When creating components you may want to know when the user changed the font or text. This can be quite easily done using the CM_FONTCHANGED and CM_TEXTCHANGED messages.

TComponent1 = class(TComponent)
…
private
…
procedure CMFontChanged(var Message: TMessage); message CM_FONTCHANGED;
procedure CMTextChanged(var Message: TMessage); message CM_TEXTCHANGED;
…
procedure TComponent1.CMTextChanged(var Message:TMessage);
begin
…
end;
procedure TComponent1.CMFontChanged(var Message:TMessage);
begin
…
end;
