magdev 91f4d619fc v0.2.0 (6/N): docs/native-dialogs.md — boundary doc + Qt.labs.platform examples
PLAN.md §12 noted "Native dialogs (file pickers, notifications) — where
do they live?" as an open question with the bias "QML side via Qt".
That bias was never written up; without the doc, a Symfony developer
new to Qt would reasonably reach for "POST /api/show-dialog" or roll
a custom QML "FileDialog" using Window + ListView. Both are wrong.

The doc:
- States the boundary plainly (native UI = QML side, never PHP) plus
  the architectural reason (PHP's process can't reach the user's
  window manager; Qt's can and already wraps every platform's
  native API).
- Walks through Qt.labs.platform.FileDialog / MessageDialog /
  SystemTrayIcon / StandardPaths with copy-pasteable examples so
  apps don't need to discover Qt.labs the hard way.
- Explains the trigger-vs-effect split: user-initiated confirmations
  open from the QML handler that fired the action; server-side
  events route through Mercure and let QML decide how to surface
  them (toast / dialog / tray notification).

Anti-pattern callouts: don't dispatch dialogs from Doctrine listeners,
don't add HTTP endpoints whose only job is to trigger UI side-effects,
don't roll a custom QML file browser.

Notifications caveat: Qt.labs.platform.SystemTrayIcon::showMessage
covers the common case but routes through the tray. Richer
notifications (action buttons, replies) need platform-specific code
and are deferred — flagged in-doc.

PLAN.md §13 also mentioned "ship a small Q_INVOKABLE helper for the
common cases". Skipped: every common case Qt.labs.platform already
covers, and a wrapper would just shadow upstream's API. If a future
need surfaces a real gap (XDG portal notifications without tray,
say), that's the time to add framework-side code; the doc will
point at it.

No code changes; doc-only.

php-qml

A framework for native desktop applications with a Symfony / FrankenPHP backend and a Qt / QML frontend, packaged as a single distributable per OS.

Status: Phase 5 / pre-v0.1.0. Phases 04a are merged (working framework, real POC, Linux AppImage, auto-update, release CI). macOS and Windows packaging are deferred to 4b/4c. See CHANGELOG.md.


What it is

php-qml lets a PHP developer write a desktop app using ordinary Symfony on the backend and ordinary QML on the frontend. The two halves run as a process pair inside one bundled binary:

  • A Qt/QML host owns the window, input, and rendering.
  • A bundled FrankenPHP child runs a Symfony app in worker mode.
  • They communicate over a local socket — HTTP for commands and queries, Mercure SSE for state push.

It is not a PHP↔Qt language binding — the languages run in separate processes; the bridge is a wire protocol, not an FFI layer. That deliberately avoids the failure mode that left php-gtk and php-qt unmaintained.

60-second tour

git clone https://src.bundespruefstelle.ch/magdev/php-qml && cd php-qml

# Scaffold a fresh app
./bin/php-qml-init my-app

# Run it
cd my-app
make doctor                 # readiness check
make dev                    # FrankenPHP --watch + Qt host

Add a reactive resource (entity + REST controller + QML snippet) with one maker:

cd my-app/symfony
bin/console make:bridge:resource Todo
bin/console make:migration && bin/console doctrine:migrations:migrate -n

make dev opens the Qt window, connection state flips to Online, and the generated TodoList.qml shows a list whose ReactiveListModel is auto-subscribed to app://model/todo over Mercure. There is no handwritten cross-side glue.

For a non-trivial app with a multi-window test, crash-recovery test, and AppImage packaging, see examples/todo/.

Design rationale and roadmap live in PLAN.md. User-facing changes per release are in CHANGELOG.md.

Tech stack

PHP 8.4+ · Symfony 8 · Doctrine ORM 3 · FrankenPHP 1.12+ (worker mode) · Mercure · Qt 6.5+ · CMake · Composer · Gitea Actions

Roadmap

  • Phase 0 throwaway transport spike.
  • Phase 1 framework skeleton, dev mode, single-instance lock, CI quality gate.
  • Phase 2 reactive models, update semantics, headline maker.
  • Phase 3 POC todo app, integration + snapshot tests.
  • Phase 4a bundled mode, Linux AppImage, release CI, AppImageUpdate.
  • Phase 4b/4c macOS / Windows packaging.
  • Phase 5 🚧 DX polish — dev console, init script, hot-reload docs, v0.1.0 prep.

Contributing

Active development happens on the dev branch; main only carries release commits. Pull requests target dev.

cd framework/php && composer quality   # PHPStan + cs-fixer + PHPUnit
cd examples/todo  && make quality      # adds qmllint + integration test

A dedicated CONTRIBUTING.md arrives with Phase 5's wrap-up.

Versioning

Semantic VersioningMAJOR.MINOR.BUGFIX. Pre-v1.0.0, minor bumps may break public API.

License

To be decided before v0.1.0 is tagged. The framework's own code will be permissively licensed; Qt is shipped under LGPL with relinkability obligations — see PLAN.md §12.
