Program crash with ui->listView->setModel()

htmlboss

Noob question :D
I am trying to populate a QListView with the data from a StringList, however the program crashes if I un-comment the last line. I suspect it's a wayward pointer (probably ui->listView).

QStringList fileList;

            // Remove file extension and absolute path from string respectively (to be replaced by QFileInfo)
            QString filenameRaw = it.next();
            QString filenameNoExt = filenameRaw.split(".", QString::SkipEmptyParts).at(0);
            QString filename = filenameNoExt.split("/", QString::SkipEmptyParts).at(3);
            qDebug() << filename;

            fileList << filename;

            QStringListModel *model = new QStringListModel();
            model->setStringList(fileList);
            qDebug() << fileList;
            
            //Problematic Line (everything works as intended until here)
           ui->listView->setModel(model);

Hi and welcome
I tried your code in a new project with a QListView on the form
and got abfdef and no crashes.
So where do you call your code?
its after setupUI, yes?

void MainWindow::on_pushButton_released() {
  QStringList fileList;
  fileList << "a" << "b" << "c"<< "d"<< "f";
  QStringListModel* model = new QStringListModel();
  model->setStringList(fileList);
   //Problematic Line (everything works as intended until here)
  ui->listView->setModel(model);
}

ROFL! The function call was before setupUI ^.^ I'll see if that fixes it :P

Edit: Yep! That was the problem :P My bad! Thanks for the help!
