Re: [Interest] QColumnView and QTreeView using same model
I have found when I use a custom model, most issues using views, are tied to an issue of some corner case condition in the model not being handled correctly. ~~Scott Original message From: Michael Jackson Date: 5/3/22 3:05 PM (GMT-08:00) To: Scott Bloom , Qt Interest List Subject: Re: QColumnView and QTreeView using same model No idea that existed.

[Interest] Issues with latest Qt MaintenanceTool and Kaspersky
Hello Qt Team, I just ran the updater using the MaintenanceTool. After the update, the MaintenanceTool got listed as malware by Kaspersky Anti-Virus and removed from the system. Refer to the screenshot below: [image: image.png] [image: image.png] I have been using both Qt and KAV together for the last several years without any issues. Are *deferredrenamekERbOS.vbs* and *deferredrenameQIoNFA.vbs* included in the MaintenanceTool package? Why suddenly did the anti-virus start listing it as malware? Has anyone else observed this? Thanks & Regards, Nibedit ___ Interest mailing list Interest@qt-project.org https://lists.qt-project.org/listinfo/interest
