Bundled Embedded UI Extension Example
Demonstrates binding Qt windows to bundled EmbeddedUIExtensionAbility instances by key.
The example creates two identical windows, each containing a label and a button that rewrites the label text. Each window is bound to a QBundledEmbeddedUiExtensionAbility instance with QtOhosExtras::setBundledAbilityAndQWindowBindingKeyForQWindow(), using the binding keys "A" and "B". The underlying QWindow is created up front by calling QWidget::winId() before the binding function is invoked.
Note: The bound windows must have no parent or transient parent and must not be shown by the application. A window becomes visible only when the extension ability instance whose want carries the matching io.qt.public.bundledAbilityAndQWindowBindingKey parameter is started.
