Qt Creator

Qt Creator is a cross-platform, integrated development environment (IDE) for
application developers to create applications for multiple desktop, embedded,
and mobile device platforms.

The Qt Creator Manual is available at:

https://doc.qt.io/qtcreator/index.html

For an overview of the Qt Creator IDE, see:

https://doc.qt.io/qtcreator/creator-overview.html

Supported Platforms

The standalone binary packages support the following platforms:

Windows 10 (64-bit) or later
(K)Ubuntu Linux 20.04 (64-bit) or later
macOS 10.14 or later

Contributing

For instructions on how to set up the Qt Creator repository to contribute
patches back to Qt Creator, please check:

https://wiki.qt.io/Setting_up_Gerrit

See the following page for information about our coding standard:

https://doc.qt.io/qtcreator-extending/coding-style.html

Compiling Qt Creator

Prerequisites:

Qt 6.2 or later. The Qt version that you use to build Qt Creator defines the
minimum platform versions that the result supports
(Windows 10, RHEL/CentOS 8.4, Ubuntu 20.04, macOS 10.14 for Qt 6.2).
Qt WebEngine module for QtWebEngine based help viewer
On Windows:
- MinGW with GCC 9 or Visual Studio 2019 or later
- Python 3.5 or later (optional, needed for the python enabled debug helper)
- Debugging Tools for Windows (optional, for MSVC debugging support with CDB)
On Mac OS X: latest Xcode
On Linux: GCC 9 or later
LLVM/Clang 10 or later (optional, LLVM/Clang 14 is recommended.
See instructions on how to
get LLVM.
The ClangFormat plugin uses the LLVM C++ API.
Since the LLVM C++ API provides no compatibility guarantee,
if later versions don’t compile we don’t support that version.)
CMake
Ninja (recommended)

The used toolchain has to be compatible with the one Qt was compiled with.

Linux and macOS

These instructions assume that Ninja is installed and in the PATH, Qt Creator
sources are located at /path/to/qtcreator_sources, Qt is installed in
/path/to/Qt, and LLVM is installed in /path/to/llvm.

Note that if you install Qt via the online installer, the path to Qt must
include the version number and compiler ABI. The path to the online installer
content is not enough.

Note that /path/to/Qt doesn’t imply the full path depth like:
$USER/Qt/6.2.4/gcc_64/lib/cmake/Qt6, but only $USER/Qt/6.2.4/gcc_64.

See instructions on how to
get LLVM.

mkdir qtcreator_build
cd qtcreator_build

cmake -DCMAKE_BUILD_TYPE=Debug -G Ninja "-DCMAKE_PREFIX_PATH=/path/to/Qt;/path/to/llvm" /path/to/qtcreator_sources
cmake --build .

Windows

These instructions assume that Ninja is installed and in the PATH, Qt Creator
sources are located at pathtoqtcreator_sources, Qt is installed in
pathtoQt, and LLVM is installed in pathtollvm.

Note that if you install Qt via the online installer, the path to Qt must
include the version number and compiler ABI. The path to the online installer
content is not enough.

Note that pathtoQt doesn’t imply the full path depth like:
c:Qt6.2.4msvc2019_64libcmakeQt6, but only c:/Qt/6.2.4/msvc2019_64.
The usage of slashes / is intentional, since CMake has issues with backslashes
in CMAKE_PREFX_PATH, they are interpreted as escape codes.

See instructions on how to
get LLVM.

Decide which compiler to use: MinGW or Microsoft Visual Studio.

MinGW is available via the Qt online installer, for other options see
https://wiki.qt.io/MinGW. Run the commands below in a shell prompt that has
<path_to_mingw>bin in the PATH.

For Microsoft Visual C++ you can use the «Build Tools for Visual Studio». Also
install the «Debugging Tools for Windows» from the Windows SDK installer. We
strongly recommend using the 64-bit version and 64-bit compilers on 64-bit
systems. Open the x64 Native Tools Command Prompt for VS <version> from the
start menu items that were created for Visual Studio, and run the commands
below in it.

md qtcreator_build
cd qtcreator_build

cmake -DCMAKE_BUILD_TYPE=Debug -G Ninja "-DCMAKE_PREFIX_PATH=/path/to/Qt;/path/to/llvm" pathtoqtcreator_sources
cmake --build .

