[Kopete-devel] Re: Recent KHTML/Qt changes cause crash in Kopete

Sun Mar 2 23:41:49 GMT 2003

Initial document structure is always:
<html><body bgproperties=\"fixed\"></body></html>

After this, nodes are created and appended as follows:
DOM::HTMLElement newNode = chatView->document().createElement( QString::fromLatin1("div") );
newNode.setInnerHTML( resultHTML );
chatView->htmlDocument().body().appendChild( newNode );

Typical contents of resultHTML would be:

<table width=\"100%\" cellspacing=\"0\" cellpadding=\"0\" border=\"0\">
	<tr>
		<td><font color=\"#E11919\"> (3:45 PM) </font><font color=\"red\"><b>Jason Keirstead:</b></font>Message Text</td>
	</tr>
</table>

Note, the \" is from C escaping, that isn't part of the HTML :P
