QT5.2 Resource files - c++

Question

Short yet annoying problem; I can't access anything defined within qt resource file (aka .qrc). I've followed the qt utorial for creating a widget application called TextFinder.According to it I've created all the necessary files and completed all the instructions yet I can't access the qrc contents.
Inside the project folder I have files like:
TextFinder
resources
input.txt
main.cpp
textfinder.cpp
textfinder.h
TextFinder.pro
TextFinder.pro.user
TextFinder.qrc
textfinder.ui
The contents of the qrc file is as follows:
<RCC>
<qresource prefix="/res">
<file>resources/input.txt</file>
</qresource>
</RCC>
To access the file within I opened the qrc in Editor right clicked on the file and chose copy resource path to clipboard option. This produced ":/res/resources/input.txt". So I just entered this to my function to open the file. This function looks like the following:
void TextFinder::loadTextFile()
{
QFile inputFile(":/res/resources/input.txt");
inputFile.open(QIODevice::ReadOnly);
if (inputFile.isOpen())
{
QTextStream txtStream(&inputFile);
QString contents = txtStream.readAll();
inputFile.close();
ui->textEdit->setPlainText(contents);
QTextCursor cursor = ui->textEdit->textCursor();
cursor.movePosition(QTextCursor::Start, QTextCursor::MoveAnchor, 1);
}
else
{
throw std::runtime_error("Resource file may be wrong?");
}
}
When I run the application the runtime_error is thrown that tells me that it couldn't open the file. In the project file I have the qrc file defined as follows:
RESOURCES += \
TextFinder.qrc
What is going wrong in here? Anyone could point out what i'm doing wrong?

According to Qt Resource System documentation:
It is also possible to specify a path prefix for all files in the .qrc file using the qresource tag's prefix attribute:
<qresource prefix="/myresources">
<file alias="cut-img.png">images/cut.png</file>
</qresource>
In this case, the file is accessible as :/myresources/cut-img.png.
So subpath is cut off when prefix is present
