Description
When I create tab view using components from QtQuick.Controls 2 with tabs created from model an content for this tabs has Window, program crashes on deleting items from model.
If I remove Window or remove TabBar - no crashes.
To reproduce, run the following example and press "Delete" button.
import QtQuick 2.0 import Qt.labs.controls 1.0 import QtQuick.Layouts 1.3 ApplicationWindow { visible: true width: 640 height: 480 ListModel { id: tabModel ListElement { text: "Test 0" source: "TestItem.qml" } ListElement { text: "Test 1" source: "TestItem.qml" } } ColumnLayout { anchors.fill: parent TabBar { id: tabBar Layout.fillHeight: false Layout.fillWidth: true currentIndex: 1 Repeater { model: tabModel delegate: TabButton { text: model.text } } } StackLayout { id: stackLayout Layout.fillHeight: true Layout.fillWidth: true currentIndex: tabBar.currentIndex Repeater { model: tabModel delegate: Loader { source: model.source } } } Button { Layout.alignment: Qt.AlignHCenter text: "Delete" onClicked: tabModel.remove(0) } } }
import QtQuick 2.0 import QtQuick.Window 2.0 Item { Window { } Text { anchors.centerIn: parent text: "Item %1".arg(model.index) } }
