automatically report when AC is plugged in or unplugged

So, some days ago, I was testing whether a plugpoint worked or not, and therefoe needed to constantly check the battery status, while the sighted person with me's focus was only on the icon.
So, of course the sighted person detected the change faster.
Therefore, it would have been good if NVDA would have automatically reported if AC had been plugged in or unplugged.
This is similar to the ticket about reporting changes in screen orientation.

Could be worth doing, but not as important as screen orientation because:

1. You can quickly check the battery status with one key command.
2. A change in screen orientation is clearly and immediately obvious to any user who isn't blind. A change in whether AC is connected is not so obvious even to sighted users unless they're looking at the icon.

I'd love to suggest you could just focus on the power icon in the notification area and it would tell you when the text changes, but unfortunately, it seems Windows doesn't bother to fire appropriate events when it updates, which is irritating.

So it turns out that @tspivey did this work in an add-on called powerNotify, that he wrote as a proof of concept, and then abandoned. He also implemented a beep when the screen is locked. This uses a message window (Like the one in core.py). I propose adding this functionality into core. (It's a minor issue, and I'd be happy to implement it).

Hi, if possible, can we combine this with screen orientation announcement? I thought there was a ticket somewhere. The reason for proposing this is in order to package them as a single PR, as the window can handle both if told to do so Thanks.

Hi joseph:
Do you have code to do this? If so, feel free to send it to me (Or I can send you tilers code) and we could merge them.

Hi,

@derekriemer and I have agreed to combine this and #4574 into a single PR package, using code from Tyler's implementation. Thanks.
