Get Drawing Working about sandify

[jamesd256]

Could you provide a link to the example of react canvas you found? Was it this one?. I found some interesting information about the subject here. There is a react-canvas out there which is not really an HTML 5 canvas, so might be misleading.

Can you help me with a basic understanding of why react is incompatible with HTML5 canvas? I notice in your TurtleCanvas.js, you use the following to obtain the context:

var context = ReactDOM.findDOMNode(this).getContext('2d');

Is your concern about getting access to the context? While looking into how to do this I came across this post, which offers a couple of different ways to obtain canvas context access.

It seems to me that react + canvas should function fine, but maybe you feel it's not the correct approach for some reason. The turtle_port branch contains turtle.js ported to be a react component, and this can be adapted to output either gcode or raw vertices.

Sorry, this issue is out of date. I think it should probably be closed.

The example I found was this: http://jsfiddle.net/JMZc5/1/ but it didn't work until I did the ReactDOM.findDOMNode call.

I'm currently happy enough with the drawing that we have in MachinePreview.js. If using 'react-canvas' is more right/better/more flexible, then I'm fine with that too.

I'll open another issue where we can integrate turtle.
