Setting text to a label and more

I never thought I would ask this question but how to I set text to a label properly? Both of these codes just work the first time it get called.

Code:

void FoodWindow::load()

{

    QString kcal, tmp;

    QList <QString> settings;

    int remaining;

    kcal.setNum(xml->getTodaysCalories());



    settings = xml->loadSettings();

    remaining = settings.takeLast().toInt() - kcal.toInt();

    tmp.setNum(remaining);



    if(remaining >= 0)

        lblCalories->setText("You have eaten " + kcal + " kcal today (" + tmp + " left). \nYour mean kcal/day is 2800 kcal ");

    else

        lblCalories->setText("You have eaten to much today. \nYour mean kcal/day is 2800 kcal ");

}

Code:

void ExerciseWindow::loadExercise(QList<QString> name)

{

    QDBusConnection::sessionBus().send(lock);

    QList <QString> tmp;

    QList<QString> settings = xml->loadSettings();

    QString lstReps[3];

    settings.removeLast();

    SEC = settings.takeLast().toInt();

    MIN = settings.takeLast().toInt();



    currentReps = settings.takeLast();

    lstReps[2] = settings.takeLast();

    lstReps[1] = settings.takeLast();

    lstReps[0] = settings.takeLast();



    if(currentReps == "Easy")

        REPS = lstReps[0].toInt();

    else if(currentReps == "Mid")

        REPS = lstReps[1].toInt();

    else

        REPS = lstReps[2].toInt();





    SET = settings.takeLast().toInt();



    vibrateActive = false; soundActive = false;

    if(settings.takeFirst() == "1")

        vibrateActive = true;

    if(settings.takeFirst() == "1")

        soundActive = true;



    currentExercise = name.first();

    tmp = xml->openEx(currentExercise);

    tmp.removeFirst();

    currentGroup = tmp.takeFirst();



    set = SET; reps = REPS; min = MIN; sec = SEC;

    strSet.setNum(SET); strReps.setNum(REPS); strMin.setNum(MIN);  strSec.setNum(SEC);

    label->setText("");

    label->setText(currentExercise + "\n Shake when done " + strReps + " reps");

    btnShake->setEnabled(true);

    //myThread->start(QThread::NormalPriority);

}

I am able to edit the label later but not on load wich is annoying. I have printed the text using qDebug() and its correct.

I also have problem when I went from a window to a dialog. After this code is called I guess the ui is still on-top but not showing, I can push the save button again.

Code:

void NewExerciseWindow::saveExercise()

{

    QString name = txtName->text();

    QString group = btnGroup->valueText();

    QString muscle = txtMuscle->text();

    QString info = txtHowTo->toPlainText();

    if(group == "Cardio")

        xml->saveCardio(name);

    else

        xml->saveEx(name,group,muscle,info);



    QMaemo5InformationBox::information(this, "Exercise saved.",

                                                QMaemo5InformationBox::DefaultTimeout);

    this->hide();

}

Edit: Forgot two questions about QListView. How do I disable the possibility to edit in the list manually and how do I highlight a row by knowing the name?

Thanks!
