Background-image || Border-image not working

[QSourceCreator]

I'm building an application on Qt and I want to give a background image to the application. When I'm programming in my house, this piece of code works but when I make it in other place, this background image stops working...

this -> mainWindow -> setStyleSheet("QMainWindow { \
                                            border-image: url(:/resources/BackGround.png) 0 0 0 0 stretch stretch; \
                                     }");

Somebody can help me? Thanks BTW.

@QSourceCreator
Are you absolutely sure that your built executable image contains the specified resource? You might verify by trying e.g. QPixmap pixmap(":/resources/BackGround.png"); and verifying !pixmap.isNull() at runtime in your code run on the other machine.
