跨嵌入式场景的 TextField textProperty Listener JavaFX
TextField textProperty Listener across embedded scenes JavaFX
这可能有点令人费解，但请耐心等待。
我有 3 个场景是使用 SceneBuilder 构建的。第一个 ("Main") 我用作父场景。此场景包含 1 个 AnchorPane，其中包含一个 TabPane 和一个 ToolBar，其中包含 3 个 Buttons（"Previous"、"Next" 和 "Close" ).
第二个场景（"PersonaDetails"）包含一个AnchorPane，一个GridPane多个Textflow（我将其用作字段标签）几个TextField 和 DatePicker。整个场景嵌入到第一个场景 ("Main") 的 TabPane 的一个选项卡中。
第三个场景 ("Address") 与第二个非常相似，其中包含一个 AnchorPane、一个 GridPane 多个 Textflow（我正在使用作为字段标签）几个 TextField 和 ComboBox。整个场景嵌入到第一个场景 ("Main") 的 TabPane 的另一个选项卡中。
（我已经包含了下面每个的 FXML 脚本）
应用程序稍后将在第一个场景 ("Main") 的 TabPane 的附加选项卡上包含附加场景。此应用程序将构成更大应用程序的一部分，旨在成为一种允许注册新客户的向导。
此外，每个 FXML 文件及其控制器都在单独的包中。
我遇到的这个问题是我需要在几个 Textfield 上添加 .textProperty() 侦听器，以便我可以启用或禁用 [=73=] Button在第一个或父场景中 ("Main")。
我已经在 MainController class 中尝试了以下代码，但它不起作用，尽管它不会产生任何错误。

项目的文件夹结构如下图所示：
首先，我对问题中的 "scene" 措辞有点困惑。我相信你在问题中提到的是关于处理节点的，因为所有的 fxml 都是在同一个 Scene/Stage.
中处理的
总之，问题的主要出在MainController的initialize方法上。您正在加载 PersonalDetailsController 的新实例并对其进行处理，而不是处理实际绑定到 MainController 的控制器。
当在 fxml 中包含 fxml 时，子 fxml 的控制器将已经注入到主 fxml 控制器中。所以我相信如下更改 MainController 代码应该会按预期工作。
更新： 抱歉有点误导性的信息。正确的是，您需要使用特定的命名约定注入控制器。如果您使用 fx:include 包含 fxml，要获取控制器，您需要注入命名约定 <fxid>Controller 和 <fxid> 以获取节点引用。
因此，考虑到您的示例，对于给定的 fx:include 行：
<fx:include fx:id="apPersonalDetails" source="../personaldetails/PersonalDetails.fxml" />
您在 MainController 中的代码应该是：
// For controller reference
@FXML PersonalDetailsController apPersonalDetailsController;
// For Node reference
@FXML AnchorPane apPersonalDetails;
所以更新后的代码如下：
import com.yas.registrationwizard.personaldetails.PersonalDetailsController;
import javafx.fxml.FXML;
import javafx.fxml.FXMLLoader;
import javafx.fxml.Initializable;
import javafx.scene.control.Button;
import javafx.scene.control.TabPane;
import javafx.scene.control.ToolBar;
import javafx.scene.layout.AnchorPane;
import java.io.IOException;
import java.net.URL;
import java.util.ResourceBundle;
public class MainController implements Initializable {
@FXML AnchorPane apMain;
@FXML ToolBar tbMain;
@FXML TabPane tpMain;
@FXML Button btnPrevious;
@FXML Button btnNext;
@FXML Button btnClose;
@FXML PersonalDetailsController apPersonalDetailsController;
@Override
public void initialize(URL location, ResourceBundle resources) {
apPersonalDetailsController.tfFirstName.textProperty().addListener((obs, oldVal, newVal) -> {
if(newVal.equals("")) {
btnNext.setDisable(true);
} else {
btnNext.setDisable(false);
}
});
}
}

项目的文件夹结构如下图所示：
首先，我对问题中的 "scene" 措辞有点困惑。我相信你在问题中提到的是关于处理节点的，因为所有的 fxml 都是在同一个 Scene/Stage.
中处理的总之，问题的主要出在MainController的initialize方法上。您正在加载 PersonalDetailsController 的新实例并对其进行处理，而不是处理实际绑定到 MainController 的控制器。
当在 fxml 中包含 fxml 时，子 fxml 的控制器将已经注入到主 fxml 控制器中。所以我相信如下更改 MainController 代码应该会按预期工作。
更新： 抱歉有点误导性的信息。正确的是，您需要使用特定的命名约定注入控制器。如果您使用 fx:include 包含 fxml，要获取控制器，您需要注入命名约定 <fxid>Controller 和 <fxid> 以获取节点引用。
因此，考虑到您的示例，对于给定的 fx:include 行：
<fx:include fx:id="apPersonalDetails" source="../personaldetails/PersonalDetails.fxml" />
您在 MainController 中的代码应该是：
// For controller reference
@FXML PersonalDetailsController apPersonalDetailsController;
// For Node reference
@FXML AnchorPane apPersonalDetails;
所以更新后的代码如下：
import com.yas.registrationwizard.personaldetails.PersonalDetailsController;
import javafx.fxml.FXML;
import javafx.fxml.FXMLLoader;
import javafx.fxml.Initializable;
import javafx.scene.control.Button;
import javafx.scene.control.TabPane;
import javafx.scene.control.ToolBar;
import javafx.scene.layout.AnchorPane;
import java.io.IOException;
import java.net.URL;
import java.util.ResourceBundle;
public class MainController implements Initializable {
@FXML AnchorPane apMain;
@FXML ToolBar tbMain;
@FXML TabPane tpMain;
@FXML Button btnPrevious;
@FXML Button btnNext;
@FXML Button btnClose;
@FXML PersonalDetailsController apPersonalDetailsController;
@Override
public void initialize(URL location, ResourceBundle resources) {
apPersonalDetailsController.tfFirstName.textProperty().addListener((obs, oldVal, newVal) -> {
if(newVal.equals("")) {
btnNext.setDisable(true);
} else {
btnNext.setDisable(false);
}
});
}
}
