Probably a function like setMimeExcludeFilter. The function would eventually
call the same one from the used KDirLister.
But this is surely not possible by KDE 4.5

<br>
I am currently writing an application that is using KFileDialog (as<br>
QFileDialog does not support mimetype filters on files) as follows:<br>
<br>
                        KFileDialog open(m_edit-&gt;fileName(), QString(), this);<br>
                        open.setCaption(i18nc(&quot;@title:window&quot;, &quot;Open \
Document&quot;));<br>  open.setOperationMode(KFileDialog::Opening);<br>
                        open.setMimeFilter(QStringList() &lt;&lt; \
&quot;text/plain&quot; &lt;&lt; &quot;text/html&quot;,<br> \
                m_edit-&gt;mimeType());<br>
                        open.setMode(KFile::File | KFile::ExistingOnly | \
KFile::LocalOnly);<br> <br>
                        if (open.exec())<br>
                                    loadFile(open.selectedFile());<br>
<br>
The loadFile function then does:<br>
<br>
            KMimeType::Ptr type = KMimeType::findByPath(fileName);<br>
            if (!m_edit-&gt;loadDocument(fileName, type-&gt;name()))<br>
                        ...<br>
<br>
to get the mimetype of the file being loaded (as<br>
open.currentMimeFilter() could return &quot;text/plain&quot; for HTML files and<br>
thus show the HTML code instead of the results from setHtml).<br>
<br>
This is working, except that if the user selects plain text, they can<br>
select a format like RTF or XML. If they do this, findByPath returns a<br>
mimetype different to text/plain (e.g. application/rtf for RTF files).<br>
This makes my m_edit-&gt;loadDocument function fail (unsupported<br>
mimetype).<br>
<br>
Also, the user sees HTML files displayed in the dialog when text/plain.<br>
