[Guide] Code completion on Qt Creator for Ubuntu.Components

doniks

mhm, so while this works now to resolve import Ubuntu.Components 1.3 in a .qml file, but it still does not find #include <QtQml> or #include <QDebug> in a .cpp file. any idea?

lduboeuf

@doniks are you working with a clickable template? I guess QtCreator does not find Qt libs, you should check in settings Qt paths

doniks

@lduboeuf yes. the whatsitcalled qml with c++ plugin template

lduboeuf

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

you can see if any issue with paths in kits

Video showing the WIP of having qtcreator running above clickable image :

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

@lduboeuf

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

lduboeuf

@Abuabdellah i don't know if Ubuntu.Components are installable on 19.10 but you can wait for the clickable ide qtcreator feature or try the 1st post Guide solutions

Abuabdellah

thank you @lduboeuf

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

lduboeuf

@Abuabdellah Well html5 components is peobably elsewhere, here you are looking to qt qml one

lduboeuf

@Abuabdellah look here /usr/share/ubuntu-html5...
dpkg -L ubuntu-html5-ui-toolkit

Abuabdellah

thank you @lduboeuf

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

lduboeuf

@doniks well it seems there is definitly an issue with Qt5 path. probably you may found resources around about that

@lduboeuf

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?

lduboeuf

@Talkless You can use whatever QtCreator version, the only limit is to use the right Qt Version ( 5.9.5 currently and soon 5.12 )

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.
