How to manipulate a text in QTextEdit

[Ryan111]

That's not really related to QTextEdit, just basic string manipulation.

Thanks!
that works but not correctly! look:



as you can see, after several insert, it cannot put ",0x" string anymore. why? the code is this:

void MainWindow::on_pushButton_clicked()
{
    QString txt = ui->textEdit->toPlainText();
 
    for (quint32 t = 0 ; t <= (txt.size()/8) ; t = t+11 )
    {
        txt.insert( t , QString(",0x"));
 
    }
 
    ui->textEdit->setText(txt);
}

void MainWindow::on_pushButton_clicked()
{
    QString txt = ui->textEdit->toPlainText();

    for (quint32 t = 0 ; t <= (txt.size()/8) ; t = t+11 )
    {
        txt.insert( t , QString(",0x"));

    }

    ui->textEdit->setText(txt);
}

To copy to clipboard, switch view to plain text mode
