Adding text file contents to QListWidget



  • Hello,
    I've been trying to add text file content to QListWidget and have not been successful.
    I was wondering if someone could help?

    so far i have this in my constructor:
    @
    WordEditor::WordEditor(QWidget *parent) :
    QDialog(parent),
    ui(new Ui::WordEditor)
    {
    QFile f("data.txt");
    if (!f.open(QIODevice::ReadWrite | QIODevice::Text))
    return;
    ui->setupUi(this);
    QString fileContents = f.readAll();
    QStringList meh = fileContents.split('\n');
    ui->listWidget->addItems(QString(f.readAll()).split('\n'));
    qDebug() << fileContents << meh;
    f.close();
    }@

    my qDebug out put shows me:


    Starting F:\Projects\qt\build-SpellingBee-Desktop_Qt_5_0_2_MSVC2010_32bit-Debug\debug\SpellingBee...
    "ewe
    this
    is
    my
    test
    data" ("ewe", "this ", "is", "my", "test", "data")


    Also,
    I have another method that is supposed to add items to QListWidget but it seems to erase and replace items:
    @
    void WordEditor::on_btnAddWord_clicked()
    {
    QFile f("data.txt");
    ui->listWidget->insertItem(ui->listWidget->currentRow()+1, ui->lineEnterWord->text());
    if (!f.open(QIODevice::WriteOnly | QIODevice::Text))
    return;

        QTextStream out(&f);
        out << ui->lineEnterWord->text();
        f.close();
    

    }
    @

    Any guidance would be greatly appreciated.
    Thanks!!



  • Looks like i've managed to fix the loading issue with:
    @
    WordEditor::WordEditor(QWidget *parent) :
    QDialog(parent),
    ui(new Ui::WordEditor)
    {
    QFile f("data.txt");
    if (!f.open(QIODevice::ReadWrite | QIODevice::Text))
    return;
    ui->setupUi(this);
    QString fileContents = f.readAll();
    QListWidgetItem *itm = new QListWidgetItem;
    itm->setText(fileContents);
    ui->listWidget->insertItem(0,itm);
    f.close();
    }
    @
    I'm still trying to figure out the insert item replacement issue though.

    edit:
    this seems to just make a stringlist one big item. I'll work that out when i get back...
