public class UseCase1Dc
extends AbstractDialogDc
implements DialogDc

UseCase1Dc is the presentation component of a typical CRUD (Create, Read, Update, Delete) business application. It uses the net.sf.cuf.xfer library to do asynchronous data loading and uses the BlockEvent and ShowStatusEvent to provide the user with feedback. The quite complicated UI work is done in the presentation component (UseCase1Pc).

public boolean canPassivate()

We can only passivate if there is no dirty data

Specified by:

canPassivate in interface SimpleLifeCycle

Overrides:

canPassivate in class AbstractDialogDc

Returns:

true if there is no data to save

doActivate

public void doActivate(Map<String,? super Object> pArgs)

Called from the dialog coordinator to tell the dialog to switch to the active state.

Specified by:

doActivate in interface SimpleLifeCycle

Parameters:

pArgs - arguments, key is a String, value is any suitable objekt for the key

doPassivate

public void doPassivate(Map<String,? super Object> pArgs)

Called from the dialog coordinator to tell the dialog to switch to the passive state.

Specified by:
