Configuration of dde-control-center and ramdomico wallpaper

[talesam]

I am a BigLinux developer and we are creating a DDE version, but due to lack of documentation some things that are simple become complex.

• When I activate the default image app in the control center, in which file is it saved? I couldn't figure it out, the default image app isn't set, so I need to leave it set.

• By default the theme and wallpaper are automatic, I believe I managed to leave the theme set, but the wallpapers always change automatically, how can I disable this?

Emm, it saved in dconfig, and a json file under ~/. config/dde-appearance I think, there's a repo about theme, the files named as "theme.ini" record the wallpaper location , what I remember is like this
