The message-passing order
The message-passing order
If an object receives a message for which it doesn't have a handler, NovoCard passes the message to other objects and searches their scripts for a handler that matches the current message. The order in which NovoCard passes a message to objects is called the message-passing order or the message-passing path.
NovoCard send messages to a specific object (button, field, picture, portal, shape, or current card). If the object doesn't handle the message, it goes to the following objects, in order:
• the current card (if the card is not the target)
• the current background
• the current stack
• the stack script of the Home stack
• NovoCard itself
