Freeing Memory for QPushButtons with QMessageBox

I've instantiated a QMessageBox and added a couple of buttons to it like so:

QMessageBox message;
cancelButton = message.addButton(tr("Cancel"), QMessageBox::RejectRole);
okButton = message.addButton(tr("OK"), QMessageBox::ActionRole);

Is it necessary to call the destructors for each pushbutton before exiting, or does the QMessageBox destructor take care of everything?

No.

When parent objects are deleted they delete their children. So the buttons will be deleted when 'message' is.
