completions based on an item
model.</p>
<p>You can use QCompleter to provide auto completions in any Qt
widget, such as <a href="qlineedit.html">QLineEdit</a> and <a href="qcombobox.html">QComboBox</a>. When the user starts typing a word,
QCompleter suggests possible ways of completing the word, based on
a word list. The word list is provided as a <a href="qabstractitemmodel.html">QAbstractItemModel</a>. (For simple
applications, where the word list is static, you can pass a
<a href="qstringlist.html">QStringList</a> to QCompleter's
constructor.)</p>
<a id="basic-usage" name="basic-usage" />
<h3>Basic Usage</h3>
<p>A QCompleter is used typically with a <a href="qlineedit.html">QLineEdit</a> or <a href="qcombobox.html">QComboBox</a>. For example, here's how to provide
auto completions from a simple word list in a <a href="qlineedit.html">QLineEdit</a>:</p>
<pre class="cpp">
<span class="type"><a href="qstringlist.html">QStringList</a></span> wordList;
wordList <span class="operator"><</span><span class="operator"><</span> <span class="string">"alpha"</span> <span class="operator"><</span><span class="operator"><</span> <span class="string">"omega"</span> <span class="operator"><</span><span class="operator"><</span> <span class="string">"omicron"</span> <span class="operator"><</span><span class="operator"><</span> <span class="string">"zeta"</span>;
<span class="type"><a href="qlineedit.html">QLineEdit</a></span> <span class="operator">*</span>lineEdit <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qlineedit.html">QLineEdit</a></span>(<span class="keyword">this</span>);
<span class="type">QCompleter</span> <span class="operator">*</span>completer <span class="operator">=</span> <span class="keyword">new</span> <span class="type">QCompleter</span>(wordList<span class="operator">,</span> <span class="keyword">this</span>);
completer<span class="operator">-</span><span class="operator">></span><a href="qcompleter.html#caseSensitivity-prop">setCaseSensitivity</a>(<span class="type"><a href="qt.html">Qt</a></span><span class="operator">.</span>CaseInsensitive);
lineEdit<span class="operator">-</span><span class="operator">></span>setCompleter(completer);
</pre>
<p>A <a href="qfilesystemmodel.html">QFileSystemModel</a> can be
used to provide auto completion of file names. For example:</p>
<pre class="cpp">
<span class="type">QCompleter</span> <span class="operator">*</span>completer <span class="operator">=</span> <span class="keyword">new</span> <span class="type">QCompleter</span>(<span class="keyword">this</span>);
completer<span class="operator">-</span><span class="operator">></span><a href="qcompleter.html#setModel">setModel</a>(<span class="keyword">new</span> <span class="type"><a href="qdirmodel.html">QDirModel</a></span>(completer));
lineEdit<span class="operator">-</span><span class="operator">></span>setCompleter(completer);
</pre>
<p>To set the model on which QCompleter should operate, call
<a href="qcompleter.html#setModel">setModel</a>(). By default,
QCompleter will attempt to match the <a href="qcompleter.html#completionPrefix-prop">completion prefix</a>
(i.e., the word that the user has started typing) against the
<a href="qt.html#ItemDataRole-enum">Qt.EditRole</a> data stored in
column 0 in the model case sensitively. This can be changed using
<a href="qcompleter.html#completionRole-prop">setCompletionRole</a>(),
<a href="qcompleter.html#completionColumn-prop">setCompletionColumn</a>(),
and <a href="qcompleter.html#caseSensitivity-prop">setCaseSensitivity</a>().</p>
<p>If the model is sorted on the column and role that are used for
completion, you can call <a href="qcompleter.html#modelSorting-prop">setModelSorting</a>() with
either <a href="qcompleter.html#ModelSorting-enum">QCompleter.CaseSensitivelySortedModel</a>
or <a href="qcompleter.html#ModelSorting-enum">QCompleter.CaseInsensitivelySortedModel</a>
as the argument. On large models, this can lead to significant
performance improvements, because QCompleter can then use binary
search instead of linear search.</p>
<p>The model can be a <a href="qabstractlistmodel.html">list
