Description</h2> <p>The <a href="qstringlist.html">QStringList</a> class provides a list of strings.</p> <p><a href="qstringlist.html">QStringList</a> inherits from <a href="qlist.html">QList</a><<a href="qstring.html">QString</a>>. Like <a href="qlist.html">QList</a>, <a href="qstringlist.html">QStringList</a> is <a href="implicit-sharing.html">implicitly shared</a>. It provides fast index-based access as well as fast insertions and removals. Passing string lists as value parameters is both fast and safe.</p> <p>All of <a href="qlist.html">QList</a>'s functionality also applies to <a href="qstringlist.html">QStringList</a>. For example, you can use <a href="qlist.html#isEmpty">isEmpty</a>() to test whether the list is empty, and you can call functions like <a href="qlist.html#append">append</a>(), <a href="qlist.html#prepend">prepend</a>(), <a href="qlist.html#insert">insert</a>(), <a href="qlist.html#replace">replace</a>(), <a href="qlist.html#removeAll">removeAll</a>(), <a href="qlist.html#removeAt">removeAt</a>(), <a href="qlist.html#removeFirst">removeFirst</a>(), <a href="qlist.html#removeLast">removeLast</a>(), and <a href="qlist.html#removeOne">removeOne</a>() to modify a <a href="qstringlist.html">QStringList</a>. In addition, <a href="qstringlist.html">QStringList</a> provides a few convenience functions that make handling lists of strings easier:</p> <a name="initializing"></a> <h3 >Initializing</h3> <p>The default constructor creates an empty list. You can use the initializer-list constructor to create a list with elements:</p> <pre class="cpp"> <span class="type"><a href="qstringlist.html#QStringList">QStringList</a></span> fonts <span class="operator">=</span> { <span class="string">"Arial"</span><span class="operator">,</span> <span class="string">"Helvetica"</span><span class="operator">,</span> <span class="string">"Times"</span> }; </pre> <a name="adding-strings"></a> <h3 >Adding Strings</h3> <p>Strings can be added to a list using the <a href="qlist.html#insert">insert()</a> <a href="qlist.html#append">append()</a>, <a href="qlist.html#operator-2b-eq">operator+=</a>() and <a href="qstringlist.html#operator-lt-lt">operator<<</a>() functions.</p> <p><a href="qstringlist.html#operator-lt-lt">operator<<</a>() can be used to conveniently add multiple elements to a list:</p> <pre class="cpp"> fonts <span class="operator"><</span><span class="operator"><</span> <span class="string">"Courier"</span> <span class="operator"><</span><span class="operator"><</span> <span class="string">"Verdana"</span>; </pre> <a name="iterating-over-the-strings"></a> <h3 >Iterating Over the Strings</h3> <p>To iterate over a list, you can either use index positions or <a href="qlist.html">QList</a>'s Java-style and STL-style iterator types:</p> <p>Indexing:</p> <pre class="cpp"> <span class="keyword">for</span> (<span class="type">int</span> i <span class="operator">=</span> <span class="number">0</span>; i <span class="operator"><</span> fonts<span class="operator">.</span>size(); <span class="operator">+</span><span class="operator">+</span>i) cout <span class="operator"><</span><span class="operator"><</span> fonts<span class="operator">.</span>at(i)<span class="operator">.</span>toLocal8Bit()<span class="operator">.</span>constData() <span class="operator"><</span><span class="operator"><</span> endl; </pre> <p>Java-style iterator:</p> <pre class="cpp"> <span class="type"><a href="qstringlist.html#QStringListIterator-typedef">QStringListIterator</a></span> javaStyleIterator(fonts); <span class="keyword">while</span> (javaStyleIterator<span class="operator">.</span>hasNext()) cout <span class="operator"><</span><span class="operator"><</span> javaStyleIterator<span class="operator">.</span>next()<span class="operator">.</span>toLocal8Bit()<span class="operator">.</span>constData() <span class="operator"><</span><span class="operator"><</span> endl; </pre> <p>STL-style iterator:</p> <pre class="cpp"> <span class="type"><a href="qstringlist.html#QStringList">QStringList</a></span><span class="operator">::</span>const_iterator constIterator; <span class="keyword">for</span> (constIterator <span class="operator">=</span> fonts<span class="operator">.</span>constBegin(); constIterator <span class="operator">!</span><span class="operator">=</span> fonts<span class="operator">.</span>constEnd(); <span class="operator">+</span><span class="operator">+</span>constIterator) cout <span class="operator"><</span><span class="operator"><</span> (<span class="operator">*</span>constIterator)<span class="operator">.</span>toLocal8Bit()<span class="operator">.