VALUEMIN attribute

The VALUEMIN attribute defines a lower limit of values displayed in widgets (such as progress bars).

Syntax

VALUEMIN = integer
  1. integer is a integer literal.

Usage

This attribute is typically used to define the lower limit in PROGRESSBAR, SPINEDIT and SLIDER fields.

Default values for VALUEMIN/VALUEMAX depend on the type of the widget:
  • For a PROGRESSBAR, the default is VALUEMIN=0, VALUEMAX=100.
  • For a SLIDER, the default is VALUEMIN=0, VALUEMAX=5.
  • For a SPINEDIT, there is no default.

This attribute is not used by the runtime system to validate the field. Use the INCLUDE attribute to control value boundaries.

Important:

For maximum security, when the data is stored in a database, define a CHECK constraint on the SQL column corresponding to the field, in order to allow only values matching the VALUEMIN / VALUEMAX attributes, when an INSERT or UPDATE statement is executed.

Example

SLIDER s01 = FORMONLY.slider01,
             VALUEMIN=0,
             VALUEMAX=500;
