 /**
  * This is a base class for scanning dialogs. You can derive from this class
  * and implement your own dialog. An implementation is available in
  * kdegraphics/libkscan.
  *
  * Application developers that wish to add scanning support to their program
  * can use the static method @p KScanDialog::getScanDialog() to get an instance
  * of the user's preferred scanning dialog.
  *
  * Typical usage looks like this (e.g. in a slotShowScanDialog() method):
  *
  * \code
  * if ( !m_scanDialog ) {
  *     m_scanDialog = KScanDialog::getScanDialog( this );
  *     if ( !m_scanDialog ) // no scanning support installed?
  *         return;
  *
  *     connect( m_scanDialog, SIGNAL( finalImage( const QImage&, int )),
  *              SLOT( slotScanned( const QImage&, int ) ));
  * }
  *
  * if ( m_scanDialog->setup() ) // only if scanner configured/available
  *     m_scanDialog->show();
  * \endcode
  *
  * This will create and show a non-modal scanning dialog. Connect to more
  * signals if you like.
  *
  * @short A baseclass and accessor for Scanning Dialogs

  * @deprecated since 5.0, use libksane instead
