-The TQAsciiDict class is a template class that provides a dictionary based on char* keys.
-<p>
-
-<p>
-<p> TQAsciiDict is implemented as a template class. Define a template
-instance TQAsciiDict&lt;X&gt; 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&lt;TQLineEdit&gt; 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"]-&gt;setText( "Homer" );
- fields["surname"]-&gt;setText( "Simpson" );
-
- <a href="qasciidictiterator.html">TQAsciiDictIterator</a>&lt;TQLineEdit&gt; it( fields ); // See TQAsciiDictIterator
- for( ; it.<a href="qasciidictiterator.html#current">current</a>(); ++it )
- cout &lt;&lt; it.<a href="qasciidictiterator.html#currentKey">currentKey</a>() &lt;&lt; ": " &lt;&lt; it.<a href="qasciidictiterator.html#current">current</a>()-&gt;text() &lt;&lt; endl;
- cout &lt;&lt; endl;
-
- if ( fields["forename"] &amp;&amp; fields["surname"] )
- cout &lt;&lt; fields["forename"]-&gt;text() &lt;&lt; " "
- &lt;&lt; fields["surname"]-&gt;text() &lt;&lt; endl; // Prints "Homer Simpson"
-
- fields.<a href="#remove">remove</a>( "forename" ); // Does not delete the line edit
- if ( ! fields["forename"] )
- cout &lt;&lt; "forename is not in the dictionary" &lt;&lt; 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>.

-<h3 class=fn><a name="TQAsciiDict"></a>TQAsciiDict::TQAsciiDict ( int&nbsp;size = 17, bool&nbsp;caseSensitive = TRUE, bool&nbsp;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&nbsp;<a href="ntqasciidict.html">TQAsciiDict</a>&lt;type&gt;&nbsp;&amp;&nbsp;dict )
-</h3>
-
-<p> Constructs a copy of <em>dict</em>.
-<p> Each item in <em>dict</em> is inserted into this dictionary. Only the
-pointers are copied (shallow copy).
-
-<h3 class=fn><a name="~TQAsciiDict"></a>TQAsciiDict::~TQAsciiDict ()
-</h3>
-
-<p> Removes all items from the dictionary and destroys it.
-<p> The items are deleted if auto-delete is enabled.
-<p> All iterators that access this dictionary will be reset.
-<p> <p>See also <a href="tqptrcollection.html#setAutoDelete">setAutoDelete</a>().
-
-<h3 class=fn>bool <a name="autoDelete"></a>TQPtrCollection::autoDelete () const
-</h3>
-
-<p> Returns the setting of the auto-delete option. The default is FALSE.
-<p> <p>See also <a href="tqptrcollection.html#setAutoDelete">setAutoDelete</a>().
-
-<h3 class=fn>void <a name="clear"></a>TQAsciiDict::clear ()<tt> [virtual]</tt>
-</h3>
-
-<p> Removes all items from the dictionary.
-<p> The removed items are deleted if <a href="tqptrcollection.html#setAutoDelete">auto-deletion</a> is enabled.
-<p> All dictionary iterators that operate on dictionary are reset.
-<p> <p>See also <a href="#remove">remove</a>(), <a href="#take">take</a>(), and <a href="tqptrcollection.html#setAutoDelete">setAutoDelete</a>().

-<h3 class=fn>type * <a name="find"></a>TQAsciiDict::find ( const&nbsp;char&nbsp;*&nbsp;key ) const
-</h3>
-
-<p> Returns the item associated with <em>key</em>, or 0 if the key does not
-exist in the dictionary.
-<p> This function uses an internal hashing algorithm to optimize
-lookup.
-<p> If there are two or more items with equal keys, then the item that
-was most recently inserted will be found.
-<p> Equivalent to the [] operator.
-<p> <p>See also <a href="#operator[]">operator[]</a>().
-
-<h3 class=fn>void <a name="insert"></a>TQAsciiDict::insert ( const&nbsp;char&nbsp;*&nbsp;key, const&nbsp;type&nbsp;*&nbsp;item )
-</h3>
-
-<p> Inserts the <em>key</em> with the <em>item</em> into the dictionary.
-<p> Multiple items can have the same key, in which case only the last
-item will be accessible using <a href="#operator[]">operator[]</a>().
-<p> <em>item</em> may not be 0.
-<p> <p>See also <a href="#replace">replace</a>().
-
-<h3 class=fn>bool <a name="isEmpty"></a>TQAsciiDict::isEmpty () const
-</h3>
-
-<p> Returns TRUE if the dictionary is empty, i.e. <a href="#count">count</a>() == 0;
-otherwise it returns FALSE.
-<p> <p>See also <a href="#count">count</a>().

