[squeak-dev] Freeze when exploring Dictionary with nontrivial size :(

Hi list,

Loading the WordNet lex db into Squeak gives a Dictionary with some  
150'000 entries. When inspecting the dict then GC seems to get involved  
during scrolling :( even when no entry is selected.

But when exploring it, the first click just consumes CPU and alt-. shows  
debugger but the .image is already frozen :(

I can imagine that I'm not the first one who runs into explorer+dictionary  
freeze. Is there a cure, a fast+easy dictionary implementation for Squeak?

TIA

/Klaus

That's the way, I like it :) loads 147'306 String keys very fast (and  
doesn't freeze :)

Thank you very much Lukas.

I don't think the dictionary is the cause of this problem,
although it is a problem. I think the problem is the fact that
explorer tries to print every entry in the dictionary, convert
it to 150,000 TreeItemMorphs (or whatever the class name is), and draw
them, even the ones that are unseen. SimpleHeiarchialListMorph
is not very smart with big lists
