Constructor Detail

AbstractPaintlet

public AbstractPaintlet()

Method Detail

initialize

protected void initialize()

Initializes the members.

Overrides:

initialize in class AbstractOptionHandler

protected void finishInit()

Finishes the initialization in the constructor.

Calls memberChanged.

Overrides:

finishInit in class AbstractOptionHandler

See Also:

memberChanged()

isInitializing

protected boolean isInitializing()

Whether the paintlet is currently being initialized.

Returns:

true if the paintlet is currently being initialized

setPanel

public void setPanel(PaintablePanel value)

Sets the panel to use, null to disable painting.

Specified by:

setPanel in interface Paintlet

Parameters:

value - the panel to paint on

setPanel

public void setPanel(PaintablePanel value,
                     boolean register)

Sets the panel to use, null to disable painting.

Specified by:

setPanel in interface Paintlet

Parameters:

value - the panel to paint on

register - whether to register the paintlet

Sets whether the paintlet reacts with repaints to changes of its members.

Specified by:

setRepaintOnChange in interface Paintlet

Parameters:

value - if true then the paintlet repaints whenever members get changed

getRepaintOnChange

public boolean getRepaintOnChange()

Returns whether the paintlet reacts with repaints to changes of its members.
