How to set wallpaper for each virtual desktop via D-Bus?

[iamhyc]

Under the D-Bus interface "com.deepin.daemon.Appearance", there is only a read-only property for WallpaperURIs, but you could not set it.
So, is there a way to set the wallpaper for each virtual desktop?

Go on the virtual desktop where you want to set the wallpaper, right click from the mouse and select wallpaper from the menu. If you choose a wallpaper being on that desktop it will only set to it (not all desktops will have that wallpaper)

Yes, it can be set via mouse click. I just wonder whether there is an accessible API to do it.

I want to set the virtual desktop wallpaper via D-Bus or gsettings.

Hi @BLumia , could you invite some deepin developer to answer this?

[BLumia]

Sorry for the late reply. SetCurrentWorkspaceBackground under com.deepin.wm should be the one you're looking for :)

[BLumia]

Under com.deepin.wm there are a set of methods related to workspace background. You can use SetCurrentWorkspaceBackground for current workspace, and SetWorkspaceBackground for setting the background of the given virtual workspace index. You can use d-feet or qdbusviewer to find out other interfaces that you might interested :)

Got it. I did miss the SetWorkspaceBackground one.

@BLumia Just one more related question.
Why the first "workspace" is indexed with "1", instead of "0"?

It is not consistent with the "_NET_CURRENT_DESKTOP" value from x11. Is the idex 0 workspace reserved or for something else?

@BLumia Hi, I find SetWorkspaceBackground does not work correctly on 20.7.1.

I can check the wallpaper is already set via the "Get" method, but it does not take effect, i.e., the displayed wallpaper did not "refresh".

By the way, the wallpaper can be changed correctly via right click on the desktop.

Please help check if there is something wrong with the daemon. Thanks!

Not sure, it should work imo. I saw you reported a bug (#3505) and we'll check that out later :)
