演示代码如下: 
 
package swt_jface.demo9; 
import org.eclipse.swt.SWT; 
import org.eclipse.swt.widgets.Display; 
import org.eclipse.swt.widgets.Event; 
import org.eclipse.swt.widgets.Listener; 
import org.eclipse.swt.widgets.Sash; 
import org.eclipse.swt.widgets.Shell; 
public class SashExample { 
public static void main(String[] args) { 
Display display = new Display(); 
Shell shell = new Shell(display); 
final Sash sash = new Sash(shell, SWT.BORDER | SWT.VERTICAL); 
sash.setBounds(10, 10, 15, 60); 
sash.addListener(SWT.Selection, new Listener() { 
public void handleEvent(Event e) { 
System.out.println("Selected. "); 
sash.setBounds(e.x, e.y, e.width, e.height); 
} 
}); 
shell.open(); 
sash.setFocus(); 
while (!shell.isDisposed()) { 
if (!display.readAndDispatch()) 
display.sleep(); 
} 
display.dispose(); 
} 
} 
package swt_jface.demo9; 
import org.eclipse.swt.SWT; 
import org.eclipse.swt.widgets.Display; 
import org.eclipse.swt.widgets.Event; 
import org.eclipse.swt.widgets.Listener; 
import org.eclipse.swt.widgets.Sash; 
import org.eclipse.swt.widgets.Shell; 
public class SashExample { 
    public static void main(String[] args) { 
        Display display = new Display(); 
        Shell shell = new Shell(display); 
        final Sash sash = new Sash(shell, SWT.BORDER | SWT.VERTICAL); 
        sash.setBounds(10, 10, 15, 60); 
        sash.addListener(SWT.Selection, new Listener() { 
            public void handleEvent(Event e) { 
                System.out.println("Selected. "); 
                sash.setBounds(e.x, e.y, e.width, e.height); 
            } 
        }); 
        shell.open(); 
        sash.setFocus(); 
        while (!shell.isDisposed()) { 
            if (!display.readAndDispatch()) 
                display.sleep(); 
        } 
        display.dispose(); 
    } 
} 
 再来一个例子: 
 
package swt_jface.demo9; 
import org.eclipse.swt.SWT; 
import org.eclipse.swt.custom.SashForm; 
import org.eclipse.swt.events.ControlEvent; 
import org.eclipse.swt.events.ControlListener; 
import org.eclipse.swt.events.MouseEvent; 
import org.eclipse.swt.events.MouseListener; 
import org.eclipse.swt.layout.FillLayout; 
import org.eclipse.swt.widgets.Display; 
import org.eclipse.swt.widgets.Label; 
import org.eclipse.swt.widgets.Shell; 
import org.eclipse.swt.widgets.Text; 
public class SashFormExample { 
Display display = new Display(); 
Shell shell = new Shell(display); 
SashForm sashForm; 
SashForm sashForm2; 
public SashFormExample() { 
shell.setLayout(new FillLayout()); 
sashForm = new SashForm(shell, SWT.HORIZONTAL); 
Text text1 = new Text(sashForm, SWT.CENTER); 
text1.setText("Text in pane #1"); 
Text text2 = new Text(sashForm, SWT.CENTER); 
text2.setText("Text in pane #2"); 
sashForm2 = new SashForm(sashForm, SWT.VERTICAL); 
final Label labelA = new Label(sashForm2, SWT.BORDER | SWT.CENTER); 
labelA.setText("Label in pane A"); 
final Label labelB = new Label(sashForm2, SWT.BORDER |SWT.CENTER); 
labelB.setText("Label in pane B"); 
text1.addControlListener(new ControlListener() { 
public void controlMoved(ControlEvent e) { 
} 
public void controlResized(ControlEvent e) { 
System.out.println("Resized"); 
//ArrayUtil.printArray(sashForm.getWeights(), System.out); 
} 
}); 
sashForm.setWeights(new int[]{1, 2, 3}); 
labelA.addMouseListener(new MouseListener() { 
public void mouseDoubleClick(MouseEvent e) { 
if(sashForm2.getMaximizedControl() == labelA) 
sashForm2.setMaximizedControl(null); 
else 
sashForm2.setMaximizedControl(labelA); 
} 
public void mouseDown(MouseEvent e) { 
} 
public void mouseUp(MouseEvent e) { 
} 
}); 
shell.setSize(450, 200); 
shell.open(); 
while (!shell.isDisposed()) { 
if (!display.readAndDispatch()) { 
display.sleep(); 
} 
} 
display.dispose(); 
} 
public static void main(String[] args) { 
new SashFormExample(); 
} 
}
