Detailed Description

A password input dialog.

This dialog asks the user to enter a password. The functions you're probably interested in are the static methods, getPassword() and getNewPassword().

Usage example

 QCString password;
 int result = KPasswordDialog::getPassword(password, i18n("Prompt message"));
 if (result == KPasswordDialog::Accepted)
     use(password);

Security notes:

Keeping passwords in memory can be a potential security hole. You should handle this situation with care.
