Description

The SpinEdit component is the combination of single-line edit box and changing value buttons.

Working with the Component

The component enables the user to display and edit different data (text and numeric). As opposed to the other editors (FloatEdit, IntegerEdit), which change the value with the required step, in the SpinEdit component the step and the output value are defined by the user algorithm. This algorithm must be implemented in the OnSpinDown and OnSpinUp event handlers. In the specified handlers the output value must be specified in the Text component property.
