    @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.

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

      Why do my Qt exxamples not show up like in the picture? Are there any configurations I didn't set when run [qt-sources]/configure? Or is the problem in the Qt Creator itself? Or, should I build the Qt Creator from source as well?

      This is how I installed Qt frameworks and Qt Creator

      • Qt v6.10.1
        • I ran mkdir qt_sources, and then cd qt_sources
        • Within ~/qt_sources, I ran git clone --branch v6.10.1 git://code.qt.io/qt/qt5.git .
        • I created directory ~/qt-build
        • Within ~/qt-build, I ran ~/qt-sources/configure -init-submodules, then ~/qt-sources/configure -skip qtwebengine -prefix /opt/Qt6 -make examples -install-examples-sources
        • After configuring, I ran cmake --build . --parallel.
        • And then, sudo cmake --install .
      • Qt Creator
        • I downloaded the .deb installed from https://download.qt.io/official_releases/qtcreator/18.0/18.0.0/cpack_experimental/qtcreator-opensource-linux-x86_64-18.0.0.deb and installed Qt Creator using this file

      Other information that might be useful

      @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.

          QtCreator.ini

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

            @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.

                    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?

                      @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

                        @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")

                        Maybe, you could help with that

                            @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:

                              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:
