/**
* @ingroup main

* @short Generic configuration dialog that even works over component boundaries
*
* For more information see \ref KSettings.
*
* This class aims to standardize the use of configuration dialogs in KDE
* applications. Especially when using KParts and/or Plugins you face problems
* creating a consistent config dialog.
*
* To show a configuration dialog you only have to call the show method and be
* done with it. A code example:
*
* You initialize \p m_cfgdlg with
* \code
* m_cfgdlg = new Dialog( Dialog::Static, this );
* \endcode
* If you use a KPart that was not especially designed for your app you can use
* the second constructor:
* \code
* TQStringList kpartslist;
* for( all my kparts )
* kpartslist += m_mypart->instance().instanceName();
* m_cfgdlg = new Dialog( kpartslist, this );
* \endcode
* and the action for the config dialog is connected to the show slot:
* \code
* KStdAction::preferences( m_cfgdlg, TQT_SLOT( show() ), actionCollection() );
* \endcode
*
* If you need to be informed when the config was changed and applied in the
* dialog you might want to take a look at Dispatcher.
*
* For more information see \ref KSettings.
