Type Function
Description Displays a simple non-blocking dialog box using NSAlert and a hidden hs.webview that's automatically destroyed when the alert is closed.
Parameters
  • x - A number containing the horizontal co-ordinate of the top-left point of the dialog box. Defaults to 1.
  • y - A number containing the vertical co-ordinate of the top-left point of the dialog box. Defaults to 1.

  • message - The message text to display.
  • [informativeText] - Optional informative text to display.
  • [buttonOne] - An optional value for the first button as a string. Defaults to "OK".

  • Example:
  • lua</li><li> testCallbackFn = function(result) print("Callback Result: " .. result) end</li><li> hs.dialog.alert(100, 100, testCallbackFn, "Message", "Informative Text", "Button One", "Button Two", "NSCriticalAlertStyle")</li><li> hs.dialog.alert(200, 200, testCallbackFn, "Message", "Informative Text", "Single Button")
