A message box contains an application-defined message (prompt) and title, plus a combination of predefined icons and push buttons. The App.showMsgBox not only makes it possible to display these message boxes but to find out which button the user pressed to close the message box. This allows you to get simple answers from with your users in a way they are familiar with and with very little effort.


The following example opens a message box with Yes and No buttons. The value of the chosen button is displayed in the SWF Studio Trace tab.

// Make sure the window is visible.;

var return_obj = ssCore.App.showMsgBox({icon:"question", buttons:"YesNo", defaultButton:"button2", prompt:"Are you sure?"});
