Decrease the current edit value.
<oSpinEdit>:SpinDown(<uSpin>) Æ lSuccess
|<uSpin>||The value by which the edit value should to be decreased. Supported data types are all numeric values (e.g., Short, Integer, DWord, Float etc.).|
|lSuccess||A logical value which defines whether the current edit value could be decreased.|
|TRUE||The edit value was decreased.|
|FALSE||The edit value could not be decreased.|
bSpinEdit:SpinDown() decreased the current edit value of the control. If a FieldSpec is provided which defines a minimum value and decreasing the edit value yields a smaller value than the defined minimum value, then the edit value is restricted to the minimum value of the FieldSpec.
