In this test  SelectionEvent.detail always returns 0 and does not match any of
these values SWT.ARROW_LEFT , SWT.ARROW_RIGHT , SWT.PAGE_UP , SWT.PAGE_DOWN, 
SWT.DRAG. Thus it just exits not giving any expected results.
Here  is the test case:

import org.eclipse.swt.SWT;
import org.eclipse.swt.events.SelectionAdapter;
import org.eclipse.swt.events.SelectionEvent;
import org.eclipse.swt.layout.RowLayout;
import org.eclipse.swt.widgets.*;

public class TestSWTSliderEvent {
	static int value;
	public static void main(String[] args) {

		Display disp = Display.getDefault();
		Shell shell = new Shell(disp);
		shell.setLayout(new RowLayout(SWT.VERTICAL));
		final Slider slide = new Slider(shell, SWT.HORIZONTAL);
		slide.addSelectionListener(new SelectionAdapter() {
			public void widgetSelected(SelectionEvent e) {
				int newValue = slide.getSelection();
				System.out.println("New value = " + newValue);
				if (value == newValue) {
					return;
				}
				System.out.println("e.detail is : " + e.detail);
				switch (e.detail) {
					case SWT.PAGE_UP :
						System.out.println(
							"Page up, selection is: " + newValue);
						break;
					case SWT.PAGE_DOWN :
						System.out.println(
							"Page down, selection is: " + newValue);
						break;
					case SWT.ARROW_UP :
						System.out.println(
							"Arrow up, selection is: " + newValue);
						break;
					case SWT.ARROW_DOWN :
						System.out.println(
							"Arrow down, selection is: " + newValue);
						break;
					case SWT.DRAG :
						System.out.println(
							"Dragged, selection is: " + newValue);
						break;
					default :
						return;
				}
				value = newValue;
				System.out.println("about to post an adjustment event..");

			}
		});
		shell.setSize(150, 150);
		shell.open();

		while (!shell.isDisposed()) {
			if (!disp.readAndDispatch()) {
				disp.sleep();
			}
		}

}
