Can a ROI shape (ie. a Rectangle made by drawRectangle()) be a property of a class?

I am trying to associate a ROI drawn on an image with some other data in an app. So, I made a user defined class "device" that has several properties (a "tag" (the name of the device) and a "shape" (the ROI highlighting the device on an image).

When I try to use the class definition below, I get an error define the shape property:

Error defining property 'shape' of class 'device'. Class named 'Rectangle' is undefined or does not support property

validation. Classes that do not support property validation include Java, COM classes, and MATLAB classes that do not

use the classdef keyword.

See my class definition here:

classdef device
    properties
        tag     string
        shape   Rectangle
    end
    methods
    end
end

You need to specify the complete class name:

classdef device
    properties
        tag     string
        shape   images.roi.Rectangle
    end
    methods
    end
end

thought I did this at some point but probably missed something -- this worked.

Thank you! :)
