Struct qt_core::QStringList

The QStringList class provides a list of strings.

QStringList inherits from QList<QString>. Like QList, QStringList is implicitly shared. It provides fast index-based access as well as fast insertions and removals. Passing string lists as value parameters is both fast and safe.

All of QList's functionality also applies to QStringList. For example, you can use isEmpty() to test whether the list is empty, and you can call functions like append(), prepend(), insert(), replace(), removeAll(), removeAt(), removeFirst(), removeLast(), and removeOne() to modify a QStringList. In addition, QStringList provides a few convenience functions that make handling lists of strings easier:

Implementations§

See also operator=().

pub unsafe fn new_copy( other: impl CastInto<Ref<QStringList>> ) -> CppBox<QStringList>

The QStringList class provides a list of strings.

Calls C++ function: [constructor] void QStringList::QStringList(const QStringList& other).

The QStringList class provides a list of strings.

QStringList inherits from QList<QString>. Like QList, QStringList is implicitly shared. It provides fast index-based access as well as fast insertions and removals. Passing string lists as value parameters is both fast and safe.

All of QList's functionality also applies to QStringList. For example, you can use isEmpty() to test whether the list is empty, and you can call functions like append(), prepend(), insert(), replace(), removeAll(), removeAt(), removeFirst(), removeLast(), and removeOne() to modify a QStringList. In addition, QStringList provides a few convenience functions that make handling lists of strings easier:

Methods from Deref<Target = QListOfQString>§

pub unsafe fn add_assign_q_list_of_q_string( &self, l: impl CastInto<Ref<QListOfQString>> ) -> Ref<QListOfQString>

Calls C++ function: QList<QString>& QList<QString>::operator+=(const QList<QString>& l).

Appends the items of the other list to this list and returns a reference to this list.

See also operator+() and append().

pub unsafe fn add_assign_q_string( &self, t: impl CastInto<Ref<QString>> ) -> Ref<QListOfQString>

This is an overloaded function.

Calls C++ function: QList<QString>& QList<QString>::operator+=(const QString& t).

This is an overloaded function.

Appends value to the list.

See also append() and operator<<().

pub unsafe fn append_q_string(&self, t: impl CastInto<Ref<QString>>)

Inserts value at the end of the list.

Calls C++ function: void QList<QString>::append(const QString& t).

Inserts value at the end of the list.

Example:

QList<QString> list;
list.append(“one”);
list.append(“two”);
list.append(“three”);
// list: [“one”, “two”, “three”]

This is the same as list.insert(size(), value).

If this list is not shared, this operation is typically very fast (amortized constant time), because QList preallocates extra space on both sides of its internal buffer to allow for fast growth at both ends of the list.

See also operator<<(), prepend(), and insert().
