Description Pascal Rapicault CLA 2010-05-17 16:29:00 EDT 
When I browse the helios repository and select a category, the time it takes to enable the check mark seems rather long compared to selecting something in other places in the eclipse ui.
Therefore I'm wondering if there is not some heavy computation going on.

I observe:
- it's slower if you do it without the category expanded (this isn't too shocking I think)
- it's still "heavy" feeling once items have been expanded.  One can definitely see that the check mark of an expanded category is taking longer than the corresponding uncheck mark.  

I suspect somewhere someone is going to the content provider for children (which does a query) rather than just manipulating the viewer model

it also feels like there's a defer redraw in play.
If one were to see the checkmarks ripple, it would feel faster than having a subsecond-pause followed by the appearance of all checkmarks.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
