Description
We create a QTreeWidget with setAnimation to true, and we add two top level items with 1 children in both of them; we connect the itemExpanded(QTreeWidgetItem*) SIGNAL with a method that hides all top level items except the expanded one : it crashes.
Example of code :
QWidget* l_widget = new QWidget();
QTreeWidget* l_treeWidget = new QTreeWidget(l_widget);
l_treeWidget->addTopLevelItem(new QTreeWidgetItem(QStringList("item1")));
l_treeWidget->addTopLevelItem(new QTreeWidgetItem(QStringList("item2")));
l_treeWidget->topLevelItem(1)->addChild(new QTreeWidgetItem(QStringList("child1")));
l_treeWidget->setAnimated(true);
QObject::connect(l_treeWidget, &QTreeWidget::itemExpanded, [=](QTreeWidgetItem* p_item) {
for (int j = 0; j < l_treeWidget->topLevelItemCount(); ++j)
if (l_treeWidget->topLevelItem(j) != p_item)
l_treeWidget->topLevelItem(j)->setHidden(true);
});
l_widget->show();
