|
|---|
| 108 | The QTextStream class provides basic functions for reading
|
|---|
| 109 | and writing text using a <a href="qiodevice.html">QIODevice</a>.
|
|---|
| 110 | <p>
|
|---|
| 111 |
|
|---|
| 112 |
|
|---|
| 113 | <p> The text stream class has a functional interface that is very
|
|---|
| 114 | similar to that of the standard C++ iostream class.
|
|---|
| 115 | <p> Qt provides several global functions similar to the ones in iostream:

|

|

| 129 | <tr bgcolor="#f0f0f0"> <td valign="top">qSetPrecision(int) <td valign="top">sets the <a href="#precision">precision</a> to the given argument
|
|---|
| 130 | </table></center>
|
|---|
| 131 | <p> <b>Warning:</b> By default QTextStream will automatically detect whether
|
|---|
| 132 | integers in the stream are in decimal, octal, hexadecimal or
|
|---|
| 133 | binary format when reading from the stream. In particular, a
|
|---|
| 134 | leading '0' signifies octal, i.e. the sequence "0100" will be
|
|---|
| 135 | interpreted as 64.
|
|---|
| 136 | <p> The QTextStream class reads and writes text; it is not appropriate
|
|---|
| 137 | for dealing with binary data (but <a href="qdatastream.html">QDataStream</a> is).
|
|---|
| 138 | <p> By default, output of Unicode text (i.e. <a href="qstring.html">QString</a>) is done using
|
|---|
| 139 | the local 8-bit encoding. This can be changed using the
|
|---|
| 140 | <a href="#setEncoding">setEncoding</a>() method. For input, the QTextStream will auto-detect
|
|---|
| 141 | standard Unicode "byte order marked" text files; otherwise the
|
|---|
| 142 | local 8-bit encoding is used.
|
|---|
| 143 | <p> The <a href="qiodevice.html">QIODevice</a> is set in the constructor, or later using
|
|---|
| 144 | <a href="#setDevice">setDevice</a>(). If the end of the input is reached <a href="#atEnd">atEnd</a>() returns
|
|---|
| 145 | TRUE. Data can be read into variables of the appropriate type
|
|---|
| 146 | using the <a href="#operator-gt-gt">operator>></a>() overloads, or read in its entirety into a
|
|---|
| 147 | single string using <a href="#read">read</a>(), or read a line at a time using
|
|---|
| 148 | <a href="#readLine">readLine</a>(). Whitespace can be skipped over using <a href="#skipWhiteSpace">skipWhiteSpace</a>().
|
|---|
| 149 | You can set flags for the stream using <a href="#flags">flags</a>() or <a href="#setf">setf</a>(). The
|
|---|
| 150 | stream also supports <a href="#width">width</a>(), <a href="#precision">precision</a>() and <a href="#fill">fill</a>(); use <a href="#reset">reset</a>()
|
|---|
| 151 | to reset the defaults.

|
|---|
| 177 | </h3>
|
|---|
| 178 | Constructs a text stream that operates on the Unicode <a href="qstring.html">QString</a>, <em>str</em>, through an internal device. The <em>filemode</em> argument is
|
|---|
| 179 | passed to the device's open() function; see <a href="qiodevice.html#mode">QIODevice::mode</a>().
|
|---|
| 180 | <p> If you set an encoding or codec with <a href="#setEncoding">setEncoding</a>() or <a href="#setCodec">setCodec</a>(),
|
|---|
| 181 | this setting is ignored for text streams that operate on QString.
|
|---|
| 182 | <p> Example:
|
|---|
| 183 | <pre>
|
|---|
| 184 | <a href="qstring.html">QString</a> str;
|
|---|
| 185 | QTextStream ts( &str, <a href="qfile.html#open">IO_WriteOnly</a> );
|
|---|
| 186 | ts << "pi = " << 3.14; // str == "pi = 3.14"
|
|---|
| 187 | </pre>
|
|---|
| 188 |
|
|---|
| 189 | <p> Writing data to the text stream will modify the contents of the
|
|---|
| 190 | string. The string will be expanded when data is written beyond
|
|---|
| 191 | the end of the string. Note that the string will not be truncated:
|
|---|
| 192 | <pre>
|
|---|
| 193 | <a href="qstring.html">QString</a> str = "pi = 3.14";
|
|---|

| 195 | ts << "2+2 = " << 2+2; // str == "2+2 = 414"
|
|---|
| 196 | </pre>
|
|---|
| 197 |
|
|---|
| 198 | <p> Note that because QString is Unicode, you should not use
|
|---|
| 199 | <a href="#readRawBytes">readRawBytes</a>() or <a href="#writeRawBytes">writeRawBytes</a>() on such a stream.

| 207 | </h3>
|
|---|
| 208 | Constructs a text stream that operates on the byte array, <em>a</em>,
|
|---|
| 209 | through an internal <a href="qbuffer.html">QBuffer</a> device. The <em>mode</em> argument is passed
|
|---|
| 210 | to the device's open() function; see <a href="qiodevice.html#mode">QIODevice::mode</a>().
|
|---|
| 211 | <p> Example:
|

| 212 | <pre>
|
|---|
| 213 | <a href="qbytearray.html">QByteArray</a> array;
|

| 217 |
|
