[Qt-interest] QListWidget flickers for 1 to 2 sec when updating the QListWidget

[Trinathpujari]

Hi,

    I am using QListWidget for displaying the contacts in a call history 
from a linked list but when listwidget goes to maximum entries and after 
it updates the recent contact to the list .
    At this time the if the selected contact is the last contact in the 
list , then list widget flickers and it goes blank for 1 or 2 secs or 
when the user moves his scroll area in the list widget it goes blank.
    Please provide me some inputs if anybody knows how to update the 
QListWidget without flickering.

Regards
 Trinath
