-.SH DESCRIPTION
-The QPtrListIterator class provides an iterator for QPtrList collections.
-.PP
-Define a template instance QPtrListIterator<X> to create a list iterator that operates on QPtrList<X> (list of X*).
-.PP
-The following example is similar to the example in the QPtrList class documentation, but it uses QPtrListIterator. The class Employee is defined there.
-.PP
-.nf
-.br
- QPtrList<Employee> list;
-.br
-.br
- list.append( new Employee("John", "Doe", 50000) );
-.br
- list.append( new Employee("Jane", "Williams", 80000) );
-.br
- list.append( new Employee("Tom", "Jones", 60000) );
-.br
-.br
- QPtrListIterator<Employee> it( list );
-.br
- Employee *employee;
-.br
- while ( (employee = it.current()) != 0 ) {
-.br
- ++it;
-.br
- cout << employee->surname().latin1() << ", " <<
-.br
- employee->forename().latin1() << " earns " <<
-.br
- employee->salary() << endl;
-.br
- }
-.br
-.fi
-.PP
-The output is
-.PP
-.nf
-.br
- Doe, John earns 50000
-.br
- Williams, Jane earns 80000
-.br
- Jones, Tom earns 60000
-.br
-.fi
-.PP
-Using a list iterator is a more robust way of traversing the list than using the QPtrList member functions first(), next(), current(), etc., as many iterators can traverse the same list independently.
-.PP
-An iterator has its own current list item and can get the next and previous list items. It doesn't modify the list in any way.
-.PP
-When an item is removed from the list, all iterators that point to that item are updated to point to QPtrList::current() instead to avoid dangling references.
-.PP
-See also QPtrList, Collection Classes, and Non-GUI Classes.
-.SH MEMBER FUNCTION DOCUMENTATION
-.SH "QPtrListIterator::QPtrListIterator ( const QPtrList<type> & list )"
-Constructs an iterator for \fIlist\fR. The current iterator item is set to point on the first item in the \fIlist\fR.
-.SH "QPtrListIterator::~QPtrListIterator ()"
-Destroys the iterator.
-.SH "bool QPtrListIterator::atFirst () const"
-Returns TRUE if the current iterator item is the first list item; otherwise returns FALSE.
-.PP
-See also toFirst() and atLast().
-.SH "bool QPtrListIterator::atLast () const"
-Returns TRUE if the current iterator item is the last list item; otherwise returns FALSE.
-.PP
-See also toLast() and atFirst().
-.SH "uint QPtrListIterator::count () const"
-Returns the number of items in the list this iterator operates on.
-.PP
-See also isEmpty().
-.PP
-Example: customlayout/card.cpp.
-.SH "type * QPtrListIterator::current () const"
-Returns a pointer to the current iterator item. If the iterator is positioned before the first item in the list or after the last item in the list, 0 is returned.
-.PP
-Examples:
-.)l canvas/canvas.cpp, customlayout/card.cpp, and customlayout/flow.cpp.
-.SH "bool QPtrListIterator::isEmpty () const"
-Returns TRUE if the list is empty; otherwise returns FALSE.
-.PP
-See also count().
-.SH "QPtrListIterator::operator type * () const"
-Cast operator. Returns a pointer to the current iterator item. Same as current().
-.SH "type * QPtrListIterator::operator() ()"
-Makes the succeeding item current and returns the original current item.
-.PP
-If the current iterator item was the last item in the list or if it was 0, 0 is returned.
-.SH "type * QPtrListIterator::operator* ()"
-Asterisk operator. Returns a pointer to the current iterator item. Same as current().
-.SH "type * QPtrListIterator::operator++ ()"
-Prefix ++ makes the succeeding item current and returns the new current item.
-.PP
-If the current iterator item was the last item in the list or if it was 0, 0 is returned.
-.SH "type * QPtrListIterator::operator+= ( uint jump )"
-Sets the current item to the item \fIjump\fR positions after the current item and returns a pointer to that item.
-.PP
-If that item is beyond the last item or if the list is empty, it sets the current item to 0 and returns 0
-.SH "type * QPtrListIterator::operator-- ()"
-Prefix - makes the preceding item current and returns the new current item.
-.PP
-If the current iterator item was the first item in the list or if it was 0, 0 is returned.
-.SH "type * QPtrListIterator::operator-= ( uint jump )"
-Returns the item \fIjump\fR positions before the current item or 0 if it is beyond the first item. Makes this the current item.
-.SH "QPtrListIterator<type> & QPtrListIterator::operator= ( const QPtrListIterator<type> & it )"
-Assignment. Makes a copy of the iterator \fIit\fR and returns a reference to this iterator.
-.SH "type * QPtrListIterator::toFirst ()"
-Sets the current iterator item to point to the first list item and returns a pointer to the item. Sets the current item to 0 and returns 0 if the list is empty.
-.PP
-See also toLast() and atFirst().
-.SH "type * QPtrListIterator::toLast ()"
-Sets the current iterator item to point to the last list item and returns a pointer to the item. Sets the current item to 0 and returns 0 if the list is empty.
-.PP
-See also toFirst() and atLast().
