import org.eclipse.swt.SWT;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.Spinner;
public class SpinnerCreateInit {
  public static void main(String[] args) {
    Display display = new Display();
    Shell shell = new Shell(display);
    Spinner spinner = new Spinner(shell, SWT.BORDER);
    spinner.setMinimum(0);
    spinner.setMaximum(1000);
    spinner.setSelection(500);
    spinner.setIncrement(1);
    spinner.setPageIncrement(100);
    spinner.pack();
    shell.pack();
    shell.open();
    while (!shell.isDisposed()) {
      if (!display.readAndDispatch())
        display.sleep();
    }
    display.dispose();
  }

Floating point values in Spinner

import org.eclipse.swt.SWT;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.Spinner;
public class SpinnerFloatPoint {
  public static void main(String[] args) {
    Display display = new Display();
    Shell shell = new Shell(display);
    shell.setText("Spinner with float values");
    shell.setLayout(new GridLayout());
    final Spinner spinner = new Spinner(shell, SWT.NONE);
    // allow 3 decimal places
    spinner.setDigits(3);
    // set the minimum value to 0.001
    spinner.setMinimum(1);
    // set the maximum value to 20
    spinner.setMaximum(20000);
    // set the increment value to 0.010
    spinner.setIncrement(10);
    // set the seletion to 3.456
    spinner.setSelection(3456);
    shell.setSize(200, 200);
    shell.open();
    while (!shell.isDisposed()) {
      if (!display.readAndDispatch())
        display.sleep();
    }
    display.dispose();
