在我的 Java 桌面应用程序中，我有一个 TableView，我希望在其中有一列带有 CheckBoxes。
我确实找到了在哪里完成此操作 http://www.jonathangiles.net/javafx/2.0/CellFactories/，但由于无法下载，而且我不知道 Jonathan Giles 多久会回复我的电子邮件，所以我想我会问...
如何将 CheckBox 放入 TableView 的单元格中？
【问题讨论】：
标签： java checkbox tableview tablecell javafx-2
使用javafx.scene.control.cell.CheckBoxTableCell<S,T>，工作就完成了！
ObservableList< TableColumn< RSSReader, ? >> columns =
_rssStreamsView.getColumns();
[...]
TableColumn< RSSReader, Boolean > loadedColumn = new TableColumn<>( "Loaded" );
loadedColumn.setCellValueFactory(
new Callback<CellDataFeatures<RSSReader,Boolean>,ObservableValue<Boolean>>(){
@Override public
ObservableValue<Boolean> call( CellDataFeatures<RSSReader,Boolean> p ){
return p.getValue().getCompleted(); }});
loadedColumn.setCellFactory(
new Callback<TableColumn<RSSReader,Boolean>,TableCell<RSSReader,Boolean>>(){
@Override public
TableCell<RSSReader,Boolean> call( TableColumn<RSSReader,Boolean> p ){
return new CheckBoxTableCell<>(); }});
[...]
columns.add( loadedColumn );
更新：使用Java 8 lambda expressions的相同代码
ObservableList< TableColumn< RSSReader, ? >> columns =
_rssStreamsView.getColumns();
[...]
TableColumn< RSSReader, Boolean > loadedColumn = new TableColumn<>( "Loaded" );
loadedColumn.setCellValueFactory( f -> f.getValue().getCompleted());
loadedColumn.setCellFactory( tc -> new CheckBoxTableCell<>());
[...]
columns.add( loadedColumn );
行数除以二！ (16 ==> 8)
更新：使用Java 10 "var" contextual word的相同代码
var columns = _rssStreamsView.getColumns();
[...]
var loadedColumn = new TableColumn<RSSReader, Boolean>( "Loaded" );
loadedColumn.setCellValueFactory( f -> f.getValue().getCompleted());
loadedColumn.setCellFactory( tc -> new CheckBoxTableCell<>());
[...]
columns.add( loadedColumn );

setEditable(true); 也无济于事。
setEditable 才能编辑表格。列可能是可编辑的，并且基础模型必须设置为可编辑。这是另一个问题，另一个帖子。请创建一篇新帖子，其中包含有关可编辑 JavaFX 表的完整问题。
您需要在 TableColumn 上设置一个 CellFactory。
例如：
Callback<TableColumn<TableData, Boolean>, TableCell<TableData, Boolean>> booleanCellFactory =
new Callback<TableColumn<TableData, Boolean>, TableCell<TableData, Boolean>>() {
@Override
public TableCell<TableData, Boolean> call(TableColumn<TableData, Boolean> p) {
return new BooleanCell();
}
};
active.setCellValueFactory(new PropertyValueFactory<TableData,Boolean>("active"));
active.setCellFactory(booleanCellFactory);
class BooleanCell extends TableCell<TableData, Boolean> {
private CheckBox checkBox;
public BooleanCell() {
checkBox = new CheckBox();
checkBox.setDisable(true);
checkBox.selectedProperty().addListener(new ChangeListener<Boolean> () {
public void changed(ObservableValue<? extends Boolean> observable, Boolean oldValue, Boolean newValue) {
if(isEditing())
commitEdit(newValue == null ? false : newValue);
}
});
this.setGraphic(checkBox);
this.setContentDisplay(ContentDisplay.GRAPHIC_ONLY);
this.setEditable(true);
}
@Override
public void startEdit() {
super.startEdit();
if (isEmpty()) {
return;
}
checkBox.setDisable(false);
checkBox.requestFocus();
}
@Override
public void cancelEdit() {
super.cancelEdit();
checkBox.setDisable(true);
}
public void commitEdit(Boolean value) {
super.commitEdit(value);
checkBox.setDisable(true);
}
@Override
public void updateItem(Boolean item, boolean empty) {
super.updateItem(item, empty);
if (!isEmpty()) {
checkBox.setSelected(item);
}
}
}
【讨论】：
TableColumn select = new TableColumn("CheckBox");
select.setMinWidth(200);
select.setCellValueFactory(new Callback<TableColumn.CellDataFeatures<Person, CheckBox>, ObservableValue<CheckBox>>() {
@Override
public ObservableValue<CheckBox> call(
TableColumn.CellDataFeatures<Person, CheckBox> arg0) {
Person user = arg0.getValue();
CheckBox checkBox = new CheckBox();
checkBox.selectedProperty().setValue(user.isSelected());
checkBox.selectedProperty().addListener(new ChangeListener<Boolean>() {
public void changed(ObservableValue<? extends Boolean> ov,
Boolean old_val, Boolean new_val) {
user.setSelected(new_val);
}
});
return new SimpleObjectProperty<CheckBox>(checkBox);
