I want to thank everybody for the hints - some were really useful :-)
The major common point of all suggestions was to use *global*
pointers. I thought I could avoid this. Internally (in XForms) there
are pointers to the first and the last object of a form. My solution
(before I started this thread here) was to search the linked pointers
from FL_FORM->first to FL_FORM->last (see "forms.h"). I built a loop
and 'switch'-ed all classes and (within the classes) all the types.
So I could find any object in any form and identify it. The own
thing missing was/is a possibility to distinguish:
"is this the customer form's name field"
or
"is this the customer form's street field"
Maybe I was misunderstood a bit (I'm german and can't express myself
in english as I can in german). Here are the thoughts which invoked
my first mail concerning field updating:
XForms provides many functions for all purposes (event handling,
signals, I/O redirection and much more). So I simply expected some
functions to access objects other than the current one.
Therefore I expected something like a (unique) object ID or an
internal object name, so that I could reference to it e.g.
"update customers 'first name' field"
"take customers 'custom_id' field and build an SQL query with it"
"initialize form 'customer' with default values"
"push control panels 'exit' button"
Maybe it's useful to add an 'object ID' to the FL_OBJECT structure?
Have a nice weekend, everybody on the list :-)
Frank.
