Description nadaschauher 2002-12-18 19:02:38 UTC 
I've noticed that inserting items into a sorted treeview is extremely slow.
There seems to be no reliable way to temporarily disable sorting while
inserting a bunch of new items except deleting the Store, populating a new
one and attaching that. The speed penalty is enormous, I estimate my test
application to insert at least 10 times slower on the sorted treeview.

There should be a function to temporarily disable sorting, in order to
insert larger amounts of items. Even better would be one that completely
freezes the state - visual representation, sorting info, etc. - of the tree.

Applications with big lists suffer badly, Rhythmbox is an example.

That inserting items in a sorted treemodel is slower, is a known fact,
because you have to use insertion sort (which is O(n) IIRC).  We can't
really change anything there.

So basically you are asking for a function to temporarily disable sorting.

Marking as DUP of a "can't disable treemodel sorting" bug.
