When adding the comic applet by DnD from the widget explorer to a containment, there is no problem. Trying to add it instead by double-click on the item in the widget explorer results in an applet added with an error symbol and the text "Error loading Applet: package inexistent. ". Which poses a bigger problem when trying to add a widget to a panel, because there is no DnD alternative (well, still possible to first create the applet on a containment and then DnD it onto the panel, but... it should just work). Found while discussing the C++-based Weather applet port which has the same problem (cmp. https://git.reviewboard.kde.org/r/127193/), which lead to the assumption it might be C++-based applets specific. "perhaps the setup applet scripts or so aren't run properly" was one assumption. Reproducible: Always Steps to Reproduce: 1. Select "Add widgets..." on panel or containment 2. Double-click "comic" item Actual Results: Applet with error symbol and the text "Error loading Applet: package inexistent. " is added. Expected Results: Comic applet instance is added.
The same also seems to affect the system tray, where adding a widget by checking it in "Additional Entries" leaves you with a blank space where the applet would be.
Git commit 40b99a91222f59a6172b8673536c3c15c0458bf6 by Marco Martin. Committed on 29/02/2016 at 16:31. Pushed by mart into branch 'master'. if path is passed, pick the tail PluginLoader::loadApplet works both by passing a simple plugin name and a full path of a plasmoid package. However, when loading the optional C++ plugin, we have to look in the standard plasmoid plugin path, so only consider the tail of the path name, as is guaranteed that part is equal to the plugin name.