-<h3 class=fn><a href="ntqasciidict.html">TQAsciiDict</a>&lt;type&gt;&nbsp;&amp; <a name="operator-eq"></a>TQAsciiDict::operator= ( const&nbsp;<a href="ntqasciidict.html">TQAsciiDict</a>&lt;type&gt;&nbsp;&amp;&nbsp;dict )
-</h3>
-
-<p> Assigns <em>dict</em> to this dictionary and returns a reference to this
-dictionary.
-<p> This dictionary is first cleared and then each item in <em>dict</em> is
-inserted into this dictionary. Only the pointers are copied
-(shallow copy) unless <a href="tqptrcollection.html#newItem">newItem</a>() has been reimplemented().
-
-<h3 class=fn>type * <a name="operator[]"></a>TQAsciiDict::operator[] ( const&nbsp;char&nbsp;*&nbsp;key ) const
-</h3>
-
-<p> Returns the item associated with <em>key</em>, or 0 if the key does
-not exist in the dictionary.
-<p> This function uses an internal hashing algorithm to optimize
-lookup.
-<p> If there are two or more items with equal keys, then the item that
-was most recently inserted will be found.
-<p> Equivalent to the <a href="#find">find</a>() function.
-<p> <p>See also <a href="#find">find</a>().
-
-<h3 class=fn><a href="ntqdatastream.html">TQDataStream</a>&nbsp;&amp; <a name="read"></a>TQAsciiDict::read ( <a href="ntqdatastream.html">TQDataStream</a>&nbsp;&amp;&nbsp;s, <a href="tqptrcollection.html#Item">TQPtrCollection::Item</a>&nbsp;&amp;&nbsp;item )<tt> [virtual protected]</tt>
-</h3>
-
-<p> Reads a dictionary item from the stream <em>s</em> and returns a
-reference to the stream.
-<p> The default implementation sets <em>item</em> to 0.
-<p> <p>See also <a href="#write">write</a>().
-
-<h3 class=fn>bool <a name="remove"></a>TQAsciiDict::remove ( const&nbsp;char&nbsp;*&nbsp;key )
-</h3>
-
-<p> Removes the item associated with <em>key</em> from the dictionary.
-Returns TRUE if successful, i.e. if the key existed in the
-dictionary; otherwise returns FALSE.
-<p> If there are two or more items with equal keys, then the most
-recently inserted item will be removed.
-<p> The removed item is deleted if <a href="tqptrcollection.html#setAutoDelete">auto-deletion</a> is enabled.
-<p> All dictionary iterators that refer to the removed item will be
-set to point to the next item in the dictionary traversal order.
-<p> <p>See also <a href="#take">take</a>(), <a href="#clear">clear</a>(), and <a href="tqptrcollection.html#setAutoDelete">setAutoDelete</a>().
-
-<h3 class=fn>void <a name="replace"></a>TQAsciiDict::replace ( const&nbsp;char&nbsp;*&nbsp;key, const&nbsp;type&nbsp;*&nbsp;item )
-</h3>
-
-<p> Replaces an item that has a key equal to <em>key</em> with <em>item</em>.
-<p> If the item does not already exist, it will be inserted.
-<p> <em>item</em> may not be 0.
-<p> Equivalent to:
-<pre>
- TQAsciiDict&lt;char&gt; dict;
- ...
- if ( dict.<a href="#find">find</a>(key) )
- dict.<a href="#remove">remove</a>( key );
- dict.<a href="#insert">insert</a>( key, item );
- </pre>
-
-<p> If there are two or more items with equal keys, then the most
-recently inserted item will be replaced.
-<p> <p>See also <a href="#insert">insert</a>().
-
-<h3 class=fn>void <a name="resize"></a>TQAsciiDict::resize ( uint&nbsp;newsize )
-</h3>
-
-<p> Changes the size of the hashtable to <em>newsize</em>. The contents of
-the dictionary are preserved but all iterators on the dictionary
-become invalid.
-
-<h3 class=fn>void <a name="setAutoDelete"></a>TQPtrCollection::setAutoDelete ( bool&nbsp;enable )
-</h3>
-
-<p> Sets the collection to auto-delete its contents if <em>enable</em> is
-TRUE and to never delete them if <em>enable</em> is FALSE.
-<p> If auto-deleting is turned on, all the items in a collection are
-deleted when the collection itself is deleted. This is convenient
-if the collection has the only pointer to the items.
-<p> The default setting is FALSE, for safety. If you turn it on, be
-careful about copying the collection - you might find yourself
-with two collections deleting the same items.
-<p> Note that the auto-delete setting may also affect other functions
-in subclasses. For example, a subclass that has a <a href="#remove">remove</a>()
-function will remove the item from its data structure, and if
-auto-delete is enabled, will also delete the item.
-<p> <p>See also <a href="tqptrcollection.html#autoDelete">autoDelete</a>().

-<h3 class=fn>uint <a name="size"></a>TQAsciiDict::size () const
-</h3>
-
-<p> Returns the size of the internal hash array (as specified in the
-constructor).

-distribution using <a href="ntqapplication.html#qDebug">tqDebug</a>().
-
-<h3 class=fn>type * <a name="take"></a>TQAsciiDict::take ( const&nbsp;char&nbsp;*&nbsp;key )
-</h3>
-
-<p> Takes the item associated with <em>key</em> out of the dictionary
-without deleting it (even if <a href="tqptrcollection.html#setAutoDelete">auto-deletion</a> is enabled).
-<p> If there are two or more items with equal keys, then the most
-recently inserted item will be taken.
-<p> Returns a pointer to the item taken out, or 0 if the key does not
-exist in the dictionary.
-<p> All dictionary iterators that refer to the taken item will be set
-to point to the next item in the dictionary traversal order.
