Detailed Description

The QGList class is an internal class for implementing Qt collection classes.

QGList is a strictly internal class that acts as a base class for several collection classes; QList, QQueue and QStack.

QGList has some virtual functions that can be reimplemented to customize the subclasses.

Normally, you do not have to reimplement any of these functions. If you still want to reimplement them, see the QStrList class (qstrlist.h), which is a good example.

QGList::QGList () [protected]

QGList::QGList ( const QGList & list ) [protected]

For internal use only.

QGList::~QGList () [protected]

For internal use only.

void QGList::append ( GCI d ) [protected]

For internal use only.

GCI QGList::at ( uint index ) [protected]

For internal use only.

int QGList::at () const [protected]

GCI QGList::cfirst () const [protected]

GCI QGList::clast () const [protected]

void QGList::clear () [virtual protected]

For internal use only.

Reimplemented from QCollection.

int QGList::compareItems ( GCI item1, GCI item2 ) [virtual protected]

This virtual function compares two list items.

Returns:

This function returns int rather than bool so that reimplementations can return three values and use it to sort by:

The QList::inSort() function requires that compareItems() is implemented as described here.

This function should not modify the list because some const functions call compareItems().

The default implementation compares the pointers:


uint QGList::contains ( GCI d ) const [protected]

For internal use only.

uint QGList::containsRef ( GCI d ) const [protected]

For internal use only.

uint QGList::count () const [virtual]

For internal use only.

Reimplemented from QCollection.

For internal use only.

int QGList::find ( GCI d, bool fromStart = TRUE ) [protected]

For internal use only.

int QGList::findRef ( GCI d, bool fromStart = TRUE ) [protected]

For internal use only.

GCI QGList::first () [protected]

For internal use only.

GCI QGList::get () const [protected]

For internal use only.

void QGList::inSort ( GCI d ) [protected]

For internal use only.

bool QGList::insertAt ( uint index, GCI d ) [protected]

GCI QGList::last () [protected]

QDataStream & QGList::read ( QDataStream & s )

For internal use only.

QDataStream & QGList::read ( QDataStream & s, GCI & item ) [virtual protected]

Reads a collection/list item from the stream s and returns a reference to the stream.

The default implementation sets item to 0.

For internal use only.

QDataStream & QGList::write ( QDataStream & s, GCI ) const [virtual protected]

Writes a collection/list item to the stream s and returns a reference to the stream.

The default implementation does nothing.
