    Default SWT: How to return updated combo item after selectionlistener and save it to disk

    Hello my SWT friends

    I am confused with selectionlistener in Eclipse SWT.
    I want to save the updated combo items after it has been selected.
    But I cannot return value inside widgetSelected since it must be void.
    Then where to set AquiferStr = the updated items after selectionlistener is threw such as combo.getItem(combo.getSelectionIndex())

    //return changes items in combo2
    int rowNum=2;
    String[][]AquiferStr=new String[rowNum][rowNum];
    for (int i = 0; i < rowNum; i++) {
    //ERROR IN SAVE. Without widgetSelected CANNOT RETURN combo2.getItem(combo.getSelectionIndex())
    AquiferStr[i][0] = combo2.getItem(i);
    AquiferStr[i][1] = (String)combo2.getText();
    //AquiferStr[i][1] = (String) combo2.getItem(combo.getSelectionIndex());
    System.out.println("save int getItem"+combo2.getItem(i));
    return AquiferStr;

    I made my code based on this original snippet
    Sample Combo : ComboSWT JFace EclipseJava

    The snapshot looks like this
    My code is also attached.

    Many thanks!
