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