Qt Creator can be registered as a post-mortem debugger. This can be done in the
options page or by running the tool qtcdebugger with administrative privileges
passing the command line options -register/unregister, respectively.
Alternatively, the required registry entries

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionAeDebug
HKEY_LOCAL_MACHINESOFTWAREWow6432NodeMicrosoftWindows NTCurrentVersionAeDebug

can be modified using the registry editor regedt32 to contain

qtcreator_buildbinqtcdebugger %ld %ld

When using a self-built version of Qt Creator as post-mortem debugger, it needs
to be able to find all dependent Qt-libraries and plugins when being launched
by the system. The easiest way to do this is to create a self-contained Qt
Creator by installing it and installing its dependencies. See «Options» below
for details.

Note that unlike on Unix, you cannot overwrite executables that are running.
Thus, if you want to work on Qt Creator using Qt Creator, you need a separate
installation of it. We recommend using a separate, release-built version of Qt
Creator to work on a debug-built version of Qt Creator.

Options

If you do not have Ninja installed and in the PATH, remove -G Ninja from
the first cmake call. If you want to build in release mode, change the build
type to -DCMAKE_BUILD_TYPE=Release. You can also build with release
optimizations but debug information with -DCMAKE_BUILD_TYPE=RelWithDebInfo.

You can find more options in the generated CMakeCache.txt file. For instance,
building of Qbs together with Qt Creator can be enabled with -DBUILD_QBS=ON.

Installation is not needed. It is however possible, using

cmake --install . --prefix /path/to/qtcreator_install

To create a self-contained Qt Creator installation, including all dependencies
like Qt and LLVM, additionally run

cmake --install . --prefix /path/to/qtcreator_install --component Dependencies

Perf Profiler Support

Support for the perf profiler
requires the perfparser tool that is part of the Qt Creator source package, and also
part of the Qt Creator Git repository in form of a submodule in src/tools/perfparser.

Compilation of perfparser requires ELF and DWARF development packages.
You can either download and extract a prebuilt package from
https://download.qt.io/development_releases/prebuilt/elfutils/ and add the
directory to the CMAKE_PREFIX_PATH when configuring Qt Creator,
or install the libdw-dev package on Debian-style Linux systems.

You can also point Qt Creator to a separate installation of perfparser by
setting the PERFPROFILER_PARSER_FILEPATH environment variable to the full
path to the executable.

Getting LLVM/Clang for the Clang Code Model

The Clang code model uses Clangd and the ClangFormat plugin depends on the
LLVM/Clang libraries. The currently recommended LLVM/Clang version is 14.0.

Prebuilt LLVM/Clang packages

Prebuilt packages of LLVM/Clang can be downloaded from
https://download.qt.io/development_releases/prebuilt/libclang/

This should be your preferred option because you will use the version that is
shipped together with Qt Creator (with backported/additional patches). In
addition, MinGW packages for Windows are faster due to profile-guided
optimization. If the prebuilt packages do not match your configuration, you
need to build LLVM/Clang manually.

If you use the MSVC compiler to build Qt Creator the suggested way is:
1. Download both MSVC and MinGW packages of libclang.
2. Use the MSVC version of libclang during the Qt Creator build.
3. Prepend PATH variable used for the run time with the location of MinGW version of libclang.dll.
4. Launch Qt Creator.

Building LLVM/Clang manually

You need to install CMake in order to build LLVM/Clang.

Build LLVM/Clang by roughly following the instructions at
http://llvm.org/docs/GettingStarted.html#git-mirror:

Clone LLVM/Clang and checkout a suitable branch

git clone -b release_130-based --recursive https://code.qt.io/clang/llvm-project.git

Build and install LLVM/Clang

For Linux/macOS:

cmake 
  -D CMAKE_BUILD_TYPE=Release 
  -D LLVM_ENABLE_RTTI=ON 
  -D LLVM_ENABLE_PROJECTS="clang;clang-tools-extra" 
  -D CMAKE_INSTALL_PREFIX=<installation location> 
  ../llvm-project/llvm
cmake --build . --target install

For Windows:

cmake ^
  -G Ninja ^
  -D CMAKE_BUILD_TYPE=Release ^
  -D LLVM_ENABLE_RTTI=ON ^
  -D LLVM_ENABLE_PROJECTS="clang;clang-tools-extra" ^
  -D CMAKE_INSTALL_PREFIX=<installation location> ^
  ..llvm-projectllvm
cmake --build . --target install

Clang-Format

The ClangFormat plugin depends on the additional patch

https://code.qt.io/cgit/clang/llvm-project.git/commit/?h=release_130-based&id=42879d1f355fde391ef46b96a659afeb4ad7814a

While the plugin builds without it, it might not be fully functional.

