mime type not associating with gui application

[Erik Blankinship]

How do I create my spec file so that I my gui application can be launched by
double clicking a filetype it is associated with via mimetype?

This is what I've done so far:
- I have updated my .desktop file so that it
includes MimeType=application/x-supes-saved;
- In my spec I have successfully used xdg-mime and xdg-icon-resource so that
files with my custom extension (.supes) has my custom icon.

But when I double click on one of my files, I am prompted with a modal
dialog "There is no application installed for Superman Saved Game files".
 When I opt to "Select Application" my application is not listed either.
 (The application's desktop icon is successfully installed and runs under
the application menu).

Any suggestions?  Thank you.

bad.  xdg-* tools are intended for user-space, not system-space (ie, not 
to be used in pkg scriptlets).

See here for details,
https://fedoraproject.org/wiki/Packaging/ScriptletSnippets

sections on 'desktop-database', 'mimeinfo', and possibly 'icon-cache'

Thanks Rex!  I did not notice my icons and mime types associations were
being set on rpmbuild.  Now I have my application associated with my custom
mime-type using scriptlets.

However, I am not clear on how I am supposed to associate files with my
mime-type with a custom icon.

xdg-icon-resource made it pretty simple to associate an icon with a
mimetype, but if I am reading
https://fedoraproject.org/wiki/Packaging/ScriptletSnippets#Icon_Cachecorrect...,
I need to create an icon for every theme?  Is there a preferred
way to just set a custom icon for all themes?

Modified my .desktop file so that exec=/path/to/app.py %F

Now, when I double click on a file associated with my mime type, my
application comes up in the list of files I can associate with that file's
extension.

Is there a way to bind the extension and the application when my rpm is
installed?
