Is there a callback function in Julia Gtk that gives the mouse position when clicked on a Canvas?

There’s an example in the [docs](https://juliagraphics.github.io/Gtk.jl/latest/manual/canvas.html), you can access the mouse position with `event.x` and `event.y`. That said it doesn’t work on my computer (but it’s probably because I have the new Cairo binaries).

Hi, Jonathan, oddly, it does work on my Mac, without  
using Cairo. So once again thanks for your help, for which I’m  
much indebted!
