QResource register multiple resources, resource loading principle, which is the last available resource?

Question

Let's say I have 3 qrc files. The first 2 contain the same resource path and the 3rd one doesn't contain that path, for eg:

qrc1:

<RCC>
    <qresource prefix="/">
        <file>res/image.png</file>
    </qresource>
</RCC>

qrc2:

<RCC>
<qresource prefix="/">
    <file>res/image.png</file>
</qresource>

qrc3:

<RCC>
<qresource prefix="/">
</qresource>

Loading the resources is done as follows:

QResource::registerResource("qrc1.rcc");
QResource::registerResource("qrc2.rcc");
QResource::registerResource("qrc3.rcc");

so the rcc files are registered in the above order. So when someone tries to get qrc:/res/image.png, which file it will get? from the first rcc that contains the respective resource(from qrc1) or from the last successfully loaded rcc (from qrc2)? I couldn't find an answer in the docs.

My tests show that it takes the resource from the first successful loaded rcc, even though I was expecting to get it from the last rcc. What should I do in order to take the resource from the last successful loaded rcc? Any ideas? Did somebody understand the resource loading principle in terms of order? Thanks.
