Method Detail

firePropertyChange

protected void firePropertyChange(java.lang.String propertyName,
                                  java.lang.Object oldValue,
                                  java.lang.Object newValue)

This method serves to send a PropertyChangeEvent instance on the Event Dispatch Thread.

Parameters:

propertyName - the name of the property

oldValue - the former value of this property if any

newValue - the current value of this property

setProgress

protected void setProgress(int progress)

This method sends a PropertyChangeEvent with property set to "progress" on the Event Dispatch Thread. The method is executed asynchronously on the EDT. The event is updated just before being sent on the thread to make sure the last progress will be recorded.

Parameters:

progress - an integer between 0 and 100. Any value outside this range will be set to the limit.

addPropertyChangeListener

public void addPropertyChangeListener(java.beans.PropertyChangeListener listener)

This method adds a PropertyChangeListener instance to the list of listeners. The instance is added only if it is not already contained in the list of listeners.

Parameters:

listener - the PropertyChangeListener instance to be added

removePropertyChangeListener

public void removePropertyChangeListener(java.beans.PropertyChangeListener listener)

This method removes a particular PropertyChangeListener instance from the list of listeners. Nothing happens if the listeners collection does not contain the instance.

Parameters:

listener - the PropertyChangeListener instance to be removed
