You could use the following code:
QList<int> list = QList<int>() << 1 << 1;
or initializer list with C++11:
QList<int> list({1, 1});
You can enable the latter with the -std=c++0x or -std=c++11 option for gcc. You will also need the relevant Qt version for that where initializer list support has been added to the QList constructor.
