I wish to drag files from Nautilus onto a certain executable (.desktop file) in my Unity quick launcher (so that the executable file will run with the path of the dragged file as its first argument).

I find this behaviour works fine when I drag a file from Nautilus onto the .desktop file in another Nautilus window, but when I try to drag the file onto the quick launcher, my executable becomes disabled. Is there a remedy?

  • What you're showing on the screenshot is pdf file, not .desktop. Simply dragging and dropping to launcher should work. I've several .desktop files that I pinned to my launcher by the same method – Sergiy Kolodyazhnyy Aug 12 '15 at 0:15
  • @Serg, I'm not trying to drag a .desktop onto the launcher; I'm trying to drag a data/text file onto a .desktop (executable) file in the launcher. – JellicleCat Aug 12 '15 at 0:42
  • OK, I see what you mean. Is there a particular program that doesn't work or just all programs on the launcher don't allow dragging and dropping ? I've noticed although LibreOffice Writer doesn't light-up with I drag text files onto it, but it still does open the file i dragged. Have you tried dropping the file onto the icon despite it not lighting up ? – Sergiy Kolodyazhnyy Aug 12 '15 at 0:48

    Only launcher items that have the same mimetype in their .desktop file as the file being dragged will stay active. To see with a .pdf add evince (Document Viewer) to the unity launcher, when dragging a pdf it will remain active. So check the Mimetype= line in the .desktop of the launcher item you want active for pdf mimetypes listed (or any other file/mime – doug Aug 12 '15 at 14:09
  • Thanks, @doug. I added MimeType=text/*;application/*; to my .desktop file, and it now supports drag-and-drop for the files that I wanted. – JellicleCat Aug 12 '15 at 15:57
