Get() > Instance variables |
Code block to validate a value before Get receives input focus.
Data type: | B | Default: | NIL |
Optionally, a code block can be assigned to :preValidate that is used to test if a Get object may receive input focus. The code block receives as parameter the Get object and must return a logical value. When the code block returns .T. (true), the Get object receives input focus. When it returns .F. (false), the next Get object is searched that may receive input focus.
