Define a template -instance TQAsciiDict<X> to create a dictionary that operates on -pointers to X (X*). -<p> A dictionary is a collection of key-value pairs. The key is a -char* used for insertion, removal and lookup. The value is a -pointer. Dictionaries provide very fast insertion and lookup. -<p> TQAsciiDict cannot handle Unicode keys; use the <a href="ntqdict.html">TQDict</a> template -instead, which uses <a href="tqstring.html">TQString</a> keys. A TQDict has the same -performace as a TQAsciiDict. -<p> Example: -<pre> - TQAsciiDict<TQLineEdit> fields; // char* keys, TQLineEdit* values - fields.<a href="#insert">insert</a>( "forename", new <a href="ntqlineedit.html">TQLineEdit</a>( this ) ); - fields.<a href="#insert">insert</a>( "surname", new <a href="ntqlineedit.html">TQLineEdit</a>( this ) ); - - fields["forename"]->setText( "Homer" ); - fields["surname"]->setText( "Simpson" ); - - <a href="qasciidictiterator.html">TQAsciiDictIterator</a><TQLineEdit> it( fields ); // See TQAsciiDictIterator - for( ; it.<a href="qasciidictiterator.html#current">current</a>(); ++it ) - cout << it.<a href="qasciidictiterator.html#currentKey">currentKey</a>() << ": " << it.<a href="qasciidictiterator.html#current">current</a>()->text() << endl; - cout << endl; - - if ( fields["forename"] && fields["surname"] ) - cout << fields["forename"]->text() << " " - << fields["surname"]->text() << endl; // Prints "Homer Simpson" - - fields.<a href="#remove">remove</a>( "forename" ); // Does not delete the line edit - if ( ! fields["forename"] ) - cout << "forename is not in the dictionary" << endl; - </pre> - -In this example we use a dictionary to keep track of the line -edits we're using. We insert each line edit into the dictionary -with a unique name and then access the line edits via the -dictionary. See <a href="tqptrdict.html">TQPtrDict</a>, <a href="ntqintdict.html">TQIntDict</a> and <a href="ntqdict.html">TQDict</a>. -<p> See TQDict for full details, including the choice of dictionary -size, and how deletions are handled. -<p> <p>See also <a href="qasciidictiterator.html">TQAsciiDictIterator</a>, <a href="ntqdict.html">TQDict</a>, <a href="ntqintdict.html">TQIntDict</a>, <a href="tqptrdict.html">TQPtrDict</a>, <a href="collection.html">Collection Classes</a>, <a href="collection.html">Collection Classes</a>, and <a href="tools.html">Non-GUI Classes</a>. - -<hr><h2>Member Function Documentation</h2> -<h3 class=fn><a name="TQAsciiDict"></a>TQAsciiDict::TQAsciiDict ( int size = 17, bool caseSensitive = TRUE, bool copyKeys = TRUE ) -</h3> - -<p> Constructs a dictionary optimized for less than <em>size</em> entries. -<p> We recommend setting <em>size</em> to a suitably large <a href="primes.html#prime">prime</a> number (a -bit larger than the expected number of entries). This makes the -hash distribution better and will improve lookup performance. -<p> When <em>caseSensitive</em> is TRUE (the default) TQAsciiDict treats -"abc" and "Abc" as different keys; when it is FALSE "abc" and -"Abc" are the same. Case-insensitive comparison only considers the -26 letters in US-ASCII. -<p> If <em>copyKeys</em> is TRUE (the default), the dictionary copies keys -using strcpy(); if it is FALSE, the dictionary just copies the -pointers. - -<h3 class=fn><a name="TQAsciiDict-2"></a>TQAsciiDict::TQAsciiDict ( const <a href="ntqasciidict.html">TQAsciiDict</a><type> & dict ) -</h3> - -<p> Constructs a copy of <em>dict</em>. -<p> Each item in <em>dict</em> is inserted into this dictionary.