Note that the plugin is disabled by default.

В этой статье мы разберём как установить Qt на Windows 7 и выше, плоть до Windows 10, думаю вам будет полезно и интересно.

Также если вы планируете в будущем перейти на Linux, то для установки Qt на него, прочитайте статью «Как установить Qt 5 на Linux Ubuntu».

Как установить Qt на Windows:

Чтобы вам установить Qt, вам сначала нужно скачать установщик, сделать это можно с официального сайта, переходим на него.

Там сверху вы увидите кнопку с надписью «Download. Try.» нажмите на неё. Вы перейдёте на страницу с разными версиями для скачивания Qt, я выберу Open Source, там надо будет нажать на кнопку «Go open source».

Теперь вы переходите на другую страницу, где вам нужно скролить до самого низа, вы увидите кнопку «Download the Qt Online Installer», нажимаете на неё. Теперь когда вы проскролите немного в низ, увидите кнопку «Download», и у вас наконец начнёт скачиваться установщик.

Когда у вас скачался установщик, можете перейти к установке.

Установка Qt:

Для установки Qt правой кнопкой мыши два раза кликаем по установщику, который скачали выше.

Вам надо будет ввести Email и пароль от учётной записи Qt, поэтому если у вас её нет, надо будет зарегистрироваться, сделать это сможете по ссылке.

Далее нажимаете кнопку «Next», потом со всем соглашаетесь и опять нажимаете «Next», дальше выбираем, отправлять ли данные или нет, тут уже на свой выбор.

Я выбрал не отправлять данные, вам тоже рекомендую так сделать, нажимаем «Next», потом вам предложат выбрать путь до программы и способ установки.

Дальше вам нужно выбрать компоненты для установки, я выбрал для базовой работы, вы можете назначить другие.

Также нажимаете «Next», потом ещё раз со всем соглашаетесь и идёт установка. После того как установка прошла, можете начать работать.

Как возможно вы заметили, я устанавливал на Windows 10, но инструкция подойдёт и начиная с Windows 7.

Вывод:

В этой статье вы узнали как установить Qt на Windows 10, но и также для Windows 7 и 8, думаю вам было интересно и полезно.

Each software is released under license type that can be found on program pages as well as on search or category pages. Here are the most common license types:

Freeware

Freeware programs can be downloaded used free of charge and without any time limitations. Freeware products can be used free of charge for both personal and professional (commercial use).

Open Source

Open Source software is software with source code that anyone can inspect, modify or enhance. Programs released under this license can be used at no cost for both personal and commercial purposes. There are many different open source licenses but they all must comply with the Open Source Definition — in brief: the software can be freely used, modified and shared.

Free to Play

This license is commonly used for video games and it allows users to download and play the game for free. Basically, a product is offered Free to Play (Freemium) and the user can decide if he wants to pay the money (Premium) for additional features, services, virtual or physical goods that expand the functionality of the game. In some cases, ads may be show to the users.

Demo

Demo programs have a limited functionality for free, but charge for an advanced set of features or for the removal of advertisements from the program’s interfaces. In some cases, all the functionality is disabled until the license is purchased. Demos are usually not time-limited (like Trial software) but the functionality is limited.

Trial

Trial software allows the user to evaluate the software for a limited amount of time. After that trial period (usually 15 to 90 days) the user can decide whether to buy the software or not. Even though, most trial software products are only time-limited some also have feature limitations.

Paid

Qt — это кросс-платформенный фреймворк, с помощью которого можно создавать программное обеспечение, которое будет компилироваться в исполняемые файлы для различных операционных систем без изменения или с минимальным изменением кода. Первоначально платформа Qt создавалась для работы с кодом на языке программирования C++, однако вскоре появились наборы расширений для программирования на PHP, Python, Ruby и Java.

Являясь объектно-ориентированной средой программирования рассчитанной на мультиплатформенную разработку, Qt распространяется вместе с классами и библиотеками необходимыми для разработки элементов интерфейса в различных платформах, поддержки работы с сетью и подключения к базам данных, что делает его пригодным «из коробки» для создания большинства прикладных программ. Как и у большинства современных сред разработки и фреймворков, при необходимости функциональность Qt можно значительно расширить с помощью подключаемых плагинов и виджетов.

