Description
When dynamically creating TableViewColumn elements using an Instantiator, the application crashes on iOS and Android.
Run the following qml file on an iOS or Android device:
import QtQuick 2.4
import QtQuick.Controls 1.3
Item {
id: root
readonly property var datasets: [
{0: "Test", 1: "Another", 2: "Column"},
{0: "Test", 1: "Another", 2: "Column"},
{0: "Test", 1: "Another", 2: "Column"},
{0: "Test", 1: "Another", 2: "Column"},
{0: "Test", 1: "Another", 2: "Column"}
]
TableView {
id: table
anchors.fill: parent
Instantiator {
model: Object.keys(root.datasets[0]).length
delegate: TableViewColumn {
role: index
title: "Column " + (index + 1)
}
onObjectAdded: table.addColumn(object)
onObjectRemoved: table.removeColumn(index)
}
model: root.datasets
}
}
If you remove the onObjectAdded: table.addColumn(object) line, the table is empty, of course, but no longer crashes. Also creating TableViewColumn items outside and adding them in, say, Component.onCompleted works fine. It's just through the Instantiator that it crashes, it runs fine on a Linux desktop machine.
