Move window-specific JS/CSS injection from platform-specific execJS calls
to a unified approach using the runtime. The runtime now fetches
/wails/init.js and /wails/init.css from the asset server after signaling
ready, and the backend identifies which window made the request via the
existing x-wails-window-id header.
This fixes the bug where JS/CSS options were not executed when using URL
navigation (only worked with HTML option), and provides a single,
consistent implementation across all platforms.
Changes:
- Add middleware handlers for /wails/init.js and /wails/init.css
- Remove platform-specific JS/CSS injection from Windows, Linux, macOS
- Add init script loading to runtime JS (fire-and-forget)

- Included guidance for Windows implementation
* chore(v3/examples): remove html-dnd-api example
The drag-n-drop example now demonstrates both external file drops
and internal HTML5 drag-and-drop, making this separate example redundant.
* docs(v3): move drag-and-drop implementation details to runtime-internals
- Add drag-and-drop section to contributing/runtime-internals.mdx
- Remove IMPLEMENTATION.md from example (content now in proper docs)

* fix(v3/test): use correct CSS class name file-drop-target-active
* chore(v3/test): remove dnd-test directory
This was a development test file that shouldn't be in the PR.
The drag-n-drop example serves as the proper test case.
* docs(v3): update Windows file drop comment to reflect implemented fix
Remove stale TODO - enableFileDrop flag is now injected in navigationCompleted
* refactor(v3): make handleDragAndDropMessage unexported
Internal method only called by application event loop, not part of public API.
fix(macos): fix print dialog not opening and add Window.Print() to runtime (#4290)
The print dialog was not opening on macOS because the CGO windowPrint function was passing the wrong pointer type to NSPrintOperation's runOperationModalForWindow method. It was passing the raw void* window instead of the properly cast WebviewWindow* nsWindow.
This also adds a Window.Print() method to the JavaScript runtime, allowing frontend code to trigger the print dialog directly without needing a Go binding.
Changes:
- Fix webview_window_darwin.go to use nsWindow instead of window
- Add WindowPrint constant (51) and handler to messageprocessor_window.go
- Add Print() method to window.ts in the runtime
- Rebuild bundled runtime (runtime.js and runtime.debug.js)
- Add print example in v3/examples/print to demonstrate both Go API and JS runtime methods
- Update API documentation for Window.Print() in both Go and JavaScript references

* All changes are complete. Here's a summary of what was implemented for issue #3896:
## Summary
Added four new WebKit2 load-change events for Linux to match WebKitGTK's documented load-change signals:
### New Events
| Event | ID | WebKit Signal | Description |
|-------|-----|---------------|-------------|
| `WindowLoadStarted` | 1059 | `WEBKIT_LOAD_STARTED` | Fired when page load begins |
| `WindowLoadRedirected` | 1060 | `WEBKIT_LOAD_REDIRECTED` | Fired when a redirect occurs |
| `WindowLoadCommitted` | 1061 | `WEBKIT_LOAD_COMMITTED` | Fired when load is committed |
| `WindowLoadFinished` | 1062 | `WEBKIT_LOAD_FINISHED` | Fired when load completes |
### Files Modified
1. **`v3/pkg/events/events.go`** - Added new event types to `linuxEvents` struct and updated all platform event IDs (Mac, Windows, iOS shifted by +4 to accommodate new Linux events)
2. **`v3/pkg/events/events_linux.h`** - Added C defines for new events
3. **`v3/pkg/application/linux_cgo.go`** - Updated `handleLoadChanged()` to dispatch all four load events
4. **`v3/UNRELEASED_CHANGELOG.md`** - Documented the new feature
### Backward Compatibility
- The existing `WindowLoadChanged` event (1058) continues to fire on `WEBKIT_LOAD_FINISHED` for backward compatibility
- `WindowLoadFinished` also fires on `WEBKIT_LOAD_FINISHED` for consistent naming with the new events
Would you like me to commit these changes?
* These are the remaining changes that need to be committed - the generator properly updated:
1. `events.txt` - source of truth for events
2. `event_types.ts` - TypeScript runtime types for JS/TS clients
3. `events_darwin.h` - Mac C header with updated event IDs
4. `events_ios.h` - iOS C header with updated event IDs
These are the final changes needed on top of the previous commit. Would you like me to commit these changes?
* chore: add new Linux WebKit2 load events to known_events.go
Add WindowLoadStarted, WindowLoadRedirected, WindowLoadCommitted,
and WindowLoadFinished to the known events registry.

* Update UNRELEASED_CHANGELOG
* refactor(linux): remove deprecated WindowLoadChanged event
Remove the legacy WindowLoadChanged event and replace all internal
references with WindowLoadFinished. This simplifies the event system
by having granular events (LoadStarted, LoadRedirected, LoadCommitted,
LoadFinished) rather than a generic LoadChanged that fired on any state.
- Remove WindowLoadChanged from events.go and event_types.ts
- Update linux_cgo.go to only fire WindowLoadFinished
- Update webview_window_linux.go hooks to use WindowLoadFinished
- Regenerate runtime bundles and known_events
- Update events documentation

* fix: Move HandlePlatformFileDrop to window._wails internal API
Fixes#4489
## Problem
The npm package @wailsio/runtime doesn't work for drag-and-drop because
Go backend calls window.wails.Window.HandlePlatformFileDrop(), but the
npm package doesn't populate window.wails (by design for encapsulation).
## Root Cause
PR #3295 (March 2024) intentionally removed window.wails assignment from
the npm package to improve encapsulation. However, this broke platform
handlers that Go backend relies on.
## Solution
Move HandlePlatformFileDrop from public API (window.wails) to internal
API (window._wails), following the existing pattern:
- window._wails.invoke
- window._wails.environment
- window._wails.flags
## Changes
- Register handlePlatformFileDrop in window._wails namespace
- Update Go backend to call window._wails.handlePlatformFileDrop()
- Use camelCase naming for consistency with other internal API methods
- Rebuild bundled runtime with changes
## Benefits
✅ npm package works without window.wails pollution
✅ Maintains encapsulation of public API
✅ Platform handlers clearly separated as internal
✅ Follows existing internal API conventions

* Replace fmt.Printf debug statements with globalApplication.debug
Replace all fmt.Printf debug logging statements in drag-and-drop
functionality with proper globalApplication.debug calls. This provides:
- Consistent logging with the rest of the application
- Proper key-value structured logging
- Better integration with the application's logging system
- Cleaner debug output format
Changes:
- application_darwin.go: Replace 2 fmt.Printf calls
- webview_window.go: Replace 6 fmt.Printf calls
- webview_window_windows.go: Replace 13 fmt.Printf calls
- Remove unused fmt import from application_darwin.go
All debug messages maintain the same information but now use
structured logging with key-value pairs instead of printf formatting.

* Add nil checks to WindowEventContext methods
Ensure all WindowEventContext methods properly handle nil c.data
by initializing the map when it's nil. This prevents panics when
methods are called on contexts that haven't been properly initialized.
Changes:
- DroppedFiles(): Add nil check and map initialization
- setCoordinates(): Add nil check and map initialization
- setDropZoneDetails(): Add nil check and map initialization
- DropZoneDetails(): Add nil check and map initialization
All methods now follow the same pattern as setDroppedFiles()
where a nil data map is automatically initialized to prevent
runtime panics during drag-and-drop operations.
