managing QT resource at run-time
Message 1 in thread
How to insert some file into current qt-resource at run time?
I have xml file which holds it's pictures inside binary tag, like this:
<binary content-type="image/jpeg" id="cover.jpg">/9j/4AAQ......SkZJ</binary>
in xml itself, this picture is shown by tag <image l:href="#cover.jpg"/>.
I want to put reconstracted jpeg into QT-resource tree and show this xml in
QTextBrowser with modifictation of image tag to <image
l:href=":/document/cover.jpg"/>.
So the question is how to put some chunk of binary data into qt-resource
tree as a virtual file?

Take a look at the QResource class in Qt 4.2:

It looks like QResource is useful to load a complete resource file system
from external file... And I don't get how to make such file...
But I need to add file to already existed resource FS.
Something like
Q_INIT_RESOURCE(MyPermanentResource);
{
QFile *file = QFile(":/document/newfile.jpg");
file->write(decoded_buffer, buffer_length);
file->flush();
}
QLabel *label = new QLabel(this);
QLabel->setPixmap(QPixmap(":/document/newfile.jpg"));
How to rewrite file creating block to make this program work?
Any example code would be much appreciated.
