Description
when implicitWidth of TreeViewDelegate changes, TreeView will not update automatically.
for example, modify the viewDelegate in the tableofcontents example:
viewDelegate:
onImplicitWidthChanged: {
console.log("implicitWidthChanged")
}
contentItem: Label {
id: label
x: viewDelegate._padding + (viewDelegate.depth + 1 * viewDelegate.indentation)
width: parent.width - viewDelegate._padding - x
property bool flag: false
TapHandler {
onTapped: {
console.log("tapped")
label.flag = !label.flag
}
}
text: viewDelegate.model.display + (flag ? "extra text" : "")
elide: Text.ElideRight
}
when tapping on the text, "extra text" will be added and "implicitWidthChanged" will be emitted. However the TreeView needs extra signals to resize, for example toggleExpanded
