Provides the underlying implementation for the GetDisplayWidth method.

Pascal
function ImplGetDisplayWidth: Integer; override;
C++
virtual __fastcall int ImplGetDisplayWidth();
Description

GetDisplayWidth calls ImplGetDisplayWidth to obtain the width (number of characters) to use for an HTML control that displays the value of this adapter field (in server-side script, the value of the DisplayWidth property). 

ImplGetDisplayWidth calls FindField to access the associated field component and returns the value of its DisplayWidth property. If FindField returns nil (Delphi) or NULL (C++), ImplGetDisplayWidth returns –1, indicating that the default display width is undetermined.
