# Battery widget

Simple and easy-to-install widget for Awesome Window Manager.

This widget consists of:

 - an icon which shows the battery level:
 ![Battery Widget](./bat-wid-1.png)
 - a pop-up window, which shows up when you hover over an icon:
 ![Battery Widget](./bat-wid-2.png)
 Alternatively you can use a tooltip (check the code):
 ![Battery Widget](./bat-wid-22.png)
 - a pop-up warning message which appears on bottom right corner when battery level is less that 15% (you can get the image [here](https://vk.com/images/stickers/1933/512.png)):
