    '''
    Taurus Class that visualizes Synoptics drawn with the JDraw tool (by ESRF). It is equivalent to ATK Synoptic Player (Java).

    After initialization call setModel('/your/file.jdw') to parse the synoptic file and connect to controlled objects.

    Arguments to TaurusJDrawSynopticsView() creator are:

        - designMode; used by Qt Designer
        - updateMode; controls Qt Viewport refresh (disabled by default)
        - alias; a dictionary of name replacements to be applied on graphical objects
        - resizable: whether to allow resizing or not
        - panelClass: class object, class name or shell command to be shown when an object is clicked (None will show default panel, '' or 'noPanel' will disable it)

    TaurusJDrawSynopticsView and TaurusGraphicsScene signals/slots

    External events::

     Slot selectGraphicItem(const QString &) displays a selection
     mark around the TaurusGraphicsItem that matches the argument passed.

    Mouse Left-button events::

     Signal graphicItemSelected(QString) is triggered, passing the
     selected TaurusGraphicsItem.name() as argument.

    Mouse Right-button events::

     TaurusGraphicsItem.setContextMenu([(ActionName,ActionMethod(device_name))]
     allows to configure custom context menus for graphic items using a list
     of tuples. Empty tuples will insert separators in the menu.
