Spliting string and displaying in Qtreewidget - c++

Question

My programming knowledge and experience is very poor. I am using this code block to open the desired file when clicked on a push button ;
QString filename = QFileDialog::getOpenFileName();
QFile file(filename);
if (!file.open(QIODevice::ReadOnly | QIODevice::Text))
return;
while (!file.atEnd())
{
QByteArray line = file.readLine();
processline(line);
}
And by this line i am showing it on QtextBrowser
void MainWindow::processline(QByteArray paramline)
{
ui->veri_cikis->append(paramline.constData());
}
The data on the file is like this
0;100;0
0;100;24
24;500;24
24;100;6
6;100;6
i have to split the datas by ";" mark and display them on a Qtreewidget columns. How do i do that ? And i have to show each first part on first column and second on second column and so. I have 3 columns in total

I think what you describe is better fit rather to a table view than a tree view. To parse your strings and split them by ';' character you can use QByteArray::split() function. Here is the sample code, that creates and populates table view with items that read from the file:
QFile file(filename);
if (!file.open(QIODevice::ReadOnly | QIODevice::Text))
return;
QTableWidget *table = new QTableWidget;
int row = 0;
while (!file.atEnd()) {
QByteArray line = file.readLine();
QList<QByteArray> tokens = line.split(';');
int column = 0;
row++;
foreach (QByteArray ba, tokens) {
QTableWidgetItem *item = new QTableWidgetItem(ba);
table->setItem(row, column++, item);
}
}
