-----------------
.. class:: FormTool

    Base class: :class:`~dip.shell.BaseManagedModelTool`

    The FormTool class is a :term:`tool` that uses an automatically

    :term:`managed model`.

    .. attribute:: area = Str()

        The identifier of the area where the view should be placed.

    .. attribute:: controller_factory = Callable()

        The controller factory.  This must return an object that implements or
        can be adapted to the :class:`~dip.ui.IController` interface.

    .. attribute:: model_type = Instance(type)

        The type of model that the tool can handle.

    .. attribute:: view_factory = Instance(ViewFactory)

        The factory used to create the tool's views.

    .. method:: FormTool.create_views(model)

        Create the views for a managed model.
        
        :param model:
            is the model.
        :return:
            the list of views.

    .. method:: FormTool.handles(model)

        Check if the tool can handle a particular model.
        
        :param model:
            is the model.
        :return:
            ``True`` if a tool can handle the model.