}
});
table.getColumns().addAll( select);
【讨论】：
小而简单。
row.setCellValueFactory(c -> new SimpleBooleanProperty(c.getValue().getIsDefault()));
row.setCellFactory(tc -> new CheckBoxTableCell<>());【讨论】：
最简单的解决方案可能是在 FXML 中进行：
首先创建下面的类：
public class CheckBoxCellFactory<S, T>
implements Callback<TableColumn<S, T>, TableCell<S, T>> {
@Override public TableCell<S, T> call(TableColumn<S, T> p) {
return new CheckBoxTableCell<>();
}
}
然后在您的 FXML 中包含一个单元工厂：
<TableColumn text="Select" fx:id="selectColumn" >
<cellFactory>
<CheckBoxCellFactory/>
</cellFactory>
</TableColumn>
你还需要在FXML中添加一个import，比如<?import com.assylias.factories.*?>
奖励：您可以使工厂更加可定制，例如，通过向CheckBoxCellFactory 类添加字段来确定复选框应该出现的位置，例如：
private Pos alignment = Pos.CENTER;
public Pos getAlignment() { return alignment; }
public void setAlignment(Pos alignment) { this.alignment = alignment; }
还有 FXML：
<cellFactory>
<CheckBoxCellFactory alignment="BOTTOM_RIGHT"/>
</cellFactory>
【讨论】：
有一种非常简单的方法可以做到这一点，您不需要使用 SimpleBooleanProperty 或其他方式修改模型类，只需按照以下步骤操作即可：
1 - 假设您有一个带有 isUnemployed 方法的“Person”对象：
public class Person {
private String name;
private Boolean unemployed;
public String getName(){return this.name;}
public void setName(String name){this.name = name;}
public Boolean isUnemployed(){return this.unemployed;}
public void setUnemployed(Boolean unemployed){this.unemployed = unemployed;}
}
2 - 创建回调类
import javafx.beans.property.SimpleObjectProperty;
import javafx.beans.value.ObservableValue;
import javafx.scene.control.CheckBox;
import javafx.scene.control.TableColumn;
import javafx.util.Callback;
public class PersonUnemployedValueFactory implements Callback<TableColumn.CellDataFeatures<Person, CheckBox>, ObservableValue<CheckBox>> {
@Override
public ObservableValue<CheckBox> call(TableColumn.CellDataFeatures<Person, CheckBox> param) {
Person person = param.getValue();
CheckBox checkBox = new CheckBox();
checkBox.selectedProperty().setValue(person.isUnemployed());
checkBox.selectedProperty().addListener((ov, old_val, new_val) -> {
person.setUnemployed(new_val);
});
return new SimpleObjectProperty<>(checkBox);
}
}
3 - 将回调绑定到表格列
如果您使用 FXML，请将回调类放在您的列中：
<TableView fx:id="personList" prefHeight="200.0" prefWidth="200.0">
<columns>
<TableColumn prefWidth="196.0" text="Unemployed">
<cellValueFactory>
<PersonUnemployedValueFactory/> <!--This is how the magic happens-->
</cellValueFactory>
</TableColumn>
...
</columns>
</TableView>
别忘了在你的 FXML 中导入类：
<?import org.yourcompany.yourapp.util.PersonUnemployedValueFactory?>
如果没有 FXML，请这样做：
TableColumn<Person, CheckBox> column = (TableColumn<Person, CheckBox>) personTable.getColumns().get(0);
column.setCellValueFactory(new PersonUnemployedValueFactory());
4 - 就是这样
一切都应该按预期工作，当您单击复选框时将值设置为支持 bean，并且当您在表中加载项目列表时正确设置复选框值。
【讨论】：
这最终对我有用（请注意，我的模型中的对象是Candidate，复选框确定它们是否被排除在外，因此isExcluded()）：
tableColumnCandidateExcluded.setCellValueFactory(
c -> {
Candidate candidate = c.getValue();
CheckBox checkBox = new CheckBox();
checkBox.selectedProperty().setValue(candidate.isExcluded());
checkBox
.selectedProperty()
.addListener((ov, old_val, new_val) -> candidate.setExcluded(new_val));
return new SimpleObjectProperty(checkBox);
});
【讨论】：
为了将 EDITABLE 复选框链接到模型，最简单的解决方案是：
假设您有一个 Person 模型类，其中包含两个字段，一个“名称”字符串和一个“选定”布尔值：
public class Person {
private final SimpleBooleanProperty selected;
private final SimpleStringProperty name;
public Person(String name) {
this.selected = new SimpleBooleanProperty(false);
this.name = new SimpleStringProperty(name);
}
public boolean isSelected() {
return selected.get();
}
public SimpleBooleanProperty selectedProperty() {
return selected;
}
public void setSelected(boolean selected) {
this.selected.set(selected);
}
public String getName() {
return name.get();
}
public SimpleStringProperty nameProperty() {
return name;
}
public void setName(String name) {
this.name.set(name);
}
}
您在控制器中所要做的就是：
@FXML private TableColumn<Person, Boolean> checkBoxCol;
@FXML private TableColumn<Person, String> nameCol;
