    \title How To

    The following topics describe how to use \QC to perform a particular task.

    \section1 Analyze

    Use integrated code analysis tools to detect memory leaks, profile
    function execution, analyze CPU use, and eliminate unnecessary
    complexity of code. Other integrated tools provide code coverage and
    visualize trace events.

    \generatelist creator-how-to-analyze

    \section1 Build and Run

    Use integrated cross-platform systems for build automation to compile your
    source code for different target platforms or with different compilers,
    debuggers, or Qt versions. Deploy applications to the target platforms
    and run them there.

    \generatelist creator-how-to-build

    \section2 Build with CMake

    CMake controls the software compilation process by using simple configuration
    files, called \e CMakeLists.txt files.

    \generatelist creator-how-to-build-with-cmake

    \section2 Build with qmake

    qmake automates the generation of Makefiles based on the information in a
    project file that has the extension \e .pro.

    \generatelist creator-how-to-build-with-qmake

    \section2 Run applications

    Run applications on local and remote desktop systems, as well as on
    embedded and mobile devices that you connect to the computer.

    \generatelist creator-how-to-run

    \section1 Create Models and Diagrams

    Create Universal Modeling Language (UML) style models with structured and
    behavioral diagrams that offer different views to your system. Or, use a
    file wizard to create State Chart XML (SCXML) files with boilerplate code
    and edit them with an SCXML editor.

    \generatelist creator-how-to-models

    \section1 Debug

    Use debuggers to inspect the state of your application while it is running.

    \generatelist creator-how-to-debug

    \section1 Design UIs

    Design UIs with either \l{User Interfaces}{Qt Quick or Qt Widgets}.
    \QC integrates a visual editor, \QD, for designing widget-based UIs
    in the \uicontrol Design mode. For Qt Quick UIs, use a separate visual
    editor, \l{\QDS Manual}{\QDS}, or the \uicontrol Edit mode.

    \generatelist creator-how-to-design

    \section1 Develop for Devices

    Install the toolchain for building applications for the targeted
    embedded or mobile platform on the computer, and use \QOI to
    install Qt libraries that are built for the platform. Then add a
    kit with the toolchain and the Qt version for the device's architecture.
    When possible, \QOI creates suitable kits for you. Connect the devices
    to the computer to run, debug, and analyze applications on them.

    \section2 Android

    Install \l {Qt for Android} and Android tools, and connect Android devices to
    the computer.

    \generatelist creator-how-to-android

    \section2 Bare Metal

    Run and debug applications on small Linux devices that are not supported
    by the remote Linux device plugin by using GDB or a hardware debugger.

    \generatelist creator-how-to-bare-metal

    \section2 \B2Q

    Run, debug, and analyze applications on \l{\B2Q: Documentation}{\B2Q}
    devices.

    \generatelist creator-how-to-b2qt

    \section2 Docker

    Create \e {Docker devices} from \e {Docker images} and use them to build,
    run, and debug applications.

    \generatelist creator-how-to-docker

    \section2 iOS

    Install \l {Qt for iOS} and Xcode, and connect iOS devices to the computer.

    \generatelist creator-how-to-ios

    \section2 MCUs

    Install \l {Qt for MCUs}, and connect microcontrollers to the computer.

    \generatelist creator-how-to-mcu

    \section2 QNX Neutrino

    \section2 Remote Linux

    Add kits for toolchains for building applications for generic Linux
    devices, and connect the devices to the computer.

    \generatelist creator-how-to-remote-linux

    \section2 SDKs

    Manage SDKs for application development for different platforms.

    \generatelist creator-how-to-sdks

    \section2 VxWorks

    Build \l {Qt for VxWorks}, and create VxWorks build and run kits.

    \generatelist creator-how-to-vxworks

    \section2 WebAssembly

    Install \l{Qt for WebAssembly} to build applications for the web and run them
    in a web browser.

    \generatelist creator-how-to-webassembly

    \section1 Edit Code

    The code editor offers useful features for editing C++ and QML code, such
    as semantic highlighting, checking code syntax, code completion, and quick
    fixes. Some of these features are also for other programming languages, such
    as Python, for which a \e {language server} is available that provides
    information about the code to IDEs.

