Description ParsaMousavi 2020-07-13 16:54:49 UTC

When I drag an image from Dolphin and drop it into the desktop area and then click on the "Set Image" option , the wallpaper doesn't change at all.I get the following messages from the output of the "plasmashell" command in terminal after doing that:
```
Arrived mimeData (QUrl("file:///dragged_image_URI/Cloud%231.jpg")) ("text/uri-list", "text/plain", "application/x-kde4-urilist") at 912 ,  12
Mimetype Job returns. "image/jpeg"
Received a suitable dropEvent at  QPoint(912,12)
Bailing out. Cannot find associated dropEvent related to the TransferJob
Creating menu for:  "image/jpeg"
QMetaObject::invokeMethod: No such method StackView_QMLTYPE_127_QML_128::setUrl(QVariant)
```

After that the desired image gets to the list of the recent wallpapers in the "Desktop Settings --- Plasma" window (right-click on the desktop->Configure desktop) , but I'm also unable to set the wallpaper by the means of that.


STEPS TO REPRODUCE
1. Drag an image into the desktop area from the file-manager
2. Click on the "Set Image" option from the appeared drop-down menu

Revert "[wallpaper] Drop unused method"

This reverts commit 221a3a52223d90bdbe514d715732cfcd6fdb7abd.
This method is actually called by WallpaperInterface for drag and drop.
