Golang : Qt Yes No and Quit message box example

A quick tutorial on how to create simple dialog box and message box with Yes, No and Quit buttons. Pretty useful in asking user for confirmation.

Here you go!

Example 1:

 package main

 import (
 "fmt"
 "github.com/therecipe/qt/core"
 "github.com/therecipe/qt/widgets"
 "os"
 )

 var (
 mainApp *widgets.QApplication
 mainLayout *widgets.QWidget
 )

 func populate() *widgets.QWidget {

 mainLayout = widgets.NewQWidget(nil, 0)

 yesButton := widgets.NewQPushButton2("Yes", nil)
 yesButton.ConnectClicked(func(flag bool) {
 fmt.Println("Yes!")
 })

 noButton := widgets.NewQPushButton2("No", nil)
 noButton.ConnectClicked(func(flag bool) {
 fmt.Println("No!")
 })

 quitButton := widgets.NewQPushButton2("Quit", nil)
 quitButton.ConnectClicked(func(flag bool) {
 mainApp.Quit()
 })

 layout := widgets.NewQVBoxLayout()
 layout.AddWidget(yesButton, 0, core.Qt__AlignLeft)
 layout.AddWidget(noButton, 0, core.Qt__AlignLeft)
 layout.AddWidget(quitButton, 0, core.Qt__AlignRight)

 mainLayout.SetLayout(layout)
 return mainLayout
 }

 func main() {

 mainApp = widgets.NewQApplication(len(os.Args), os.Args)

 populate().Show()

 mainApp.Exec()
 }

and example 2 is with QMessageBox and QMessage__StandardButton

 package main

 import (
 "fmt"
 "github.com/therecipe/qt/core"
 "github.com/therecipe/qt/widgets"
 "os"
 )

 var (
 mainApp *widgets.QApplication
 mainLayout *widgets.QWidget
 replyBox *widgets.QMessageBox
 replyButtons *widgets.QMessageBox__StandardButton
 )

 func populate() *widgets.QWidget {

 mainLayout = widgets.NewQWidget(nil, 0)
 replyBox := widgets.NewQMessageBox(nil)
 replyButtons := replyBox.Question(nil, "Test", "Quit", widgets.QMessageBox__Yes, widgets.QMessageBox__No)

 if replyButtons == widgets.QMessageBox__Yes {
 fmt.Println("Yes! Quit")
 // mainApp.Quit() -- strange won't work!
 os.Exit(0)
 } else {
 fmt.Println("No!")
 }

 layout := widgets.NewQVBoxLayout()
 layout.AddWidget(replyBox, 0, core.Qt__AlignLeft)
 mainLayout.SetLayout(layout)
 return mainLayout
 }

 func main() {

 mainApp = widgets.NewQApplication(len(os.Args), os.Args)

 populate().Show()

 mainApp.Exec()
 }
