    Combo comboLevels = new Combo(shellAfterCasual, SWT.NONE);
    comboLevels.setBounds(10, 40, 91, 23);
    String[] item = new String[] { "Swedish 1", "Swedish 2", "Swedish 3" };

我终于找到了如何做到这一点，我开始动作监听外的标签，使标签是永远存在的，但它.setText和.updates项目时作如此选择：

Label lblvarLvlLabel = new Label(shellAfterCasual, SWT.NONE);
    lblvarLvlLabel.setFont(SWTResourceManager.getFont("Segoe UI", 12, SWT.BOLD | SWT.ITALIC));
    lblvarLvlLabel.setBackground(SWTResourceManager.getColor(SWT.COLOR_INFO_BACKGROUND));
    lblvarLvlLabel.setBounds(145, 5, 107, 27);


    Combo comboLevels = new Combo(shellAfterCasual, SWT.NONE);
    comboLevels.setBounds(10, 40, 91, 23);
    String[] item = new String[] { "Swedish 1", "Swedish 2", "Swedish 3" };
    comboLevels.setItems(new String[] {"Swedish 1", "Swedish 2", "Swedish 3"});
    comboLevels.addSelectionListener(new SelectionAdapter() {
        @Override
        public void widgetSelected(SelectionEvent e) {
             levelStr1 = comboLevels.getItem(comboLevels.getSelectionIndex());
            System.out.println("Selection: " + comboLevels.getItem(comboLevels.getSelectionIndex()));
            lblvarLvlLabel.setText(comboLevels.getText());
            lblvarLvlLabel.getParent().layout();
            lblvarLvlLabel.redraw();
            lblvarLvlLabel.update();
        }
    });
