How to get Treeview DisclosureNode to right , in Javafx? - javafx

Question

In Javafx the DisclosureNode of Treeview is on left by default. How can I I place the Disclosure Node to Right (float right)..??
Any Help would be appreciated.

You only need to set the Node Orientation to get a right to left behaviour. But be aware of, that all childrens of this TreeView will inherit the orientation as a default.
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);
}
}
Right to Left
Left to Right (default)
