Modern accelerated GUI

HikoGUI GUI library

A portable, low latency, retained-mode GUI framework written in C++

I started this library to make a portable, low latency and modern looking UI framework, which may also be used in proprietary (closed source) applications.

It is specifically designed to display information with low-latency, and at the screen's refresh rate. Special care is taken for making it easy for GUI element to observe and modify data external to the GUI.

You can find a lot more information, documentation, example code, news and blog posts on the main web site: https://hikogui.org/

Features

• High level API to make simple desktop applications.
• Modern C++20 library.
• Retained-mode GUI.
• GUI will dynamically track the state of the application.
• Localization and translation.
• Animation at the screen's refresh rate.
• Themes; including light/dark support.
• Editable key-bindings.

• Most or all drawing is GPU accelerated with Vulkan.
• Text is drawn using kerning, perceptional correct blending and subpixel anti-aliasing.
• High dynamic range and high gamut color handling.

• Automatic application preferences storage.
• Many support systems:
  • logging,
  • statistics,
  • text handling,
  • text template language,
  • expression language,
  • dynamic type system.

Example

Here is some example code for an application with three radio buttons, who form a set by sharing a single value observer.

int hi_main(int argc, char *argv[])
{
    observer<int> value = 0;

    auto gui = hi::gui_system::make_unique();
    auto &window = gui.make_window(txt("Radio button example"));
    window.content().emplace<label_widget>("A1", txt("radio buttons:"));
    window.content().emplace<radio_button_widget>("B1", txt("one"), value, 1);
    window.content().emplace<radio_button_widget>("B2", txt("two"), value, 2);
    window.content().emplace<radio_button_widget>("B3", txt("three"), value, 3);

    return gui->loop();
}
