Create Tabs in Java using SWT

SWT provides the classes TabFolder and TabItem to create tabs. The class TabFolder allows the user to select a page from set of pages which is in the form of tabs. The class TabItem adds a page in the folder in the form of tab. the method item.setText() sets the text to the tabItem.

The method tabFolder.setSize() sets the size of tabFolder. The method getSelection() returns an array of TabItem that are currently selected.

Following code create the tabs:

for (int i=1; i<5; i++) {
TabItem item = new TabItem (tabFolder, SWT.NULL);
item.setText ("Tab" + i);

Here is the code of TabExample.java


import org.eclipse.swt.SWT;

import org.eclipse.swt.events.*;

import org.eclipse.swt.widgets.*;

import org.eclipse.swt.layout.FillLayout;



public class TabExample {

  Display display = new Display();

  Shell shell = new Shell(display);

  

  public TabExample() {

  shell.setLayout(new FillLayout());

  shell.setText("Tabs");

 

  final TabFolder tabFolder = new TabFolder (shell, SWT.NONE);

  for (int i=1; i<5; i++) {

 TabItem item = new TabItem (tabFolder, SWT.NULL);

 item.setText ("Tab" + i);

 Text text = new Text(tabFolder, SWT.BORDER | SWT.MULTI);

 text.setText("This is Tab "+i);

 item.setControl(text);

 }

 tabFolder.setSize (250, 150);

 tabFolder.addSelectionListener(new SelectionListener() {

 public void widgetSelected(SelectionEvent e) {

 System.out.println("You have selected:"+ tabFolder.getSelection()

  [0].toString());

 }

 public void widgetDefaultSelected(SelectionEvent e) {

  widgetSelected(e);

  }

  });

  shell.setSize(200, 150);

  shell.open();

  

  while (!shell.isDisposed()) {

  if (!display.readAndDispatch()) {

  display.sleep();

  }

  }

  display.dispose();

  }

 public static void main(String[] args) {

  new TabExample();
