If I use this, I guess the caller unwraps it into a raw pointer and the issue is still triggered.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Good point about <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">if (!inited)</code>, forgot to change this while renaming. I'll fix it for the next version. Do you know the root cause of the original issue that required the use of this? It is not documented by Qt.</p></pre>
