TCustomUpDown.CreateParams Method

Initializes the window creation parameters for the up-down control.

Pascal
procedure CreateParams(var Params: TCreateParams); override;
C++
virtual __fastcall CreateParams(TCreateParams Params);

CreateParams is called automatically before the window for an up-down control is created. CreateParams calls the inherited method, then sets the Params parameter to reflect the values of the AlignButton, ArrowKeys, Orientation, Thousands, and Wrap properties.
