QT: Passing QDialog as a object

I am new to QT. I have several QDialogs in my QT project. I have created a generic class to change the properties of widgets inside QDialogs. My generic class has a static method which will change the properties of widgets. 

void MyClass::setFontsizeToWidgets(float modValue, QObject obj)
{
    QFont f;
    float pointSize = 0.0;

    QList<QPushButton*> buttons = obj.findChildren<QPushButton*>();

    foreach ( QPushButton * button, buttons)
    {
        f = button->font();
        pointSize = f.pointSizeF();
        f.setPointSizeF(pointSize*modValue);
        button->setFont(f);
    }
}

Now my questions is, how to pass the QDialog as a object to the above static method from QDialog class? So that the static method will change the font size of the QPushButton(s) in the QDialog.

You can do it like this:

void MyClass::setFontsizeToWidgets(float modValue, QObject *obj)
{
    //do something 
}

void MyDialog::someFunction() //this is a function of your QDialog class
{
    MyClass::setFontsizeToWidgets(10, this);
}
