    Default How to use focusInEvent method of QWidget by inheriting QTabWidget?

    Hello,

    I'm trying as shown below,
    We already have this,
    Qt Code:
    1. class Q_WIDGETS_EXPORT QWidget : public QObject, public QPaintDevice
    2. {
    3. //Standard Class
    4. protected:
    5. virtual void focusInEvent(QFocusEvent *event);
    6. virtual void focusOutEvent(QFocusEvent *event);
    7. }
    8. class Q_WIDGETS_EXPORT QTabWidget : public QWidget
    9. {
    10. //Standard Class
    11. }
    To copy to clipboard, switch view to plain text mode 

    Now below, I'm trying to access virtual methods from QWidget, but I'm unable to do that, may be I'm missing some simple basics behind it.
    Qt Code:
    1. class MyWidget : public QTabWidget
    2. {
    3. Q_OBJECT
    4. public:
    5. virtual void focusInEvent(QFocusEvent *event);
    6. virtual void focusOutEvent(QFocusEvent *event);
    7. }
    8. void MyWidget::focusInEvent(QFocusEvent *event)
    9. {
    10. qDebug()<<"focusInEvent";
    11.  
    12. QWidget::focusInEvent(event);
    13. }
    14.  
    15. void MyWidget::focusOutEvent(QFocusEvent *event)
    16. {
    17. qDebug()<<"focusOutEvent";
    18. QWidget::focusOutEvent(event);
    19. }
    To copy to clipboard, switch view to plain text mode 

    I can access virtual methods from QTabWidget but not from QWidget, please give me suggestions on what I'm mistaking here?
    Or its protected, that why I'm unable to access it, is there any way to access such protected methods?
    Thanks
