Summary

Fixed changes from PR #908 to pass automated CI workflows and tests, ensuring compatibility with updated dependencies, environment configurations, and the latest (11/17/2024) main branch.

Details and comments

0. Built on top of changes made by @obrienpja in PR #908.

1. Changes to QWidget_PlaceholderText and QTableView_AllComponents:

   • Refactored the QWidget_PlaceholderText class to ensure proper initialization and compatibility with PySide6.
   • Resolved issues with placeholder text styling by updating palette usage to align with PySide6 standards.
   • Updated QTableView_AllComponents to correctly inherit and integrate with QWidget_PlaceholderText, ensuring both functionality and visual styling work seamlessly.
   • Fixed initialization errors and ensured that the placeholder label behaves as intended when no components are available.

2. Requirements and environment updates:

   • Updated the environment.yml file to use stable, OS-agnostic dependencies for Python 3.10.
   • Added missing dependencies, such as pyaedt, to ensure a consistent build across different operating systems.
   • Ensured that all dependencies align with the workflows and requirements in the lab's testing environment.

3. Testing and validation:

   • Verified that the changes integrate seamlessly with the existing workflows and CI processes used in our lab.
   • Tested the updated branch against the current main branch workflows to confirm identical behavior.
   • All CI tests now pass successfully across all supported platforms (Windows, macOS, Ubuntu) and Python versions (3.9 and 3.10).

Thank you, @shanto268! The tests are running. This is a giant PR, so it would be good to have more eyes on it than just you and me. Has anyone else from your lab tried this? I think after merging this, we could bump the Qiskit Metal version from 0.1.5 to 0.2. I just want to make sure it runs.

[shanto268]

Thanks! All tests have passed now, thankfully.

I totally agree—it indeed is a big PR, so having more eyes on it is a great idea. I’ll be using this version myself and asking my lab mates to do the same over the next couple of weeks. If everything runs smoothly, I’ll report back.

I’d also like to invite the great people—@PP501 and @DavidSomm—of the SQDMetal team to see if they can help beta test this version as well.

Awesome, that would be superb! Thank you everyone. Please don't be shy to post any comments here.
