Have you checked also theclickable ide qtcreator feature ?

Yes, it did the trick! Very convenient.
EDIT: well, OK, it would be much more convenient if that qtcreator had "clickable" integration to avoid terminal, but that's not that bad.

Have you checked also theclickable ide qtcreator feature ?

Just to share my experience for developping Apps with QtCreator:

Should I use QtCreator from 16.04, ubuntu-sdk or can I use latest QtCreator form Qt online installer?

have you installed locally QtQuickControl 2 ?
sudo apt install qtquickcontrols2-5-dev

you can see if any issue with paths in kits

Taking a new stab at this ... So, again resolving Ubuntu.Components in qml files works fine, but resolving Qt includes in cpp files does not. I have qtquickcontrols2-5-dev installed and I don't see anything screaming at me in the Kits section ... but maybe it's still wrong?! See attached. Qt version = None might be wrong?! But I can't select anything else.

Update: In Kits -> Qt Versions there is nothing there. I guess that is the problem, but I can't figure out how to get anything in there ... I found some reports online that sudo apt install qt5-default might help, but it doesn't help me

Update2: Now I manually added /usr/lib/x86_64-linux-gnu/qt5/bin/qmake in Qt Versions, and selected that in the Kit, closed and reopened, but still doesn't find any QtStuff

I didn't see html5 components on the image! isn't there or it is included in other image?

root@ea8e2a8bedfb:/# ls usr/lib/x86_64-linux-gnu/qt5/
bin  libexec  mkspecs  plugins  qml  qt.conf

is there a wiki to get code completion on ubuntu 19.10?

full code completion for all UT components and qml modules , and can launch directly the app, you can debug the c++ part also.
The demo covers python and c++ clickable template, and address-book-app

• A more generic solution using clickable image:

I'm trying this approach. The path variable should include the qml dir

cd ~/docs/devel
mkdir qml-module-ubuntu-components
cd qml-module-ubuntu-components/
docker cp silly_bose:/usr/lib/x86_64-linux-gnu/qt5/qml .
export QML_IMPORT_PATH=~/docs/devel/qml-module-ubuntu-components/ 
qtcreator # -> doesn't work
export QML_IMPORT_PATH=~/docs/devel/qml-module-ubuntu-components/qml
qtcreator # -> this works

So, you should set the variable such that you find this one:

ls -dl $QML_IMPORT_PATH/Ubuntu

What OS are you working on ?.
Is your clickable up to date ?

Most likely, the application was supposed to call dbus_connection_close(), since this is a private connection.

Is it possible to get Ubuntu.Components recognized by QtCreator on Windows?

The copy components from docker solution should work ?
