    Hallo Leute,

    ich habe meine Daten so vorliegen dass ich den Standard Vector - Vector - Konstruktor zum aufbauen einer Tabelle benutzen kann.
    nun bin ich vor dem Problem, dass meine Tabelle keinesfalls editierbar sein darf.
    wie kann ich den Konstruktor Vector Vector in ein eigenes Table Modell übernehmen und wie mache ich dann beim aufbauen meiner Tabelle dann den Aufruf zum füllen der Tabelle.

    Danke schonmal und Gruß
    Malte Roessner

    Hallo,
    nunja ich würde ungerne n eigenes Table Modell nur für nicht Editierbarkeit der Zeilen schreiben müssen. vielleicht gehts ja auch anders?....
    ich poste mal meinen Versuch eines eigenen TableModels, der allersings leider nicht funktioniert
    Über response.getArray im Konstruktor bekomme ich meinen Tabellen Inhalt entsprechend im Vector von Vectoren Format... daher würde ich eigentlich gerne den Konstruktor table = new JTable(Vector, Vector) wenn schon ein TableModell nötig sein sollte gerne beibehalten...

    wenn ich mit dem Modell arbeite bekomme ich eine leere Tabelle angezeigt...
    Leider!

    Danke an alle die mir bisher sehr weitergeholfen haben...
    Gruß Malte

    Hallo Malte,

    da Du ein eigenes TableModel nutzt, solltest Du diesem auch die beiden Vectoren übergeben:
    Code :
    1

    MeineTab model = new MeineTab(tableinhalt, spaltennamen);
    damit das funktioniert, musst Du natürlich einen solchen Konstruktor in Dein TableModel implementieren:
    Code :
    1
2
3

    public MyTableModel(Vector<Vector> data, Vector<String> columnNames) {
        super(data, columnNames);
    }
    und dann mit diesem model die Tabelle erstellen:
    Code :
    1

    JTable table = new JTable(model)

    MfG

    Hallo,
    danke erstmal...
    es klappt so weit die Editierbarkeit ist gesperrt.
    nun habe ich allerdings das Problem, dass ich sie nicht mehr mit anklicken und ok_Button auslesen kann (Zeilenweise), ich benötige jeweils das erste Feld aus meiner Tabellenzeile die ausgewählt worden ist. Welche Methode muss ich in Model implementieren, dass auch das wieder klappt, es klappte vor Einbindung des Models.. geht das überhaupt mit DefaultTableModel.
    Ich poste nochmal meinen abgeänderten Quelltext bei dem ich bei actionPerformed je das erste Feld aus der ausgewählten Tabellenzeile auswählen will.

    Danke und Gruß
    Euer
    Malte

    Hallo nochmal,
    gehe ich recht in der Annahme, dass ich
    public Object getValueAt(int row , int col) und
    public int getSelectedRow()
    in MeineTab erst überschreiben bzw mit neuem Leben füllen muss?
    wenn ja kann mir jemand mal ne Seite sagen wo ein Beispiel dazu ist?
    danke schonmal und Gruß
    Malte

    Hallo,

    mit getValueAt hast Du völlig recht. Hier ist mal ein kleines Beispiel, in dem eine Tabelle mit Daten gefüllt wird. Wenn Du nun eine Zelle anklickst und anschliessend den Button "auslesen" klickst, wird Dir der Inhalt der Zelle ausgegeben:

    Hallo,
    danke erstmal für die ausführliche Anwort mit dem Tablemodell.
    also meine Übergabe läuft ohne Modell (1) einwandfrei allerdings mit Modell (2) schmiert er schon beim Aufbauen der Tabelle mit folgender Fehlermeldung ab...
    wenn du vielleicht meinen Tippfehler oder sonstigen Tippfehler entdecken würdest wäre das phänomenal
    danke erstmal und Gruß
    Malte

    PS: gleiche Art aufzurufen läuft bei deiner Testklasse "TableModelSample"
    mit den Zeilen:
    Code :
    1
2
3
4
5
6
7
8
9
10

      // eigenes TableModel mit Daten-Vector und Spaltennamen instanzieren
        MyTableModel model = new MyTableModel(vData, colNames);
 
 
        // Tabelle mit eigenem TableModel erstellen
        
        final JTable table = new JTable(model);
        JScrollPane scrollpane = new JScrollPane(table);
        add(scrollpane).setBounds(10, 10, 250, 180);
        add(button).setBounds(10, 200, 120, 20);
    einwandfrei. ich weiss nicht was ich bei meinem Aufruf anders mache ...

    Exception occurred during event dispatching:
    java.lang.ArrayIndexOutOfBoundsException: 2 >= 2

    Ich denke, es wird daran liegen, wie Du den Datenvector erstellst:
    Code :
    1

    this.tableinhalt=response.getArray();

    Ich kenne ja Dein Response-Object nicht. Wenn ich nun also den Datenvector mit dummy-daten fülle, klappt das wunderbar...

    Hallo nochmal,
    das seltsame ist nur dass es ja klappt mit meinem MiniModel und mit dem Standard-Vector-Vector-Konstruktor von Table. Ich poste dir mal eben meine
    Response Klasse vielleicht findest ja was...
    response.getArray() gibt n Vector von Vectoren zurück wie es im Konstruktor von JTable gefordert ist
    aber nun der Code und Danke schon mal bis hierhin
