Control Functions would need to be:

chooser preference, so that might have to just be a string for now?)
We don't have a directory chooser, but that's a very good idea. Perhaps
something for 0.40.
If I understand right each of these functions would need to happen
inside a control, not possible from a display. Is that correct?
Yes. That's correct. Basically display-files can't do anything that is
not (a) done through the ADL-language (the xml you use to define the
displays), (b) done through a control, (c) built in Python (the stuff
you get when you do python -i and don't import anything)
I browsed through the controls on the site and I didn't find any that
appeared to help with this. Is there anything out there that I should
Can't think of anything if you found nothing on the official site
(gdesklets.de) or on the archive that can be found through the official
Finally, if I have to make a control, I'm thinking it should be called
something like ImageManipulation. Methods could be added do resizing or
transitions later down the road.
Sounds very reasonable. First I'd start thinking about the
property-based control interface. For the requirements you mentioned
earlier, I'd say you need something like this (just an example):
image_uri <- set this to the target image...
meta_data <- ... and then read this to get the meta-data in a dictionary
pictures <- get/set to manipulate the list of pictures
start_slideshow <- start a loop do show pictures
next_picture <- switch to next picture manually
prev_picture <- ....
Then you just build the functions that handle getting and setting those
If you have any questions feel free to post them on the list!
