DESCRIPTION

25       The QIntDictIterator class provides an iterator for QIntDict
26       collections.
27
28       QIntDictIterator is implemented as a template class. Define a template
29       instance QIntDictIterator<X> to create a dictionary iterator that
30       operates on QIntDict<X> (dictionary of X*).
31
32       Example:
33
34           QIntDict<QLineEdit> fields;
35           for ( int i = 0; i < 3; i++ )
36               fields.insert( i, new QLineEdit( this ) );
37           fields[0]->setText( "Homer" );
38           fields[1]->setText( "Simpson" );
39           fields[2]->setText( "45" );
40           QIntDictIterator<QLineEdit> it( fields );
41           for ( ; it.current(); ++it )
42               cout << it.currentKey() << ": " << it.current()->text() << endl;
43           // Output (random order):
44           //  0: Homer
45           //  1: Simpson
46           //  2: 45
47
48       Note that the traversal order is arbitrary; you are not guaranteed the
49       order shown above.
50
51       Multiple iterators may independently traverse the same dictionary. A
52       QIntDict knows about all the iterators that are operating on the
53       dictionary. When an item is removed from the dictionary, QIntDict
54       updates all iterators that refer the removed item to point to the next
55       item in the traversal order.

MEMBER FUNCTION DOCUMENTATION

QIntDictIterator::QIntDictIterator ( const QIntDict<type> & dict )

61       Constructs an iterator for dict. The current iterator item is set to
62       point to the 'first' item in the dict. The first item refers to the
63       first item in the dictionary's arbitrary internal ordering.
64

QIntDictIterator::~QIntDictIterator ()

66       Destroys the iterator.
67

uint QIntDictIterator::count () const

69       Returns the number of items in the dictionary this iterator operates
70       over.
71
72       See also isEmpty().
73

type * QIntDictIterator::current () const

75       Returns a pointer to the current iterator item.
76

long QIntDictIterator::currentKey () const

78       Returns the key for the current iterator item.
79

bool QIntDictIterator::isEmpty () const

81       Returns TRUE if the dictionary is empty; otherwise eturns FALSE.
82
83       See also count().
84

QIntDictIterator::operator type * () const

86       Cast operator. Returns a pointer to the current iterator item. Same as
87       current().
88

type * QIntDictIterator::operator() ()

90       Makes the succeeding item current and returns the original current
91       item.
92
93       If the current iterator item was the last item in the dictionary or if
94       it was 0, 0 is returned.
95

type * QIntDictIterator::operator++ ()

97       Prefix ++ makes the succeeding item current and returns the new current
98       item.
99
100       If the current iterator item was the last item in the dictionary or if
101       it was 0, 0 is returned.
102

type * QIntDictIterator::operator+= ( uint jump )

104       Sets the current item to the item jump positions after the current
105       item, and returns a pointer to that item.
106
107       If that item is beyond the last item or if the dictionary is empty, it
108       sets the current item to 0 and returns 0.
109

type * QIntDictIterator::toFirst ()

111       Sets the current iterator item to point to the first item in the
112       dictionary and returns a pointer to the item. The first item refers to
113       the first item in the dictionary's arbitrary internal ordering. If the
114       dictionary is  empty it sets the current item to 0 and returns 0.
