[gtkmm] custom treemodel

[Sverre Sundsdal <sundsdal idi ntnu no>]

Hi

I am new to gtkmm, so maybe this has been asked before, but I couldn't 
find anything in the mail archives.  I am using a TreeView to display 
some constantly changing data. I have a class that contains this data in 
getset methods. The library i have created takes care of updating the 
data. Now, what I would like is aTreeView to reflect this data, which is 
contained in a vector.
I have some problem figuring out how to proceed.
All TreeView examples I can find uses a ListStore and copies the data 
from the datastructure to the liststore. I figure that this requires a 
thread to copy over the data from the vector to the liststore. Then you 
would have two copies of the data.
I don't think this is the correct way to do this, but I don't know how 
to do this better.  Maybe a custom treemodel? 
Has anybody out there done this before and has som example code I can see?

thanks in advance.

They say that if you play a Windows CD backward it plays satanic messages. 
That's nothing, if you play it forewards it installs Windows!
