<hr><h2><a name="details"></a>Detailed Description</h2>
The QString class provides an abstraction of Unicode text and the classic C null-terminated char array (<var>char*</var>).
<p>
QString uses <a href="shclass.html">implicit sharing</a>, and so it
is very efficient and easy to use.
<p>In all QString methods that take <var>const char*</var> parameters,
the <var>const char*</var> is interpreted as a classic C-style
0-terminated ASCII string. It is legal for the <var>const
char*</var> parameter to be 0. The results are undefined if the
<var>const char*</var> string is not 0-terminated. Functions that
copy classic C strings into a QString will not copy the terminating
0-character. The <a href="qchar.html">QChar</a> array of the QString (as returned by
<a href="#202a1d">unicode</a>()) is not terminated by a null.
<p>A QString that has not been assigned to anything is <em>null,</em> i.e. both
the length and data pointer is 0. A QString that references the empty
string ("", a single '\0' char) is <em>empty.</em> Both null and empty
QStrings are legal parameters to the methods. Assigning <var>const char
* 0</var> to QString gives a null QString.
<p>Note that if you find that you are mixing usage of <a href="qcstring.html">QCString</a>, QString,
and <a href="qbytearray.html">QByteArray</a>, this causes lots of unnecessary copying and might
indicate that the true nature of the data you are dealing with is
uncertain. If the data is NUL-terminated 8-bit data, use QCString;
if it is unterminated (ie. contains NULs) 8-bit data, use QByteArray;
if it is text, use QString.

<h3 class="fn"><a name="8f3a2b"></a>QString::QString()</h3>
<p>Constructs a null string.
<p>See also <a href="#7a8210">isNull</a>().
<h3 class="fn"><a name="ad6b2a"></a>QString::QString(<a href="qchar.html">QChar</a>ch)</h3>
<p>Constructs a string containing the one character <em>ch.</em>
<h3 class="fn"><a name="72a5f7"></a>QString::QString(const<a href="qbytearray.html">QByteArray</a>&ba)</h3>
<p>Constructs a string that is a deep copy of <em>ba</em> interpreted as
a classic C string.
<h3 class="fn"><a name="b6d151"></a>QString::QString(const<a href="qchar.html">QChar</a>*unicode, uintlength)</h3>
<p>Constructs a string that is a deep copy of the
first <em>length</em> <a href="qchar.html">QChar</a> in the array <em>unicode.</em>
<p>If <em>unicode</em> and <em>length</em> are 0, a null string is created.
<p>If only <em>unicode</em> is 0, the string is empty, but has
<em>length</em> characters of space preallocated - QString expands
automatically anyway, but this may speed some cases up a little.
<p>See also <a href="#7a8210">isNull</a>().
<h3 class="fn"><a name="e1333a"></a>QString::QString(constQString&s)</h3>
<p>Constructs an implicitly-shared copy of <em>s.</em>
<h3 class="fn"><a name="4410e2"></a>QString::QString(constchar*str)</h3>
<p>Constructs a string that is a deep copy of <em>str,</em> interpreted as a
classic C string.
<p>If <em>str</em> is 0 a null string is created.
<p>This is a cast constructor, but it is perfectly safe: converting a Latin1
const char* to QString preserves all the information.
You can disable this constructor by
defining QT_NO_CAST_ASCII when you compile your applications.
You can also make QString objects by using <a href="#7a6b4e">setLatin1</a>()/<a href="#0b1906">fromLatin1</a>(), or
<a href="#47169a">fromLocal8Bit</a>(), <a href="#9465e8">fromUtf8</a>(), or whatever encoding is appropriate for
the 8-bit data you have.
<p>See also <a href="#7a8210">isNull</a>().
<h3 class="fn"><a name="f3b58c"></a>QString::~QString()</h3>
<p>Destroys the string and frees the "real" string, if this was the last
copy of that string.
<h3 class="fn"><a name="e366aa"></a>QString::operatorconstchar*()const</h3>
<p>Returns <a href="#ea8169">latin1</a>(). Be sure to see the warnings documented there.
Note that for new code which you wish to be strictly Unicode-clean,
you can define the macro QT_NO_ASCII_CAST when compiling your code
to hide this function so that automatic casts are not done. This
has the added advantage that you catch the programming error
described under <a href="#e21796">operator!</a>().
<h3 class="fn">QString&<a name="7478cb"></a>QString::append(<a href="qchar.html">QChar</a>ch)</h3>
<p>Appends <em>ch</em> to the string and returns a reference to the result.

