fast gtkmm widget displaying list ???

[Dimitri Holz <d holz innoventis de>]

Hello everybody,

I'm looking for a fast gtkmm-widget which can display a text list whith
icons and expanders with information inside it, like treeview. I always
tried it with treeview, but treeview is able to load 1000 rows per
second on my pc and I need to load 20000 rows per second. I have windows
xp and when I write a .NET application and use .NET-treeview it works
(it loads 20000 rows/s), but I don't wont to develop application with
microsoft.NET, I prefer Gtkmm.

I noted that when I load a row into gtkmm-treeview, that a resize-signal
of Gtk::Window object how added the treeview, will be setted. Propably
this is one of problem? (20000/s setting signal -> redrawing whole
window 20000/s). What does treeview doing each time when an row added,
maybe there something what I don't need but it uses much of cpu-speed or
so? Is it possible to create 20000 whole rows where nothing will be
displayed and refreshing them by loading rows, maybe this can speed up?

To all gtkmm-experts, please help SOS
