I want to draw a rectangle around a group of rectangular adjacent components that are in a Canvas. I can't seem to find the right component to do this, or I am just not doing it properly. I tried using a Canvas inside the Canvas with the inner borders set and adding the components to the inner Canvas and placing the inner Canvas at the location of the components it now contains, but it doesn't show up. I also tried a transparent Canvas with backgroundAlpha set to 0. Canvas is probably not the proper component to do this with. Is there an easier way?
