setOnEditCommit JavaFX 后禁用 TableCell
disable TableCell after setOnEditCommit JavaFX
我创建了一个 editable table，它有一个特定的列 (quantityColumn)，当 setOnEditCommit 完成时，只有该列的单元格应该被禁用，而不是 editable。所以换句话说，他们只能进入一次。该程序有一个添加行按钮，可以将新行添加到 table 并且 setOnEditCommit 使用每列中每个单元格的新值更新数据库。
一个 示例 我的代码的样子：
public class TableViewController implements Initializable {
/**

我试过在这里寻找答案。这也是one answer I tried and modified it without condition it disabled the whole column not that certain cell as I don't have a condition for the item I just want to disable when its been entered only once. I tried this。
编辑：
这是我用于数量的自定义 JFXTextField：
public class JFXTextFieldCell extends TableCell<Item, String> {
private JFXTextField textField;
public JFXTextFieldCell() {
}
@Override
public void startEdit() {
if (!isEmpty()) {
super.startEdit();
createTextField();
setText(null);
setGraphic(textField);
textField.selectAll();
}
}
@Override
public void cancelEdit() {
super.cancelEdit();
setText((String) getItem());
setGraphic(null);
}
@Override
public void updateItem(String item, boolean empty) {
super.updateItem(item, empty);
if (empty) {
setText(item);
setGraphic(null);
} else {
if (isEditing()) {
if (textField != null) {
textField.setText(getString());
// setGraphic(null);
}
setText(null);
setGraphic(textField);
} else {
setText(getString());
setGraphic(null);
}
}
}
private void createTextField() {
textField = new JFXTextField(getString());
textField.setMinWidth(this.getWidth() - this.getGraphicTextGap() * 2);
textField.setOnAction((e) -> commitEdit(textField.getText()));
textField.focusedProperty().addListener((ObservableValue<? extends Boolean> observable, Boolean oldValue, Boolean newValue) -> {
if (!newValue) {
commitEdit(textField.getText());
}
});
}
private String getString() {
return getItem() == null ? "" : getItem();
}
}
简单地禁用（或使 uneditable）当前单元格不起作用；细胞将被重新分配，例如如果用户在 table 周围滚动，那么错误的单元格最终将不是 editable。
您将需要向您的模型添加一些 属性（或在其他地方存储一些可以通过模型实例访问的属性）并实现一个观察这些属性的自定义单元格，更新 editable 适当说明。
像下面这样的东西应该可以工作：
ObservableSet<Item> quantityEditedItems = FXCollections.observableSet();
quantityColumn.setCellFactory(tc -> new TextFieldTableCell<>(new IntegerStringConverter()) {
@Override
public void updateItem(Integer quantity, boolean empty) {
super.updateItem(quantity, empty) ;
editableProperty().unbind();
if (empty) {
setEditable(false);
} else {
editableProperty().bind(Bindings.createBooleanBinding(() ->
! quantityEditedItems.contains(getTableView().getItems().get(getIndex())),
quantityEditedItems));
}
}
});
然后你可以做
quantityColumn.setOnEditCommit(event -> {
StudentPresc user = event.getRowValue(); // should this be Item?
user.setQuantity(event.getNewValue());
updateQuantity("Quantity", event.getNewValue(), user.getID());
quantityEditedItems.add(event.getRowValue());
});
