metaObject()->className() doesn't find QLabel

[mar0029]

Hello!

I am using the following code to find all QLayouts within a main layout and then all widgets within those layouts.

if(!allSubLayouts.empty())
{
    int size = allSubLayouts.size();
    for(int i = 0; i < size; i ++)  // this loop hides all of the layouts that are currently present. If there are no layouts, nothing happens
    {
        for(int j = 0; j < allSubLayouts.at(i)->count(); ++j)
        {

            QWidget *w = allSubLayouts.at(i)->itemAt(j)->widget();
            if(w != NULL)
            {
                qDebug() << "The className of the object is " ;
                qDebug() << allSubLayouts.at(i)->itemAt(j)->widget()->metaObject()->className();

                w->setVisible(false);
                //delete w;
            }
        }
    }

When I run the code, everything except the QLabel classnames are displayed in the qDebug statement.

Why doesn't widget()->metaObject()->className(); produce QLabels?

It seems okay, but have you tried something simpler like QObject::findChildren?

QList<QWidget *> items = findChildren<QWidget *>();
foreach (QWidget * item, items)
    qDebug() << item->metaObject()->className();

Kind regards.
