[Qt-interest] QWebView::setContent (xxx, "application/pdf") crashes adobe reader 8.* [SOLVED]

Hi all,

interesting: googeling for any combination of 'qt webkit adobe reader crash' 
does not produce any usable result ... seems like noone else 
uses 'setContent' like me???

However in case someone else stumbles over this issue, I found a workaround:

1. write the data to a tmp file
2. create an html construct and embed the reader:

	    QString html = QString ("<html>\n"
		  "<head>\n"
		  "   <script type=\"text/javascript\">\n"
		  "   <!--\n"
		  "   function setWidth (width) {\n"
		  "      document.getElementById (\"PdfReader\").style.width=width;\n"
		  "   }\n"
		  "   function setHeight (height) {\n"
		  "      document.getElementById (\"PdfReader\").style.height=height;\n"
		  "   }\n"
		  "   //-->\n"
		  "   </script>\n"
		  "</head>"
		  "<body>\n"
		  "   <object id=\"PdfReader\" name=\"PdfReader\" width=\"%1\" 
height=\"%2\"><embed src=\"file:///%3\" type=\"application/x-pdf\"/>\n"
		  "</object>\n"
		  "</body>\n"
		  "</html>")
	       .arg (width () - 20)
	       .arg (height () - 20)
	       .arg (m_tmpFileName);

3. forward resizing of the view via javascript

void MyWebView::resizeEvent (QResizeEvent * e) {
   QWebView::resizeEvent (e);
   page ()->currentFrame ()->evaluateJavaScript (QString ("setWidth(%1);").arg 
(width () - 20));
   page ()->currentFrame ()->evaluateJavaScript (QString 
("setHeight(%1);").arg (height () - 20));
}

Hope this helps
