Is the sub window containing the widget the active MDI sub window or not? The focus only visibly changes in the active sub window although it has changed in the other sub-windows too. Does this help?

#include <QtGui>
 
class MyWidget: public QWidget 
{
    Q_OBJECT
public:
    MyWidget(QWidget *p = 0): QWidget(p) {
        edit1 = new QLineEdit(this); 
        edit2 = new QLineEdit(this);
 
        QVBoxLayout *layout = new QVBoxLayout;
        layout->addWidget(edit1);
        layout->addWidget(edit2);
 
        setLayout(layout);
        edit1->setFocus();
 
        QTimer::singleShot(5000, edit2, SLOT(setFocus()));  // switch focus in 5 seconds
    }
private:
    QLineEdit *edit1;
    QLineEdit *edit2;
};
 
int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
 
    QMdiArea m;
    m.addSubWindow(new MyWidget);
    m.addSubWindow(new MyWidget);
    m.show();
    return app.exec();
}
#include "main.moc"

#include <QtGui>

class MyWidget: public QWidget 
{
    Q_OBJECT
public:
    MyWidget(QWidget *p = 0): QWidget(p) {
        edit1 = new QLineEdit(this); 
        edit2 = new QLineEdit(this);

        QVBoxLayout *layout = new QVBoxLayout;
        layout->addWidget(edit1);
        layout->addWidget(edit2);

        setLayout(layout);
        edit1->setFocus();

        QTimer::singleShot(5000, edit2, SLOT(setFocus()));  // switch focus in 5 seconds
    }
private:
    QLineEdit *edit1;
    QLineEdit *edit2;
};

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    QMdiArea m;
    m.addSubWindow(new MyWidget);
    m.addSubWindow(new MyWidget);
    m.show();
    return app.exec();
}
#include "main.moc"

Hi! Thks for your attentation.

This command:

QTimer::singleShot(5000, edit2, SLOT(setFocus()));

Worked, but I think that this is a palliative, at least to me, but resolved my problem.

Thks another time.

Hugs.

The single shot timer was only there to provide something to change the focus in the example and demonstrate that focus does move. It doesn't fix any problem.
