gocoa

Go bindings for the Cocoa framework to build macOS applications.

How to use

The following is a basic Hello World application.

package main

import (
    "fmt"

    "github.com/mojbro/gocoa"
)

func main() {
    gocoa.InitApplication()
    gocoa.OnApplicationDidFinishLaunching(func() {
        fmt.Println("App running!")
    })
    wnd := gocoa.NewWindow("Hello World!", 150, 150, 300, 200)

    // Change me button
    currentTitle, nextTitle := "Change me!", "Change me again!"
    changeButton := gocoa.NewButton(75, 125, 150, 25)
    changeButton.SetTitle(currentTitle)
    changeButton.OnClick(func() {
        changeButton.SetTitle(nextTitle)
        currentTitle, nextTitle = nextTitle, currentTitle
    })
    wnd.AddButton(changeButton)

    // Quit button
    quitButton := gocoa.NewButton(75, 50, 150, 25)
    quitButton.SetTitle("Quit")
    quitButton.OnClick(func() { gocoa.TerminateApplication() })
    wnd.AddButton(quitButton)

    wnd.MakeKeyAndOrderFront()
    gocoa.RunApplication()
}

Status of this project

This package is very, very early and incomplete! It is mostly just an experiment and is not really useful yet.
