Qt background-image shows in designer, but not in release

Question

I have a simple Qt GUI application and am having problems adjusting the background of the image. The background image is displayed correctly in the form editor / designer, but when I run the application, the background image is missing.

Resource file:

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

Here's what it looks like in the editor:

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

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

The stylesheet for the widget (just to see if the background color works, because I assume that something is wrong with my resources):

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

And this is the end result when the application starts:

I assume that the assembly cannot access the background image resource, but I have no idea why. I also tried to apply the general background-image property in the Window0 stylesheet, but it doesn’t change anything (for example, if the main window was rewriting the background, but it looks like it is not).

Read the article on deploying the application in the Qt helper. I think you do not have image plugins on the target computer. Folders / folder images and your exe should be in the same directory.
