◆ QByteArrayList

Definition at line 36 of file qcontainerfwd.h.

◆ QPair

template<typename T1 , typename T2 >
using QPair = std::pair<T1, T2>

Definition at line 25 of file qcontainerfwd.h.

◆ QStringList

QStringList::QStringList

Constructs a string list that contains the given string, str.

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Constructs a copy of other.

Longer lists are easily created like this:

QStringList longerList = (QStringList() << str1 << str2 << str3);
\inmodule QtCore

append()

This operation takes \l{constant time}, because QStringList is \l{implicitly shared}. This makes returning a QStringList from a function very fast. If a shared instance is modified, it will be copied (copy-on-write), and that takes \l{linear time}.

Move-constructs from QList<QString>.

After a successful construction, other will be empty.
