Qt 3 Support Members for QLinkedList
The following class members are part of the Qt 3 support layer. They are provided to help you port old code to Qt 4. We advise against using them in new code.
Public Functions

iterator | find ( const T & t ) |
const_iterator | find ( const_iterator from, const T & t ) const |
const_iterator | find ( const T & t ) const |
int | findIndex ( const T & t ) const |
iterator | remove ( iterator pos ) |
Member Function Documentation
iterator QLinkedList::find ( iterator from, const T & t )
If you need random access to a data structure then QList, QVector, QMap, or QHash, are all better choices than QLinkedList.
For example, if you have code like
QLinkedList::iterator i = list->find(from, value);
you can rewrite it as
QLinkedList::iterator i = from;
while (i != list->end() && *i != value)
++i;
iterator QLinkedList::find ( const T & t )
If you need random access to a data structure then QList, QVector, QMap, or QHash, are all better choices than QLinkedList.
For example, if you have code like
QLinkedList::iterator i = list->find(value);
you can rewrite it as
QLinkedList::iterator i = list->begin();
while (i != list->end() && *i != value)
++i;
If you need random access to a data structure then QList, QVector, QMap, or QHash, are all better choices than QLinkedList.
For example, if you have code like
QLinkedList::const_iterator i = list->find(from, value);
you can rewrite it as
QLinkedList::const_iterator i = from;
while (i != list->end() && *i != value)
++i;
const_iterator QLinkedList::find ( const T & t ) const
If you need random access to a data structure then QList, QVector, QMap, or QHash, are all better choices than QLinkedList.
For example, if you have code like
QLinkedList::const_iterator i = list->find(value);
you can rewrite it as
QLinkedList::const_iterator i = list->begin();
while (i != list->end() && *i != value)
++i;
int QLinkedList::findIndex ( const T & t ) const
If you need indexes then QList or QVector are better choices than QLinkedList.
For example, if you have code like
int index = list->findIndex(value);
you can rewrite it as
int index = 0;
bool found = false;
for (const_iterator i = list->begin(); i != list->end(); ++i; ++index)
if (*i == value) {
found = true;
break;
}
if (!found)
index = -1;
Use erase() instead.
