# WebDrop Bridge
|
|
|
|
> Professional Qt-based desktop application for intelligent drag-and-drop file handling between web applications and desktop clients (InDesign, Word, Notepad++, etc.)
|
|
|
|
  
|
|
|
|
## Overview
|
|
|
|
WebDrop Bridge is a sophisticated desktop bridge application that intercepts text-based drag-and-drop operations from embedded web applications and converts them into native file-drag operations recognized by professional desktop applications.
|
|
|
|
### The Problem
|
|
Modern web applications can transmit file paths via drag-and-drop, but desktop applications expect native file handles. Traditional solutions fail because:
|
|
- Browsers sandbox cross-origin drag-and-drop
|
|
- Web apps can't access the file system directly
|
|
- Native apps need OS-level file handles (CF_HDROP on Windows, NSFilenamesPboardType on macOS)
|
|
|
|
### The Solution
|
|
WebDrop Bridge embeds a web application in a Qt container with full filesystem access, intelligently intercepting and converting drag operations at the OS boundary.
|
|
|
|
## Features
|
|
|
|
- ✅ **Qt-based Architecture** - Professional Windows support via PySide6 (macOS support planned)
|
|
- ✅ **Embedded Web App** - QtWebEngine provides Chromium without browser limitations
|
|
- ✅ **Drag Interception** - Converts text paths to native file operations
|
|
- ✅ **Path Whitelist** - Security-conscious file system access control
|
|
- ✅ **Configuration Management** - Profile-based settings with validation
|
|
- ✅ **Settings Dialog** - Professional UI for path, URL, logging, and window configuration
|
|
- ✅ **Auto-Update System** - Automatic release detection via Forgejo API
|
|
- ✅ **Professional Build Pipeline** - MSI for Windows, DMG for macOS
|
|
- ✅ **Comprehensive Testing** - Unit, integration, and end-to-end tests (80%+ coverage)
|
|
- ✅ **Continuous Testing** - GitHub Actions test automation
|
|
- ✅ **Structured Logging** - File-based logging with configurable levels
|
|
|
|

|
## Configuration
|
|
|
|
WebDrop Bridge supports two configuration methods:
|
|
|
|
### 1. Settings Dialog (Recommended)
|
|
Launch the application and access the Settings menu to configure:
|
|
- **Paths Tab** - Add/remove allowed root directories
|
|
- **URLs Tab** - Configure allowed web URLs (whitelist mode)
|
|
- **Logging Tab** - Set log level and file location
|
|
- **Window Tab** - Configure window dimensions
|
|
- **Profiles Tab** - Save/load/export-import configuration profiles
|
|
|
|
Profiles are saved in `~/.webdrop-bridge/profiles/`
|
|
|
|
### 2. Environment Variables
|
|
Create a `.env` file in the project root. Available settings:
|
|
|
|
```bash
|
|
# Application
|
|
APP_NAME=WebDrop Bridge
|
|
APP_VERSION=1.0.0
|
|
|
|
# Paths (comma-separated)
|
|
ALLOWED_ROOTS=Z:/,C:/Users/Public
|
|
|
|
# Web URLs (empty = no restriction, items = kiosk mode)
|
|
ALLOWED_URLS=
|
|
|
|
# Interface
|
|
WEBAPP_URL=file:///./webapp/index.html
|
|
WINDOW_WIDTH=1024
|
|
WINDOW_HEIGHT=768
|
|
|
|
# Logging
|
|
LOG_LEVEL=INFO
|
|
ENABLE_LOGGING=true
|
|
```
|
|
|
|
## Testing
|
|
|
|
WebDrop Bridge includes comprehensive test coverage with unit, integration, and end-to-end tests.
