giu

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

Any contribution (features, widgets, tutorials, documents and etc...) is appreciated!

Supported Platforms

giu is built upon 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:

• Small executable file size (<3mb after upx compression for the example/helloworld demo).
• 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.

Hello world

package main

import (
	"fmt"

	g "github.com/AllenDang/giu"
)

func onClickMe() {
	fmt.Println("Hello world!")
}

func onImSoCute() {
	fmt.Println("Im sooooooo cute!!")
}

func loop() {
	g.SingleWindow("hello world").Layout(
		g.Label("Hello world from giu"),
		g.Line(
			g.Button("Click Me").OnClick(onClickMe),
			g.Button("I'm so cute").OnClick(onImSoCute),
		),
	)
}

func main() {
	wnd := g.NewMasterWindow("Hello world", 400, 200, g.MasterWindowFlagsNotResizable, nil)
	wnd.Run(loop)
}

Here is result.
