Detailed Description

This is the base class from which different authorization icon widget which actually do something should be derived. ABC for authorization icon widgets.

You can use these widgets to show that the user has (or doesn't have) the ability to do something, and why that is.

One of the most useful things you can do with this is connect authChanged(bool) to setEnabled(bool) for a widget to turn it on and off depending on the status of whatever it is you are monitoring.
