V2: TextField numeric input not working on non-Windows platforms about terminal.gui HOT 5 OPEN

@cjlotz can you please test the PR #3542, on Linux and macOS to see if it working better. On macOS, for the Alt key to work at all, you need to change the following configuration in Terminal. Thanks.

Terminal > Preferences > Profiles > Keyboard and just check Use Option as Meta key

@BDisp I can confirm that the fixes work on my Mac and also in Ubuntu 22.04 running in WSL on Windows 11.

This sounds like a bug. But having more information to diagnose would help.

Can you check whether NumLock or Scroll Lock is down when trying to type. Sometimes that makes a difference (although it really shouldn't).

One thing that would help is to know exactly what the keycode is that is being ignored.

You can trap all key events at application level with a global listener (see below) and then look at e in the debugger. If you could provide a screenshot of what that is showing on the affected OS that would be great.

        Application.KeyDown += (s, e) =>
        {
            // Break point here
        };

Another way is to run the 'Keys' scenario in UICatalog on the machines, it logs all key strokes.

@tznind Thanks for the reply.

Following your suggestion, I added a status bar item that logs the key code. On Windows 11 when I execute this, I see D1, D2... for the digits. On Linux (Ubuntu 22.04 running in WSL on Windows 11), the same key codes are logged as 17, 18, 19...

I wasn't sure if running in WSL might be causing the issue, so I compiled this on my Mac as well. When executing on the Mac I see the same behaviour, i.e. the digits are logged as 17,18,19. On the Mac I have some additional issues with some other key codes as well. For example, Backspace is logged as 95 on Mac, but interpreted correctly on Linux and Windows.

Thoughts?

I've now also verified this with the Keys example on the Mac. Running the Keys example for the develop branch works fine, but running the Keys example from the v2_develop branch does not work for digits and some other keys.
