPanel(LayoutManager layout)
Create a new buffered CPanel with the specified layout manager

Parameters:
layout - the LayoutManager to use

CPanel

public CPanel(LayoutManager layout,
              boolean isDoubleBuffered)
Creates a new CPanel with the specified layout manager and buffering strategy.

Parameters:
layout - the LayoutManager to use
isDoubleBuffered - a boolean, true for double-buffering, which uses additional memory space to achieve fast, flicker-free updates
