Replace the usage of PyQt5 in the project with PyQt6.
Why we need the feature
Up-to-Date Framework: PyQt6 is the latest version of the PyQt framework, providing support for the newest features and updates from the Qt library. Migrating to PyQt6 ensures that the project remains current and can leverage improvements and optimizations made in the latest version.
Long-Term Support and Maintenance: As PyQt6 is actively maintained, using it will facilitate better long-term support. Relying on an older version like PyQt5 may lead to compatibility issues as dependencies and operating systems evolve.
Enhanced Features: PyQt6 introduces new modules and functionalities that are not available in PyQt5, allowing for potential enhancements in the application's user interface and performance.
How to implement and why
Step 1: Update Dependencies
Modify requirements.txt and requirements.pytorch.txt to replace PyQt5 with PyQt6.
Reason: Ensures that when the environment is set up, PyQt6 is installed instead of PyQt5.
Step 2: Update Import Statements
Go through the codebase, particularly in the game_manager directory, and update all import statements from PyQt5 to PyQt6.
Example: Change from PyQt5 import QtWidgets to from PyQt6 import QtWidgets.
Reason: PyQt6 modules are organized similarly to PyQt5 but require explicit imports from the PyQt6 namespace.
Step 3: Address API Changes
Enum and Flag Access: PyQt6 enforces scoped enumeration access.
Update code accessing enums, e.g., change Qt.AlignCenter to Qt.AlignmentFlag.AlignCenter.
Reason: PyQt6 requires full enumeration paths to improve code clarity and maintainability.
Print Function and Unicode Handling: Ensure that all print statements are compatible with Python 3 standards, as PyQt6 only supports Python 3.6+.
Reason: Maintains compatibility and prevents runtime errors.
Module Renaming: Some modules and classes have been renamed or relocated.
Verify and update any such instances based on the PyQt6 documentation.
Reason: Prevents import errors and ensures the application runs smoothly.
Step 4: Testing
Run the application to identify any runtime issues.
Perform regression testing to ensure that all functionalities work as expected after the migration.
Reason: Confirms that the migration has not introduced any bugs and that the application remains stable.
About backward compatibility
Python Version Requirement: PyQt6 requires Python 3.6 or higher.
Impact: Environments running older Python versions will not be compatible.
Mitigation: Update the project's documentation to specify the new Python version requirement.
Dropping Support for PyQt5: Migrating to PyQt6 means the code will no longer be compatible with PyQt5 without additional abstractions.
Reasoning: Maintaining compatibility with both versions would add unnecessary complexity and hinder leveraging new features exclusive to PyQt6.
Decision: Given the benefits of using PyQt6 and the importance of keeping the project up-to-date, it is acceptable to discontinue backward compatibility with PyQt5.
Developers and users should upgrade their environments accordingly.
Action: Update the README and documentation to inform stakeholders of the changes and provide guidance on updating their setups.
