  +--oracle.dss.thin.beans.InitEventDataObject

All Implemented Interfaces:

oracle.cabo.ui.data.DataObject

public class InitEventDataObject

extends java.lang.Object

implements oracle.cabo.ui.data.DataObject

The InitEventDataObject provides the JavaScript for an OnClick event on a UIX Component, which can be a button, image, or other html elements. To set the InitEventDataObject on a UIX Component, two steps need to be taken.

1. The UIX Component needs to have its OnClick attribute set with a DataBoundValue, so that it will fetch its value from the oracle.cabo.ui.RenderingContext.

   initButtonBean.setAttributeValue(ButtonBean.ON_CLICK_ATTR,new DataBoundValue("MyNamespace","MyInitDataObject",""));
   

2. Then, the InitEventDataObject will need to be set on the RenderingContext before the UINode is rendered.

   context.setDataObject("MyNamespace","MyInitDataObject",new InitEventDataObject(target));
   

Initializing ThinBeanDialogs

The EventTarget that is specified on the InitEventDataObject must be used to specify the name of the ThinBeanDialog that will handle the init event. When a ThinBeanDialog handles the init event, it will send any ThinBeanDialogListener registered with the ThinBeanDialog an InitEvent. The InitEvent itself does not have any parameters, but they can be added by an application if necessary.

Extra parameters can be added to the EventTarget, so that the init event can deliver application context to the ThinBeanDialog that is handling the request. For example, if an application has multiple views open at the same time and where each view can be printed, then the button that prints a specific view will need to pass the view's name to the PrintOptions dialog, so that the correct view can be set on the PrintOptions dialog.
