About displaying and validating data
When PowerBuilder generates a basic DataWindow object, it uses the extended
attributes defined for the data and stored in the extended attribute
system tables.
For more information about the extended attribute
system tables, see Appendix A, “The Extended
Attribute System Tables”
In the Database painter, you can create the extended attribute definitions that
specify a column’s display format, edit style, and validation
rules.
In the DataWindow painter, you can override these extended attribute definitions
for a column in a DataWindow object. These overrides do not change the
information stored with the column definition in the extended attribute
system tables.
