Detailed Description

DERIVED CLASS FOR UPDOWN CONTROLS.

% Provides the functionality of the Windows common updown control. An up-down control is a pair of arrow buttons that the user can click to increment or decrement a value, such as a scroll position or a number displayed in a companion control. The value associated with an up-down control is called its current position. An up-down control is most often used with a companion control, which is called a buddy window.
