Example #1

File: custompickerrecipe.cpp Project: 13natty/Cascades-Samples

CustomPickerRecipe::CustomPickerRecipe(Container *parent) :
        CustomControl(parent)
{
    bool connectResult;

    // A title label that will be updated depending on the picker selection.
    mDescription = Label::create("label");

    // A label to show the price
    mBill = Label::create("Bill:");

    // The custom picker its initiated in its expanded state.
    mPicker = Picker::create().title("Custom Pizza Picker").expanded(true);

    // An XMLModel is used for populating the different picker items, this
    // kind of data model is suitable for small lists with static content.
    XmlDataModel *pickerModel = new XmlDataModel(this);
    pickerModel->setSource(QUrl("models/custompickermodel.xml"));
    mPicker->setDataModel(pickerModel);

    // The items in the picker columns are created and handled by an PickerItemProvider,
    // see customprovider.h/cpp for details.
    CustomItemProvider *itemProvider = new CustomItemProvider(this, mPicker->dataModel());
    mPicker->setPickerItemProvider(itemProvider);

    // Finally the picker signal is connected to a slot function, so the title label
    // text can be set according to the selection in the picker.
    connectResult = connect(mPicker, SIGNAL(selectedValueChanged(const QVariant )),
                                     SLOT(onValueChanged(const QVariant )));

    // Add the label and the picker to the recipe Container.
    recipeContainer->add(mDescription);
    recipeContainer->add(mBill);
    recipeContainer->add(mPicker);

    setRoot(recipeContainer);
