Qt background-image shows in designer but not in release

[cenarius2]

I have a simple Qt GUI application and I am having trouble setting the image background. The background image displays properly in form editor/designer but when I run the application there is no background image.

Resource file:
@<RCC>
<qresource prefix="/">
<file>eb_back_small.png</file>
<file>favicon.ico</file>
<file>background.jpg</file>
</qresource>
</RCC>@

This is how it looks like in editor:

Style sheet for centralWidget (background.jpg is a simple 500x350 red image):

@#centralWidget {
background-image: url(:/background.jpg);
}@

Style sheet for widget (just to see if background-color works because I assume something is not right with my resources):

@#widget {
background-color: rgb(0, 170, 0);
}@

And this is the final result when I run the app:

What is the problem?

hi cenarius2

you also maintain background.jpg file in release with app.
bcoz, designer is only dynamic viewer of application skeleton ,
not a app builder.
