在Javafx中,Treeview的DisclosureNode默认在左侧。如何将Disclosure Node置于右侧(向右浮动).. ?? 任何帮助将不胜感激。

您只需要设置节点方向以获得从右到左的行为。但请注意,此TreeView的所有子项都将继承该方向作为默认值。
import javafx.application.Application;
import javafx.geometry.NodeOrientation;
import javafx.scene.Scene;
import javafx.scene.control.TreeItem;
import javafx.scene.control.TreeView;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;
public class TreeViewRightLeft extends Application {
@Override
public void start(Stage primaryStage) {
TreeItem<String> item = new TreeItem<>("Root Node");
item.setExpanded(true);
item.getChildren().addAll(
new TreeItem<>("Item 1"),
new TreeItem<>("Item 2"),
new TreeItem<>("Item 3")
);
TreeView<String> treeView = new TreeView<>(item);
// Here you can select the orientation.
treeView.setNodeOrientation(NodeOrientation.RIGHT_TO_LEFT);
BorderPane root = new BorderPane(treeView);
Scene scene = new Scene(root, 300, 250);
primaryStage.setTitle("TreeView");
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
