[pygtk] [on gnome] finding registered applications + icon(s) for MIME type

[Lara Michaels]

Hi Osmo,

Many thanks for your excellent help. That works perfectly for my purposes. 

Just one question: how can I find out which *command* (not just the name of the executable) gets executed when I use one of those applications returned by gio.gio.app_info_get_all_for_type?

In GNOME vfs, I got back a structure in which the third element was the actual command string, eg:

> app = gnomevfs.mime_get_all_applications('text/plain')[1]
> print app[2]
wine start /ProgIDOpen txtfile
>

I thought that in GIO get_commandline() [http://library.gnome.org/devel/pygobject/stable/class-gioappinfo.html#method-gioappinfo--get-commandline]  would do that for me, but I can't seem to get it to work on Python:

> app = gio.app_info_get_all_for_type('text/plain')[1]
> app.get_commandline()
AttributeError

In pygtk how can I get the command that is run when this app is used to launch a file?

Many thanks for your help,

lara
