QmlBridge

Create a view

Link FluentQt::QmlBridge, activate a QmlSession, and create QmlView widgets. Models you expose to QML stay owned by your application. Deactivating the session unloads the QML scenes and keeps your views and models.

#include <FluentQt/QmlBridge.h>

// The session uses its own PluginManager; window and models stay caller-owned.
auto* session = new fluent::qmlbridge::QmlSession(window, window);
if (session->activate()) {
    auto* qmlView = session->createView(parentWidget);
    // Load a QML scene into qmlView.
}

from fluentqt.qmlbridge import QmlSession

# The session uses its own PluginManager; window and models stay caller-owned.
session = QmlSession(window, window)
if session.activate():
    qml_view = session.createView(parent_widget)

Graphics API and theme

If Quick shares a window with SpatialView or QOpenGLWidget, call QmlSession::prepareApplication() before the first Quick surface is created; activating a session does not choose a graphics API. QmlTheme gives QML the host's theme tokens as the read-only fluentTheme object.