Фактически после выхода версии 4.5.0, которая получила интегрированный модуль Qt Creator, фреймворк стал представлять собой полноценную мультиплатформенную среду разработки в которой можно полноценно писать код, разрабатывать графические интерфейсы режиме визуального редактора с помощью модуля Qt Designer, разрабатывать кросс-платформенную справку воспользовавшись Qt Assistant и локализировать своё приложение на множество языков с благодаря модулю Qt Linguist.

Как и в случае с большинством свободно распространяемых программ, вы можете скачать исходный код Qt с официального сайта и собственноручно собрать нужные модули с персональными пожеланиями, однако в большинстве случае достаточно скачать Qt в виде автоматизированного установщика и просто выбрать, какие именно компоненты вам необходимы

Большинство модулей фреймворка Qt распространяются по лицензии LGPL v3 и GPL v3 с открытым исходным кодомLGPL v3 и GPL v3 с открытым исходным кодом и его можно скачивать и использовать бесплатно. При этом нужно иметь в виду, что лицензия некоторых модулей требует, чтобы создаваемый вами продукт так же распространялся под лицензией совместимой с GPL. Подробности лицензирования можно уточнить на официальном сайте фреймворка.

Язык C++ является компилируемым языком. Для преобразования текстового файла с программой в исполняемый exe-файл потребуется установить на компьютер специальную программу — компилятор. Для компиляции примеров из книги мы воспользуемся бесплатной программой g++.exe, входящей в состав популярной библиотеки MinGW, которая в свою очередь входит в состав библиотеки Qt.

Для загрузки библиотеки Qt переходим на сайт https://www.qt.io/ и нажимаем кнопку Download. Далее нажимаем кнопку из раздела Downloads for open source users. На следующей странице нажимаем кнопку Download the Qt Online Installer. Скачиваем программу установки и запускаем файл qt-unified-windows-x86-4.1.0-online.exe. Обратите внимание: для установки библиотеки потребуется активное подключение к сети Интернет.

После запуска программы установки отобразится окно, показанное на рис. 1.3. Вводим регистрационные данные или создаем новый аккаунт. Нажимаем кнопку Next. Если создавался новый аккаунт, то на адрес электронной почты придет письмо со ссылкой, позволяющей подтвердить адрес. Переходим по ссылке, а затем возвращается к программе установки и нажимаем кнопку Next.

На следующем шаге (рис. 1.4) устанавливаем флажки и нажимаем кнопку Next. В следующем окне (рис. 1.5) нажимаем кнопку Next. Далее нужно выбрать один из переключателей (рис. 1.6). Выбираем и нажимаем кнопку Next.. На следующем шаге (рис. 1.7) должен быть указан путь C:Qt и установлен флажок Custom installation. Нажимаем кнопку Next..

В следующем окне (рис. 1.8) устанавливаем флажок Latest releases. и нажимаем кнопку Filter. Затем в разделе Qt раскрываем список Qt 6.1.0 и устанавливаем флажок MinGW 8.1.0 64-bit. В разделе Developer and Designer Tools (рис. 1.9) устанавливаем флажки: Qt Creator 4.15.0 CDB Debugger Support, Debugging Tools for Windows и MinGW 8.1.0 64-bit. Нажимаем кнопку Next. В открывшемся окне (рис. 1.10) принимаем лицензионное соглашение и нажимаем кнопку Next. Затем (рис. 1.11) опять нажимаем кнопку Next. Нажимаем кнопку Install (рис.1.12) для запуска установки. После завершения установки нажимаем кнопку Finish (рис. 1.13).

В результате библиотека Qt будет установлена в каталог C:Qt6.1.0mingw81_64. В каталоге C:Qt6.1.0mingw81_64bin можно найти библиотеки, необходимые для работы оконных приложений. Библиотека MinGW будет установлена в каталог C:QtToolsmingw810_64. Программу g++.exe, предназначенную для компиляции программ, написанных на языке C++, можно найти в каталоге C:QtToolsmingw810_64bin.

В каталог C:QtToolsQtCreatorbin был установлен редактор QtCreator, который мы будем использовать для набора кода и сборки проектов. Запустить редактор можно с помощью файла qtcreator.exe. Если на последнем шаге мастера был установлен флажок, то редактор запустится автоматически.

