How to get QHelpIndexModel from QHelpEngine?

zither

Dear all,

I would like to get all index list from QHelpEngine. I tried like that but empty return.
What's wrong with that code?

@QHelpEngine *engine = new QHelpEngine(QString fileName);
engine->setupData();
qDebug()<<engine->filterAttributes; //return all filter attributes
qDebug()<<engine->indexModel()->stringList(); //empty string list return(error)@

Thanks

@ qDebug()<<Engine->indexModel()->isCreatingIndex(); // return true
connect(Engine->indexModel(),SIGNAL(indexCreated()),this,SLOT(slotIndexCreate())); //not connect@

Plz Help
Thanks

What's the output of the connect statement? Qt prints on stderr (or stdout) a message with a description of the problem if a connect fails.

No error message from connect statement. But no call to SLOT.
Is there any wrong with SIGNAL producer, Engine->indexModel()?
I can't get also
@qDebug()<<engine->indexModel()->stringList();@

Thanks a lot

Maybe a race condition: The help search indexe runs in a separate thread. It could be that the indexing has been finished after your call of isCreatingIndex() (that's why that one returns true) and before the connect statement finishes. That's why the emitted signal is not delivered.

So, how can I get indexModel from QHelpEngine?
I try like that but get nothing.
@Model = Engine->indexModel();
Widget = Engine->indexWidget();
newWidget->setModel(Model);
addWidget(Widget); // no data show
addWidget(newWidget); // no data show@

Thanks

zither

Sorry
@connect(Engine->indexModel(),SIGNAL(indexCreated()),this,SLOT(slotIndexCreate())); // connect
qDebug()<<Engine->indexModel()->stringList(); //empty "()" return@

Thanks

Does your help collection load in qt assistant?

No, I just don't load help collection in qt assistant.
I directly load like that.

@QHelpEngine *engine = new QHelpEngine(QString fileName);@

So, am I need to load help collection file first?

Thanks

You can check whether your help collection is prepared correctly by loading it into Qt Assistant. This way you make sure the data you try to load is sane.
