GUI, Introduction and List

Qt

Qt, acquired by Nokia and then Digia, was originally used in the KDE interface in Linux. It has spread to all systems and is now the basis for programming applications for mobile devices by Nokia. The toolkit, QtClick, provides ready-made code.
Starting with version 5.1, applications also run on Android and iOS.

Advantages

• Full API.
• Quicky.
• OpenGL and WebKit components.
• QML interface language.
• High tolerability.
• Several possible programming languages.
• Enables 3D animation.
• QtCreator development visual interface.
• Can be used on (some) mobile devices.
• Good documentation.

Inconveniences

• Very heavy download file for the user.
• Free license for open source projects only.

JavaFX

The Java programming language library includes all components useful for the user interface. In addition, there is a JavaFX - GUI to simplify the creation of user interfaces.
Java classes can be used in an application in C or PHP.

Advantages

• Full API for desktop or Internet.
• Several development tools (see resources).
• Tolerability.
• Google's GWT framework for the Web (converts Java to JavaScript).

Inconveniences

• Java is quite difficult to use outside of JavaFX.
• Not particularly fast .

WPF и WinRT

WPF is a .NET graphical and hardware interface layer whose API provides access to all Windows services. WinRT is the runtime of Windows 8.

Advantages

• There is nothing to download for the user.
• XAML or HTML 5 interface language.
• Simple programming with Visual Studio.
• Visual development tools for various languages, including C # and JavaScript
.

Cons.

• Works only on Windows. WPF portals under other systems are incomplete and are not available for WinRT.
• Slower to execute than native.

STATE CUSTOMS COMMITTEE

Gnome graphics framework in Linux, worn under Windows. The most famous Windows application using this framework is Gimp, and it is available on all operating systems.
There is a GTK port for PHP, but it is not updated with chandeliers and requires a modified version of runtime .
GTK is considered less convenient than Qt, with equivalent capabilities and more complex programming.

Electron

To create a local application with web technologies: Chrome browser for rendering, HTML and CSS for describing the interface and JavaScript on the server and interface side. This also includes the libuv library for accessing the file system and all Node.js extensions.
This is an absolutely portable and simple solution.
Use cases can be found in Advanced Explorer and the Advanced Editor code editor on this site.

Aura

Developed by Google to replace GTK to give Chrome and ChromeOS a portable framework, in particular running on Linux and Android.
It is based on OpenGL and opens context to each window rather than tabs to save resources.
The aura is probably not easy to use for the app because it is made for the browser, but since the trend is to use the browser as an interface to the system (which ChromeOS does), this infrastructure is indirectly universal.
It can also be argued that the SCC was designed for Gimp and became universal, the Aura could follow the same route.

ImGui

If you are looking for a very easy-to-implement interface library for a C++ application, ImGui can be a solution. The code is as simple as this:

ImGui::InputText("string", buffer, 128);

Click [TAG] OK [TAG] to display the input text box and control its operation. The library contains graphics functions. It uses OpenGL intensively, and this may not be appropriate for some applications. That's the cost of its minimal reliance on other bookstores .
ImGui is well suited for the game interface, full-screen applications.

See also: Nuclyar. Made in C, it's very light, around 15KB, but full.

GuiLite

A simple and economical library (about 5KO) written in C++ for all platforms. Visual Studio Code has an interface preview tool.

Advantages

• Ease of use.
• Various possible programming languages.
• Mobile on the table and mobile.
• Customizable.
• Does not use the framework to display its own widgets.

Tcl/Tk

Tcl is a programming language, and Tk is a graphical toolkit that works with Tcl or other languages.

Advantages

• Ease of use.
• Different programming languages can be used as needed.
• Mobile.

Inconveniences

• Tcl is a dynamic language, so slower.
• Tk is for Tcl.

FTLC

Toolbar for creating graphical interfaces in C++.

Advantages

• Portable (Windows, Linux, Mac and others).
• Easy.
• Supports OpenGL.
• FLUID Visual Interface Editor.

Inconveniences

• Less complete than previous alternatives.
• Limited to programming language.

wxWidget

Toolkit for Windows, Linux, Mac based on GTK, but using its own widgets. Used with different programming languages. There are disadvantages due to the lack of flexibility.
In November 2013, version 3.0 was released, the first updated since 1998! This proves that the project is still alive, and the last update is dated 2018.

FOX Toolkit

Toolbar for creating C++ interfaces. It is worn under Windows, Linux and other Unix.
Can help give Windows the look and feel of Linux applications.

SDL

A library for programming games that uses all computer resources (video, sound, devices), all languages ​ ​ and operating systems. This portable framework provides access to OpenGL and devices .
The programming language can be selected from several, including PHP, C++, Java.
For Windows, Linux.

OpenGL

Portable graphics library is an alternative to DirectX for optimal performance. It interacts with the graphics card, and the user must have a version for his graphics card if it is not already installed by the seller.
There is an OpenGL interface for browsers, WebGL.

You can use the toolbar with libraries in this list to create your own components. This will not come close to Qt simplicity, but it will be much easier.

Willock

First, the Greek letters are pronounced Chi and Ro by the name Xr, which gave the new name.
Vector Graphics API. Compatible with many systems and programming languages.
This is the interface between toolkit and OpenGL or DirectX.

WebKit

The Chrome and Safari rendering engine can also be used directly by the application and show HTML 5. There is a WebKit component in Qt.

The Chromium Embedded project allows, together with QtWebkit, to integrate the browser into the application and use HTML 5 as the interface language. After that, the shipowner will be displayed as an object in the scenery.
But a simpler solution would be to use Electron, which does the same and offers an additional API.

Clutter

The feature library supported by Intel and originally intended for the Meego mobile system is not too cumbersome. It is actually an OpenGL interface that makes it easier to use. It has an Mx tool box (since QT has QtClick). The programming language is C++ or Python. The project is now associated with Gnome.

DirectX

Interface for Windows audio and graphics devices.
