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:

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.

// and add labels to it

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); 

    } 
}
