I'm writing a logging application which is using a QListView with custom QStandardItems to display the log data. I have implemented filters in the app that will color the matching rows differently and when changing a filter I have to manipulate every item in the list, which after a while gets very slow. I'm not sure what's causing this yet, but I wonder if it could be that it repaints after every item change. If that is the case, could I somehow tell QT to not repaint until I'm done manipulating all the items?
Thanks for any help!
For helping others, I could add that I fixed this by implementing my own view that handles the paint event itself and only paints the rows currently visible on screen. This makes it extremely fast and no internal QT view seem to be able to do something similar.