Equivalent to <a href="#1f1ea5">operator+=</a>().
<h3 class="fn">QString<a name="8bd12a"></a>QString::arg(constQString&a, intfieldwidth=0)const</h3>
<p>Returns a string equal to this one, but with the lowest-numbered
occurrence of <code>%i</code> (for a positive integer i) replaced by <em>a.</em>
<p><pre> label.setText( tr("Rename %1 to %2?").arg(oldName).arg(newName) );
</pre>
<p><em>fieldwidth</em> is the minimum amount of space <em>a</em> is padded to. A
positive value produces right-aligned text, while a negative value
produces left aligned text.<p><b>Warning:</b> Using arg() for constructing "real" sentences
programmatically is likely to lead to translation problems.
Inserting objects like numbers or file names is fairly safe.<p><b>Warning:</b> Relying on spaces to create alignment is prone to lead to
translation problems.
<p>If there is no <code>%i</code> pattern, a warning message (<a href="qapplication.html#290ef4">qWarning</a>()) is
printed and the text as appended at the end of the string. This is
error recovery and should not occur in correct code.

<h3 class="fn">constchar*<a name="c3848e"></a>QString::ascii()const</h3>
<p><b>This function is obsolete.</b> It is provided to keep old source working, and will probably be removed in a future version of Qt. We strongly advise against using it in new code.<p>
<p>This functions simply calls <a href="#ea8169">latin1</a>() and returns the result.
<h3 class="fn"><a href="qchar.html">QChar</a><a name="4f6a13"></a>QString::at(uint)const</h3>
<p>Returns the character at <em>i,</em> or 0 if <em>i</em> is beyond the length
of the string.
<p>Note: If this QString is not const or const&, the non-const at()
will be used instead, which will expand the string if <em>i</em> is beyond
the length of the string.
<h3 class="fn"><a href="qcharref.html">QCharRef</a><a name="f8c48b"></a>QString::at(uinti)</h3>
<p>Returns a reference to the character at <em>i,</em> expanding
the string with QChar::null if necessary. The resulting reference
can then be assigned to, or otherwise used immediately, but
becomes invalid once further modifications are made to the string.
<h3 class="fn">QChar::Direction<a name="d09db6"></a>QString::basicDirection()</h3>
<p>This function returns the basic directionality of the string (QChar::DirR for

<p>Note that this function is not supported in Qt 2.0, and is merely
for experimental and illustrative purposes. It is mainly of interest
to those experimenting with Arabic and other composition-rich texts.
<p>Applies possible ligatures to a QString, useful when composition-rich
text requires rendering with glyph-poor fonts, but also
makes compositions such as <a href="qchar.html">QChar</a>(0x0041) ('A') and QChar(0x0308)
(Unicode accent diaresis) giving QChar(0x00c4) (German A Umlaut).
<h3 class="fn"><a href="qchar.html">QChar</a><a name="a93639"></a>QString::constref(uinti)const</h3>
<p>Equivalent to <a href="#4f6a13">at</a>(i), this returns the <a href="qchar.html">QChar</a> at <em>i</em> by value.

The <a href="qcharref.html">QCharRef</a> internal class can be used much like a constant <a href="qchar.html">QChar</a>, but
if you assign to it, you change the original string (which enlarges

<h3 class="fn">QString<a name="c82882"></a>QString::rightJustify(uintwidth, <a href="qchar.html">QChar</a>fill='', booltruncate=FALSE)const</h3>
<p>Returns a string of length <em>width</em> that contains pad
characters followed by the string.
<p>If the length of the string exceeds <em>width</em> and <em>truncate</em> is FALSE,
then the returned string is a copy of the string.
If the length of the string exceeds <em>width</em> and <em>truncate</em> is TRUE,
then the returned string is a <a href="#324816">left</a>(<em>width).</em>
<p>Example:
<pre> <a href="qstring.html">QString</a> s("pie");
<a href="qstring.html">QString</a> t = s.<a href="#c82882">rightJustify</a>(8, '.'); // t == ".....pie"

<h3 class="fn">void<a name="f0c33f"></a>QString::setExpand(uintindex, <a href="qchar.html">QChar</a>c)</h3>
<p><b>This function is obsolete.</b> It is provided to keep old source working, and will probably be removed in a future version of Qt. We strongly advise against using it in new code.<p>
<p>Sets the character at position <em>index</em> to <em>c</em> and expands the
string if necessary, filling with spaces.
<p>This method is redundant in Qt 2.x, because operator[] will expand
the string as necessary.
<h3 class="fn">QString&<a name="7a6b4e"></a>QString::setLatin1(constchar*str, intlen=-1)</h3>
<p>Sets this string to <em>str,</em> interpreted as a classic Latin 1 C string.
If the <em>len</em> argument is negative (default), it is set to strlen(str).
<p>If <em>str</em> is 0 a null string is created. If <em>str</em> is "" an empty
string is created.
<p>See also <a href="#7a8210">isNull</a>() and <a href="#c62623">isEmpty</a>().
<h3 class="fn">QString&<a name="2a0391"></a>QString::setNum(double<a href="n.html">n</a>, charf='g', intprec=6)</h3>
<p>Sets the string to the printed value of <em><a href="n.html">n</a>,</em> formatted in the <em>f</em>
format with <em>prec</em> precision, and returns a reference to the
string.
<p><em>f</em> can be 'f', 'F', 'e', 'E', 'g' or 'G', all of which have the
same meaning as for <a href="#926f67">sprintf</a>().
<h3 class="fn">QString&<a name="352089"></a>QString::setNum(int<a href="n.html">n</a>, intbase=10)</h3>
<p>Sets the string to the printed value of <em><a href="n.html">n</a></em> and returns a reference
to the string.
<h3 class="fn">QString&<a name="badcf2"></a>QString::setNum(long<a href="n.html">n</a>, intbase=10)</h3>
<p>Sets the string to the printed value of <em><a href="n.html">n</a></em> and returns a
reference to the string.
<p>The value is converted to <em>base</em> notation (default is decimal).
The base must be a value from 2 to 36.
<h3 class="fn">QString&<a name="68f34e"></a>QString::setNum(short<a href="n.html">n</a>, intbase=10)</h3>
<p>Sets the string to the printed value of <em><a href="n.html">n</a></em> and returns a reference
to the string.
<h3 class="fn">QString&<a name="ed3713"></a>QString::setNum(uint<a href="n.html">n</a>, intbase=10)</h3>
<p>Sets the string to the printed unsigned value of <em><a href="n.html">n</a></em> and returns a
reference to the string.

