/*
Package gui implements a abstraction layer for Go visual elements.
Definitions:
* Toolkit: the underlying GUI library (MacOS gui, Windows gui, gtk, qt, etc)
* Node: A binary tree of all the underlying widgets
Principles:
* Make code using this package simple to use
* Hide complexity internally here
* Isolate the GUI toolkit
* Widget names should try to match [Wikipedia Graphical widget]
* When in doubt, search upward in the binary tree
* It's ok to guess. Try to do something sensible.
Quick Start
// This creates a simple hello world window
package main
import (
"log"
"git.wit.org/wit/gui"
)
var window *gui.Node // This is the beginning of the binary tree of widgets
// go will sit here until the window exits
func main() {
gui.Init()
gui.Main(helloworld)
}
// This initializes the first window and 2 tabs
func helloworld() {
gui.Config.Title = "Hello World golang wit/gui Window"
gui.Config.Width = 640
gui.Config.Height = 480
window := gui.NewWindow()
addTab(window, "A Simple Tab Demo")
addTab(window, "A Second Tab")
}
func addTab(w *gui.Node, title string) {
tab := w.NewTab(title)
group := tab.NewGroup("foo bar")
group.NewButton("hello", func() {
log.Println("world")
})
}
Debian Build
This worked on debian sid on 2022/10/20
I didn't record the dependances needed
GO111MODULE="off" go get -v -t -u git.wit.org/wit/gui
cd ~/go/src/git.wit.org/wit/gui/cmds/helloworld/
GO111MODULE="off" go build -v -x
./helloworld
Toolkits
* andlabs - https://github.com/andlabs/ui
* gocui - https://github.com/awesome-gocui/gocui
The next step is to allow this to work against go-gtk and go-qt.
TODO: Add Fyne, WASM, native macos & windows, android and
hopefully also things like libSDL, faiface/pixel, slint
