In the String the path is right, but it doesn't put strings in my table . No Error or Warnings. When I do this for example:
meinModel->setData(filename, filename);
it views the Strings : E:/test.txt
I have a QTableView and a QAbstractTableModel.
void View::OpenFileButtonClicked()
{
QString filename = QFileDialog::getOpenFileName(0, QString(), QString()
,tr("Data (*.txt)"));
fileMy = new QFile(filename);
QTextStream stream (&*fileMy);
while (!stream.atEnd())
{
QString line = stream.readLine();
QStringList list = line.split(",");
QString firststring;
firststring = (list.first());
QString secondstring;
secondstring = (list.last());
// Strings are sent to Model which view they in my tableview.
meinModel->setData(firststring, secondstring);
}
}
Strange, because this works:
void View::FileButtonClicked()
{
QString fileName;
if (txtPfad->text().length() > 0 )
{
fileMy = new QFile(txtPfad->text());
}
else
{ fileMy = new QFile("E:\\test.txt"); }
if (!fileMy->open(QIODevice::ReadOnly | QIODevice::Text))
{
QMessageBox::information(this, tr("ERROR"), tr("Daten konnten icht eingelesen werden"));
return;
}
QTextStream stream (&*fileMy);
while (!stream.atEnd())
{
QString line = stream.readLine();
QStringList list = line.split(",");
QString firststring;
firststring = (list.first());
QString secondstring;
secondstring = (list.last());
meinModel->setData(firststring, secondstring);
}
}
You missed opening of a file in OpenFileButtonClicked
:
if (!fileMy->open(QIODevice::ReadOnly | QIODevice::Text))
{
QMessageBox::information(this, tr("ERROR"), tr("Daten konnten icht eingelesen werden"));
return;
}
