Method Detail

addExceptionListener
public void addExceptionListener(IExceptionListener l)(Code)
	Adds a listener.

addWorkerStatusChangeListener
public void addWorkerStatusChangeListener(IWorkerStatusChangeListener l)(Code)

cancel
public void cancel()(Code)

cancelled
public boolean cancelled()(Code)

clearDisplayText
public void clearDisplayText()(Code)
	Clears the text displayed in the status bar - without any delay

clearDisplayTextWithDelay
