 /**
  * @class KRegExpEditorInterface kregexpeditorinterface.h <KRegExpEditorInterface>
  *
  *  A graphical editor for regular expressions.
  *
  * @author Jesper K. Pedersen blackie@kde.org
  *
  * The actual editor is located in kdeutils, with an interface in
  * kdelibs. This means that it is a bit more complicated to create an
  * instance of the editor, but only a little bit more complicated.
  *
  * To check if kregexpeditor in kdeutils is installed and available use this line:
  *
  * \code
  * bool installed=!KServiceTypeTrader::self()->query("KRegExpEditor/KRegExpEditor").isEmpty();
  * \endcode
  *
  * The following is a template for what you need to do to create an instance of the
  * regular expression dialog:
  *
  * \code
  * QDialog *editorDialog = KPluginTrader::createInstanceFromQuery<QDialog>(QLatin1String("kregexpeditor"),
                                                                            QLatin1String("KRegExpEditor/KRegExpEditor"));
  * if ( editorDialog ) {
  *   // kdeutils was installed, so the dialog was found fetch the editor interface
  *   KRegExpEditorInterface *editor = static_cast<KRegExpEditorInterface *>( editorDialog->qt_cast( "KRegExpEditorInterface" ) );
  *   Q_ASSERT( editor ); // This should not fail!
  *
  *   // now use the editor.
  *   editor->setRegExp("^kde$");
  *
  *   // Finally exec the dialog
  *   editorDialog->exec();
  * }
  * else {
  *   // Don't offer the dialog.
  * }
  * \endcode
  *
  * Note: signals and slots must be connected to the editorDialog object, not to the editor object:
  * \code
  * connect( editorDialog, SIGNAL( canUndo( bool ) ), undoBut, SLOT( setEnabled( bool ) ) );
  * \endcode
  *
  * If you want to create an instance of the editor widget, i.e. not the
  * dialog, then you must do it in the following way:
  *
  * \code
  * QWidget *editorWidget =
  * KServiceTypeTrader::createInstanceFromQuery<QWidget>(
  *     "KRegExpEditor/KRegExpEditor", QString(), parent );
  * if ( editorWidget ) {
  *   // kdeutils was installed, so the widget was found fetch the editor interface
  *   KRegExpEditorInterface *editor = static_cast<KRegExpEditorInterface *>( editorWidget->qt_cast( "KRegExpEditorInterface" ) );
  *   Q_ASSERT( editor ); // This should not fail!
  *
  *   // now use the editor.
  *   editor->setRegExp("^kde$");
 
  *   // Finally insert the widget into the layout of its parent
  *   layout->addWidget( editorWidget );
  * }
  * else {
  *   // Don't offer the editor widget.
  * }
  * \endcode
  * @deprecated since 5.65 due to no functional implementation
