(FIELD

justification);
Field justification is only applied to static fields, a dynamic field will not
be justified. The default justification for a field is NO_JUSTIFICATION. The
field_just
() will return the current justification
value of the given field and the justification may be set by calling the
set_field_just
() function.
The following are the valid justifications for a field:
- NO_JUSTIFICATION
- No justification is to be applied to the field. In practice, this is the
same as JUSTIFY_LEFT.
- JUSTIFY_RIGHT
- The field will be right justified. That is, the end of each line will be
butted up against the right hand side of the field.
- JUSTIFY_LEFT
- The field will be left justified. That is, the start of each line will be
butted up against the left hand side of the field.
- JUSTIFY_CENTER
- The field will be centre justified, padding will be applied to either end
of the line to make the line centred in the field.
The functions will return one of the following error values:
E_OK
- The function was successful.
E_CURRENT
- The field specified is the currently active one on the form.
E_BAD_ARGUMENT
- A bad argument was passed to the function.
