Getting QHelpContentWidget QUrl with Single-Click

polluxpolaris

The linkActivated() signal of QHelpContentWidget only triggers on a double-click but I want to trigger on a single-click.

I am able to successfully trigger a slot on clicked() and selectionChanged(int index) but I don't know how to get the QUrl from the QHelpContentWidget with the index.

I also tried helpEngine->contentWidget()->setEditTriggers(QAbstractItemView::CurrentChanged); without success.

Does anyone know how to get a QUrl from QHelpContentWidget using an int index?

I learned 2 things:

I need to access the QUrl directly from QHelpEngine, not its QHelpContentWidget.
I cannot access QHelpEngine content using a int index, I must use a QModelIndex.

Here's my current solution:

QObject::connect(helpEngine->contentWidget(),QHelpContentWidget::clicked,this,MainWindow::testSlot);

void MainWindow::testSlot(){
QModelIndex testIndex = helpEngine->contentWidget()->currentIndex();
QHelpContentItem *item = helpEngine->contentModel()->contentItemAt(testIndex);
QUrl testUrl = item->url();
textViewer->setSource(testUrl);
return;
}

Here's a better way that passes the clicked index instead of checking for the currently selected index:

QObject::connect(helpEngine->contentWidget(),QHelpIndexWidget::clicked,this,HelpMenu::onContentClick);

void HelpMenu::onContentClick(QModelIndex testIndex){

    QVariant v = helpEngine->indexModel()->data(testIndex, Qt::DisplayRole);
    QMap<QString,QUrl> item = helpEngine->indexModel()->linksForKeyword(v.toString());

    textViewer->setSource(item.constBegin().value());
    return;

}

Thanks for this. It was really helpful.

I couldn't get it to work with your syntax for connecting the signal and slot but the code below worked for me. Not sure if something has changed over the years - I am v new to Qt.

connect(contentWidget, SIGNAL(clicked(QModelIndex)), this, SLOT(testSlot()));

void HelpWindow::testSlot()
{
    QModelIndex testIndex = mpHelpEngine->contentWidget()->currentIndex();
    QHelpContentItem *item = mpHelpEngine->contentModel()->contentItemAt(testIndex);
    QUrl testUrl = item->url();
    ui->textBrowser->setSource(testUrl);
    return;
}

Of course the testSlot function needs to be added to the Slots in the .h file.

Hope this helps someone out there
