Documentation

Overview

Package that contains variety of dialogs

Example of using InputDialog

input := make(chan string)
//Prevents nested dialogs and other glitches (like double handler call)
for _, view := range gui.Views() {
	gui.DeleteKeybindings(view.Name())
}
utils.ErrCheck(
	mngr.SelectView(
		gui,
		dialog.InputDialog("Are you sure? [y/n]", "", "", gui, input).Name()))
go func() {
	if userInput, ok := <-input; ok {
		log.Print(userInput)
	}
	SetKeyBindings(gui, mngr)
}()

Similar example for ConfirmDialog

option := make(chan bool)
previousView := gui.CurrentView()
log.Println("callback: ", previousView.Name())
//Prevents nested dialogs and other glitches (like double handler call)
for _, view := range gui.Views() {
	gui.DeleteKeybindings(view.Name())
}
utils.ErrCheck(
	mngr.SelectView(
		gui,
		dialog.ConfirmDialog("message", "title", gui, option).Name()))

go func() {
	if choice, ok = <-option; ok {
		log.Printf("Choosen option: %v", choice)
	}

	mngr.currView = previousView
	log.Println("thread: ", mngr.currView.Name(), previousView.Name())
	SetKeyBindings(gui, mngr)
}()

Remember! When user chooses an option, it deletes returned view, so make sure to handle it properly. If you don't, it may cause Unknown view error
