Automatic Data Validation of Sibling Parts in Reusable
A method for
accomplishing data validation of graphical user
interface parts without program logic is disclosed.
used graphical user interface parts are entry
fields and push buttons. Entry fields are parts which allow a user
of a computer program to enter textual information. Entry fields can
be modified so that an entry field will only accept values within a
specific range of values.
an entry field can be defined to accept numeric
values which fall between the values of 10 and 20. A user enters
each numeric digit into an entry field until an entire number has
been entered. For instance, if a user wants to enter the number 12,
the user would first enter the 1, followed by the 2. As the user of
the program is entering characters into the entry field, the entry
field does not know when the entry is complete. The entry field
first sees the 1 entered. However, the 1 by itself is not within the
range of accepted values. The entry field cannot reject the entry
since it knows that more digits could be entered after the 1.
To circumvent this problem, a software programmer would
1. Present an entry field part and a push button part to the user.
The push button is to be pushed by the user when the entry has
2. When the push button is pushed by the user, th...
