[D7] PropertyEditor für TCollection durch eigenen ersetzen.

[LoCrux]

Hallo @All (bin neu hier) und hab gleich ne Frage.

Ich schreibe seit geraumer Zeit an ein paar Komponenten rum. Da ich für eine Firma arbeite, die Schwerlasttransporter (genauer gesagt sog. SSC - Ship-Section-Carrier so ab 300t Last aufwärts) herstellt, will ich die Transporter als Delphi-Komponenten schreiben.

Für Interessierte : TITAN-Elevating Transporter

Pi Mal Daumen aufbau der Struktur.....

1.) TArea [Zeichenfläche abgeleitet von TPaintBox32 des Graphics32 Package] u.a. mit PROPERTY TPoleItems (TCollection) hält die u.a. die Komponente TPole (TComponent).

2.) TPole(TComponent) [ist für die Steuerung der einzelnen Achsen eines Transporters / Transporterverbandes zuständig]
und hält u.a. die PROPERTY TTransporterItems (TCollection) welche die einzelnen TTransporter (TComponent) hält...

3.) ..um es kurz zu halten, hat jeder Transporter wieder eine Collection die die einzelen Achsen hält.

Das ganze sieht dann in der IDE so aus (hier nur ein Transporter dargestellt):

Als fertiges Proggi (hier nur ein Test Projekt - Darstellung Finit [Drehmomente]):

Delphi-Quellcode:

UNIT TTransporters;

NACH DER "KURZEN" EINFÜHRUNG NUN ZU MEINEM EIGENTLICHEN PROBLEM.

Ich bekomme es nicht gebacken (und hab auch echt keinem richtigen Plan) wie ich den Property Editor für die CollectionItems
mit einem eigenen ersetze. Jedes (oder fast alle) Tutorial(s) beschreibt(beschreiben) nur die Standard PropertyEditoren (für z.B. TStringProperty, TIntegerProperty, etc..). Doch da ich vermutlich einen PopteryEditor abgeleitet von TClassProperty benötige wollte ich fragen, ob mir da jemand weiterhelfen kann). Hat einer schonmal einen Property bzw. Component Editor für komplexere Componenten geschrieben?
Ich hab echt keinem Plan wie ich aus dem Designtime Package auf die einzelenen Eigenschaften meiner Items zugreifen kann.

Wäre über ne Hilfestellung echt erfreut und schon Danke im voraus.
