c++ - Freeing Memory for QPushButtons with QMessageBox -


i've instantiated qmessagebox , added couple of buttons so:

qmessagebox message; cancelbutton = message.addbutton(tr("cancel"), qmessagebox::rejectrole); okbutton = message.addbutton(tr("ok"), qmessagebox::actionrole);

is necessary call destructors each pushbutton before exiting, or qmessagebox destructor take care of everything?

no.

when parent objects deleted delete children. buttons deleted when 'message' is.
