Yes, that seems to work. Thank you.


File watching for the wallpaper would be an interesting course of action, but I
think that'll just spend additional system resources for little benefit. Unless
there's a non-polling, easy-on-disk/cpu-usage file watching solution that
exists?

Perhaps we could just have Plasma reload the wallpaper image every
(configurable) N seconds?


Notes
-

If one sets the image to a non-existent one, inaccessible one, or just an empty
string as given above, Plasma simply keeps using the wallpaper it had
previously, until a valid image is set.

I haven't tested what happens if you delete the image set as wallpaper, and
then restart the computer or log-out-log-in. Probably a blank wallpaper will be
displayed.

>d.writeConfig("Image", "file:///home/USERNAME/test.png");

That as Rex says, will just no-op. Changing that is not an option.

However, we can agree there should be 



Does 

writeConfg("Image", "")
writeConfg("Image", "file://blah")


work? 

It'll be only one sync.

Failing that maybe we can look at putting file watching into the wallpaper.

I suspect one possibility this doesn't work is because the config doesn't
actually change, so it's not reloaded.

If so, a workaround is to use a differently named file each time, that should
help ensure that 'writeConfig' actually changes
