Examples don't show up

[jsulm]

@gabrield-droid See https://wiki.qt.io/Qt_Examples_in_Qt_Creator
What does

qmake -query QT_INSTALL_DOCS

return? Make sure you use qmake from your custom Qt build.

[gabrield-droid]

@jsulm It returns /opt/Qt6/doc. What does it mean?

[cristian-adam]

@gabrield-droid The Examples part is usually configured by the Qt SDK.

I have for example in my /Users/cristian/Qt/Tools/sdktool/QtProject/QtCreator.ini the following bits:

[Help]
InstalledDocumentation=/Users/cristian/Qt/Docs/Qt-6.10.0/
InstalledExamples=Qt 6.10.0|/Users/cristian/Qt/Docs/Qt-6.10.0|/Users/cristian/Qt/Examples/Qt-6.10.0/       

Add these settings to your QtCreator.ini and you should get the Examples working.

@cristian-adam How did you install Qt? Did you install it like I show in the question? I searched for QtCreator.ini in my device and I got four files named QtCreator.ini, all are in QtCreator source directory which I haven't built yet.

[jsulm]

@gabrield-droid said in Examples don't show up:

QtCreator.ini

This is the QtCreator config file. Should be: ~/.config/QtProject/QtCreator.ini

[cristian-adam]

@gabrield-droid I used the Qt SDK. But, after one Qt Creator run, you should have a QtCreator.ini file in ~/.config/QtProject on Linux.

See https://doc.qt.io/qtcreator/creator-how-to-find-settings-files.html for more information.

[gabrield-droid]

@cristian-adam I found it. What should I do now?

[jsulm]

@gabrield-droid See https://forum.qt.io/post/834437

This post is deleted!

[gabrield-droid]

@jsulm
Only does the version appear, not the projects

I have added these lines in the [Help] in the QtCreator.ini:

InstalledDocumentation=/opt/Qt6/doc
InstalledExamples=Qt 6.10.1|/opt/Qt6/doc|/opt/Qt6/examples

Is there more something wrong?

[cristian-adam]

@gabrield-droid You could try running Qt Creator as:

$ QT_LOGGING_RULES=qtc.examples=true ./qtcreator

See the code loading the examples at https://github.com/qt-creator/qt-creator/blob/18.0/src/plugins/qtsupport/exampleslistmodel.cpp#L67

[gabrield-droid]

@cristian-adam I still don't see the examples. But, in the terminal, it returns something like this:

qtc.examples: Reading Help/InstalledExamples from settings: QList("Qt 6.10.1|/opt/Qt6/doc|/opt/Qt6/examples")
qtc.examples: Adding examples set displayName= "Qt 6.10.1" , manifestPath= "/opt/Qt6/doc" , examplesPath= "/opt/Qt6/examples"
qtc.examples: Skipping "Qt 6.10.1 (Qt6)" because it either is remote, or its QT_INSTALL_EXAMPLES and QT_INSTALL_DEMOS, or QT_INSTALL_DOCS paths are not readable directories, or there are no documentation files.

Maybe, you could help with that

[jsulm]

@gabrield-droid Check the content of /opt/Qt6/doc and /opt/Qt6/examples - is there something inside? Doe you have read access there?

[gabrield-droid]

@jsulm In /opt/Qt6/doc/ there are two folders called config and global. The contents of /opt/Qt6/examples are shown in the picture below:

Both folders are owned by root and have their permissions set to rwxr-xr-x

Hi, I've solved this problem. In README.md, I found an extra step to install the documentation. I should've run these commands after installing Qt:

cmake --build . --target docs

sudo cmake --build . --target install_docs

But, since I had deleted my qt-build and /opt/Qt6/examples, I did these following to make the examples, along with the documentation, accessible from within Qt Creator:

mkdir qt-build && cd qt-build

~/qt-sources/configure -prefix /opt/Qt6 -skip qtwebengine -nomake tests -make examples -- -DQT_BUILD_EXAMPLES_BY_
DEFAULT=OFF -DQT_INSTALL_EXAMPLES_SOURCES=ON 

cmake --build . --parallel --target docs

sudo cmake --install . --component examples_sources 

sudo cmake --build . --parallel --target install_docs

After that, the examples and documentation are accessible from Qt Creator:
