This copying may be an expensive operation, so std::vector should be used judiciously. +You can also create a list-like data structure by constructing a QJSValue using +QJSEngine::newArray(). Such a JavaScript array does not need any conversion +when passing it between QML and C++. See \l{QJSValue#Working With Arrays} for +details on how to manipulate JavaScript arrays from C++. + Other sequence types are not supported transparently, and instead an instance of any other sequence type will be passed between QML and C++ as an opaque QVariantList. |
