How does the message hierarchy differ from HyperCard?

SuperCard's message hierarchy is similar to HyperCard's, with a HyperCard stack being functionally equivalent to a SuperCard window. There is also the addition of a new level to this hierarchy, called the Project, which serves as a container for the windows, menus and resources which make up a project. A diagram of the message-passing hierarchy might look like this: keyboard mouse menu item message box --------------- ----- --------- ----------- | | | | | ---------- -------------------- | | | field | | button graphics | menu | ---------- -------------------- | | | | | | ---------------------------------------------- | current card | current background | current window | current project | project XCMD or XFCN | SharedFile | SharedFile XCMD or XFCN | SuperCard Also, SuperCard does not implement the "dynamic path." Therefore, when you go to a new card, the new scripts are not part of the current hierarchy. Use the send command to pass messages to the new card, if necessary.
