QPixmap::graWidget always getting null!

[doijunior]

Hello I have some widgets that I need to save into a img, but I had some problems even before in the pixmap.
The widget is a QCalendarWidget derived class, but after had problems I tried doing this:

QCalendarWidget *c = new QCalendarWidget();
    QPixmap pix;
    pix.grabWidget(c);
    if(pix.isNull()) qDebug("fail")

QCalendarWidget *c = new QCalendarWidget();
    QPixmap pix;
    pix.grabWidget(c);
    if(pix.isNull()) qDebug("fail")

To copy to clipboard, switch view to plain text mode 

Myclass and even QCalendarWIdget, QWidget, etc.. always fail
I need to do something else inside the widget class to grab it? (I am not calling it graWidget on the paintEvent() )

grabWidget() is a static function, so you have to call it like that:

pix = QPixmap::grabWidget(c);

pix = QPixmap::grabWidget(c);

To copy to clipboard, switch view to plain text mode
