PROFILE
Liu Jinchang
Worked on linuxdeepin/dde-file-manager, delivering features that enhanced file system compatibility, menu usability, and user experience across desktop environments. Developed ULNFS file system support using C++ and Linux scripting, enabling seamless mounting and configuration within the file manager. Improved menu structure by implementing unified item grouping and adjacent action organization, leveraging Qt and UI/UX design principles to streamline navigation. Addressed stability by rolling back incomplete migrations and cleaning up legacy configurations. Introduced a configurable input method toggle to prevent unwanted soft keyboard activations on touch devices. Demonstrated a methodical approach to feature delivery, risk mitigation, and maintainable code evolution.

Jul 1, 2026In July 2026, delivered a configurable input method activation toggle for the desktop canvas and organizer views in linuxdeepin/dde-file-manager, reducing unintended soft keyboard pop-ups on touch-screen devices while preserving expected behavior on non-touch devices. Implemented via a new dconfig entry (enableCanvasInputMethod) and gating logic in UI components. Added global dconfig constants (kDesktopDConfName, kKeyCanvasInputMethod) to ensure consistent usage across the UI. The work was completed end-to-end with a single feature commit (e8dd69475db22076aab6cff48ac32ebc423f536a). This aligns with product goals to improve UX on large touch devices and reduce accidental keyboard activations, while maintaining code stability and configurability.

Jan 1, 2026January 2026 (2026-01) Monthly summary for linuxdeepin/dde-file-manager: Implemented action grouping for menu items by a shared identifier to maintain order and keep related actions adjacent, notably in the tag menu scene. Introduced kActionGroupId constant and grouping logic; applied changes to the tag menu to keep color list and tag actions together. Fixed a menu ordering issue, improving UI consistency and user efficiency for tagging workflows. Commit: 191ab93fc0a56c54bd1fa33120d4b8c35629a1ea; Change-Id: Idfec074665e8011d5d7470d8cbe9788c44d4991f

Oct 1, 2024Month 2024-10: linuxdeepin/dde-file-manager. Executed a targeted rollback of the ULNFS long file name feature to preserve stability and compatibility. Reverted the feature addition and the migration from DLNFS to ULNFS, and removed all related configurations, scripts, and installation instructions. This cleanup reduces ongoing maintenance burden and mitigates risk from an incomplete migration. The work focused on risk mitigation, code cleanliness, and clear documentation for future migration planning. Commits involved include the reverts 85082b6924f221684a521316f9a1f1b1f9c6134d and ca2da393899c062e0424ea9e71037e0716413fe9.
