Those style-properties aren't properties. Properties are associated with
object instances, whereas style-properties, when they are invented, are
targeting at classes of widgets. The GTK model is different from our
intuition here. That's why they are so awkward to use. I've never found
any easier way of using them.

For regular properties, you can definitely do so. For example,
Gtk.Label label = new Gtk.Label("hola");
label.text = "hello";

TreeView is the most difficult widget in GTK. Given the fact you are not
yet familiar with the GLib stuff at all, I would say you were choosing
the steepest cliff. Did you read the GTK tutorial? I would recommend you
translate several examples with Vala to make sure you are familiar
enough with the language and the toolkit first.

There is one powerful tool. It is called Glade-3. Then you gonna take a
grab of GtkBuilder and the XML(GMarkup).

Freedom is not free... It costs one hour oh five.
If you are prototyping for a company, I would sincerely suggest you
should also take a look at Mono(Sharp on Linux); it is also promising.
MonoDevlop is mono's IDE; not productive yet as I learned from the net.
but I do think they already have auto-completion: it is a must for a
product toward the professionals.

it is written in Gtkmm though.

The trilogy of GtkTreeView GtkTreeModel and GtkTreeStore definitely has
confused you. Refer to
http://en.wikipedia.org/wiki/Model-view-controller
and
http://blog.riff.org/2006_10_15_grokking_phpgtk_gtktreeview_and_friends
gtk-app-list will have the people that can answer you these questions
about TreeView. To me, TreeView is VERY frustrating to work with in
either C or VALA, because of the very complicated nature of visualizing
a multi-column tree.
Looks like you are trying to make a highly decorated GTK app. Most of
the GTK apps I use have no background image, nor customized background
color, nor customized widget border width or color.

Sorry but I am a vim. There is plenty of valide users here though.

I did write some simple tree view half a year ago but I did never go
into that deep. I don't know if any other people used TreeView with
VALA. Nautilus, Evolution, RhythmBox, Epiphany all have fancy treeviews.
They are all very well written in C; it shouldn't be difficult to
convert any of their code into vala.
Good luck!
