I'm developing a BlackBerry 10 mobile application using the Momentics IDE (native SDK).
I have a listview which I want to handle its items click with C++ (I need to use C++ not QML).
I can get the index path using the "connect" instruction, but I have problem with parsing a QVariant to a custom class ;
Q_ASSERT(QObject::connect(list1, SIGNAL(triggered(QVariantList)), this, SLOT(openSheet(QVariantList))));
QVariant selectItem = m_categoriesListDataModel->data(indexPath);
I tried to use the static cast like below
Category* custType = static_cast<Category*>(selectItem);
but it returns :
"invalid static_cast from type 'QVariant' to type 'Category*'"
Can anyone help me on this ?
EDIT: works for non QObject derived type (see Final Contest's answer for this case)
First of all, you need to register your type to be part of QVariant managed types
//customtype.h
class CustomType {
};
Q_DECLARE_METATYPE(CustomType)
Then you can retrieve your custom type from QVariant
in this way :
CustomType ct = myVariant.value<CustomType>();
which is equivalent to:
CustomType ct = qvariant_cast<CustomType>(myVariant);
