选择SET行

Question

我试图设置从JTable中选择的行，我得到并比较从我的数据库收到的所有数据，然后在比较数据是否存在时，它必须设置该行被选中。

我已尝试过多个函数，例如setSelectionModel或setSelectionInterval，并且这些函数都没有选中具有必须选择的值的行。

有什么建议吗？

下面是一些代码....不确定它会有什么帮助...但它是我在网上看到的...没有选择我想要的行... leerTripulantesVuelo带回了一系列的Tripulante这就是我的意思在列表中选择THAT Tripulante。

ModeloTablaTripulantes tablaPil = new ModeloTablaTripulantes();
tablaPilotos.setModel(tablaPil);
tablaPilotos.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);

ArrayList<Tripulante> trip = new ArrayList();

    String tipoPersona = "t";
    String numVuelo = numeroVueloListaTripulantes.getText();

    try {
        trip = Aerolinea.leerTripulantesVuelo(numVuelo);
        for (Tripulante t: trip){
            for(int i =0; i<tablaPil.getRowCount();i++){
                if (tablaPil.getValueAt(i, 0).equals(t.getCedula())){
                    tablaPilotos.getSelectionModel().setSelectionInterval(i, i);
                }
            }

        }
    } catch (BDException ex) {
        ex.printStackTrace();
    }

Answer 1

以下是选择表格中第二行的完整示例。 我使用NetBeans所以只是不关心ui的代码。 jButton1ActionPerformed中的代码包含jTable1.getSelectionModel().setSelectionInterval(row, row)，它完全符合我的预期 - 选择该行 你确定你的程序运行到setSelectionInterval()吗？也许字符串最后包含空格。调试应该有助于找到答案。

package tripulante;
