Go 1.3 support #76

ildus commented 10 years ago

I updated Go to 1.3 release recently. I work in Mac OS X, Qt 5.3.1. I'm not sure it's related with go 1.3 or not, but error happens in qml goroutine:

This is a duplicate of #66, you are running qml.v0 which doesn't work on an OS which requires GUI operations to be performed on the main thread.

qml.v1 (in development) can guarantee (if started properly) that all gui operations are done on the main thread, but for now requires that you use git manually to install the proper branch.

Details for getting v1 to work on OS X are documented here: https://groups.google.com/forum/#!topic/go-qml/309B4MAS2dE