    \generatelist creator-how-to-edit

    \section2 Configure Editors

    Configure the code and text editor to suit your specific needs by
    changing the fonts, colors, highlighting, and indentation.

    \generatelist creator-how-to-configure-editors

    \section2 Manage Language Servers

    Configure language servers that \QC adds by default or add more of them.

    \generatelist creator-how-to-lsp

    \section2 Search

    Use the incremental and advanced search to search in currently open projects
    or files on the file system or use the locator to browse through projects,
    files, classes, functions, documentation, and file systems.

    \generatelist creator-how-to-search

    \section1 Manage Kits

    \QC groups build and run specific settings as kits to make cross-platform
    development easier. Each kit consists of a set of values that define one
    environment, such as a device, toolchain, Qt version, and debugger command
    to use.

    \generatelist creator-how-to-manage-kits

    \section1 Manage Projects

    Create projects for developing applications and libraries. Then configure
    the projects for building and running the applications on target platforms.

    \generatelist creator-how-to-projects

    \section2 Create Projects

    Use preset wizards to create projects or add custom wizards. You can also
    import projects from version control systems.

    \generatelist creator-how-to-projects-create

    \section2 Add Files

    Add files to projects.

    \generatelist creator-how-to-projects-files

    \section2 Configure Projects

    Change the default configurations that installation programs and project
    wizards create.

    \generatelist creator-how-to-projects-configure

    \section1 Read Documentation

    \QC integrates the reference documentation for the Qt versions that you
    install. You can add documentation from other sources.

    \generatelist creator-how-to-get-help

    \section1 Test

    Create and run \e {code based tests} and \e {build system based tests}.
    Code based testing offers special handling for particular testing
    frameworks that strongly ties to the underlying code models or
    specialized parsers. Build system based testing is independent from any
    testing frameworks. It retrieves information directly from the underlying
    build system and uses it or even the build system as such to execute the
    respective tests.

    \generatelist creator-how-to-test

    \section1 Use Git

    \l{Git} is a fast decentralized version control system
    that is available for Windows, Linux, and \macos. You can use the
    \l {Gerrit Code Review} tool for projects that use Git.

    \generatelist creator-how-to-git

    \section2 Current file

    \generatelist creator-how-to-git-current-file

    \title Run \QC from the command line

    You can start \QC and specify some options from the command line. For
    example, you can open a file to any line and column.

    To use command-line options, enter the following command in the
    directory that contains the \QC executable or specify the path to
    \QC as a part of the command:

    \badcode
    qtcreator [option] [filename[:line_number[:column_number]]]
    \endcode

    \note You can use either a colon (:) or a plus sign (+) as a separator
    between the filename and line number and the line number and the column
    number. You can also use a space between the separator and the line number.

    \section1 Examples of CLI commands

    The following are examples of the commands on supported platforms when you
    install \QC with \l{Get and Install Qt}{\QOI} to the default location. Change
    the paths as necessary.

    On Windows:

    \list

        \li \c {C:\Qt\Tools\QtCreator\bin\qtcreator -help}

        \li \c {C:\Qt\Tools\QtCreator\bin\qtcreator C:\TextFinder\textfinder.cpp:100:2}

        \li \c {C:\Qt\Tools\QtCreator\bin\qtcreator C:\TextFinder\textfinder.cpp +100+2}

    \endlist

    On Linux:

    \list

        \li \c {~/Qt/Tools/QtCreator/bin/qtcreator -help}

        \li \c {~/Qt/Tools/QtCreator/bin/qtcreator /src/TextFinder/textfinder.cpp:100:2}

        \li \c {~/Qt/Tools/QtCreator/bin/qtcreator /src/TextFinder/textfinder.cpp+100+2}

    \endlist

    On \macos:

    \list

        \li \c {~/Qt/Qt\ Creator.app/Contents/MacOS/Qt\ Creator -help}

    \endlist

    \section1 Open a project from a directory

    To open a project that is located in a particular directory, you can
    pass on the directory name as a command-line argument. \QC looks for
    a \l{Manage sessions}{session} that matches the directory name and
    loads it. Or it looks for a project file in the directory and opens it.

    For example, on Windows:

    \c {C:\qtcreator\bin>qtcreator.exe C:\Examples\alarms}

    \sa {Command-Line Options}
