Detailed Description

A password input dialog.

This dialog asks the user to enter a new password.

The password has to be entered twice to check if the passwords match. A hint about the strength of the entered password is also shown.

Usage Exemple

Asynchronous

  KNewPasswordDialog *dlg = new KNewPasswordDialog( parent );
  dlg->setPrompt( i18n( "Enter a password" ) );
  connect( dlg, SIGNAL( newPassword(QString) )  , this, SLOT( setPassword(QString) ) );
  connect( dlg, SIGNAL( rejected() )  , this, SLOT( slotCancel() ) );
  dlg->show();

Synchronous

  KNewPasswordDialog dlg( parent );
  dlg.setPrompt( i18n( "Enter a password" ) );
  if( dlg.exec() )
      setPassword( dlg.password() );
