|
|
* @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 tdepartslist;
|
|
* for( all my tdeparts )
|
|
* tdepartslist += m_mypart->instance().instanceName();
|
|
* m_cfgdlg = new Dialog( tdepartslist, this );
|
|
* \endcode
|
|
* and the action for the config dialog is connected to the show slot:
|
|
* \code
|
|
* KStdAction::preferences( m_cfgdlg, TQ_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.
|
|
*
