Using resources in style sheets

Qt provides us with a platform-independent resource system that allows us to store any type of files in our program's executable for later use. There is no limit to the types of files we can store in our executable – images, audio, video, HTML, XML, text files, binary files, and so on are all permitted.

The resource system is really useful for embedding resource files (such as icons and translation files) into the executable so that it can be accessed by the application at any time. To achieve this, we must tell Qt which files we want to add to its resource system in the .qrc file and Qt will handle the rest during the build process.