|
|
|
|
```bash
|
|
# Run all tests
|
|
pytest tests -v
|
|
|
|
# Run with coverage report
|
|
pytest tests --cov=src/webdrop_bridge --cov-report=html
|
|
|
|
# Run specific test categories
|
|
pytest tests/unit -v # Unit tests only
|
|
pytest tests/integration -v # Integration tests only
|
|
|
|
# Run specific test
|
|
pytest tests/unit/test_validator.py -v
|
|
|
|
# Run tests matching a pattern
|
|
pytest tests -k "config" -v
|
|
```
|
|
|
|
**Test Coverage**:
|
|
- Current target: 80%+
|
|
- Coverage report: `htmlcov/index.html`
|
|
|
|
Integration tests cover:
|
|
- Drag-and-drop workflow
|
|
- Update flow and release detection
|
|
- End-to-end application scenarios
|
|
|
|
## Auto-Update System
|
|
|
|
WebDrop Bridge includes an intelligent auto-update system that:
|
|
|
|
- **Automatic Detection**: Periodically checks Forgejo/GitHub releases API
|
|
- **Smart Caching**: Avoids redundant network calls with smart caching
|
|
- **User Notification**: Alerts users of available updates via UI
|
|
- **Release Notes**: Displays release notes and changes
|
|
- **Safe Deployment**: Only triggers on newer versions
|
|
|
|
The update system is fully integrated with the application and runs in the background without blocking the UI.
|
|
|
|
For technical details, see [docs/ARCHITECTURE.md](docs/ARCHITECTURE.md#update-system).
|
|
|
|
## Building Installers
|
|
|
|
### Windows MSI Installer
|
|
|
|
```bash
|
|
# Build with MSI installer (recommended)
|
|
python build/scripts/build_windows.py --msi
|
|
|
|
# Build with code signing (requires certificate)
|
|
python build/scripts/build_windows.py --msi --code-sign
|
|
```
|
|
|
|
Output:
|
|
- Portable executable: `build/dist/windows/WebDropBridge/WebDropBridge.exe` (~195 MB)
|
|
- Professional MSI installer: `build/dist/windows/WebDropBridge-{version}-Setup.msi`
|
|
- SHA256 checksum: `build/dist/windows/WebDropBridge/WebDropBridge.exe.sha256`
|
|
|
|
**Note on macOS**: Build scripts exist for macOS (DMG generation), but have never been built or tested. macOS support is theoretical at this point. The Qt/PySide6 architecture should support macOS, but platform-specific testing and validation would be required.
|
|
|
|
### Creating Releases
|
|
|
|
For Forgejo/GitHub releases:
|
|
|
|
```bash
|
|
# Windows - Create release with MSI installer
|
|
powershell -ExecutionPolicy Bypass -File build/scripts/create_release.ps1
|
|
```
|
|
|
|
## Development Workflow
|
|
|
|
1. **Create feature branch**
|
|
```bash
|
|
git checkout -b feature/my-feature
|
|
```
|
|
|
|
2. **Write tests first**
|
|
```bash
|
|
pytest tests/unit/test_my_feature.py
|
|
```
|
|
|
|
3. **Implement feature**
|
|
```bash
|
|
# Edit src/webdrop_bridge/...
|
|
```
|
|
|
|
4. **Run quality checks**
|
|
```bash
|
|
tox -e lint,type # Run linting and type checking
|
|
```
|
|
|
|
5. **Submit pull request**
|
|
|
|
## Troubleshooting
|
|
|
|
### Application won't start
|
|
- Ensure Python 3.10+ is installed
|
|
- Check `logs/webdrop_bridge.log` for errors
|
|
- Verify all dependencies: `pip list`
|
|
|
|
### Drag-and-drop not working
|
|
- Verify paths in `.env` are valid
|
|
- Check `ALLOWED_ROOTS` whitelist includes your test directory
|
|
- On macOS, check System Preferences → Security & Privacy → Accessibility
|
|
|
|
### Build errors
|
|
- Clean build directory: `rm -rf build/temp build/dist`
|
|
- Reinstall dependencies: `pip install --force-reinstall -r requirements.txt`
|
|
- Check platform-specific requirements (Windows SDK, Xcode for macOS)
|
|
|
|
## Platform Support
|
|
|
|
| Platform | Version | Status | Notes |
|
|
|----------|---------|--------|-------|
|
|
| Windows | 10, 11 | ✅ Full | Tested on x64, MSI installer support |
|
|
| macOS | 12+ | ⚠️ **Untested** | Possible via Qt/PySide6, but never built or tested. Theoretical support only. |
|
|
|
|
**Note**: WebDrop Bridge is currently developed and tested exclusively on Windows. While the Qt/PySide6 framework supports macOS, we cannot guarantee functionality without actual macOS testing and validation. Contributions for macOS support validation are welcome.
