I mailed him the other day and nobody else had complained about it
:-). The problem is that we set different attributes for every cell.
I have experimented with using a hash table for the attributes in
gtksheet.
Timing for starting the p18c252 using a P233:
18 seconds using gtk+extra-0.99.0 (I have a slow graphics card)
9 seconds using gtk+extra-0.99.1 ((non-released) has redraw fix plus
some other stuff)
1 second using gtk+extra-0.99.1 + hash patch
I wonder how it scales up to the 2000 rows in the imagined program
memory viewer, but at least this improvement makes it _thinkable_ to
add all memory in one sheet.
