Hallo,
ich habe mal ein wenig mit den wxDataViewList Klassen usw. herum gespielt.
Hat unter Linux (wxGTK/Mac PPC) auch ganz gut funktioniert.
Nun ist das Ganze aber unter Mac OS X (Leopard) so ziemlich unsauber in der Darstellung und die Bedienung klappt auch nicht.
Wer hat denn damit schonmal zu tun gehabt und kennt evtl. andere Lösungswege
Daten in (für den User in gleicher Weise) einer Tabelle darzustellen ?
Danke
Lothar
Hier der Code eines Datenmodells und des Formulars. Der Code rund um UAP_REQUEST ist speziell aus meinem Framework um die Datenbankverbindung bereitzustellen:
// Generated class for FormularID = 2
class Formulare : public wxDataViewListModel {
public:
Formulare();
virtual ~Formulare();
virtual bool InitModel();
virtual unsigned int GetNumberOfRows();
virtual unsigned int GetNumberOfCols();
virtual wxString GetColType( unsigned int col );
virtual void GetValue( wxVariant &variant, unsigned int col, unsigned int row );
virtual bool SetValue( wxVariant &value, unsigned int col, unsigned int row );
