Modal windows/dialogs

[marcusolsson]

tui-go should support modal windows that ask for confirmation or other user input. This would be painted on top of the application and will need some design discussions on how to support basic compositing.

Example:

┌──────────────┐
│ Really quit? │
│              │
│ OK    Cancel │
└──────────────┘

Agree (from previous discussion) about everything being keyboard friendly. I think the easiest way to support this feature is just having layers where all keyboard input is sent to the current layer. Regarding rendering, initially a painters algorithm would be easiest, then we can look at optimising this if needed.

[marcusolsson]

I agree that would probably be a great place to start 👍

Maybe add two types of modals. Full width as well as those need to just stay in the center.

any updates on this request?

[marcusolsson]

Unfortunately not. I've had limited time to work on tui lately and have been prioritizing bugs. It would be really helpful if you wanted to share your use case and thoughts on how you'd expect the API to look.

@Syleron Pushed some work-in-progress of this in #103. If you have the time, let me know if this would work for you!

@marcusolsson Thank you! I will have a closer look and get back to you.
