# Quick Start

1. Create a folder `[GOPATH]/src/qtExample`

2. Create a file `[GOPATH]/src/qtExample/main.go`
```go
package main

import (
	"os"

	"github.com/therecipe/qt/widgets"
)

func main() {
	widgets.NewQApplication(len(os.Args), os.Args)

	var btn = widgets.NewQPushButton2("Hello World", nil)
	btn.Resize2(180, 44)
	btn.ConnectClicked(func(flag bool) {
		widgets.QMessageBox_Information(nil, "OK", "You Clicked me!", widgets.QMessageBox__Ok, widgets.QMessageBox__Ok)
	})

	var window = widgets.NewQMainWindow(nil, 0)
	window.SetWindowTitle("Hello World Example")
	window.Layout().AddWidget(btn)
	window.Show()

	widgets.QApplication_Exec()
}
```

3. Open the command line in `[GOPATH]/src` and run
`qtdeploy build desktop qtExample`

4. Wait a minute, then you will find the executable file here
`[GOPATH]/src/qtExample/deploy/[GOOS]/qtExample`

5. Take a look at the [other examples](https://github.com/therecipe/qt/tree/master/internal/examples)

6. Make yourself familiar with the [qt documentation](https://doc.qt.io/qt-5/classes.html)
