Use this skill when
Developing desktop applications using Python (PyQt6 or PySide6).
Designing native-looking UIs with custom styling (QSS) or Material Design.
Implementing complex GUI patterns like Model/View (QAbstractItemModel).
Handling long-running tasks without blocking the UI using QThread/QRunnable.
Packaging and distributing Python desktop apps (PyInstaller, fbs, Nuitka).
Instructions
Prefer PyQt6 or PySide6 over older versions unless specified.
Use Model/View architecture for large datasets or complex lists.
Always separate UI logic from business logic.
Use QSS (Qt Style Sheets) for modern, premium aesthetics.
Implement responsive layouts using QLayout (QHBoxLayout, QVBoxLayout, QGridLayout).
Capabilities
UI Design & Aesthetics
Native Look & Feel: Adapting to Windows, macOS, and Linux conventions.
Custom Styling: Advanced QSS implementation, glassmorphism, and dark mode support.
Modern Themes: Integration with qt-material or custom SVG-based icons.
Animations: Using QPropertyAnimation and QParallelAnimationGroup for smooth transitions.
Core Architecture
Signals & Slots: Thread-safe communication between components.
Model/View Framework: Custom models for QTableView, QTreeView, and QListView.
Multithreading: Proper use of QThread, QThreadPool, and signals to keep UI responsive.
Event Loop Mastery: Custom event filters and overriding event() for low-level control.
System Integration
System Tray: Implementing background apps with QSystemTrayIcon.
Native Dialogs: Using QFileDialog, QColorDialog, and QMessageBox for system consistency.
Settings Persistence: Managing app state with QSettings (INI, Registry, Plist).
Clipboard & Drag-and-Drop: Managing deep system interactions.
Deployment & Hardening
Packaging: Freezing apps with PyInstaller, briefcase, or Nuitka.
Resource Management: Compiling icons and images into .qrc / _rc.py files.
Hardening: Integrating with pyarmor for code protection.
Example Interactions
"Create a PyQt6 dashboard with a side panel and glassmorphic tables."
"Implement a background file processor in PyQt using QThread and a progress bar."
"Style my PyQt application with a modern dark theme and custom SVG icons."
"Set up a Model/View architecture for a searchable contact list."
