[gtkmm] Automatically destroying a dialog

[Marc Canaleta <mcanaleta telefonica net>]

Hi,

I want a dialog to be deleted when it is closed (similar to widgets 
created with manage()). The problem is that it isn't modal and I can 
have various of them simultanelly, so I must create it using new, and I 
don't know where to delete it when it is closed.

I thinked using a thread for each dialog, is it the correct solution?

Thanks.
