Description
TCustomUpDown is the base type for up-down size controls such as TUpDown.
Use TCustomUpDown as a base class when defining up-down controls such as the arrows that appear in a spin box. Up-down controls allow users to change the size of a numerical value by clicking on arrow buttons. TCustomUpDown introduces several properties, events, and methods to associate an up-down control with another control in a form and to communicate the size changes specified by the user.
Do not create instances of TCustomUpDown. To put an up-down control in a form, use TUpDown.
