/**
* @ingroup main
* @ingroup findreplace
* @brief A generic "find" dialog.
*
* @author S.R.Haque <srhaque@iee.org>
*
* \b Detail:
*
* This widget inherits from KDialogBase and implements
* the following additional functionalities: a find string
* object and an area for a user-defined widget to extend the dialog.
*
* \b Example:
*
* To use the basic modal find dialog, and then run the search:
*
* \code
* KFindDialog dlg(....)
* if ( dlg.exec() != TQDialog::Accepted )
* return;
*
* // proceed with KFind from here
* \endcode
*
* To create a non-modal find dialog:
* \code
* if ( m_findDia )
* KWin::setActiveWindow( m_findDia->winId() );
* else
* {
* m_findDia = new KFindDialog(false,...);
* connect( m_findDia, TQT_SIGNAL(okClicked()), this, TQT_SLOT(findTextNext()) );
* }
* \endcode
* Don't forget to delete and reset m_findDia when closed.
* (But do NOT delete your KFind object at that point, it's needed for "Find Next")
*
* To use your own extensions: see findExtension().
*
