In Qt Creator, examples are missed

Question

Installed Qt Creator 2.8 in ArchLinux Installed qt5-* (* as every related package) using pacman

examples were not available in the repositories so I used the one in the AUR, qt5-examples

examples are installed under /usr/share/doc/qt/examples

qmake-qt5 -query says:

QMAKE_VERSION:3.0
QT_VERSION:5.1.0

which means examples are in the right place

But they are not shown in Qt Creator!

How can I bring them in qtcreator?

PS: I don't wanna forget about the solution and install SDK.

Answer 1

I know OP asked for archlinux but I faced the same issue with Ubuntu 20.04. To solve it I had to install the following two packages:

sudo apt-get install qtbase5-examples qtbase5-doc-html

This will show the basic widget examples.

Additional examples (e.g. qt quick) can be added by installing them explicitly:

sudo apt install qtquickcontrols2-5-examples

To actually get them displayed in qtcreator I had to install:

sudo apt install qt5-doc qt5-doc-html

Here is the output of echo $(apt-mark showmanual | grep -P '(libqt|qt)')

cmake-qt-gui qt5-default qt5-doc qt5-doc-html qtbase5-dev qtbase5-doc-html qtbase5-examples qtcreator qtquickcontrols2-5-examples

Edit:

Also make sure to install the qml modules you need, for example:

sudo apt install qml-module-qtquick-controls2

Answer 2

Qtcreator cannot detect the example without its html file.

So, in my case I've already installed qtbase5-examples, but could not able to see examples in qtcreator.

After,

sudo apt-get install qtbase5-doc-html

examples are visible in qtcreator. It was the same with qt5serialport-examples.

sudo apt-get install qt5serialport-examples qtserialport5-doc-html

Have a nice one.

Answer 3

My situation is that qt example folder has no permission to read and execute for non-root users, fixed it and everything OK. In your case:

sudo chmod +rx /usr/share/doc/qt/examples
