feat: drag-and-drop files & images into WhatsApp Web (v0.4.0)#6
Merged
Conversation
Account windows are built with Tauri's default OS-level drag-and-drop handler enabled, so wry swallows native file drops (forwarding them as tauri://drag-drop events) before WhatsApp Web's HTML5 drop zone can see them — dropping a file or image did nothing. We don't use Tauri-side drag-drop events, so disable that handler and let the webview hand drops straight to web.whatsapp.com. On WebView2 (Windows) this is what makes HTML5 drag-and-drop work at all. Also guard against a webkit2gtk bug (tauri#9725, #12052) where a dropped file can make the webview navigate to its file:// URL and tear down the live session: cancel any file:// navigation via on_navigation. WhatsApp Web never legitimately loads file:// URLs. Release v0.4.0. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

What
Adds drag-and-drop of files and images into the WhatsApp Web window. Drop a photo, video, or document straight onto a chat to attach it — previously dropping a file did nothing.
Why it didn't work
Account windows are built with Tauri v2's default OS-level drag-and-drop handler enabled. wry then swallows the native file drop (forwarding it as a
tauri://drag-dropevent) before WhatsApp Web's HTML5 drop zone can receive it. On WebView2 (Windows) wry additionally callsSetAllowExternalDrop(false)+ registers a customIDropTarget, fully blocking HTML5 DnD in the page.Fix (
src-tauri/src/window.rs).disable_drag_drop_handler()on the accountWebviewWindowBuilder— we don't use Tauri-side drag-drop events, so this hands drops straight toweb.whatsapp.com. This is the documented requirement for HTML5 DnD on Windows, and also restores it on Linux (webkit2gtk) and macOS (WKWebView)..on_navigation(|url| url.scheme() != "file")— guards against a known webkit2gtk bug (tauri#9725, #12052) where a dropped file can make the webview navigate to itsfile://URL and tear down the live session. WhatsApp Web never legitimately loadsfile://URLs.Verification
