| Description |
A TOption5 object is a cover object for the APL+Win Option object.
Its main additional feature is to support input validation and validation error messages
To do so, you must set the <handler> property of the parent form and write your validation
check in the <handler> function for the onClick event on the TOption5 object.
Example:
'ff'Świ'handler' 'Test_Handlers'
and in the Test_Handlers function, the following sample lines would prevent the user
from selecting the option1 radio button if the edSalary field contains a value larger than 10000:
Źoption1_onClick:
:if ‘option1^‘edSalary>10000
Śwres„'You cannot check this radio button if your salary is > 10000!'
:end
:return
