이번엔 인터넷에서 go-sciter를 이용한 간단한 계산기 프로그램을 우연히 발견하여 이를 투명하게 개조해보았습니다.

참고로 이번 프로그램에는 컬러값을 설정할 때 "github.com/fatih/color" 라는 패키지가 필요합니다.

go get "github.com/fatih/color"

를 수행해서 추가로 필요한 패키지를 설치해 줍니다.

 

그리고 아래 코드를 작성해줍시다.

 

1. main.go

package main

import (
	"fmt"

	"github.com/fatih/color"
	sciter "github.com/sciter-sdk/go-sciter"
	"github.com/sciter-sdk/go-sciter/window"
)

// Specifying  havily used
// Singltons to make them
// package wide available
var root *sciter.Element
var rootSelectorErr error
var w *window.Window
var windowErr error

// Preapare Scitre For Execution ///
func init() {

	// initlzigin window for downloaer
	// app with appropriate properties
	rect := sciter.NewRect(0, 100, 200, 350)
	w, windowErr = window.New(sciter.SW_TITLEBAR|
		sciter.SW_CONTROLS|
		sciter.SW_MAIN|
		sciter.SW_GLASSY,
		rect)

	if windowErr != nil {
		fmt.Println("Can not create new window")
		return
	}
	// Loading main html file for app
	htloadErr := w.LoadFile("./main.html")
	if htloadErr != nil {
		fmt.Println("Can not load html in the screen", htloadErr.Error())
		return
	}

	// Initializng  Selector at global level as we  are going to need
	// it mostly and as it is
	root, rootSelectorErr = w.GetRootElement()
	if rootSelectorErr != nil {
		fmt.Println("Can not select root element")
		return
	}

	// Set title of the appliaction window
	w.SetTitle("Simple Calc")

}

// Preaprare Program for execution ///
func main() {

	addbutton, _ := root.SelectById("add")

	out1, errout1 := root.SelectById("output1")
	if errout1 != nil {
		color.Red("failed to bound output 1 ", errout1.Error())
	}
	addbutton.OnClick(func() {
		output := add()
		out1.SetText(fmt.Sprint(output))
	})

	w.Show()
	w.Run()

}

//////////////////////////////////////////////////
/// Function of calc                           ///
//////////////////////////////////////////////////

func add() int {

	// Refreshing and fetching inputs()
	in1, errin1 := root.SelectById("input1")
	if errin1 != nil {
		color.Red("failed to bound input 1 ", errin1.Error())
	}
	in2, errin2 := root.SelectById("input2")
	if errin2 != nil {
		color.Red("failed to bound input 2 ", errin2.Error())
	}

	in1val, errv1 := in1.GetValue()
	color.Green(in1val.String())

	if errv1 != nil {
		color.Red(errv1.Error())
	}
	in2val, errv2 := in2.GetValue()
	if errv2 != nil {
		color.Red(errv2.Error())
	}
	color.Green(in2val.String())

	return in1val.Int() + in2val.Int()
}

2.main.html

<html window-frame="transparent" window-blurbehind>
<head>
    <head>
        <title>Simple Calc</title> 
        <meta name="viewport" content="width=device-width, initial-scale=1.0">  
        <style>
          html{
            background: transparent;
          }
          div{
            color: white;
            text-align: right;
          }
        </style>
    </head>
</head>
<body>
    <div>
      <label for="">No1</label>
      <input type="number" style="width: 100px; margin: 0 auto;" id="input1" >
      <br>
      <label for="">No2</label>
      <input type="number" style="width: 100px; margin: 0 auto;" id="input2" >
      <br>
      <input type="button" style="width: 50px; margin: 0 auto;" value="Add ( + )" id="add"> 
      <hr>
      <input type="number" style="width: 100px; margin: 0 auto;" id="output1" disabled>
    </div>

</body>
</html>

 

실행결과는 ..

 

 

 

투명하게 나오니까 역시 이쁘네요.

오늘은 여기까지~~
