Performance

[Horst Gassner]

Hi all!

I have implemented a tree view with special items (the base for this
work was the TreeWidget from IDLE).

The performance is not the best and therefore I ran the profiler today.
The following function is one of the slower ones and I would be happy if
there are any possibilties to speed this thing up.

subItems = {}
if s.__subList[level] :
	for key in s.__subList[level].keys ():
		# root level is special case!
		# get all sublevels without recognizing id of sublevel
		if level==0 or string.find(key, id) == 0 :
			subItems[key] = s.__subList[level][key]


The functions looks for all subitems for a given level and a given id.
For each level I have pre-built a list that I have just to go through
the items of the given level.

Thanx in advance
Horst