model</a>, a <a href="qabstracttablemodel.html">table model</a>, or
a <a href="qabstractitemmodel.html">tree model</a>. Completion on
tree models is slightly more involved and is covered in the
<a href="#handling-tree-models">Handling Tree Models</a> section
below.</p>
<p>The <a href="qcompleter.html#completionMode-prop">completionMode</a>()
determines the mode used to provide completions to the user.</p>
<a id="iterating-through-completions" name="iterating-through-completions" />
<h3>Iterating Through Completions</h3>
<p>To retrieve a single candidate string, call <a href="qcompleter.html#completionPrefix-prop">setCompletionPrefix</a>()
with the text that needs to be completed and call <a href="qcompleter.html#currentCompletion">currentCompletion</a>(). You
can iterate through the list of completions as below:</p>
<pre class="cpp">
<span class="keyword">for</span> (<span class="type">int</span> i <span class="operator">=</span> <span class="number">0</span>; completer<span class="operator">-</span><span class="operator">></span>setCurrentRow(i); i<span class="operator">+</span><span class="operator">+</span>)
<a href="qtcore.html#qDebug">qDebug</a>() <span class="operator"><</span><span class="operator"><</span> completer<span class="operator">-</span><span class="operator">></span><a href="qcompleter.html#currentCompletion">currentCompletion</a>() <span class="operator"><</span><span class="operator"><</span> <span class="string">" is match number "</span> <span class="operator"><</span><span class="operator"><</span> i;
</pre>
<p><a href="qcompleter.html#completionCount">completionCount</a>()
returns the total number of completions for the current prefix.
<a href="qcompleter.html#completionCount">completionCount</a>()
should be avoided when possible, since it requires a scan of the
entire model.</p>
<a id="the-completion-model" name="the-completion-model" />
<h3>The Completion Model</h3>
<p><a href="qcompleter.html#completionModel">completionModel</a>()
return a list model that contains all possible completions for the
current completion prefix, in the order in which they appear in the
model. This model can be used to display the current completions in
a custom view. Calling <a href="qcompleter.html#completionPrefix-prop">setCompletionPrefix</a>()
automatically refreshes the completion model.</p>
<a id="handling-tree-models" name="handling-tree-models" />
<h3>Handling Tree Models</h3>
<p>QCompleter can look for completions in tree models, assuming
that any item (or sub-item or sub-sub-item) can be unambiguously
represented as a string by specifying the path to the item. The
completion is then performed one level at a time.</p>
<p>Let's take the example of a user typing in a file system path.
The model is a (hierarchical) <a href="qfilesystemmodel.html">QFileSystemModel</a>. The completion occurs
for every element in the path. For example, if the current text is
<tt>C:\Wind</tt>, QCompleter might suggest <tt>Windows</tt> to
complete the current path element. Similarly, if the current text
is <tt>C:\Windows\Sy</tt>, QCompleter might suggest
<tt>System</tt>.</p>
<p>For this kind of completion to work, QCompleter needs to be able
to split the path into a list of strings that are matched at each
level. For <tt>C:\Windows\Sy</tt>, it needs to be split as "C:",
"Windows" and "Sy". The default implementation of <a href="qcompleter.html#splitPath">splitPath</a>(), splits the <a href="qcompleter.html#completionPrefix-prop">completionPrefix</a> using
<a href="qdir.html#separator">QDir.separator</a>() if the model is
a <a href="qfilesystemmodel.html">QFileSystemModel</a>.</p>
<p>To provide completions, QCompleter needs to know the path from
an index. This is provided by <a href="qcompleter.html#pathFromIndex">pathFromIndex</a>(). The default
implementation of <a href="qcompleter.html#pathFromIndex">pathFromIndex</a>(), returns the
data for the <a href="qt.html#ItemDataRole-enum">edit role</a> for
list models and the absolute file path if the mode is a <a href="qfilesystemmodel.html">QFileSystemModel</a>.</p>
