giu

Cross platform rapid GUI framework for golang based on Dear ImGui and the great golang binding imgui-go.

Supported Platforms

The supported platforms depends on GLFW v3.3, so idealy giu could support all platforms that GLFW v3.3 supports.

• Windows (only tested on Windows 10 x64)
• MacOS (only tested on MacOS v10.15)
• Linux (thanks remeh to test it)
• Raspberry pi 3b (thanks sndvaps to test it)

Features

Compare to other Dear ImGui golang bindings, giu has following features:

• Live-update during the resizing of OS window (implemented on GLFW 3.3 and OpenGL 3.2).
• Redraw only when user event occurred. Costs only 0.5% CPU usage with 60FPS.
• Declarative UI (see examples for more detail).
• DPI awareness (auto scale font and UI to adapte high DPI monitor).
• Drop in usage, no need to implement render and platform.
• Freetype font rendering support.
• OS clipboard support.
