"In proper place, of course: QDialog *dialog = new QDialog; dialog->show(); int ret = app.exec(); delete dialog; return ret; But in fact it's much easier to allocate dialog statically."
Hi Daniil, the example only contains a main function, there is no need for that delete, its quite redundant as the heap is cleared anyways after the return and app exits in the example ,is it not ?It would have been necessary had this been allocated in some custom class. cheerskrk969 ----- Original Message ----- From: Daniil Ivanov Sent: 06/01/10 11:34 AM To: Ram Kurvakat Subject: Re: QT4.6 with PR1.2 has introduced issues On Tue, Jun 1, 2010 at 1:16 PM, Ram Kurvakat <rkma...@gmx.com> wrote: > > ----- Original Message ----- > > From: Daniil Ivanov > > Sent: 06/01/10 10:44 AM > > To: Ram Kurvakat > > Subject: Re: QT4.6 with PR1.2 has introduced issues > > On Tue, Jun 1, 2010 at 12:00 PM, Ram Kurvakat <rkma...@gmx.com> wrote: > > > -- > Sent from my Nokia N900 > > ----- Original message ----- >> Hi Ram! >> >>> Could you please post this questions to FN DiBo? > A > Hi Daniil, yes > of course i can. > I was asked for examples here so i replied. > FN DiBo = > forum nokia discussion board ?