</span>constData() <span class="operator"><</span><span class="operator"><</span> endl; </pre> <p>The <a href="qstringlist.html#QStringListIterator-typedef">QStringListIterator</a> class is simply a type definition for <a href="qlistiterator.html">QListIterator</a><<a href="qstring.html">QString</a>>. <a href="qstringlist.html">QStringList</a> also provide the <a href="qstringlist.html#QMutableStringListIterator-typedef">QMutableStringListIterator</a> class which is a type definition for <a href="qmutablelistiterator.html">QMutableListIterator</a><<a href="qstring.html">QString</a>>.</p> <a name="manipulating-the-strings"></a> <h3 >Manipulating the Strings</h3> <p><a href="qstringlist.html">QStringList</a> provides several functions allowing you to manipulate the contents of a list. You can concatenate all the strings in a string list into a single string (with an optional separator) using the <a href="qstringlist.html#join">join</a>() function. For example:</p> <pre class="cpp"> <span class="type"><a href="qstring.html">QString</a></span> str <span class="operator">=</span> fonts<span class="operator">.</span>join(<span class="string">", "</span>); <span class="comment">// str == "Arial, Helvetica, Times, Courier"</span> </pre> <p>The argument to join can be a single character or a string.</p> <p>To break up a string into a string list, use the <a href="qstring.html#split">QString::split</a>() function:</p> <pre class="cpp"> <span class="type"><a href="qstringlist.html#QStringList">QStringList</a></span> list; list <span class="operator">=</span> str<span class="operator">.</span>split(<span class="char">','</span>); <span class="comment">// list: ["Arial", "Helvetica", "Times", "Courier"]</span> </pre> <p>The argument to split can be a single character, a string, a <a href="qregularexpression.html">QRegularExpression</a> or a (deprecated) <a href="qregexp.html">QRegExp</a>.</p> <p>In addition, the <a href="qstringlist.html#operator-2b">operator+</a>() function allows you to concatenate two string lists into one. To sort a string list, use the <a href="qstringlist.html#sort">sort</a>() function.</p> <p><a href="qstring.html">QString</a> list also provides the <a href="qstringlist.html#filter">filter</a>() function which lets you to extract a new list which contains only those strings which contain a particular substring (or match a particular regular expression):</p> <pre class="cpp"> <span class="type"><a href="qstringlist.html#QStringList">QStringList</a></span> monospacedFonts <span class="operator">=</span> fonts<span class="operator">.</span>filter(<span class="type"><a href="qregularexpression.html">QRegularExpression</a></span>(<span class="string">"Courier|Fixed"</span>)); </pre> <p>The <a href="qstringlist.html#contains">contains</a>() function tells you whether the list contains a given string, while the <a href="qstringlist.html#indexOf">indexOf</a>() function returns the index of the first occurrence of the given string. The <a href="qstringlist.html#lastIndexOf">lastIndexOf</a>() function on the other hand, returns the index of the last occurrence of the string.</p> <p>Finally, the <a href="qstringlist.html#replaceInStrings">replaceInStrings</a>() function calls <a href="qstring.html#replace">QString::replace</a>() on each string in the string list in turn. For example:</p> <pre class="cpp"> <span class="type"><a href="qstringlist.html#QStringList">QStringList</a></span> files; files <span class="operator"><</span><span class="operator"><</span> <span class="string">"$QTDIR/src/moc/moc.y"</span> <span class="operator"><</span><span class="operator"><</span> <span class="string">"$QTDIR/src/moc/moc.l"</span> <span class="operator"><</span><span class="operator"><</span> <span class="string">"$QTDIR/include/qconfig.h"</span>; files<span class="operator">.</span>replaceInStrings(<span class="string">"$QTDIR"</span><span class="operator">,</span> <span class="string">"/usr/lib/qt"</span>); <span class="comment">// files: [ "/usr/lib/qt/src/moc/moc.y", ...]</span> </pre> </div> <p><b>See also </b><a href="qstring.html">QString</a>.</p> <!-- @@@QStringList --> <div class="func"> <h2>Member Function Documentation</h2> <!-- $$$QStringList[overload1]$$$QStringList --> <h3 class="fn" id="QStringList"><a name="QStringList"></a>QStringList::<span class="name">QStringList</span>()</h3> <p>Constructs an empty string list.</p> <!-- @@@QStringList --> <!-- $$$QStringList$$$QStringListconstQString& --> <h3 class="fn" id="QStringList-1"><a name="QStringList-1"></a>QStringList::<span class="name">QStringList</span>(const <span class="type"><a href="qstring.html">QString</a></span> &<i>str</i>)</h3> <p>Constructs a string list that contains the given string, <i>str</i>.
