SWT如何在当前窗口中打开新窗口？

请问，SWT中，如何实现在当前窗口中打开一个新窗口？由于刚接触SWT，还不懂改如何实现，谢谢！

需要给控件添加事件监听,在事件执行中就可以去写打开另一个Dialog的代码了.

[code="java"] final Button button = new Button(shell, SWT.NONE);

button.addSelectionListener(new SelectionAdapter() {

public void widgetSelected(SelectionEvent e) {

new CustomDialog(Display.getCurrent().getActiveShell()).open();

}

}); [/code]

[code="java"]import org.eclipse.swt.SWT;
import org.eclipse.swt.events.SelectionAdapter;
import org.eclipse.swt.events.SelectionEvent;
import org.eclipse.swt.widgets.Button;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;

public class SwtApplication {
protected Shell shell;

public static void main(String[] args) throws Exception {
    SwtApplication window = new SwtApplication();
    window.open();
}

public void open() {
    final Display display = Display.getDefault();
    createContents();
    shell.open();
    shell.layout();
    while (!shell.isDisposed()) {
        if (!display.readAndDispatch()) {
            display.sleep();
        }
    }
}

protected void createContents() {
    shell = new Shell();
    shell.setSize(500, 375);
    shell.setText("SWT");

    final Button button = new Button(shell, SWT.NONE);
    button.addSelectionListener(new SelectionAdapter() {
        public void widgetSelected(SelectionEvent e) {
            new CustomDialog(Display.getCurrent().getActiveShell()).open();
        }
    });
    button.setText("button");
    button.setBounds(438, 308, 44, 23);
}

}[/code]

[code="java"]import org.eclipse.swt.SWT;
import org.eclipse.swt.widgets.Button;
import org.eclipse.swt.widgets.Dialog;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;

public class CustomDialog extends Dialog {
protected Object result;
protected Shell shell;

public CustomDialog(Shell parent) {
    super(parent, SWT.NONE);
}

public Object open() {
    createContents();
    shell.open();
    shell.layout();
    Display display = getParent().getDisplay();
    while (!shell.isDisposed()) {
        if (!display.readAndDispatch())
            display.sleep();
    }
    return result;
}

protected void createContents() {
    shell = new Shell(getParent(), SWT.DIALOG_TRIM | SWT.APPLICATION_MODAL);
    shell.setSize(312, 212);
    shell.setText("SWT Dialog");

    final Button button = new Button(shell, SWT.NONE);
    button.setText("button");
    button.setBounds(127, 74, 44, 23);
}

}[/code]
