Calling a method after a Textbox is closed

   //This class is a subclass to the DialogueBox and can thus be used in place of it
   //The DialogueBox is being used whenever a question pops up or a message is being displayed until you click it away
   //This subclass is only for messages though, because the question variant already calls a
   //function when an answer has been selected.
   class ResponsiveDialogueBox : DialogueBox
   {
       //The function that should be executed, after the dialogue is being closed
       //A method with no parameters which returns void
       //If you want to execute a function with parameters or a return type build a 'shell' around it
       //and set the shell as the AfterDialogueFunction:
       //(in this example 'this' is the object you want your function to be called in)
       //
       // AfterDialogueFunction()
       // {
       //  this.someValueToSet = yourOwnFunction(this.ParameterFromSomewhere);
       // }
       
       //The property which holds the function which should be invoked after the box is closed
        private Action AfterDialogueFunction { get; set; }

       //message to the base class, so that a normal DialogueBox is being displayed
