Relates to the chatbot module PyQt6 migration task under the FOSSEE eSim AI Chatbot internship.
Purpose
The chatbot module (
src/chatbot/+src/frontEnd/Chatbot.py) had already been migrated to PyQt6 but the rest of the frontEnd —Application.py,DockArea.py,Workspace.py— was still on PyQt5, causingAttributeErrorcrashes at runtime since PyQt6 requires fully scoped enums (e.g.Qt.AlignCenter→Qt.AlignmentFlag.AlignCenter), so the entire frontEnd has now been migrated to PyQt6 to match the chatbot module.Approach
Migrated all PyQt5-style unscoped enums to PyQt6 scoped equivalents across
Application.py,DockArea.py,Workspace.py, andChatbot.pycoveringAlignmentFlag,Orientation,WindowType,ScrollBarPolicy,TextElideMode,TextFlag,TextFormat,CursorShape,ItemDataRole,CheckState,QFrame.Shape/Shadow,QTextCursor.MoveOperation/MoveMode,QSizePolicy.Policy,QDialog.DialogCode, andQMessageBox.StandardButton/Icon. Addedsrc/run_chatbot.pyas a standalone launcher that insertssrc/into the Python path, initializes aQApplication, importsChatbotGUIdirectly fromfrontEnd.Chatbot, and launches the window — bypassingApplication.pyentirely so the chatbot can be tested in isolation without depending on parts of the codebase still on PyQt5.
