[Qt-interest] Problems with `password dialog' (Detailed)

[Aaron Lewis]

Here's some more information:
   
  Actually i'm writing a Mysql Front End , when user triggered the
`Connection' action ,
 
  I'd like to show up a new Dialog , and let user type in informations
(kinds of username , passwd , hostname e.g)

  When she clicked on some button (e.g Yes) , dialog is closed ,  data
format is checked (isValid)
   then these information are transfered back to MainWindow (class qsqlcc)

  Now i'll be able to make connection between my program and mysql server

That's what i'm doing ..

Appreciate your help ;-)
