You should show a busy progressbar until the first progress() signal is received. The done() signal is emitted _before_ the result() signals of subclasses and should be used to hide and/or reset progress bars, not to learn of the end of the operation.

The result() signal of subclasses will still be emitted, though, and will carry the information that the operation was canceled. */ class Job : public TQObject { Q_OBJECT protected: Job( TQObject * parent, const char * name ); public: ~Job(); virtual void showErrorDialog( TQWidget * parent=0, const TQString & caption=TQString() ) const; virtual TQString auditLogAsHtml() const; virtual GpgME::Error auditLogError() const; bool isAuditLogSupported() const; public slots: virtual void slotCancel() = 0; signals: void progress( const TQString & what, int current, int total ); void done(); }; } #endif // __KLEO_JOB_H__
