How to dynamically populate IDropDownListController

Question

Hi!
My question is how can I dynamically populate the IDropDownListController widget? In the sample project WriteFishPrice the entries are all static, but I need to add or remove entries in the list. Thanks for any pointers!

Assuming you want to add inside a controller or an observer to you panel
Here's a function I use.
void MyDialogController::InitialiseDropdown(K2Vector<PMString> &stringArray, const WidgetID &widgetId)
    InterfacePtr<IPanelControlData> panelControlData(this, UseDefaultIID()); // i can get a Panelcontoldata because my controller is in the kDialogBoss
    if (panelControlData == nil)
        ASSERT_FAIL("panelControlData invalid");
    do
        IControlView* view = panelControlData->FindWidget(widgetId);
        if (view == nil)
            ASSERT_FAIL("control view invalid");
        InterfacePtr<IStringListControlData> stringListControlData(view, UseDefaultIID());
        if (stringListControlData == nil)
            ASSERT_FAIL("invalid stringListControlData");
            break;
        // Clear the drop down list.
        stringListControlData->Clear(
            kFalse, // don't invalidate.
            kFalse // don't notify
        // Add their names to the drop down.
        K2Vector <PMString>::iterator iter;
        for (iter = stringArray.begin(); iter < stringArray.end(); iter++)
            PMString server = *iter;
            server.SetTranslatable(kFalse);
            stringListControlData->AddString
                server,
                IStringListControlData::kEnd,
                kFalse, // don't invalidate.
                kFalse //don't notify.
        view->Invalidate();
    while(false);
