An Example of Go Application with a GUI Using lorca

I have looked all over the Googlesphere for a good example of a Go application that uses github.com/zserge/lorca. Especially an application that leverages HTML5's canvas object.

This example creates an application that illustrates:

• HTML 5 canvas drawing
• Buttons and lorca's function binding
• Golang event loop using select over multiple channels
• Pushing content (the current time) from server-side asynchronous events.

To Build

1. Make sure you have Chrome installed. You do have Chrome (or Chromium or Microsoft's Chrome variant), right?
2. Download the repository
3. run $ go build ./...
4. run $ ./lorca_example

Using HTML5 CSS, you can create multiple pages and toggle between them.

One aspect of this solution that I am not fully a fan of is the amount of raw HTML and Javascript that is required to implement a basic application. While embracing separation of concerns and MVC models are excellent objectives, it would be ideal to be able to be able to write an application in pure Go, and let Go libraries provide interfaces to HTML and Javascript through idiomatic Golang.
