我的SWT标签不会随着在组合框中选择新项目而更改文本吗？

Question

I am currently using absolute layout and I have a label which is supposed to change as a new item is selected in the combo box I made it work with grid layout but this messes with other functions, buttons and labels I have how would I make this work for me... anything would be appreciated.. this is the part of the code i am talking about:

    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()));


            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);
            lblvarLvlLabel.setText(comboLevels.getText());
            lblvarLvlLabel.getParent().layout();
            /*'''''''''''''.............'''''''''''''''''''''''''''''''''''''''''''*/
            System.out.println("XDDD;"+levelStr1);
        }
    });

I finally found out how to do this i initiated the label outside the action listener so that the label is always there but it .setText and .updates when the item is selected as such:

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();
        }
    });
