Indicates whether a component does not appear directly in the form designer.
function IsComponentHidden(Component: TComponent): Boolean;
Call IsComponentHidden to determine whether the component specified by the Component parameter appears directly in the form designer. When IsComponentHidden returns true, the component does not appear as an icon or control. For example, menu items and field components are hidden components, and can only be accessed through a parent componentís editor (the menu designer or fields editor). Hidden components are registered using the RegisterNoIcon procedure.
