QPrinter - How to print a selected .txt file



  • Hi All,

    I've been doing research on QPrinter/QPrintDialog/QPainter and I am getting extremely confused. A lot of the code that I am reading doesn't really pertain to me because they are printing directly from the GUI widgets (ui->textedit->print()).

    Here is what I have so far on my code....

    void MainGui::on_actionPrint_Telemetry_triggered()
    {
        QPrinter printer;
    
        QPrintDialog dialogp(&printer, this);
        dialogp.setWindowTitle(tr("Print Document"));
    
        if (dialogp.exec() != QDialog::Accepted)
        {
            return;
        }
    }
    

    So, I would like to be able to have the user choose the file that they want to print. I already have a save function that is taking the data that I have and saving it to a .txt file. I'm sure I am just way overthinking this, but any help is appreciated!!

    Thanks All,
    Derek

    Hi
    The easy way would to use
    http://doc.qt.io/qt-5/qtextdocument.html
    as it can directly print to printer object.
    http://doc.qt.io/qt-5/qtextdocument.html#print

    there is also the option of drawing the texts yourself but i get the feeling you just want to print
    the text document as is ?



  • Hey @mrjj ,

    Thanks for your quick response! Yay, I can print!

    And you are correct! I do just want to print :D

    Thanks again for all of your help! This worked perfectly!!
