Define a +template instance QIntDictIterator<X> to create a dictionary +iterator that operates on QIntDict<X> (dictionary of X*). +<p> Example: +<pre> + <a href="qintdict.html">QIntDict</a><QLineEdit> fields; + for ( int i = 0; i < 3; i++ ) + fields.<a href="qintdict.html#insert">insert</a>( i, new <a href="qlineedit.html">QLineEdit</a>( this ) ); + + fields[0]->setText( "Homer" ); + fields[1]->setText( "Simpson" ); + fields[2]->setText( "45" ); + + QIntDictIterator<QLineEdit> it( fields ); + for ( ; it.<a href="#current">current</a>(); ++it ) + cout << it.<a href="#currentKey">currentKey</a>() << ": " << it.<a href="#current">current</a>()->text() << endl; + + // Output (random order): + // 0: Homer + // 1: Simpson + // 2: 45 + </pre> + +<p> Note that the traversal order is arbitrary; you are not guaranteed the +order shown above. +<p> Multiple iterators may independently traverse the same dictionary. +A <a href="qintdict.html">QIntDict</a> knows about all the iterators that are operating on the +dictionary.
