If we overloading of QDialog, we should avoiding using the exec() ?

[cyberpunker]

I thind most of Qter know these three articles:

• Unpredictable exec()
• QtQuarterly30 : New Ways of Using Dialogs
• How to crash (almost) every Qt/KDE Application and how to fix it

It is seems that the exec() to be a little evil . So , If we overloading of QDialog, we should avoiding using the exec() ?
