Sign me up, but I'm not sure how much help I'm going to be.  While
we're on this topic, I'm totally stumped on one area of list views.  I
can see how we can identify the line numbers selected, but how on earth
do I extract the data contained in the selected line?  I keep getting
machine-level exceptions, so I know I'm doing something wrong.

Here's a patch to fix the problem. It's not clean, but it works. 
I'll try to come up with something better asap.
Add the following code to tree_selection.gtk:

constant get_data = define_c_func(GTK,"gtk_tree_model_get",{P,P,I,P,I},P)
constant col_type = define_c_func(GTK,"gtk_tree_model_get_column_type",{P,I},P)

--------------------------------------------
global function GetRowData(atom selection)
--------------------------------------------
integer cols, model, iter
object result, item, data

if gtkGet(selection,"Count") < 1 then 
   return NULL
end if

result = gtkGet(selection,"Selected")
model =	result[1]
iter = result[2]

cols = gtkGet(model,"N Columns")
data = repeat("",cols)
item =  allocate(4)
poke4(item,0)

for x = 1 to cols do
 result = c_func(get_data,{model,iter,x-1,item,-1})
 if c_func(col_type,{model,x-1}) = gSTR then
    data[x] = deallocate_string(peek4u(item))
 else
 data[x] = peek4u(item)
 end if
end for

return data
end function

You can then call this as follows:

-----------------------------------------
function ShowChoice()
-----------------------------------------
object result

-- only works if selection_mode is single;
result = GetRowData(selection)
pretty_print(1,result,{2,0})

return NULL
end function
constant show_choice = call_back(routine_id("ShowChoice"))

Yes it is, but follow the link to my home page for the Windows version.
It has a few bugs related to file paths to be fixed before I put it 
on Sourceforge.

After changing gtkGet to get, it worked great.  I had some charset
issues from copying between email and Kate, but once I cleaned that up
it was fine.  Has there been an update to the library changing get to
gtkGet?  If so, I'll need to d/l the update.
