如何使用箭头按钮在 TableView 的编辑模式下遍历单元格

Question

我想使用箭头/enter键遍历 中的单元格，但是，如果我尝试在我的自定义EditCell类中实现它，它似乎不起作用。有没有办法做到这一点？我尝试过在 上使用侦听器，但它实际上并没有在实际单元格中启动焦点。TableViewTextField

这是我的代码：

测试人员.java

package tester;

import javafx.application.Application;

import javafx.scene.Scene;

import javafx.scene.control.TableCell;

import javafx.scene.control.TableColumn;

import javafx.scene.control.TableRow;

import javafx.scene.control.TableView;

import javafx.scene.layout.HBox;

import javafx.stage.Stage;

import javafx.util.Callback;

public class Tester extends Application

{

    @Override

    public void start(Stage primaryStage)

    {

        TableView<LineItem> table = new TableView<>();

        Callback<TableColumn<LineItem, String>, TableCell<LineItem, String>> textFactoryEditable = (TableColumn<LineItem, String> p) -> new EditableTextCell();

        TableColumn<LineItem, String> column1 = new TableColumn<>("Test1");

        column1.setCellValueFactory(cellData -> cellData.getValue().getString1Property());

        column1.setEditable(true);

        column1.setCellFactory(textFactoryEditable);

        table.getColumns().add(column1);

        TableColumn<LineItem, String> column2 = new TableColumn<>("Test2");

        column2.setCellValueFactory(cellData -> cellData.getValue().getString2Property());

        column2.setEditable(true);

        column2.setCellFactory(textFactoryEditable);

        table.getColumns().add(column2);

        table.getItems().add(new LineItem());

        table.getItems().add(new LineItem());

        table.getItems().add(new LineItem());

        table.setPrefWidth(500);

        HBox root = new HBox();

        root.getChildren().addAll(table);

        Scene scene = new Scene(root, 500, 500);

        primaryStage.setTitle("Hello World!");

        primaryStage.setScene(scene);

        primaryStage.show();

    }

    /**

     * @param args the command line arguments

     */

    public static void main(String[] args)

    {

        launch(args);

    }

}

行选择模式尽管我的评论，但看起来您并不需要为此启用单元格选择。从CheckBoxTableCell的实现中汲取灵感，您的自定义应该采用某种形式的回调来获取模型属性;它还可能需要一个&nbsp;StringConverter，允许您使用不仅仅包含 s 的 。下面是一个示例：TableCellTableCellStringimport java.util.Objects;import java.util.function.IntFunction;import javafx.beans.binding.Bindings;import javafx.beans.property.ObjectProperty;import javafx.beans.property.Property;import javafx.beans.property.SimpleObjectProperty;import javafx.scene.control.TableCell;import javafx.scene.control.TableColumn;import javafx.scene.control.TableView.TableViewFocusModel;import javafx.scene.control.TextField;import javafx.scene.input.KeyEvent;import javafx.util.Callback;import javafx.util.StringConverter;import javafx.util.converter.DefaultStringConverter;public class CustomTableCell<S, T> extends TableCell<S, T> {&nbsp; &nbsp; public static <S> Callback<TableColumn<S, String>, TableCell<S, String>> forTableColumn(&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; IntFunction<Property<String>> extractor) {&nbsp; &nbsp; &nbsp; &nbsp; return forTableColumn(extractor, new DefaultStringConverter());&nbsp; &nbsp; }&nbsp; &nbsp; public static <S, T> Callback<TableColumn<S, T>, TableCell<S, T>> forTableColumn(&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; IntFunction<Property<T>> extractor, StringConverter<T> converter) {&nbsp; &nbsp; &nbsp; &nbsp; Objects.requireNonNull(extractor);&nbsp; &nbsp; &nbsp; &nbsp; Objects.requireNonNull(converter);&nbsp; &nbsp; &nbsp; &nbsp; return column -> new CustomTableCell<>(extractor, converter);&nbsp; &nbsp; }&nbsp; &nbsp; private final ObjectProperty<IntFunction<Property<T>>> extractor = new SimpleObjectProperty<>(this, "extractor");&nbsp; &nbsp; public final void setExtractor(IntFunction<Property<T>> callback) { extractor.set(callback); }&nbsp; &nbsp; public final IntFunction<Property<T>> getExtractor() { return extractor.get(); }&nbsp; &nbsp; public final ObjectProperty<IntFunction<Property<T>>> extractorProperty() { return extractor; }&nbsp; &nbsp; private final ObjectProperty<StringConverter<T>> converter = new SimpleObjectProperty<>(this, "converter");&nbsp; &nbsp; public final void setConverter(StringConverter<T> converter) { this.converter.set(converter); }&nbsp; &nbsp; public final StringConverter<T> getConverter() { return converter.get(); }&nbsp; &nbsp; public final ObjectProperty<StringConverter<T>> converterProperty() { return converter; }&nbsp; &nbsp; private Property<T> property;&nbsp; &nbsp; private TextField textField;&nbsp; &nbsp; public CustomTableCell(IntFunction<Property<T>> extractor, StringConverter<T> converter) {&nbsp; &nbsp; &nbsp; &nbsp; setExtractor(extractor);&nbsp; &nbsp; &nbsp; &nbsp; setConverter(converter);&nbsp; &nbsp; &nbsp; &nbsp; // Assumes this TableCell will never become part of a different TableView&nbsp; &nbsp; &nbsp; &nbsp; // after the first one.

Answer 2

多亏了Slaw，才想通了。首先启用单元格选择，table.getSelectionModel().setCellSelectionEnabled(true);然后在 EditableTextCell.java类中：&nbsp; &nbsp; &nbsp; &nbsp; this.focusedProperty().addListener((ObservableValue<? extends Boolean> o, Boolean oldValue, Boolean newValue) ->&nbsp; &nbsp; &nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if (newValue)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; textField.requestFocus();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; });&nbsp; &nbsp; &nbsp; &nbsp; textField.focusedProperty().addListener((ObservableValue<? extends Boolean> o, Boolean oldValue, Boolean newValue) ->&nbsp; &nbsp; &nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if (newValue)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; getTableView().getFocusModel().focus(getTableRow().getIndex(), getTableColumn());&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; textField.setOnKeyPressed((KeyEvent ke) ->&nbsp; &nbsp; &nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; switch (ke.getCode())&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; case DOWN:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; getTableView().getFocusModel().focusBelowCell();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ke.consume();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; break;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; case ENTER:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; getTableView().getFocusModel().focusBelowCell();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ke.consume();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; break;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; case UP:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; getTableView().getFocusModel().focusAboveCell();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ke.consume();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; break;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; case RIGHT:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; getTableView().getFocusModel().focusRightCell();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ke.consume();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; break;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; case LEFT:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; getTableView().getFocusModel().focusLeftCell();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ke.consume();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; break;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; default:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; break;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; });
