Description Lynne Kues CLA 2002-05-27 18:05:20 EDT 
Working on PR 16797.  Got rid of my unnecessary setRedraw calls.  I am still 
seeing some flash with respect to the grippers.  Run the attached test case:

1.  Move the last cool item over to the left.
2.  Press Delete/Add button.  This deletes the last coolitem and adds a new 
coolitem at the end.  Notice the flash (mainly the grippers).
3.  Lock the coolbar.  Press the Delete/Add button again.  Notice no flash.

Note that I am on Win98.  Haven't tried the scenario on other Win platforms.

Comment 2 Felipe Heidrich CLA 2002-07-09 11:30:30 EDT 
Note: setRedraw for CoolBar has been fixed.
I've tested your code surrounding the add/delete action with setRedraw(false) 
and setRedraw(true). Doing this there's no more flash.

Please, can you do your own tests and then closed this PR ?
Comment 3 Lynne Kues CLA 2002-07-22 18:24:33 EDT 
Running the test case, you can very easily see the gripper flash.  
Adding/deleting an item should not affect grippers on other items and setRedraw
(false/true) should not be necessary.  Why is the flash occurring?

Still flashing in RC1.
Comment 5 Mike Wilson CLA 2008-04-12 15:57:09 EDT 
Closing for lack of activity. Please re-open if there is any expectation that we will ever do this.