Пути к каталогам C:QtToolsmingw810_64bin и C:Qt6.1.0mingw81_64bin можно добавить в системную переменную PATH. Однако мы этого делать не станем, чтобы можно было использовать сразу несколько компиляторов. Вместо изменения переменной PATH на постоянной основе мы будем выполнять изменение в командной строке только для текущего сеанса. Продемонстрируем это на примере, а заодно проверим работоспособность компилятора. Запускаем командную строку и выполняем следующие команды:

C:UsersUnicross>cd C:

C:>set Path=C:QtToolsmingw810_64bin;C:Qt6.1.0mingw81_64bin;%Path%

C:>gcc --version
gcc (x86_64-posix-seh-rev0, Built by MinGW-W64 project) 8.1.0
Copyright (C) 2018 Free Software Foundation, Inc.

C:>g++ --version
g++ (x86_64-posix-seh-rev0, Built by MinGW-W64 project) 8.1.0
Copyright (C) 2018 Free Software Foundation, Inc.
This is free software; see the source for copying conditions. 
There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A
PARTICULAR PURPOSE.

Первая команда (cd C:) делает текущим корневой каталог диска C:. Вторая команда (set Path=C:QtToolsmingw810_64bin;C:Qt6.1.0mingw81_64bin;%Path%) изменяет значение системной переменной PATH для текущего сеанса. Пути к каталогам C:QtToolsmingw810_64bin и C:Qt6.1.0mingw81_64bin мы добавили в самое начало переменной PATH. Третья команда (gcc --version) выводит версию программы gcc.exe. Эту программу можно использовать для компиляции программ, написанных на языке C. Четвертая команда (g++ --version) выводит версию программы g++.exe. Эту программу мы будем использовать для компиляции программ, написанных на языке C++. Фрагменты перед командами означают приглашение для ввода команд. Текст после команд является результатом выполнения этих команд.

Вместо выполнения отдельных команд можно написать скрипт, который выполняет сразу несколько команд и отображает результат их выполнения в отдельном окне. Запускаться такой скрипт будет с помощью двойного щелчка левой кнопкой мыши на значке файла. Для создания файла потребуется текстовый редактор, позволяющий корректно работать с различными кодировками. Советую установить на компьютер редактор Notepad++. Скачать редактор можно абсолютно бесплатно со страницы https://notepad-plus-plus.org/. Из двух вариантов (архив и инсталлятор) советую выбрать именно инсталлятор, т. к. при установке можно будет указать язык интерфейса программы. Установка Notepad++ предельно проста и в комментариях не нуждается.

Запускаем Notepad++ и создаем новый документ. Консоль в Windows по умолчанию работает с кодировкой windows-866, поэтому мы должны и файл сохранить в этой кодировке, иначе русские буквы будут искажены. В меню Кодировки выбираем пункт Кодировки | Кириллица | ОЕМ 866. Вводим текст скрипта (листинг 1.1) и сохраняем под названием script.bat в каталоге C:book. Запускаем скрипт с помощью двойного щелчка левой кнопкой мыши на значке файла script.bat. Результат выполнения показан на рис. 1.14. Для закрытия окна консоли достаточно нажать любую клавишу.

@echo off
title Заголовок окна
cd C:
echo Текущий каталог: %CD%
@echo.
set Path=C:QtToolsmingw810_64bin;%Path%
rem Вывод версии gcc.exe
echo gcc --version
@echo.
gcc --version
rem Вывод версии g++.exe
echo g++ --version
@echo.
g++ --version
pause

Рассмотрим инструкции из этого скрипта:

title — позволяет вывести текст в заголовок окна консоли;
echo — выводит текст в окно консоли;
@echo. — выводит пустую строку в окно консоли;
%CD% — переменная, содержащая путь к текущему рабочему каталогу;
%Path% — переменная, содержащая значение системной переменной PATH;
rem — вставляет комментарий, поясняющий фрагмент кода;
pause — ожидает ввода любого символа от пользователя. Если эту инструкцию убрать из скрипта, то программа выполнится и окно консоли сразу закроется, не дав нам возможности увидеть результат.

Feedback from our recent Qt for Beginners webinar series indicated a need for some basic tutorials for beginners. If you struggle with initially getting Qt set up for development with the Qt Creator IDE and a C++ compiler, this post is for you. I’ll walk you step by step through the process of getting a Qt development environment running on Windows, providing lots of screen shots to guide you.

