notifyPage

Procedure that invokes the specified procedure in all objects on the CurrentPage of A SmartContainer.

Location: containr.p

Parameters:

INPUT pcProc AS CHARACTER

The internal procedure to run.

Notes:

This procedure is necessary because paging does not work well with PUBLISH/SUBSCRIBE. For example, although all objects in a Container subscribe to initialize (and so on), the paging performs the operation on subsets of those objects.
The notifyPage procedure uses the PageNtargets property values to run an event procedure in all the objects on the current page.
Examples:

/* This code fragment from changePage causes initializeObject to be run    in each newly created object on a page selected for the first time.    NotifyPage effectively does a PUBLISH to each object on the current    page. */ {get ObjectInitialized lInitted}. /* Is the container itself initialized? */ IF lInitted THEN    RUN notifyPage In TARGET-PROCEDURE (“initializeObject”:U).
