No, that's still too early. Overload .Loaded instead.
Cheers,
Ignacio

But remember that Loaded is not called when the component is created at
runtime (not loaded from stream). If you need certain properties to be set
before you do something, why don't you simply write setter procedures for
that properties?

My component has a registry component that reads and writes to the
registry as
one of its properties. Until the registry component is loaded I can't use
it to
read in the properties.

I see. Probably you do not plan to create the component at runtime. But if
you do so, something like this might help (of course I do not know how
exactly your components work):
procedure TMyComponent.Loaded;
begin
inherited;
if FRegistryComponent <> nil then
FRegistryComponent.Load(Self); // load values from registry after all
components (including FRegistryComponent) are loaded
end;
procedure TMyComponent.SetRegistryComponent(Value: TMyRegistryComponent);
begin
if (FRegistryComponent <> Value) then begin
FRegistryComponent := Value;
if (FRegistryComponent <> nil) and not (csLoading in ComponentState)
then
FRegistryComponent.Load(Self); // load values from registry if
component is created at runtime and/or RegistryComponent property was
changed
end;
end;
