Using Elementary OS 0.3.1 Freya 64-bit.

I use an app called Isoplex. It's run directly from an executable which I have stored in the Downloads directory. Runs just fine by double clicking on the file from Files.

How do I pin this to Plank? The icon appears while running Isoplex, but right-clicking doesn't let me pin Isoplex to Plank.

Is there a way to do this? Alternately, can I add Isoplex to my Applications list in the upper-left corner? Thanks.

Create .desktop extension file in ~/.local/share/applications. For example:

scratch-text-editor ~/.local/share/applications/isoplex.desktop

And write this in there:

[Desktop Entry]
Exec=command to run here
Name=visible name here
Comment=comment here
Icon=icon path here

You must manually find and assign it the path to the executable file, and the icon. Don't forget to make the file executable (chmod +x ~/.local/share/applications/isoplex.desktop).

Then you can drag&drop the desktop file onto Plank or launch it from Slingshot and then 'Keep in dock'.

  • Okay, everything went okay, but I don't see any way to get scratch to save the file. Is it saved when I close scratch? The icon doesn't show up on the panel. Sigh. Commented Oct 14, 2015 at 0:43

    @JeffreyNeedle Yes, Scratch saves files when changing. If you did everything correctly, the icon should appear in Slingshot (applications menu). Place your result (isoplex.desktop) on Pastebin.
