Delete/Close Dialog correct?

[kei]

Hi,
i have two question:

First i have the following code (from a example) and i'm not sure why this works:

Dialog *d = new Dialog(this);
d->deleteLater();
d->exec();
 
d->getSomething();

Dialog *d = new Dialog(this);
d->deleteLater();
d->exec();

d->getSomething();

To copy to clipboard, switch view to plain text mode 

I thought that deleteLater() will remove d after leaving the dialog, but the methode getSomething() still works I'm sure its only a little misunderstanding. Could you explain me this?

Second i leave this dialog with a button which is connected to the dialog's close() slot. Is this the right way?

greetings,
kei
