libseed-list seed && GtkTreeSelection

[tsr <tsr offentlig tsr se>]

Hi,

First off, I don't know much of JS or Gtk but still I'm trying to use
seed to create a basic desktop editor.

(I've chosen this combination cause I hope to eventually be able to
replicate it for the web later on and using JS for the logic in both
places might save me some coding - that is the idea anyway)

Anyhow, I've managed to set up a GtkTreeView that recursively displays
the files and folders from a given folder. I have also managed to catch
the event of one row being selected. Now I have trouble using that
select-event to show the contents of the file (/folder) in a separate
panel.

Below is my code (I've built the interface with glade, so I think you
should be able to follow my intentions without a full glade file)

The problem is dealing with the
Gtk.TreeSelection.get_selected()-function (see the show_file-function
below). I don't understand what the first argument should be, I've tried
almost any combination of things but I (almost) always get:

(seed:17195): GLib-GObject-CRITICAL **: g_object_get_qdata: assertion
`G_IS_OBJECT (object)' failed
Fallo de segmentación (in english: ~ segmentation fault)

I've installed seed from the ubuntu-repos and they show version 2.28
(haven't dist-upgraded from Jaunty)

If you need any more info to be able to help me I am ofc willing to give
that.

Oh, while I'm here, is there any generic way of getting information out
of seed_struct-object? It would help me to debug things and keep moving
slowly forward).

I am not on the list, so please cc me (but I will check the archives so
you don't have to).

/Tomas
