What is the mime-type for All Files
<p>Simple Question: What is the mimetype for "All Files", i.e. <code>*</code> or <code>*.*</code></p>

<p>I need it to add the option "All Files" to a filter for files in the <code>QFileDialog</code>:</p>

<pre><code>QFileDialog dialog(this);
QStringList mTypes= byteToStringList(QImageReader::supportedMimeTypes());
mTypes.append("???");//what to add here to get "All Files (*)" or "All Files (*.*)"
dialog.setMimeTypeFilters(mTypes);
</code></pre>
