From 27ea5a65dd3fdabdad1569f5330f90248cdca4f5 Mon Sep 17 00:00:00 2001 From: David Faure Date: Mon, 25 Jun 2018 15:50:35 +0200 Subject: QAbstractItemModelTester: fix out-of-bounds index() calls When removing rows, the tester is looking at the data of the row "just before" and the row "just after" the removed rows, to see if they are still the same at the end of the removal operation. Guard this with bounds check, in case there is no row just before or just after. This is the opportunity to use modeltester in tst_qidentityproxymodel, which was already a testcase for removing the only row in a given parent.
