RPL Predefined Function Help in RiverWare [21] -- allow image overflow
Bug Number: n/a
Release notes (y/n): no (not yet)
For Release Nums: 6.7

(1) Devised HTML CSS -- generated by the python script -- to prevent the 
 image from imposing a minimum width on the containing element (typically, 
 a table cell).  See this example (image and HTML. For the latter, 
 try making your browser window narrow):

This accomplished by placing the image element in a DIV element with 
limited width and assigning the "show" to the image's overflow style, 
like this:

   <div style="width:10px;">
     <img src="..." style="overflow:show;" ...>
   </div>

See the following python script code in function appendCloneChildren 
 (targNode, srcNode):

   ... ... ...
   elif isImg:
     # In order to prevent the image from imposing a minimum width on the
     # content (typically inside a table cell, as are math formula images)
     # place the image inside a DIV element with limited width, but allow
     # the image to overflow its container. (The latter is done explicitly
     # even though "overflow:show" seems to be the default).
     #
     condNode.setAttribute ("style", "overflow:show;")
     imgWrapDiv = newDoc.createElement ("div")
     imgWrapDiv.setAttribute ("style", "width:10px;")
     imgWrapDiv.appendChild (condNode)
     targNode.appendChild (imgWrapDiv)     


(2) Solved the problem of the following error being reported to the console 
 when calling QWebView::setHtml (const QString& html, const QUrl& baseUrl):

   "QNetworkAccessFileBackendFactory: URL has no schema set, 
    use file:// for files"

This was fixed by calling QUrl::setScheme(), as follows:

   _rplFuncDocBaseUrl = QUrl (embedHelpPath);
   _rplFuncDocBaseUrl.setScheme ("file");
