QHelpEngine how-to

Woody

[SOLVED]

I don't know it is appropriate to ask the question here (if not please say so i'll start a new topic)

I have the problem with an error, it happens when calling the setCollectionFile() funtion of QHelpEngine.

@void HelperWindow::initialize()
{
HelperWindow::setWindowFlags(Qt::WindowStaysOnTopHint);

m_helpEngine->setCollectionFile&#40;QApplication::applicationDirPath(&#41; + "doc/athleticsmanager.qhc"&#41;;
m_helpEngine->setupData();

}@

When i look deeper into the code behind this function i get this:
@if (fileName == collectionFile())
return;@

It's in the collectionFile() function, that only does
@return d->collectionHandler->collectionFile();@

, where i get "Segmentation Fault"

I dont really know what to do now, is there someone who can help me with this problem?

I encounter quietly the same problem:

I am able to load my "doc.qhc" using the Qt Assistant and the content widget contains my documentation sections
my "doc.qhc" and "doc.qch" are located in the same directory
when building my help widget (see code below), no error is encountered
my content widget is empty (the content model has 0 rows)
@
QFileInfo info("doc.qhc");
if (info.exists() == false)
{
qDebug << "Help file does not exist";
}
m_engine = new QHelpEngine(info.absoluteFilePath());
if (m_engine->setupData() == false)
{
qDebug << "Help engine setup failed";
}
QGridLayout* layout = new QGridLayout;
QSplitter* helpPanel = new QSplitter(Qt::Horizontal);
helpPanel->insertWidget(0, m_engine->contentWidget());
m_webView = new QWebView;
helpPanel->insertWidget(1, m_webView);
layout->addWidget(helpPanel, 0, 0);
setLayout(layout);
connect(m_engine->contentWidget(), SIGNAL(linkActivated(QUrl)), SLOT(SetHelpSource(QUrl)));
qDebug() << m_engine->contentModel()->rowCount());

I had a look on the Qt Assistant source code and it seems to do the same thing to load a collection file...or I missed something.
Any suggestion?
Thanks in advance for your help
