I have installed the latest Qt 5.5.0, but there seems to be only QtQuick.Controls 1.0 and 1.1. I want to use TreeView, which is contained in the 1.4 version.

Thanks. Found on 3 different directories ~/Qt5.5.0/5.5/Src/qtquickcontrols/src/controls/TreeView.qml--- ~/Qt5.5.0/5.5/gcc_64/qml/QtQuick/Controls/TreeView.qml--- ~/Qt5.5.0/Tools/QtCreator/bin/qml/QtQuick/Controls/TreeView.qml Which one should I add to the path? @VictorPolevoy – Zen
Wait... did you actually try to run an example that uses the 1.4 version of the controls? – Mitch
Dude, there are so many examples, how do you know which one uses the 1.4 version. Whatever, I found one. Though qt creator keeps warning TreeView component is not found, it works. Thanks @Mitch – Zen

You should already have it. Try to find the TreeView.qml by using locate TreeView.qml. Also, QtCreator or your IDE should have proper QML_IMPORT_PATH which is taken from environment. For example, my QtCreator does not have set proper paths so I use it with shell script which sets the path and runs /usr/bin/qtcreator after - this makes QtCreator to see new QML modules. I don't know is this a bug or just a ubuntu-package problem, but it worked for me only when I set the QML_IMPORT_PATH manually.

You say you have these paths:

~/Qt5.5.0/5.5/Src/qtquickcontrols/src/controls/TreeView.qml

~/Qt5.5.0/5.5/gcc_64/qml/QtQuick/Controls/TreeView.qml

~/Qt5.5.0/Tools/QtCreator/bin/qml/QtQuick/Controls/TreeView.qml

Looks like you installed it by downloading official installer from Qt's site. So, the first path is a sources path. Don't use it ever, it is only needed to be installed into correct directory after compiling Qt from sources and performing make install.

The third one is integrated with your QtCreator installation, but it seems it does not work for you.

I'd say, your choice is to use second path (~/Qt5.5.0/5.5/gcc_64/qml/QtQuick/Controls/TreeView.qml). It is usually installed automatically to /usr/lib/x86_64-linux-gnu/qt5/ on amd64 architecture and to /usr/lib/i386-linux-gnu/ for i386 architecture.

So, create a script in /usr/bin/, call it dev-qtcr for example and put inside it:

#!/bin/bash

export QML_IMPORT_PATH=/home/user/Qt5.5.0/5.5/gcc_64/qml
qtcreator

Be sure to change /home/user to your home directory.

Did you tried to export QML2_IMPORT_PATH rather than QML_IMPORT_PATH ?

An other solution, which is quite ugly, is to edit the qmldir file from gcc/qml/QtQuick/Controls and add the following line:

TreeView 1.4 TreeView.qml

As a result for me :

module QtQuick.Controls
plugin qtquickcontrolsplugin
classname QtQuickControlsPlugin
typeinfo plugins.qmltypes
designersupported
depends QtQuick.Window 2.2 
TreeView 1.4 TreeView.qml

You can do so for each QML file which is in the QtQuick/Controls directory.

In this way, TreeView and all other QML types you will add to this file will be recognized by QtCreator.
