<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">according to the <a href="http://doc.qt.io/qt-5/qmetatype.html#qRegisterMetaType-1" style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">Qt Docu</a> <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">qRegisterMetaType</code> is (only) needed under some circumstances:</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;"><div class="codehilite" style="background: #f8f8f8"><pre style="line-height: 125%">To use the type T in QVariant, using Q_DECLARE_METATYPE() is sufficient. To use the type T in queued signal and slot connections, qRegisterMetaType<T>() must be called before the first connection is established.
</pre></div>
</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">To prevent complicated issues if we use queued connections ourself in the future the <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">qRegisterMetaType</code> should go somewhere else. I think it should be <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">mymoneymoney.cpp</code> for <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">MyMoneyMoney</code> but I am unsure here.</p></pre>

However, in terms of satisfying the requirement that it "must be called before the first connection is established," making it a static variable initializer should be sufficient regardless of where it is placed. Static initializers are run when the .so is loaded so they'll be executed before any "real" code gets run.</p></pre>

This violates the concept of enclosed units. To be specific; the <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">qRegisterMetaType()</code> call should be in the <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">kmm_mymoney</code> library. To suppress the warnings only they could go in the <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">kmymoneywidgets</code> library (but not <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">kmm_widgets</code>). Your static initializer trick is cool.</p></pre>
