I have the following code to display a prompt dialog in which text can be entered after a user clicks a button. The prompt dialog shows 2 buttons: OK and Cancel. Whatever button I click, the program never gets into the event listener function 'onPromptButtonClicked' (I don't see the text "Hello world" in the debugging output).

What am I doing wrong here?

private function onBtnAddTextClicked (event:MouseEvent):void {
  var promptromptDialog = new PromptDialog();
 
  prompt.title = "Title";
  prompt.message = "Please enter text:";
  prompt.addButton("OK");
  prompt.addButton("Cancel");
  prompt.addEventListener(DialogEvent.DIALOG_BUTTON_CLICKED, onPromptButtonClicked);
  prompt.show();
}

private function onPromptButtonClicked(eventialogEvent):void {
 trace("Hello world");
}

hey eugenevk,

yeah unfortunately this is a bug and hopefully gets fixed soon. it was discussed on the forums prior and a work around for it was the following:

Replace:

prompt.addEventListener(DialogEvent.DIALOG_BUTTON_CLICKED, onPromptButtonClicked);

with:

prompt.addEventListener(Event.SELECT, onPromptButtonClicked);

and it should do what you need it to do. here is a thread for reference if you need more information:

hope that helps. good luck!

Super, that works. Was breaking my head on it.

JRab, would you also know how to use/access the value of the text entered in the input field of the prompt dialog in de event handler function?

hey eugenvk,

sure thing! you would request the prompt object's text property by doing the following:

private var prompt:PromptDialog; // placed outside of your main application constructor

(...)

private function onBtnAddTextClicked (event:MouseEvent):void {
	
	prompt = new PromptDialog();
	
	prompt.title = "Title";
	prompt.message = "Please enter text:";
	prompt.addButton("OK");
	prompt.addButton("Cancel");
	prompt.addEventListener(Event.SELECT, onPromptButtonClicked);
	prompt.show();
}

private function onPromptButtonClicked(event:Event):void {
	trace(prompt.text);
}

the only thing to remember is to place your prompt dialog object declaration outside of the the constructor in order to have access to it by other functions such as the onPromptClicked(). hope that helps. good luck!

Thanks again!

Expected that, but thought there might be another way. I did btw the following, which works as well:

prompt.addEventListener(Event.SELECT, function onPromptButtonClicked(event:Event):void{
   var btnOKClicked:Boolean = (event.target.selectedIndex == 0);

   if (btnOKClicked && (prompt.text != "")) {
      trace(prompt.text);
   }
});

Rgrds,

hey eugenevk,

you're absolutely right there is another method. if you go back to your old code, you can refer to the text as event.target.text. event.target being your dialog since thats where the event orginated from. sorry for the brain fart hah!

private function onPromptButtonClicked(event:Event):void
{
	trace(event.target.text);
}
