JavaFX | SplitPane Class

SplitPane class is a part of JavaFX. SplitPane class is a control which contains two or more sides separated by a divider. Sides can be dragged by the user to give more space to one of the sides which cause the other side to shrink by an equal amount. SplitPane class inherits Control class.

Constructor of the Class:

• SplitPane(): Creates a new SplitPane.
• SplitPane(Node… n): Creates a SplitPane with specified nodes.

Commonly Used Methods:

Method	Explanation
getItems()	Returns the items of the split pane.
getOrientation()	Returns the orientation of split pane.
setDividerPosition(int dividerIndex, double position)	Sets the position of divider at specified index.
setDividerPositions(double… p)	Sets the position of dividers.
setOrientation(Orientation o)	Sets the orienattion of splitpane.

Below programs illustrate the use of SplitPane Class:

1. Java program to create a split pane and add labels to it:
   • In this program, we will create a SplitPane name split_pane.
   • Create and add labels to the split pane using getItems().add() function.
   • Add the split_pane to the scene and add the scene to the stage.
   • Call the show() function to display the final results.

   // Java program to create a split pane
   // and add labels to it
   import javafx.application.Application;
   import javafx.scene.Scene;
   import javafx.scene.control.*;
   import javafx.scene.layout.*;
   import javafx.stage.Stage;
   import javafx.scene.layout.*;
   import javafx.scene.paint.*;
   import javafx.scene.text.*;
   import javafx.geometry.*;
   import javafx.scene.layout.*;
   import javafx.scene.shape.*;
   import javafx.scene.paint.*;
   import javafx.scene.*;
   import java.io.*;
   import javafx.scene.image.*;
   
   public class SplitPane_1 extends Application {
   
       // launch the application
       public void start(Stage stage)
       {
   
           try {
   
               // set title for the stage
               stage.setTitle("Split Pane");
   
               // create a splitpane
               SplitPane split_pane = new SplitPane();
   
               // create labels and add it to splitPane
               for (int i = 1; i < 5; i++) {
   
                   split_pane.getItems().add(new Label("\tLabel no "
                                                       + i + "\t"));
               }
   
               // create a scene
               Scene scene = new Scene(split_pane, 500, 300);
   
               // set the scene
               stage.setScene(scene);
   
               stage.show();
           }
   
           catch (Exception e) {
   
               System.out.println(e.getMessage());
           }
       }
   
       // Main Method
       public static void main(String args[])
       {
   
           // launch the application
           launch(args);
       }
   }

   Output:

   

2. Java program to create a split pane set its orientation and add labels to it:
   • In this program we will create a SplitPane name split_pane.
   • Create and add labels to the split pane using getItems().add() function.
   • Add the split_pane to the scene and add the scene to the stage.
   • Set the orientation of the split_pane using the setOrientation() function.
   • Call the show() function to display the final results.

   // Java program to create a split pane, set
   // its orientation and add labels to it

   public class SplitPane_2 extends Application {

       {
   
           try {

               stage.setTitle("Split Pane");
   
               // create a splitpane
               SplitPane split_pane = new SplitPane();
   
               // create labels and add it to splitPane
               for (int i = 1; i < 5; i++) {
   
                   // create a label
                   Label label = new Label("\tLabel no " + i + "\t");
   
                   // set preferred height
                   label.setPrefHeight(50);
   
                   split_pane.getItems().add(label);
               }
   
               // set Orientation of splitpane
               split_pane.setOrientation(Orientation.VERTICAL);
   
               // create a scene
               Scene scene = new Scene(split_pane, 500, 300);
   
               // set the scene
               stage.setScene(scene);
   
               stage.show();
           }
   
           catch (Exception e) {
   
               System.out.println(e.getMessage());
           }
       }
   
       // Main Method
       public static void main(String args[])
       {
   
           // launch the application
           launch(args);
       }
   }
