我在Scene Builder中生成了以下FXML . 当我在Scene Builder中预览并调整窗口大小时，内部拆分视图会保持自身与锚点视图之间的间距 . 但是当我在我的应用程序中运行FXML时却没有 . 有任何想法吗？我使用的是javafx 2.2.51 .
<?xml version="1.0" encoding="UTF-8"?>
<?import java.lang.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>
<AnchorPane prefHeight="477.0" prefWidth="515.0" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/2.2" fx:controller="com.nm.haze.LibraryViewController">
<children>
<SplitPane dividerPositions="0.09484536082474226" focusTraversable="true" prefHeight="415.0" prefWidth="487.0" AnchorPane.bottomAnchor="14.0" AnchorPane.leftAnchor="14.0" AnchorPane.rightAnchor="14.0" AnchorPane.topAnchor="48.0">
<items>
<AnchorPane minHeight="0.0" minWidth="0.0" prefHeight="160.0" prefWidth="100.0" />
<AnchorPane minHeight="0.0" minWidth="0.0" prefHeight="160.0" prefWidth="100.0">
<children>
<ListView prefHeight="371.0" prefWidth="425.0" AnchorPane.bottomAnchor="0.0" AnchorPane.leftAnchor="0.0" AnchorPane.rightAnchor="0.0" AnchorPane.topAnchor="0.0" />
</children>
</AnchorPane>
</items>
</SplitPane>
</children>
</AnchorPane>
我的控制器代码：
package com.nm.haze;
import java.net.URL;
import java.util.ResourceBundle;
public class LibraryViewController extends BaseController {
@Override
public void initialize(URL url, ResourceBundle resourceBundle) {
}
}
主要代码
private static final String LIBRARY_SELECT = "LibrarySelect";
private static final String LIBRARY_VIEW = "LibraryView";
@Override
public void start(Stage primaryStage) throws IOException {
SceneController sceneController = new SceneController(primaryStage, new SettingsManager());
sceneController.loadScene(LIBRARY_SELECT);
sceneController.loadScene(LIBRARY_VIEW);
if (sceneController.setupNeeded()) {
sceneController.setScreen(LIBRARY_SELECT);
} else {
sceneController.setScreen(LIBRARY_VIEW);
}
Group root = new Group();
root.getChildren().addAll(sceneController);
primaryStage.setScene(new Scene(root));
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
SceneController代码：
public class SceneController extends StackPane {
Map<String, Node> scenes = new HashMap<>();
Stage stage;
SettingsManager settingsManager;
public SceneController(Stage stage, SettingsManager settingsManager) {
this.stage = stage;
this.settingsManager = settingsManager;
}
public void addScene(String name, Node scene) {
scenes.put(name, scene);
}
public void loadScene(String name) throws IOException {
FXMLLoader myLoader = new FXMLLoader(getClass().getResource(name + ".fxml"));
Parent loadScreen = (Parent)myLoader.load();
((BaseController)myLoader.getController()).setSceneController(this);
addScene(name, loadScreen);
}
public void setScreen(final String name) {
List<Node> children = getChildren();
Node scene = scenes.get(name);
if(scene != null) {
if (children.size() > 0) {
children.remove(0);
}
children.add(0, scene);
} else {
throw new IllegalArgumentException("Scene has not been loaded");
}
}
public Stage getStage() {
return stage;
}
public boolean setupNeeded() {
return settingsManager.setupNeeded();
}
}
要清楚问题是什么，请参阅下面的截图前后截图 . ListView 和 AnchorPane 之间的距离应该保持不变（在Scene Builder中也是如此） .

`您只需要修复SplitPane部分的最小和最大宽度，在调整窗口大小时您不想更改其宽度！
在这里，我通过设置
minWidth的minWidth和maxWidth来修复左侧部分 . 根据您的要求，您也可以在右侧执行相同的操作 .abcFxml.fxml

EDIT ：根据用户更新
您遇到的问题是因为您使用的是
Group. 集团本身不可调整大小！尝试将StackPane直接放到场景中（就像我一样）或者你可以使用任何其他容器，如VBOX/HBOX等