@Override
public void initialize(URL location, ResourceBundle resources) {
checkBoxCol.setCellFactory(
CheckBoxTableCell.forTableColumn(checkBoxCol)
);
checkBoxCol.setCellValueFactory(
new PropertyValueFactory<>("selected")
);
nameCol.setCellValueFactory(
new PropertyValueFactory<>("name")
);
}

受先前答案的启发，我认为这是最短的版本。
checkBoxColumn.setCellValueFactory(c -> {
c.getValue().booleanProperty().addListener((ch, o, n) -> {
// do something
});
return c.getValue().booleanProperty();
});
checkBoxColumn.setCellFactory(CheckBoxTableCell.forTableColumn(checkBoxColumn));
【讨论】：
这就是方法
tbcSingleton.setCellValueFactory(data -> data.getValue().singletonProperty());
tbcSingleton.setCellFactory( param -> {
return new TableCell<FXMLController, Boolean>(){
{
setAlignment(Pos.CENTER);
}
protected void updateItem(Boolean item, boolean empty){
if(!empty && item!=null) {
CheckBox cb = new CheckBox();
cb.setSelected(item);
cb.setFocusTraversable(false);
cb.selectedProperty().addListener((obs,old,niu)->listaFXMLController.get(getIndex()).setSingleton(niu));
setGraphic(cb);
}else
setGraphic(null);
}
};
});
cb.setFocusTraversable(false) 是防止获得焦点所必需的 坚持下去。
setGraphic(null) 用于在删除项目后或源列表更改时擦除遗留的任何内容
这是另一个带有 ToggleGroup 和 ToggleButtons 的按钮
tbcTipoControlador.setCellValueFactory(data -> data.getValue().controllerTypeProperty());
tbcTipoControlador.setCellFactory( param -> {
return new TableCell<FXMLController, ControllerType>() {
{
setAlignment(Pos.CENTER);
}
protected void updateItem(ControllerType item, boolean empty){
if(!empty && item!=null) {
ToggleButton tbModal = new ToggleButton("Modal");
tbModal.selectedProperty().addListener((obs,old,niu)->{
if(niu)
listaFXMLController.get(getIndex()).setControllerType(ControllerType.MODAL);
});
tbModal.setSelected(item.equals(ControllerType.MODAL));
ToggleButton tbPlain = new ToggleButton("Plain");
tbPlain.selectedProperty().addListener((obs,old,niu)->{
if(niu)
listaFXMLController.get(getIndex()).setControllerType(ControllerType.PLAIN);
});
tbPlain.setSelected(item.equals(ControllerType.PLAIN));
ToggleButton tbApplication= new ToggleButton("Application");
tbApplication.selectedProperty().addListener((obs,old,niu)->{
if(niu)
listaFXMLController.get(getIndex()).setControllerType(ControllerType.APPLICATION);
});
tbApplication.setSelected(item.equals(ControllerType.APPLICATION));
ToggleGroup gp = new ToggleGroup();
tbModal.setFocusTraversable(false);
tbPlain.setFocusTraversable(false);
tbApplication.setFocusTraversable(false);
tbModal.setPrefWidth(120);
tbPlain.setPrefWidth(120);
tbApplication.setPrefWidth(120);
gp.getToggles().addAll(tbModal,tbPlain,tbApplication);
HBox hb = new HBox();
hb.setAlignment(Pos.CENTER);
hb.getChildren().addAll(tbModal,tbPlain,tbApplication);
setGraphic(hb);
}else
setGraphic(null);
}
};
});
我做了一些测试，内存消耗和使用ComboBoxTableCell基本一样

对我来说，使用这个解决方案：
Callback<TableColumn, TableCell> checkboxCellFactory = new Callback<TableColumn, TableCell>() {
@Override
public TableCell call(TableColumn p) {
return new CheckboxCell();
}
};
TableColumn selectColumn = (TableColumn) tbvDatos.getColumns().get(1);
selectColumn.setCellValueFactory(new PropertyValueFactory("selected"));
selectColumn.setCellFactory(checkboxCellFactory);
和tableCell：
public class CheckboxCell extends TableCell<RowData, Boolean> {
CheckBox checkbox;
@Override
protected void updateItem(Boolean arg0, boolean arg1) {
super.updateItem(arg0, arg1);
paintCell();
}
private void paintCell() {
if (checkbox == null) {
checkbox = new CheckBox();
checkbox.selectedProperty().addListener(new ChangeListener<Boolean>() {
@Override
public void changed(ObservableValue<? extends Boolean> ov,
Boolean old_val, Boolean new_val) {
setItem(new_val);
((RowData)getTableView().getItems().get(getTableRow().getIndex())).setSelected(new_val);
}
});
}
checkbox.setSelected(getValue());
setText(null);
setGraphic(checkbox);
}
private Boolean getValue() {
return getItem() == null ? false : getItem();
}
}
