How to get list results from QVariant

[RuoyanMeng]

Hi, I am using pythonQt to embed python code in my C++ code, I create a python function as the example did, but my return value is a list, and I couldn't fetch the list value after calling the function
context.evalScript("def multiply(a,b):\n return [a,b];\n");
QVariantList args;
args << 42 << 47;
QVariant result = context.call("multiply", args);

Could you give some idea on how to get the result when the return value is a list?

QVariantList resultList = result.toList();
int a = resultList[0].toInt();
int b = resultList[1].toInt();

This is without any type checking, but I guess the important part is the toList() method. Simply have a look at the interface of QVariant.

Thank you so much! I tried the toList method before, but I didn't notice that toInt() is needed to extract the corresponding data type value.
