Class CurrencyWidgetsInitializer

java.lang.Object

com.portal.app.comp.CurrencyWidgetsInitializer

public class CurrencyWidgetsInitializer
extends Object

Initializes primary and secondary combo boxes controls. The expected use is for a listener to be set on the primary currency widget. Then when selectPrimaryCurrency is called to initialize the primary currency combo box or whenever the user subsequently selects a new primary currency, the secondary currency widget can be initialized by a call to selectSecondaryCurrency. For example,
public void itemStateChanged(java.awt.event.ItemEvent event) { Object object = event.getSource(); if (event.getStateChange() == ItemEvent.SELECTED) { if (object == mPrimaryCurrencyCB) { mCurrencyWidgetsInitializer.selectSecondaryCurrency(); } } }
Additional convenience methods are also provided to do sets and look-ups.
