Original Pull Request: https://github.com/microsoft/terminal/pull/12526

State: closed
Merged: Yes

Window shenanigans, part the first:

This PR enables terminals to tell ConPTY what the owning window for the pseudo window should be. This allows thigs like MessageBoxes created by console applications to work. It also enables console apps to use GetAncestor(GetConsoleWindow(), GA_ROOT) to get directly at the HWND of the Terminal (but don't please).

This is tested with our internal partners and seems to work for their scenario.

See #2988, #12799, #12515, #12570.

PR Checklist

  • This is 1/3 of #2988.
  • I work here

TODOS:

  • Clean up dead code, scratch, etc.
  • Especially make sure that the reparenting flow makes sense post-startup. (for tear-out, #5000. Won't be able to test now, but should work then)
  • Come up with a total list of scenarios where the z ordering is messed up
  • Sync with auth folks to see if this worked
  • merge with #12515 work
  • tests?