<p>Sets the string to the printed unsigned value of <em><a href="n.html">n</a></em> and
returns a reference to the string.
<p>The value is converted to <em>base</em> notation (default is decimal).
The base must be a value from 2 to 36.
<h3 class="fn">QString&<a name="4ff814"></a>QString::setNum(ushort<a href="n.html">n</a>, intbase=10)</h3>
<p>Sets the string to the printed unsigned value of <em><a href="n.html">n</a></em> and returns a
reference to the string.
<h3 class="fn">QString&<a name="7887b0"></a>QString::setNum(float<a href="n.html">n</a>, charf='g', intprec=6)</h3>
<p>This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
<h3 class="fn">QString&<a name="a01b6c"></a>QString::setUnicode(const<a href="qchar.html">QChar</a>*unicode, uintlen)</h3>
<p>Resizes the string to <em>len</em> unicode characters and copies <em>unicode</em>
into the string. If <em>unicode</em> is null, nothing is copied, but the
string is resized to <em>len</em> anyway. If <em>len</em> is zero, the string
becomes a <a href="#7a8210">null</a> string.
<p>See also <a href="#7a6b4e">setLatin1</a>() and <a href="#7a8210">isNull</a>().
<h3 class="fn">QString&<a name="bf4cce"></a>QString::setUnicodeCodes(constushort*unicode_as_ushorts, uintlen)</h3>
<p>Resizes the string to <em>len</em> unicode characters and copies
<em>unicode_as_ushorts</em> into the string (on some X11 client
platforms this will involve a byte-swapping pass).
<p>If <em>unicode</em> is null, nothing is copied, but the
string is resized to <em>len</em> anyway. If <em>len</em> is zero, the string
becomes a <a href="#7a8210">null</a> string.
<p>See also <a href="#7a6b4e">setLatin1</a>() and <a href="#7a8210">isNull</a>().
<h3 class="fn">QString<a name="cf6c55"></a>QString::simplifyWhiteSpace()const</h3>
<p>Returns a new string that has white space removed from the start and the end,
plus any sequence of internal white space replaced with a single space
(ASCII 32).
<p>White space means any character for which <a href="qchar.html#53ba36">QChar::isSpace</a>() returns
TRUE. This includes ASCII characters 9 (TAB), 10 (LF), 11 (VT), 12
(FF), 13 (CR), and 32 (Space).
<p><pre> <a href="qstring.html">QString</a> s = " lots\t of\nwhite space ";
<a href="qstring.html">QString</a> t = s.<a href="#cf6c55">simplifyWhiteSpace</a>(); // t == "lots of white space"
</pre>
<p>See also <a href="#574c92">stripWhiteSpace</a>().
<h3 class="fn">QString&<a name="926f67"></a>QString::sprintf(constchar*cformat, ...)</h3>
<p>Safely builds a formatted string from a format string and an
arbitrary list of arguments. The format string supports all
the escape sequences of printf() in the standard C library.
<p>The %s escape sequence expects a <a href="#011d3d">utf8</a>() encoded string.
The format string <em>cformat</em> is expected to be in latin1. If you need a unicode
format string, use <a href="#8bd12a">QString::arg</a>() instead. For typesafe
string building, with full Unicode support, you can use <a href="qtextostream.html">QTextOStream</a>
like this:
<p><pre> <a href="qstring.html">QString</a> str;
<a href="qstring.html">QString</a> s = ...;
int x = ...;
<a href="qtextostream.html">QTextOStream</a>(&str) << s << " : " << x;
</pre>
<p>For <a href="qobject.html#2418a9">translations,</a> especially if the
strings contains more than one escape sequence, you should consider
using the <a href="#8bd12a">arg</a>() function instead. This allows the order of the
replacements to be controlled by the translator, and has Unicode
support.
<p>See also <a href="#8bd12a">arg</a>().
