如何在將一個FXML加載到AnchorPane時自動調整大小？

我在加載到AnchorPane中的FXML的佈局時遇到了問題。如何在將一個FXML加載到AnchorPane時自動調整大小？

我有一個AnchorPane和一個按鈕的Scene.fxml。按下按鈕將Internal.fxml加載到AnchorPane中。 Internal.fxml具有一個將AnchorPane Constraints設置爲左側和右側的TextField。就是這樣。

雖然現在調整窗口大小時TextField不會調整大小。

爲什麼TextField不能自行調整大小？下面代碼中的錯誤在哪裏？

Main.java：

@Override 
public final void start(final Stage firstStage) throws Exception { 
    Parent mask = FXMLLoader.load(getClass() 
          .getResource("/fxml/Scene.fxml")); 

    Scene scene = new Scene(mask); 
    scene.getStylesheets().add("/styles/Styles.css"); 

    firstStage.setTitle("MyProgram"); 
    firstStage.setScene(scene); 
    firstStage.show(); 

    Main.stage = firstStage; 
}

Scene.fxml：

<?xml version="1.0" encoding="UTF-8"?> 

<?import java.lang.*?> 
<?import java.util.*?> 
<?import javafx.geometry.*?> 
<?import javafx.scene.*?> 
<?import javafx.scene.control.*?> 
<?import javafx.scene.layout.*?> 
<?import javafx.scene.text.*?> 

<AnchorPane id="AnchorPane" fx:id="content" prefHeight="600.0" prefWidth="800.0" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/2.2" fx:controller="com.treasury.myprogram.controller.SceneController"> 
    <children> 
    <Button layoutX="257.0" layoutY="227.0" mnemonicParsing="false" onAction="#loadInternal" text="Button" /> 
    </children> 
</AnchorPane>

Internal.fxml：

<?xml version="1.0" encoding="UTF-8"?> 

<?import java.lang.*?> 
<?import java.util.*?> 
<?import javafx.scene.control.*?> 
<?import javafx.scene.layout.*?>

<AnchorPane id="AnchorPane" maxHeight="-1.0" maxWidth="-1.0" minHeight="400.0" minWidth="600.0" prefHeight="-1.0" prefWidth="-1.0" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/2.2" fx:controller="com.treasury.myprogram.controller.InternalController"> 
    <children> 
    <TextField layoutY="14.0" prefWidth="-1.0" AnchorPane.leftAnchor="14.0" AnchorPane.rightAnchor="14.0" /> 
    </children> 
</AnchorPane>

SceneController.java：

package com.treasury.myprogram.controller; 

import java.io.IOException; 
import java.net.URL; 
import java.util.ResourceBundle; 
import javafx.fxml.FXML; 
import javafx.fxml.FXMLLoader; 
import javafx.fxml.Initializable; 
import javafx.scene.layout.AnchorPane; 

public class SceneController implements Initializable { 
    @FXML 
    private AnchorPane content; 


    @FXML 
    private void loadInternal() { 
     try { 
      AnchorPane internalPane = FXMLLoader.load(getClass().getResource("/fxml/Internal.fxml")); 

      this.content.getChildren().setAll(internalPane); 

     } catch (IOException ex) { 
      System.out.println("Internal error: " + ex.getMessage()); 
     } 
    } 

    @Override 
    public void initialize(URL url, ResourceBundle rb) { 
    } 
}

編輯：

好吧，首先感謝很多，現在的代碼工作。那麼，其中的一半呢，但至少第一個問題已經消失了。我現在有一個FXML只能工作一半。它有一個GridPane，下面有幾個條目和一個TextField。他們都直接在AnchorPane上。現在，當我處於JavaFX Scene Builder 1.1的構建模式時，一切都很正常，但是當我將此Internal.fxml加載到Scene.fxml中時，只有TextField適應Parent大小，但GridPane不適用。我無法找到原因。什麼問題？錯配在哪裏？

嘗試使用BorderPane而非錨窗格和兒童FXML的對象設置成中心。同時檢查父級fxml是否在scene builder中爲atuo resizabel。

@FXML private BorderPane bPaneHomeChild; 
FXMLLoader loader = new FXMLLoader(getClass.getResource("/fxml/Internal.fxml")); 
Pane cmdPane = (Pane) loader.load(); 
bPaneHomeChild.setCenter(cmdPane);

我發佈了一個編輯我的問題與不工作的FXML爲例。 – Socrates

意思是現在你的問題解決了？ –

此解決方案適用於我。謝謝Rajeev – Menefee

嘗試這樣的：

AnchorPane.setTopAnchor(<child node>,0.0); 
AnchorPane.setBottomAnchor(<child node>,0.0); 
AnchorPane.setLeftAnchor(<child node>,0.0); 
AnchorPane.setRightAnchor(<child node>,0.0);

我上面發佈了一個修改。 – Socrates

選擇GridPane左手邊，然後單擊它周圍的陰影區域。然後選擇Vgrow和Hgrow在「佈局」面板的右側「始終」。這樣的：