Assumptions and Prerequisites

For this example I’ll assume you are running Windows 10. We will install the Open Source version of Qt 5.7.0 using the MinGW C++ compiler and the Qt Creator IDE. Installation should be similar if you use a different version of Windows or a different version of Qt. We will use the free MinGW compiler as it makes the setup easy, coming as part of the Qt install. You will need at least 5 GB of free disk space and an Internet connection in order to download the installer and Qt components. Let’s get started!

ICS recommends Qt Commercial for support, maximum IP protection, and because we all should support the community. (The Qt Company offers a free 30-trial version of Qt Commercial.)

Installation Steps

Fire up your web browser and go to http://qt.io. Click on «Download».

The website will ask you a few questions to determine whether you want the Open Source or commercial versions of Qt. To get the Open Source version select «Open source distribution under an LGPL or GPL license»

Say Yes to «Are you prepared to make your application source code publicly available?»

Say Yes to «Are you able to comply with the obligations of the LGPL v3 (or GPL v2/v3) and/or does your corporation allow open source usage?»

Then click on «Get started» and then «Download Now».

For a quicker way to download Qt and to get different versions other than the latest, you can instead go to http://download.qt.io. Select official_releases, then online_installers, and select to download qt-unified-windows-x86-online.exe

The download is reasonably small (18 MB) and will try to use a local server near you.

Once downloaded, run the installer program. You will probably need to accept the Windows dialog that requests permission to run the installer.

The installer will come up. Hit Next.

If you have a Qt online account, enter the information here. If you want to create one, go ahead. Otherwise just select Skip to proceed.

Click Next.

It will now download information about the available components from a remote server.

Pick the installation folder (the default is normally fine unless you need more disk space on another drive). A path with spaces in it or that is very long may cause problems later, so avoid doing that.

Now, choose the Qt components you want. Let’s do a minimal install. If you want more components you can select them. I expanded Qt 5.7, and under that section selected only MinGW 5.3.0 32-bit, turning off the rest of the checkboxes. The only other item I selected was under Tools, where Qt Creator 4.1.0 is always shown and is not optional.
Click Next.

Next read and accept the license agreement.

Then pick the Start menu shortcuts you want. The default is typically fine.

Installation is now ready, so select Next.

At this point it will download all the selected components. This will take a while depending on the speed of your Internet connection.

After downloads are completed it will start installing.

When done, click Finish and launch Qt Creator for the first time.

Qt Creator will launch and show the Welcome screen.

Qt Creator should auto-detect the Qt install and compiler and create a «kit» for desktop development. Look under Tools / Options Build & Run if you want to verify this.

We can now test the installation by creating a simple project. Let’s start with one for widgets: Select File / New File or Project…

Pick Application and Qt Widgets Application:

Click Choose… and pick a project name, such as demo1. Click Next.

Pick the kit (only one option is available) then Next.

You can specify some more information. Pick the defaults unless you want to use something else. Pick no project management.

You will now see the created skeleton application. You can look at the source code if desired: a main.cpp, mainwindow class header and cpp files, and a Qt Designer UI file.

Click the hammer icon at lower left to build it. You can click on Compiler Output if you want to see it. The project should successfully build.

You can now click on the green triangle icon to run it. After doing so, it should launch and you will see a window named MainWindow come up.

You might also want to try a QML application. Select File / New File or Project… and pick Application / Qt Quick Application (or whatever you prefer).

Build and run it as before.

If the above steps worked you are all set up to develop with Qt on the desktop. You can now create your own applications from scratch or start with one of the many examples or tutorials available within Qt Creator.

Under the Start menu you will see a Qt section with entries for Qt Creator, as well as Assistant, Designer and Linguist in case you want to run these tools on their own. There is also an entry for a command prompt for Qt, which will have qmake and other tools in the path so you can work from the command line if desired.

If you want to go back and add or remove more Qt components, run «Uninstall Qt» which is the maintenance tool we used earlier.

Select to Add or remove components or Update components.

Summary

I hope that you now appreciate that setting up Qt for desktop development is easy and you can be up and running very quickly. This example covered one of the most common setups. It is possible to use other compilers like Microsoft Visual Studio and even different IDEs if you desire. In the future I plan to continue this series for beginners, covering how to set up on a development environment on a Linux desktop and how to compile Qt from source.
