RE: Continue flame about WEIRD gtk2 design.

["Thomas Cameron" <tom ceisystems com>]

Maxim,

I'm sure that the reason these types of widgets are not included by
default is that the "average" programmer using GTK+ would not have a
need for a list 100,000 items in length.  Obviously you do.  If you wish
to write your own libraries because of these "missing" pieces in GTK+,
then by all means do so.

There is no disputing that GTK+ has its place in GUI development.  Can
it do _everything_ that _everyone_ needs?  No.  But what language can?
My suggestion to you would still be to develop your own widget to
display extremely large lists.  If you're interested in "optimal"
methods of using pointers to point to nodes, lists, or other structures,
then I suggest looking at the source for ReiserFS.  It has an extremely
fast organisational system, using a combination of linked lists and b*
trees.

Good Luck,
Tom Cameron

I'm writing using GTK about three years...

Why this widgets are not included by default? Why every time I need to 
hack gtk code
to rewrite widgeds for my needs? May be better in this case to write my 
own libraries :-) ?
Also I think that gtk+/glib developers can write widgets better than me 
due real undestanding
internals of both libraries.
I do not like to use glib by myself due nonoptimal solutions for misc 
structures (e.g. lists).

P.S. But in any case I think that GTK2 is GREAT STEP FORWARD comparing 
with GTK1.2.x.
