From 6722ed4d5cead460592967bc560ab4d207e4518d Mon Sep 17 00:00:00 2001 From: ubuntu1804 Date: Tue, 11 Nov 2025 13:03:59 +0800 Subject: [PATCH] Split ScreenLockDetector into platform classes Introduce ScreenLockDetectorBase and move platform logic into ScreenLockDetectorLinux and ScreenLockDetectorMacOS. Rename mac files to *_macos, add new base/linux source files, and update CMakeLists to include them. Convert ScreenLockDetector into a factory/facade that creates and forwards signals to the platform detector. Add refactoring docs and a migration guide. --- CMakeLists.txt | 16 +- REFACTORING_SUMMARY.md | 242 +++++++++ docs/CLASS_DIAGRAM.md | 270 ++++++++++ docs/MIGRATION_GUIDE.md | 296 +++++++++++
