Could you please explain why this needs to be static?</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Also, you could just combine the QSharedPointer and the normal pointer.</p></pre>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Maybe we can disable this class's constructor and just have a <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">static QQmlObjectSharedEngine* instance()</code> method? It'll make the semantics much clearer.</p></pre>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Adds a class called QuickViewSharedEngine that has the same behavior as QmlObjectSharedEngine(using it): static QQmlEngine, separed rootContexts() for each instance.
This is used by desktopviews and panelviews to share their engine.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Unfortunately it may not be possible to get the applet configuration dialogs to use this, since they still need a separed engine in order to have a different controls style (qstyle based) than the stuff in the desktop/panel</p></pre>
