What is the right way to initialize a QList?

Question

What is the right way to initialize QList? I want to make this code shorter:

QSplitter splitter; QList<int> list; list.append(1); list.append(1); splitter.setSizes(list); 

But when I use initialization from std::list, it doesn't seem be working:

splitter.setSizes(QList<int>::fromStdList(std::list<int>(1, 1))); 

In latter case, the splitter seems to divide in ratio 1:0.

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.
