Hi,

TRichView uses tags of inserted components itself.

If you need to associate additional data with the components you can create

your own components, for example

type

TMyButton = class (TButton)

private

FMyValue: Integer;

published

property MyValue: Integer read FFMyValue write FFMyValue;

end;

and use them instead of standard components.

You can add any number of properties of different types. All published

properties will be saved in RVF (do not forget to register this component:

RegisterClass(TMyButton)).

Focused items works only in TRichView (component or hyperlink can be

focused - it's shown with dotted rectangle around them), not in

TRichViewEdit.

In control's OnClick the Sender parameter is the clicked component itself.

Which additional information do you need?
