Qt has no dependences?

["BumbleBee"]

I made a qrc file.
It looks like this(added prefix and then images):

<RCC>
    <qresource prefix="/new/prefix1">
        <file>1.jpg</file>
        <file>ex.png</file>
        <file>o.png</file>
        <file>icon.png</file>
    </qresource>
</RCC>

<RCC>
    <qresource prefix="/new/prefix1">
        <file>1.jpg</file>
        <file>ex.png</file>
        <file>o.png</file>
        <file>icon.png</file>
    </qresource>
</RCC>

To copy to clipboard, switch view to plain text mode 

Then in .cpp file I call images like this:

QPalette palette;
    palette.setBrush(this->backgroundRole(), QBrush(QImage("1.jpg")));
    this->setPalette(palette);

QPalette palette;
    palette.setBrush(this->backgroundRole(), QBrush(QImage("1.jpg")));
    this->setPalette(palette);

Then,I save,build and move the exe alone to a removable disk.
And...It doesn't work.All the images don't show(like if the qrc doesn't exist..).I add the icons to the removable disk(near exe)and it works then...

In my main.cpp I have this:

#include <QtGui/QApplication>
#include "tictactoe.h"
 
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    TicTacToe w;
    w.show();
   Q_INIT_RESOURCE(icons); //My qrc file is: icons.qrc
           return a.exec();
}

#include <QtGui/QApplication>
#include "tictactoe.h"

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    TicTacToe w;
    w.show();
   Q_INIT_RESOURCE(icons); //My qrc file is: icons.qrc
           return a.exec();
}

Please help.
