java - 如何填充 ComboBoxTableCell 下拉列表

Question

我有一个 cellFactory，它在 TableView 列中创建可编辑的 ComboBoxTableCell:

Callback<TableColumn<Map, String>, TableCell<Map, String>>
            cellFactoryForComboBox = (TableColumn<Map, String> p) -> {
                ComboBoxTableCell<Map, String> cell = new ComboBoxTableCell<>();
                cell.setComboBoxEditable(true);
                return cell;
        };

Col1.setCellFactory(cellFactoryForComboBox);
Col2.setCellFactory(cellFactoryForComboBox);

如何使用以下值填充每列的下拉列表

ObservableList<String> List1
ObservableList<String> List2

如何正确执行此操作？

Answer 1

为每列创建单独的cellFactory并将ObservableList传递给the constructor of ComboBoxTableCell :

Col1.setCellFactory((TableColumn<Map, String> p) -> {
                ComboBoxTableCell<Map, String> cell = new ComboBoxTableCell<>(List1);
                cell.setComboBoxEditable(true);
                return cell;
        });
Col2.setCellFactory((TableColumn<Map, String> p) -> {
                ComboBoxTableCell<Map, String> cell = new ComboBoxTableCell<>(List2);
                cell.setComboBoxEditable(true);
                return cell;
        });
