In C++, there are numerous different GUI libraries available, each with its own usage and features. Here are some common examples of how to use C++ GUI libraries.

  1. Qt is a cross-platform GUI library for developing graphical interface applications, offering a variety of components and tools to quickly create windows, buttons, text boxes, tables, and more. It is written in C++ and allows for creating and configuring GUI components, handling user input, defining signals and slots, and more.
  2. wxWidgets is another cross-platform GUI library that can be used for developing graphical interface applications. It offers GUI components and tools similar to Qt, allowing users to create various elements such as windows, buttons, text boxes, and tables. Like Qt, wxWidgets is written in C++, with similar usage in creating and configuring GUI components, handling user input, and defining event handling functions.
  3. WinAPI: WinAPI is a set of APIs provided by the Windows operating system that can be used to create graphical interfaces for Windows applications. It is written in C or C++ and is primarily used on the Windows platform. The use of WinAPI includes creating and configuring windows, handling window messages, drawing graphics, and more. Due to its low-level nature, WinAPI is relatively complex to use but allows for more precise control over the behavior of applications.
  4. GTK+ is a cross-platform GUI library used for developing graphical interface applications. It is written in C but also offers C++ binding libraries. GTK+ provides a variety of GUI components and tools for creating windows, buttons, text boxes, tables, etc. Its functionality includes creating and configuring GUI components, handling events, defining callback functions, and more.

The above are brief introductions to several common C++ GUI libraries, each with more detailed documentation and sample code for reference. Choosing the right GUI library depends on your project requirements, platform support, and personal preferences.
