How to download and install Qt 5 for Windows 10
To download and install Qt 5 for Windows 10, you can follow these steps:
Step 1: Get a license to install Qt 5
You can choose between an open-source or a commercial license for Qt 5. The open-source license is free but has some restrictions on how you can use and distribute your applications. The commercial license is paid but has more functionality and flexibility. You can compare the licenses here. To get a license, you need to create a Qt Account or use your existing one. You can also use your Qt license key if you have one.
Step 2: Download the online or offline installer
You can download the online or offline installer for Qt 5 from the Qt Downloads page. The online installer allows you to select the components that you want to install, such as the latest versions and updates. The offline installer contains a pre-selected set of components and does not require an internet connection during installation. The size of the offline installer is larger than the online one. You can choose the installer that suits your needs and preferences.
Step 3: Run the installer and select the components
After downloading the installer, you need to run it and follow the instructions on the screen. You will need to accept the license agreement and choose the installation directory. If you are using the online installer, you will also need to select the components that you want to install. You can choose from different Qt versions, Qt modules, Qt tools, and additional components. You can also customize your installation by selecting or deselecting individual items. The installer will show you the disk space required for your selection.

How to create your first applications with Qt 5
Now that you have installed Qt 5, you can start creating your first applications with it. There are different ways to create applications with Qt 5, depending on your preferred programming language and UI framework. Here are some examples:
Getting started with Qt Widgets
If you want to create applications with a classic desktop-style UI using C++, you can use Qt Widgets. Qt Widgets provide a set of UI elements that can be customized and styled using CSS-like syntax. To create a simple Qt Widgets application, you can follow these steps:
Open Qt Creator and create a new project of type "Qt Widgets Application".
Choose a name and location for your project and select a kit (a combination of compiler, debugger, and device) to build and run your application.
Design your UI by dragging and dropping widgets from the Widget Box to the Form Editor. You can also edit the properties and signals of each widget using the Property Editor and the Signal/Slot Editor.
Write your application logic by editing the source code files in the Code Editor. You can use the Qt documentation and examples to learn more about the Qt API and features.
Build and run your application by clicking on the green arrow button or pressing Ctrl+R. You can also debug your application by clicking on the bug icon or pressing F5.
Getting started with Qt Quick
If you want to create applications with a modern and fluid UI using QML (a declarative language for designing UIs) and JavaScript, you can use Qt Quick. Qt Quick provides a set of UI elements that can be animated and integrated with C++ code. To create a simple Qt Quick application, you can follow these steps:
Open Qt Creator and create a new project of type "Qt Quick Application - Empty".
Choose a name and location for your project and select a kit (a combination of compiler, debugger, and device) to build and run your application.
Design your UI by editing the QML file in the Design mode or the Text mode. You can use QML types from various modules, such as Qt Quick Controls, Qt Quick Layouts, Qt Graphical Effects, etc.
Write your application logic by adding JavaScript code within the QML file or by creating separate JavaScript files. You can also use C++ classes and objects in your QML code by registering them with the QML engine.
Build and run your application by clicking on the green arrow button or pressing Ctrl+R. You can also debug your application by clicking on the bug icon or pressing F5.
Getting started with QML and C++
If you want to create applications that combine QML UIs with C++ logic, you can use both QML and C++ in your project. This way, you can leverage the advantages of both languages and frameworks. To create a simple QML and C++ application, you can follow these steps:
Open Qt Creator and create a new project of type "Qt Quick Application".
Choose a name and location for your project and select a kit (a combination of compiler, debugger, and device) to build and run your application.
Design your UI by editing the QML file in the Design mode or the Text mode. You can use QML types from various modules, such as Qt Quick Controls, Qt Quick Layouts, Qt Graphical Effects, etc.
Write your C++ logic by editing the source code files in the Code Editor. You can use the Qt documentation and examples to learn more about the Qt API and features.
Expose your C++ classes and objects to QML by registering them with the QML engine. You can also use signals and slots to communicate between QML and C++.
Build and run your application by clicking on the green arrow button or pressing Ctrl+R. You can also debug your application by clicking on the bug icon or pressing F5.
