Repainting/Refreshing Layout after one QWidget * has changed

[jacek]

You only change the body variable. Qt still has a pointer to the old widget. See QStackedWidget and QStackedLayout. Also don't forget to show the new widget.

Is there a way to tell QT to use the pointer on the new widget instead of the pointer of the old one ?

Alternatively is it possible to delete the entire layout and create a new one ?

This seems to work:

void 
DriverView::refreshDriverView() {
    body->hide();
    mainLayout->removeWidget(body);
    body = driverFactory()->driverUserInterface(driverFactory()->currentDriver());
    mainLayout->addWidget(body);
    body->show();
}

void 
DriverView::refreshDriverView() {
    body->hide();
    mainLayout->removeWidget(body);
    body = driverFactory()->driverUserInterface(driverFactory()->currentDriver());
    mainLayout->addWidget(body);
    body->show();
}

To copy to clipboard, switch view to plain text mode 

Is there anything that speeks against this ?

Where do you get rid of unused widgets?
