Story:

I had Clion downloaded from source onto my computer sometime back. Now I technically don't use C/C++ anymore, so I deleted the source folder. But the launcher is still in the Whisker Menu:

Whisker Menu

Now it's a icon-less, empty launcher.

Question:

How can I get rid of this redundant launcher?

Could you see clion in ~/.local/share/applications? If you can, you need to erase the folder or file.

XFCE4 launchers appearing in Whisker Menu can be gotten rid of in two ways. If you never want to see a launcher again, choose the remove file option. However if you just want it to not show up but consider seeing it again in the future, choose the hide launcher option.

  1. Remove the configuration file which is read by Whisker Menu in every menu opening (xfce4-popup-whiskermenu). The configuration file is a plain/text file with a .desktop extension usually.

There are two possible locations to delete such files from (that I know of):

Non- Linux Mint user: ~/.local/share/applications

Linux Mint user: /usr/share/applications

  1. Hide the launcher from the Whisker Menu using the Application Finder (xfce4-appfinder). To do this, search for the launcher using Application Finder, use right-click on the resulting menu item and choose the Hide option. This is achieved by appending a Hidden=true line to the launcher's configuration file. Therefore, to unhide a launcher, simply remove said line from the configuration file.

Note: hiding a launcher simply means it won't show up in the Whisker Menu, whereas removing the launcher is done by removing a file.
