No problem. I'll import your code and do a little massaging this evening. I'll post the cleaned up version, so you have something concrete to refer to.

Hi,
The snippet you attached had value models for each of the child widgets in the list item. I recommend using a value model and listener for the XY Container instead. In the listener can then get the data being set to the value model and use it to apply to the list item. Here is a snippet that may help you visualize what should change.

My app is able to iterate through the 50 entries in the vector model. The list widget is able to display each one of them without issue. You may need to spend some time debugging your app.

Can you please elaborate what eaxctly you are looking for? You have list of three items, each item is a static widget...right? what do you mean by response on handling three static widgets? do you mean selecting an item and displaying something?

You cannot select/focus individual static widget, the item widget (some container holding 3 static widgets) can be selected/focused. I don't know which container you are using for each item but if you want to access each static widget of the item, below code snippet may help you:
Install value model listener on the item container ( prop container with static and radio widget, in my case):
ISHELL_CreateInstance(pMe->piShell, AEECLSID_ValueModel, (void**)&pValueModel);
IWidget_SetModel(piwPropCnt, IValueModel_to_IModel(pValueModel));
LISTENER_Init(&pMe->mItemListener, (PFNLISTENER)ValueModelListener, (void*)pMe);
IValueModel_AddListener(pValueModel,&pMe->mItemListener);
Value model listener callback function:
static void ValueModelListener(listwidgetapp *pMe, ModelEvent *pEvent)
{
IPropContainer *picProp = NULL;
IWidget *piwProp = NULL;
IWidget *piwRadio = NULL;
IWidget *piwStatic = NULL;
if(pEvent->evCode == EVT_MDL_VALUE)
{
AECHAR *pszText = NULL;
int nLen;
IDecorator_GetWidget((IDecorator*)pMe->piwlist, &piwProp);
if (piwProp)
{
IWidget_QueryInterface(piwProp, AEEIID_IPropContainer, &picProp);
if (picProp)
{
piwRadio = IPropContainer_GetWidget(picProp, NULL, TRUE, FALSE);
piwStatic = IPropContainer_GetWidget(picProp, piwRadio, TRUE, FALSE);
}
}
RELEASEIF(picProp);
pszText = (AECHAR *)IValueModel_GetValue((IValueModel *)pEvent->pModel, &nLen);
if(piwStatic)
{
//do something
}
if(piwRadio)
{
//do something
}
}

Hi,
I am creating the list widget in which i set the list item as XYContainer and in XYContiner i added the Html Widget and i set the ISource in valuemodellistener with help of IDocModel_LoadSource.
The Problem is i am not able to view any data in the list widget.
but when i creating simple html Widget and attach the doc model to it its giving the o/p.
Is that limitation of list widget?
Regards,
Dinesh Bardepur.

I would probably recommend not using the HTML widget in a list item for the list wiget due to the EFS overhead loading the content. I would at least suggest using the list container. Can rich text be used instead? Why use the HTML widget in this case?

Hi,
It's a little tough reading the code, since there isn't any formatting. However, I think that the issue is due to the value model being used. The ValueModelListener() isn't using the ValueModel that is returned by IWIDGET_GetModel().
pFinal =(List_Data*)
IVALUEMODEL_GetValue(pMe->Item.pValueModel,pnLen);
This should be
pFinal =(List_Data*)
IVALUEMODEL_GetValue(pivm,pnLen);
