    \title Opening Projects

    \QC stores information that it needs to build projects in a .user file. If
    \QC cannot find the file when you open an existing project, it prompts you
    to enter the information. If you used another \QC instance to create the
    project, \QC asks whether you want to use the old settings. The settings
    are specific to the development environment, and you should not copy them from
    one environment to another. Therefore, we recommend that you select \uicontrol No
    and enter the information again in the \uicontrol {Configure Project} tab.

    The \uicontrol {Configure Project} tab displays a list of \l{glossary-buildandrun-kit}{kits}
    for building and running projects, that you install on the development PC and
    configure in \uicontrol Edit > \uicontrol Preferences > \uicontrol Kits.
    Select the kits that you want to build and run the project with.

    Even if you do not intend to build the project, the C++ and QML code models
    need a Qt version and compiler to offer code completion. To specify them,
    select the \uicontrol Preferences link, or select \uicontrol Edit >
    \uicontrol Preferences > \uicontrol Kits.

    Qt for Python projects rely on the \l{Using Language Servers}
    {language server client} for code completion, highlighting, and
    other useful features.

    If \QC cannot find an existing build for a particular \l{glossary-buildandrun-kit}{kit},
    it starts out
    from a clean slate, and creates new debug and release build configurations
    in the specified directory. \QC suggests a name
    and location for the directory that you can change.

    If you have built the project before, \QC can use the existing build
    configuration to make the exact same build available to you. To import a
    build, specify a directory in the
    \uicontrol {Import Build From} section and select \uicontrol {Import}.

    You can edit the build configuration later. For more information, see
    \l{Editing Build Configurations}.

    To open a project:

    \list 1

        \li Select \uicontrol File > \uicontrol {Open File or Project}
            (\key Ctrl+O or \key Cmd+O on \macos) and select the project file
            for the project to open: \e {.pro} (qmake), \e {CMakeLists.txt}
            (CMake), \e {.qbs} (Qbs), \e {meson.build} (Meson), \e {pyproject} (Python), or
            \e {Makefile.am} (Autotools, experimental).

        \li In the \uicontrol {Configure Project} tab, select kits for building
            and running your project.

        \li Select \uicontrol {Configure Project}.

    \endlist

    You can use the following keyboard shortcuts to open projects, depending on
    the mode you are currently in:

    \list

        \li In all modes, press \key Ctrl+O (\key Cmd+O on \macos) to open the
            \uicontrol {Open File} dialog, where you can select a project file
            to open a project.

        \li In all modes, except the \uicontrol Help mode, press
            \key Ctrl+Shift+O (\key Cmd+Shift+O on \macos) to open the
            \uicontrol {Load Project} dialog, where you can select a project
            file to open a project.

        \li In the \uicontrol Welcome mode, \uicontrol Projects tab, press
            \key Ctrl+Shift+number (\key Cmd+Shift+number on \macos), where
            the number is the number of a project in the list of recently opened
            projects.

    \endlist

    \QC parses all the source files in the project and performs a semantic
    analysis to build up the information that it needs for functions such as
    navigation and finding usages. A progress bar is displayed during parsing.
    To show or hide detailed progress information, select
    \uicontrol {Toggle Progress Details} (1).
