TCustomFloatSpinEdit.ValueEmpty property

Declaration

property ValueEmpty: Boolean read FValueEmpty write SetValueEmpty default False;

Description

ValueEmpty is a Boolean property which indicates whether or not an explicit numeric value has been assigned to the Value property. ValueEmpty is updated in the TextChanged method when a new value in Text is handled for the control. When set to True, an explicit value has not been assigned.

The default value for the property is False.

Changing the value for the property causes the UpdateControl method to be called. This re-applies the range limits in MinValue and MaxValue (when assigned and needed) and posts the update the widgetset class.
