Hi,
I have been trying to offer a theme selection in an application,
but I can't get the chosen theme to update the screen. I'm not sure if
I'd like it to update only the application it runs from or the whole
desktop theme, but if I could get at least get one of both working I'd
be happy. Ideally, I'd like to have a desktop-theme switcher too.
I have made a little example-app to test it. If someone could look at it
and tell me what I am missing it would be really appreciated.
Thanks a lot.
