Add standalone test apps and Playwright specs for wxWidgets WASM
- Add 10 standalone test apps for isolated component testing: - menu, toolbar, layout, aui, clipboard, filedialog, grid - dialog, timer, tree (3 new) - Add 12 Playwright e2e test specs for automated testing - Update Makefile with GL/non-GL build configurations - Update build script to list all standalone tests - Add WHATWORKS.md documenting KiCad wxWidgets coverage - Update .gitignore for build artifacts Test results: - 79 Playwright tests pass - wxGrid crashes (memory access out of bounds) - wxTreeCtrl crashes (similar issue) - wxDialog/wxMessageBox events fire but no visual popup 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

## BROKEN Features
|
||||
|
||||
### wxGrid - CRASHES
|
||||
- **Status**: Standalone grid_test crashes with "memory access out of bounds"
|
||||
- **KiCad Impact**: HIGH - KiCad uses wxGrid for property editors, DRC results, BOM
|
||||
- **Evidence**: wxgrid-dedicated-page.png shows red error "Exception thrown"
|
||||
- **Error**: `RuntimeError: memory access out of bounds` at wasm-function[101]
|
||||
|
||||
### wxTreeCtrl - CRASHES
|
||||
- **Status**: Standalone tree_test crashes on startup
|
||||
- **KiCad Impact**: HIGH - KiCad uses wxTreeCtrl for hierarchy browsers, component trees
|
||||
- **Evidence**: tree-01-loaded.png shows red error "Exception thrown, see JavaScript console"
|
||||
- **Note**: Similar crash pattern to wxGrid - both may have same underlying issue
|
||||
|
||||
### wxMessageBox/wxDialog - NO VISUAL POPUP
|
||||
- **Status**: Events fire but no dialog appears
|
||||
- **KiCad Impact**: MEDIUM - Alert messages, confirmations
|
||||
- **Evidence**: dialogs-msgbox-info-open.png shows buttons but no popup
|
||||
- **Behavior**: "Showing Info message box" logged, then immediately "closed"
|
||||
|
||||
### wxClipboard - LIMITED
|
||||
- **Status**: App loads but "Could not open clipboard" errors
|
||||
- **KiCad Impact**: MEDIUM - Copy/paste operations
|
||||
- **Evidence**: Clipboard logs show open errors
|
||||
- **Cause**: Browser clipboard API restrictions

|
||||
## KiCad Readiness Assessment
|
||||
|
||||
### Ready for KiCad
|
||||
1. Window management (wxFrame, wxMenuBar, wxToolBar, wxStatusBar)
|
||||
2. Panel docking (wxAuiManager)
|
||||
3. Layout controls (wxSplitterWindow, wxScrolledWindow, wxNotebook)
|
||||
4. Basic controls (buttons, checkboxes, radio buttons, sliders)
|
||||
5. Text input (single/multi-line)
|
||||
6. List controls (wxListBox, wxChoice, wxComboBox)
|
||||
7. OpenGL rendering (immediate mode, vertex arrays, matrix ops)
|
||||
8. Drawing/painting (wxDC, mouse events)
|
||||
|
||||
### Needs Work for KiCad
|
||||
1. **wxGrid** - Critical for property editors, DRC, BOM tables
|
||||
2. **wxMessageBox/wxDialog** - Alerts and confirmations
|
||||
3. **wxClipboard** - Copy/paste (browser limitations)
|
||||
|
||||
### Untested for KiCad
|
||||
1. wxTreeCtrl (hierarchy browser)
|
||||
2. wxDataViewCtrl (advanced lists)
|
||||
3. wxRichTextCtrl (formatted text)
|
||||
4. wxStyledTextCtrl (code editor)
|
||||
5. Printing support
|
||||
6. Drag and drop
|
||||

||||
|
||||
## Build Notes
|
||||
|
||||
### GL vs Non-GL Apps
|
||||
- Main app (minimal_test) uses `LDFLAGS_GL` with OpenGL support
|
||||
- Standalone test apps use `LDFLAGS_NOGL` without OpenGL
|
||||
- This prevents "_glBegin is not defined" crashes in non-GL apps
|
||||
|
||||
### Build Command
|
||||
Always use the build script:
|
||||
```bash
|
||||
cd tests/wasm-app && ./build-test-apps.sh
|
||||
```
