tableview 中每一行的列内按钮
button inside column for each row in tableview
在我的 TableView 中，我的每一行都有用于更新的按钮的列，因此我需要在单击按钮时将行中的所有值获取到新的 fxml window
这是我的承包商class:
public class constractor {

private String co_address;
private String co_create_date;
private String co_description;
private String co_mobile;
private String co_type_compile;
private String co_status;
private String co_type_model;
private Button button;
public constractor(String co_id, String co_name, String co_type_compile, String co_description, String co_create_date, String co_status, String co_address, String co_mobile, String co_type_model, String button) {
this.co_id = co_id;
this.co_name = co_name;
this.co_type_compile = co_type_compile;
this.co_description = co_description;
this.co_create_date = co_create_date;

通常建议不要将视图代码 (Button) 与模型代码 (constractor) 混合使用。相反，您应该为列使用自定义 TableCell class。
假设您知道如何传递数据（否则请看这里：Passing Parameters JavaFX FXML），所有必需的信息都应该可以通过您应该传递给新场景的 constractor 实例获得。
主屏幕控制器
@FXML
private TableColumn<constractor, Void> col_button;
...
private void editConstractor(constractor constractor) {
// TODO: implement
}
@FXML
private void initialize() {
col_button.setCellFactory(col -> new TableCell<constractor, Void>() {
private final Button button;
{
button = new Button("edit");
button.setOnAction(evt -> {
constractor item = getTableRow().getItem();
editConstractor(item);
});
}
@Override
protected void updateItem(Void item, boolean empty) {
super.updateItem(item, empty);
setGraphic(empty ? null : button);
}
});
}
您还需要删除按钮列的 cellValueFactory。
注：
- 坚持 java 命名约定会使代码更易于阅读。 （类型名称应以大写字母开头，标识符应使用驼峰式而不是下划线，假设它们不用于
static final 字段。）
constractor 很可能拼错了。您是说 contractor 吗？我建议使用 IDE 的重命名功能来修复此拼写错误...
