Change Deepin Background / Wallpaper with Wally in Archlinux

When i want to change the background in Archlinux, there's no option to add more wallpaper or picture into Deepin Desktop Environment. But i found a app that can help to change background in Deepin Desktop environment. It is Wally, wally is a desktop background / wallpaper changer for QT4.

The source code is here:

https://sourceforge.net/projects/wally/

In archlinux, it's available on AUR:

https://aur.archlinux.org/packages/wally/

There's no menu for wally, so run at command line:

$wally

Then it will appear on panel, right click on wally, then go to settings:

Then choose folder, and add your background/wallpaper folder, set the position then ok:

Right click again on Wally menu then choose play, and just next to choose the wallpaper, here's the results :

it will be also appear on your Deepin wallpaper list
