QtCreator: resource retriever empty?

[myoan]

Hi all,

I'm creating a Qt4 app with QTCreator and I woul like to set an image to a button.
I first created a resource file using the GUI and I added some images. Then I open the UI Editor and try to attach this image to a button. The thing is that the resource retriever remains empty, even clicking on the "refresh" arrow, restarting Qtcreator, restarting my PC and everything does not solve the problem, my qrc is filled but the resource retriever empty!

What am I doing wrong?
Many thanks
