Re: TreeView: Multiple selection inefficient?

[Matthias Kaeppler <nospam digitalraid com>]

Okay, since it has not been gotten any better by all changes I have 
made, I have now completely commented out the signal handler connection 
and the performance hit is still there!

That can only mean that Gtk+ is also calling its signal handlers (of 
course it does, how should it otherwise visually select a row) and those 
are already the performance killers.

Just try it:
Fill a tree view with e.g. 2000 entries, select the first and hold down 
or page-down till you reach the bottom and you'll see the program 
doesn't react for several seconds because it's still computing something 
(probably calling a huge bunch of signal handlers).
