Add an event listener to write the selected tab to stdout

import org.eclipse.swt.SWT;
import org.eclipse.swt.events.SelectionAdapter;
import org.eclipse.swt.widgets.Button;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.TabFolder;
import org.eclipse.swt.widgets.TabItem;
public class TabFolderSelectionEvent {
  public static void main(String[] args) {
    Display display = new Display();
    final Shell shell = new Shell(display);
    final TabFolder tabFolder = new TabFolder(shell, SWT.BORDER);
    for (int i = 0; i < 6; i++) {
      TabItem item = new TabItem(tabFolder, SWT.NONE);
      item.setText("TabItem " + i);
      Button button = new Button(tabFolder, SWT.PUSH);
      button.setText("Page " + i);
      item.setControl(button);
    }
    // Add an event listener to write the selected tab to stdout
    tabFolder.addSelectionListener(new SelectionAdapter() {
      public void widgetSelected(org.eclipse.swt.events.SelectionEvent event) {
        System.out.println(tabFolder.getSelection()[0].getText() + " selected");
      }
    });
    
    tabFolder.pack();
    shell.pack();
    shell.open();
    while (!shell.isDisposed()) {
      if (!display.readAndDispatch())
        display.sleep();
    }
    display.dispose();
  }
}

Create TabFolder and add TabItem

1. SWT divides its tab implementation into two classes: TabFolder and TabItem.
2. TabFolders, which aren"t visible, contain TabItems.
3. To create a tabbed interface, create a TabFolder with a Shell as its parent, and create TabItems as children of the TabFolder.

import org.eclipse.swt.SWT;
import org.eclipse.swt.widgets.Button;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.TabFolder;
import org.eclipse.swt.widgets.TabItem;
public class TabFolderTabItem {
  public static void main(String[] args) {
    Display display = new Display();
    final Shell shell = new Shell(display);
    final TabFolder tabFolder = new TabFolder(shell, SWT.BORDER);
    for (int i = 0; i < 6; i++) {
      TabItem item = new TabItem(tabFolder, SWT.NONE);
      item.setText("TabItem " + i);
      Button button = new Button(tabFolder, SWT.PUSH);
      button.setText("Page " + i);
      item.setControl(button);
    }
    tabFolder.pack();
    shell.pack();
    shell.open();
    while (!shell.isDisposed()) {
      if (!display.readAndDispatch())
        display.sleep();
    }
    display.dispose();
  }
}

Set selected tab

import org.eclipse.swt.SWT;
import org.eclipse.swt.widgets.Button;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.TabFolder;
import org.eclipse.swt.widgets.TabItem;
public class TabItemSelection {
  public static void main(String[] args) {
    Display display = new Display();
    final Shell shell = new Shell(display);
    final TabFolder tabFolder = new TabFolder(shell, SWT.BORDER);
    for (int i = 0; i < 6; i++) {
      TabItem item = new TabItem(tabFolder, SWT.NONE);
      item.setText("TabItem " + i);
      Button button = new Button(tabFolder, SWT.PUSH);
      button.setText("Page " + i);
      item.setControl(button);
    }
    tabFolder.setSelection(2);
    
    tabFolder.pack();
    shell.pack();
    shell.open();
    while (!shell.isDisposed()) {
      if (!display.readAndDispatch())
        display.sleep();
    }
    display.dispose();
  }
}
