Hello friend,

I am beginner to the advanced java programming. I need you help to know about the JSplitPane class of java. This class of java seems very complicated to understand. I don't have any idea about it's constructors and methods. If you have sound knowledge regarding JSplitPane class of java, then please let me know the same. Suitable example over JSplitPane class will be greatly appreciated.

Hi,

SplitPane is used to divide two (and only two) Components. The two Components are graphically divided based on the look and feel implementation, and the two Components can then be interactively resized by the user. The two Components in a split pane can be aligned left to right using JSplitPane.HORIZONTAL_SPLIT, or top to bottom using JSplitPane.VERTICAL_SPLIT. The preferred way to change the size of the Components is to invoke setDividerLocation where location is either the new x or y position, depending on the orientation of the JSplitPane.

Please refer following example of JSplitPane class of java:

import javax.swing.JSplitPane;

public class JSplitPaneDemo{
  
  public static void main(String[] a) {
   int HORIZSPLT = JSplitPane.HORIZONTAL_SPLIT;
    int VERTSPLT = JSplitPane.VERTICAL_SPLIT;

    boolean continuousLayout = true;
    JLabel labelv1 = new JLabel("a");
    JLabel labelv2 = new JLabel("b");
    JLabel labelv3 = new JLabel("c");
    JSplitPane splitPane01 = new JSplitPane(VERTSPLIT, continuousLayout, label1, label2);
    splitPane01.setOneTouchExpandable(true);
    splitPane01.setDividerSize(2);
    splitPane01.setDividerLocation(0.5);

    JSplitPane splitPane2 = new JSplitPane(HORIZSPLIT, splitPane01, label3);
    splitPane2.setOneTouchExpandable(true);
    splitPane2.setDividerLocation(0.4);
    splitPane2.setDividerSize(2);

    JFrame frame07 = new JFrame();
    frame07.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame07.add(splitPane2);
    frame07.pack();
    frame07.setVisible(true);
  }
}

Hello friend,

Following are some constructors of JSplitPane class along with different parameters:

• JSplitPane(int newOrn, Component newLeftComp, Component newRightComp)
• JSplitPane(int newOrn, boolean newContinuousLyt, Component newLeftComp, Component newRightComp)
• JSplitPane(int newOrn, boolean newContinuousLyt)
• JSplitPane(int newOrn)
• JSplitPane()

Following part of java program will demonstrate you the use of JSplitPane class of java, please review it carefully:

public JSplitPane()
JSplitPane splitPn = new JSplitPane();
public JSplitPane(int Orn)
JSplitPane splitPn = new JSplitPane(JSplitPane.VERTICAL_SPLIT);

public JSplitPane(int Orn, Component newLeftComponent, Component newRightComponent)
JComponent topComponent = new JButton("Top Button");
JComponent bottomComponent = new JButton("Bottom Button");
JSplitPane splitPn = new JSplitPane(JSplitPane.VERTICAL_SPLIT, topComponent, bottomComponent);

public JSplitPane(int Orn, boolean newContinuousLayout)
JSplitPane splitPn = new JSplitPane(JSplitPane.VERTICAL_SPLIT, true);

public JSplitPane(int Orn, boolean newContinuousLayout, Component newLeftComponent, Component newRightComponent)
JSplitPane splitPn = new JSplitPane(JSplitPane.VERTICAL_SPLIT, true, topComponent, bottomComponent);

Hi friend,

To make use use of JSplitPane class, you need to be aware about following important methods of this class:

1. setUI(SplitPaneUI sui)
2. setTopComponent(Component compn)
3. setRightComponent(Component compn)
4. setResizeWeight(double val)
5. setOrientation(int ortn)
6. setOneTouchExpandable(boolean newVal)
