Can't load text file from .qrc

kitfox

I've created an xml file that I'd like to be able to load from a .qrc file, but it's not working for some reason.

My qrc file is in resources/mainresources.qrc and I seem to be able to load icon images from it fine. For example, QIcon(":/icons/toolBrushVector.svg") can be used to draw an icon.

I've created a file called mainmenu.xml and placed it under resources/. I then added an entry to the qrc index:

</qresource>
    ....
    <file>mainmenu.xml</file>
</qresource>

I then attempt to load the file into a string like this:

QFile file(":/mainmenu.xml");
QTextStream in(&file);
QString xmlStrn = in.readAll();
file.close();

Unfortunately, xmlStrn keeps being set to "". What can I do to load my xml file?

Looks like the problem wasn't with the qrc. I needed to load the text like this:

QFile file(":/mainmenu.xml");
file.open(QIODevice::ReadOnly);
QString xml = file.readAll();
file.close();

@kitfox You can use QTextStream, but you have to open the file first:

QFile file(":/mainmenu.xml");
if (data.open(QFile::ReadOnly)) {
    QTextStream in(&file);
    QString xmlStrn = in.readAll();
    file.close();
}
