  This class realizes the moving of guides and the moving of the ruler origin

class SCRIBUS_API RulerGesture : public CanvasGesture
        enum Mode { HORIZONTAL, VERTICAL, ORIGIN };
        RulerGesture (ScribusView* view, Mode mode) :
                CanvasGesture(view), m_ScMW(m_view->m_ScMW), m_mode(mode), m_haveGuide(false), m_haveCursor(false), m_xy(0,0) {};

                Prepares the gesture for 'mode' without using an existing guide. If 'mode' is HORIZONTAL
                or VERTICAL, a new guide will be created when the mouse is moved over a page.

        void prepare(Mode mode);
        void clear();
        virtual void drawControls(QPainter* p);
        virtual void activate(bool);
        virtual void deactivate(bool);
        virtual void mouseReleaseEvent(QMouseEvent *m);
        virtual void mouseMoveEvent(QMouseEvent *m);
          This method should be called when the mousebutton is pressed.
          If there's a moveable guide near this position, it prepares the gesture for moving this guide.

        virtual void mousePressEvent(QMouseEvent *m);
        Mode getMode() { return m_mode; }
                Use this to test if there's a moveable guide near this position.
                It prepares the gesture for moving this guide.

        bool mouseHitsGuide(FPoint mousePointDoc);
          It tests for a guide near position, that guide being moveable or not.
          If the test results in success, emits guideInfo;

        void mouseSelectGuide(QMouseEvent *m);
        ScribusMainWindow* m_ScMW;
