add program to 'open with'-dialog

[mito-o]

hey there,

i'm using xubuntu 14.04 with the standard file browser. i installed mtPaint and found that there is no entry in the 'open with'-dialog.
i didn't want to make mtPaint to be my standard-program for opening images, i just wanted to add it to the list in the 'open with'-dialog.
so my question is: where can i find the file for adding the program?

i additionally have to say that i solved the original problem by first making mtPaint my favorite program to open images and then
changing back to the other program, but i still want to know where i can add programs 'by hand' - just for being a better unity with my system, you know? ;)

thanks for for your help

The problem is the desktop file for mtPaint lacks MimeType information. Compare it e.g. with GIMP and Ristretto:

grep -s ^MimeType= /usr/share/applications/{gimp,ristretto}.desktop
I don't know for sure what image types mtPaint is able to handle, thus the MimeType line I add in the next workaround is pure guess. Tweak it accordingly.


mkdir -p ~/.local/share/applications
cp /usr/share/applications/mtpaint.desktop !$
echo 'MimeType=image/png;image/gif;image/jpeg;image/jpeg2000;image/bmp;image/tiff;image/x-xpixmap;image/x-xbitmap;image/x-targa;' >> !$
update-desktop-database !$:h

After that, mtPaint should show up in the Open with... list.

Don't forget to file a bug report against mtPaint for its lack of MimeType information. It's a universe package unchanged by Ubuntu, so better do it directly in Debian BTS (https://bugs.debian.org/cgi-bin/pkgreport.cgi?src=mtpaint), not in Launchpad.

If you decide to file a bug then wouldn't hurt to add that for Gnome it needs a %<letter> added to the Exec= line in the .desktop or it will never show up in a gnome3 based install
Ex. -

Exec=mtpaint %f

I had the same situation: I wanted to have Shoutcast Playlists open with Geany from the "Open With.." dialog, but not set it as default.

Edited ~/.local/share/applications/mimeapps.list

Added the section "Added Applications" (if may be already present) and my desired association (in red).


[Default Applications]
text/plain=mousepad.desktop

[Added Associations]
audio/x-scpls=geany.desktop;

Geany now appears on the "Open With..." dialog, but not as default.

Reference system: Xubuntu 14.10
