How to make a textbox update brightness level?

Question

I'm using Awesome window manager and have a textbox widget that I want to update with the current brightness level on an arbitrary interval of my choosing. Is there anyway to do this with Awesome and if so, how?

Answer 1

This is a great question. It's mostly covered by using the information on the widgets in awesome page. I havent set it up myself, but intend to use the same concepts for other functions. I'd use a combination of awful.widget.progressbar (brightness level is 0-100%). If you wanted to use your textbox, you can. add a signal to a timer widget that updates the text property of your textbox or use the set_value() if you want to use the Progressbar. Checkout the large list of lua extensions that are packaged as libraries. There may be one that already does what you want or something very similar.
