Help With A Custom Implementation of QGraphicsSvgItem

[Abion47]

So I'm trying to follow the code on this thread:

http://www.qtcentre.org/threads/5394...raphicsSvgItem

where the guy apparently discovered that the SVG attributes for things like color can't be changed within the QGraphicsSvgItem itself, so I need to have some kind of wrapper that holds the XML data and can edit it on the fly, then have the QSvgRenderer reload the information. The problem I am getting is that, although the renderer will load information from a file just fine, I can't get it to read from a byte array.

Here's my code snippet:

QDomDocument *doc = new QDomDocument();
QGraphicsSvgItem *item = new QGraphicsSvgItem();
 
QFile *file = new QFile(":/assets/outline.svg");
file->open(QIODevice::ReadOnly);
QTextStream *stream = new QTextStream(file);
QString str = stream->readAll();
doc->setContent(str);
QByteArray barr = doc->toByteArray();
file->close();
 
QSvgRenderer *renderer = new QSvgRenderer();
 
std::cout << renderer->load(QString(":/assets/outline.svg")) << std::endl; 	// Returns true
std::cout << renderer->load(barr) << std::endl; 				// Returns false
 
item->setSharedRenderer(renderer);
 
scene->addItem(item);

QDomDocument *doc = new QDomDocument();
QGraphicsSvgItem *item = new QGraphicsSvgItem();

QFile *file = new QFile(":/assets/outline.svg");
file->open(QIODevice::ReadOnly);
QTextStream *stream = new QTextStream(file);
QString str = stream->readAll();
doc->setContent(str);
QByteArray barr = doc->toByteArray();
file->close();

QSvgRenderer *renderer = new QSvgRenderer();

std::cout << renderer->load(QString(":/assets/outline.svg")) << std::endl; 	// Returns true
std::cout << renderer->load(barr) << std::endl; 				// Returns false

item->setSharedRenderer(renderer);

scene->addItem(item);

To copy to clipboard, switch view to plain text mode 

(My actual code doesn't have both "renderer->load" lines in series like this. I just put them in the snippet to show what I am using.)

As the comments show, when the renderer loads the SVG straight from the file, it loads fine and I see my graphic, but when I try and load the byte array that went through the QDomDocument, I get nothing. Does anyone have any idea as to why this might be the case?
