QTreeWidget single-selection issue

6 years 9 months ago #1 by 无锡飞谱电子信息技术有限公司
QTreeWidget single-selection issue was created by 无锡飞谱电子信息技术有限公司
in code QTitanRibbon-4.14.0 with Qt 5.8 by VS 2013 in win10 64bit platform.
When in single-selection mode, two tree item can be displayed as selection in QTreeWidget.

The method to re-produce this issue:
1: open the example project in the installation directory qtitanribbon.pro
2: use the OfficeStyleWIdgets project
3: change the following code as below:
void TreeBoxDock::createWidgets()
{
QTreeWidget* treeWidget = new QTreeWidget;
// Comments out
//treeWidget->setAlternatingRowColors(true);
// Switch it to single selection mode
treeWidget->setSelectionMode(QAbstractItemView::SingleSelection);
treeWidget->setSelectionBehavior(QAbstractItemView::SelectItems);

and then build and run it, and try to select the different tree items many times, you will see two items are displayed as selection in UI. In the attached picture, the item2 and Item4 get displayed as selection.
