Komponentenentwicklung - Zwei DataSourcen im Objektinspector

[Christian Seehase]

Moin Till,

nur mal so als Idee:
Die beiden Properties in der Custom-Klasse protected deklarieren, und erst in der abgeleiteten Klasse in published einbauen, also so:

Delphi-Quellcode:

type
  TCustomDBLookupLabel = Class( TCustomLabel )
  protected
   Property DataSource: TDataSource Read GetDataSource Write SetDataSource;
   Property DataFieldName: WideString Read FDataFieldName Write SetDataFieldName;
  end;

  TDBUnitLookupLabel = Class( TCustomDBLookupLabel )
  published
    property DataSource;
    property DataFieldName;
    Property QuantityFieldName: WideString Read FQuantityFieldName Write SetQuantityFieldName;
    Property QuantityDataSource: TDataSource Read GetQuantityDataSource Write SetQuantityDataSource;
  end;
