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()
}
