I tried to make an app with a background image. I can see how I can define the background with the stylesheet tool (changing the background color is ok, thank you) but...
In order to use a background image, the image apparently has to be specified as a Resource. In the Qt Designer doc it says that in order to add resources to your project, you must enable the Resource browser in the tools menu. Call me blind, but I can see no such option on the tools menu?
