kandi X-RAY | CadCanvas Summary
I will be adding a readme here. But for the time being your best way to learn what Cad Canvas is and how it works is to head over to the example and take a look at it’s source. Also sorry about some of the variable names.. I was learning ruby at the same time I was writing this and some of the ruby_variable_names may have bled over [ sad panda ]. A basic knowledge of JQuery is assummed by this README.

The binding in the Button is initialized in the
InitializeComponent()
method. At this point, the property is empty, and when you set a value to it, the binding cannot find out.

- Raise PropertyChanged in the property;
- If you set the property value once in the constructor, then set it immediately in the initializer. Make the property "Read Only". This way, in my opinion, is better.

I'm trying to create a cross-hair out of two lines on a WPF canvas.
I'm finding that when I initialize the lines they draw correctly. But when I update the coordinates of the lines using the mouse move event, the lines are not updating.
Why are the lines not updating when the coordinates of the point `currentMousePoint are updated?
