Hier ist die aktuelle Variante der Komponente. Jetzt klappt es auch mit den Zuweisungen. Der Fehler war, dass ich TSubPosition nur als (lpTop, lpBottom, lpLeft, lpRight) deklariert hatte. Wenn ich dann die Subkomponente (Label) aber z.B. als Client eingestellt hatte, gab es diesen ominösen Fehler beim Laden. Jetzt, nachdem ich TSubPosition als (lpNone, lpTop, lpBottom, lpLeft, lpRight, lpClient, lpCustom) deklariert habe, klappt es.
Was ich jetzt noch gern machen würde, wäre eine Abkürzung, um ein Bild (png,bmp,gif,...) über den ObjectInspector als Property bereitstellen zu können. Aber ich scheitere an der korrekten Zuweisung ![]()
