HTML inserted into QTextEdit does not conform to style sheet
Question
I have a docked QTextEdit which I am using to emulate a debug terminal in a QT c++ gui, and have it set to a black background with white text.
I am trying to use it to print out error messages from QXmlSchemaValidator , but the messages from the schema validator are in html format, and whenever I insert them into the QTextEdit , it reverts to it's default font, and I end up with black text on a black background.
The actual message is something like:
<html xmlns='http://www.w3.org/1999/xhtml/'>
<body>
<p>Content of element
<span class='XQuery-keyword'>minValue</span> does not match its type definition: <span class='XQuery-data'>fu</span> is not valid according to <span class='XQuery-type'>xs:decimal</span>..
</p>
</body>
</html>
using setAcceptRichText(false) doesn't solve the problem, and if I use insertPlainText() to add text to the lineEdit , it removes all the line breaks and leaves the html tags in the error message, which is unacceptable.
Is there some way I can display the HTML rich text, but without blowing away my style sheet font?

I tested it on my computer. It works perfectly. Use this:
edit->setHtml(htmlDescription);
edit->selectAll();
edit->setTextColor(Qt::green);
//Ok, but clear selection
QTextCursor cur = edit->textCursor();
cur.clearSelection();
edit->setTextCursor(cur);

It's sort of a kludge, but the workaround that I went with was to remove the HTML tags from the schema validator message before adding it to the text edit.
QString errorMsg = msg.statusMessage().remove(QRegExp("<[^>]*>"));
textEdit->setText(errorMsg);
