Can find TreeView module in QML

[ocgltd]

I'm trying to build a simple QML app which uses a TreeView, using QT Creator with QT 5.15.2. I discovered that TreeView is not included with QtQuick Controls 2.x so the compilation fails.

Instead it seems (if I understand the documentation correctly) that I must import QtQuick.Controls 1.4 But Qt Creator complains that it's not installed. And the Qt Maintenance tools doesn't offer a way to install this.

Help! What am I doing wrong?

I installed 5.x kit, so Qt Controls 1.x SHOULD be installed. I closed Qt Creator and reopened and now warning is gone. Strange...

But I am still unclear on something. is TreeView included with QtQuick Controls 2.x ? If not, does that mean TreeView is deprecated and will be dropped in Qt 6? (Should I avoid using TreeView ?)

@ocgltd if you're running open source, you can get it "for free" from the market place

QtQuick.Controls 1.x is always installed. Did you try using it with QtQuick.Controls 2.x?
Is that case:

import QtQuick.Controls 1.4 as QC1

...

QC1.TreeView {
}

@fcarney if the op uses Qt6, than Control 1 is not automatically installed :(

I know @ocgltd said using QT Creator with QT 5.15.2 but that may be from the about QtCreator page and not from the kit he uses
