Specified by:

start in interface ICommandFactory

Overrides:

start in class AddCommandFactoryBase

Parameters:

requester - The object requesting this command to start

stop

public void stop()

Description copied from interface: ICommandFactory

clear

public void clear()

processMouseDown

public boolean processMouseDown(com.google.gwt.event.dom.client.MouseDownEvent event)

Description copied from interface: MouseDownProcessor

Processes a mousedown event

Specified by:

processMouseDown in interface MouseDownProcessor

Returns:

true if the receiver has processed the event, false if processing should be delegated to another object.
