Transparent widget and their children widgets

[naturalpsychic]

Hi I have a transparent dialog box (windowOpacity = 0.5) and I have another dialog box who is (and has to be) child of this dialog.

Is this possible to have full opacity just for that control? I know if I don't make it as child of the previous dialog, it does have full opacity but the reason why i want that to be child is because the parent is in full screen mode and I don't want any bars (for example unity bar in ubuntu) to display when modal dialog is shown as "orphan". I have tried following:

//CODE IN PARENT CONSTRUCTOR
    dlgChild = new Dialog(this);
    dlgChild->setModal(true);
    dlgChild->setWindowFlags(Qt::WindowStaysOnTopHint);
    dlgChild->setWindowFlags(Qt::FramelessWindowHint);
    for (int i = 0;  i < dlgChild->children().size(); i++) {
        QObject* child = dlgChild->children().at(i);
        static_cast<QWidget*>(child)->setWindowOpacity(1);
    }
    dlgChild->setWindowOpacity(1);
    dlgChild->show();

//CODE IN PARENT CONSTRUCTOR
    dlgChild = new Dialog(this);
    dlgChild->setModal(true);
    dlgChild->setWindowFlags(Qt::WindowStaysOnTopHint);
    dlgChild->setWindowFlags(Qt::FramelessWindowHint);
    for (int i = 0;  i < dlgChild->children().size(); i++) {
        QObject* child = dlgChild->children().at(i);
        static_cast<QWidget*>(child)->setWindowOpacity(1);
    }
    dlgChild->setWindowOpacity(1);
    dlgChild->show();

Anyone on this please?

Opacity is inherited. If you make a widget semi-transparent, its children will be semi-transparent too. I suggest you look for an alternative approach to your problem.

Can you suggest any? What would you do if you were me?

I don't know what your intention is so it is hard to suggest anything.
