QResource::registerResource and "mapRoot"

TheTux

Hey

I'm experiencing a weird behaviour with QResource::registerResource, using the second argument "mapRoot".

"QResource::registerResource(const QString & rccFileName, const QString & mapRoot = QString()) "

Not sure if it is the expected way it should work, but when I'm trying to mount a dynamic resource file at the location specified by mapRoot, registerResource is registering my data at ":/" as well.

This is a problem for me because I have others resources registered at ":/" and I don't want them to collide with the newly registered resources I'm trying to load. The documentation is not crystal clear about this behaviour.

Here is a test code:

qDebug() << QResource::registerResource("test.rcc", "/foo/bar");
qDebug() << ":/img/Dealer :" << QFile::exists(":/img/Dealer");
qDebug() << ":/foo/bar/img/Dealer :" << QFile::exists(":/foo/bar/img/Dealer");

The output is:

true
:/img/Dealer : true
:/foo/bar/img/Dealer : true

So my question is, is it the expected behaviour or something is buggy there ?

Hi and welcome to devnet,

Are you by any chance also building that rcc file in your application ?

Hi and Thank you,

No i'm building it apart with rcc -o, it's not a part of my building chain at all.

But maybe you have it added to your .pro file under RESOURCES?

My main project where I spot the issue is managed with cmake, and I don't ask for any build-in resources.
My test project (code above), is built with qmake, the .pro is pretty straightforward :

QT += core

QT -= gui

TARGET = TestRegister
CONFIG += console
CONFIG -= app_bundle

TEMPLATE = app

SOURCES += main.cpp

OK, that pretty much rules out the possibility that Qt automatically picked up your resource.
