如何将ComboBoxTableCell放在TableView中？

问题描述

我想把一个ComboBox放在表格单元格中，但我不能。代码是下一个：

I'm trying to put a ComboBox in a table cell, but I can't. the code is the next:

private void cargaTablaDesglose() {
    TableColumn<Map, String> column1 = new TableColumn<>(Desglose1);
    TableColumn<Map, String> column2 = new TableColumn<>(Desglose2);
    TableColumn<Map, String> column3 = new TableColumn<>(Desglose3);

    column1.setCellValueFactory(new MapValueFactory(Desglose1));
    column1.setMaxWidth(0);
    column2.setCellValueFactory(new ComboBoxTableCell.forTableColumn(null));
    column2.setPrefWidth(150);
    column3.setCellValueFactory(new MapValueFactory(Desglose3));
    column3.setPrefWidth(250);

    if (CUOD.modifyData()) {
        column2.setOnEditCommit((TableColumn.CellEditEvent<Map, String> t) -> {
            actualizaObra(t.getRowValue(), t.getNewValue());
        });
            }

    tablaDesglose.getItems().clear();
    tablaDesglose.setEditable(true);
    tablaDesglose.getSelectionModel().setSelectionMode(SelectionMode.MULTIPLE);
    tablaDesglose.getSelectionModel().setCellSelectionEnabled(false);
    tablaDesglose.getColumns().clear();
    tablaDesglose.getColumns().addAll(column1, column2, column3);

    Callback<TableColumn<Map, String>, TableCell<Map, String>> cellFactoryMap
            = CUCF.getFactoryMap();
    column1.setCellFactory(cellFactoryMap);
    column2.setCellFactory(cellFactoryMap);
    column3.setCellFactory(cellFactoryMap);
}

它表示找不到ComboBoxTableCell的TableColumn方法

It says that can't found forTableColumn method of ComboBoxTableCell

推荐答案

问题的部分是你试图将单元格工厂设置为 TableColumn 。试试这个：

The part of the problem is that you're trying to set cell factory into cell value factory field of TableColumn. Try this instead:

ObservableList<String> cbValues = FXCollections.observableArrayList("1", "2", "3");

TableColumn<Map, String> column2 = new TableColumn<>(Desglose2);
column2.setCellFactory(ComboBoxTableCell.forTableColumn(new DefaultStringConverter(), cbValues));
