I'm looking to try and develop some simple indicators, for numlock/capslock and brigthness, etc. How would I go about creating indicators in python? Are there any tutorials that walk me through writing my first appindicator (like for apps in quickly)? Any easy solutions for starting like quickly templates?
You can find the page for writing app indicators here:
On that page you'll find links to examples in Python and the API documentation. The ubuntu-application template in Quickly should have examples on using appindicators. Good luck!
This link will teach you to create a basic new mail indicator in python+unity, which works with GMail. This will give you a solid grounding in the basic structure of an applet while providing a real-world (albeit simplistic) example that you can easily extend.
It's go through the final script piece by piece.
I think Writing indicators with Python, GIR and GTK3 ,as mentioned by @fossfreedom, covers how create indicators for Unity. (Read that 1st)
I'm using Ubuntu 14.04, Quickly 12.08.1 . This is demo for a complete working example build from a Quickly template.
