Detailed Description

The QTextStream class provides a convenient interface for reading and writing text.

QTextStream can operate on a QIODevice, a QByteArray or a QString. Using QTextStream's streaming operators, you can conveniently read and write words, lines and numbers. For generating text, QTextStream supports formatting options for field padding and alignment, and formatting of numbers. Example:

QFile data("output.txt");

if (data.open(QFile::WriteOnly | QFile::Truncate)) {

QTextStream out(&data);

out << "Result: " << qSetFieldWidth(10) << left << 3.14 << 2.7;

// writes "Result: 3.14 2.7 "

}

It's also common to use QTextStream to read console input and write console output. QTextStream is locale aware, and will automatically decode standard input using the correct codec. Example:

QTextStream stream(stdin);

QString line;

do {

line = stream.readLine();

} while (!line.isNull());

Besides using QTextStream's constructors, you can also set the device or string QTextStream operates on by calling setDevice() or setString(). You can seek to a position by calling seek(), and atEnd() will return true when there is no data left to be read. If you call flush(), QTextStream will empty all data from its write buffer into the device and call flush() on the device.

Internally, QTextStream uses a Unicode based buffer, and QTextCodec is used by QTextStream to automatically support different character sets. By default, QTextCodec::codecForLocale() is used for reading and writing, but you can also set the codec by calling setCodec(). Automatic Unicode detection is also supported. When this feature is enabled (the default behavior), QTextStream will detect the UTF-16 or the UTF-32 BOM (Byte Order Mark) and switch to the appropriate UTF codec when reading. QTextStream does not write a BOM by default, but you can enable this by calling setGenerateByteOrderMark(true). When QTextStream operates on a QString directly, the codec is disabled.

There are three general ways to use QTextStream when reading text files:

Chunk by chunk, by calling readLine() or readAll().

Word by word. QTextStream supports streaming into QStrings, QByteArrays and char* buffers. Words are delimited by space, and leading white space is automatically skipped.

Character by character, by streaming into QChar or char types. This method is often used for convenient input handling when parsing files, independent of character encoding and end-of-line semantics. To skip white space, call skipWhiteSpace().

Since the text stream uses a buffer, you should not read from the stream using the implementation of a superclass. For instance, if you have a QFile and read from it directly using QFile::readLine() instead of using the stream, the text stream's internal position will be out of sync with the file's position.

By default, when reading numbers from a stream of text, QTextStream will automatically detect the number's base representation. For example, if the number starts with "0x", it is assumed to be in hexadecimal form. If it starts with the digits 1-9, it is assumed to be in decimal form, and so on. You can set the integer base, thereby disabling the automatic detection, by calling setIntegerBase(). Example:

QTextStream in("0x50 0x20");

int firstNumber, secondNumber;

in >> firstNumber; // firstNumber == 80

in >> dec >> secondNumber; // secondNumber == 0

char ch;

in >> ch; // ch == 'x'

QTextStream supports many formatting options for generating text. You can set the field width and pad character by calling setFieldWidth() and setPadChar(). Use setFieldAlignment() to set the alignment within each field. For real numbers, call setRealNumberNotation() and setRealNumberPrecision() to set the notation (SmartNotation, ScientificNotation, FixedNotation) and precision in digits of the generated number. Some extra number formatting options are also available through setNumberFlags().

Like <iostream> in the standard C++ library, QTextStream also defines several global manipulator functions:

ManipulatorDescription

bin Same as setIntegerBase(2).

oct Same as setIntegerBase(8).

dec Same as setIntegerBase(10).

hex Same as setIntegerBase(16).

showbase Same as setNumberFlags(numberFlags() | ShowBase).

forcesign Same as setNumberFlags(numberFlags() | ForceSign).

forcepoint Same as setNumberFlags(numberFlags() | ForcePoint).

noshowbase Same as setNumberFlags(numberFlags() & ~ShowBase).

noforcesign Same as setNumberFlags(numberFlags() & ~ForceSign).

noforcepoint Same as setNumberFlags(numberFlags() & ~ForcePoint).

uppercasebase Same as setNumberFlags(numberFlags() | UppercaseBase).

uppercasedigits Same as setNumberFlags(numberFlags() | UppercaseDigits).

lowercasebase Same as setNumberFlags(numberFlags() & ~UppercaseBase).

lowercasedigits Same as setNumberFlags(numberFlags() & ~UppercaseDigits).

fixed Same as setRealNumberNotation(FixedNotation).

scientific Same as setRealNumberNotation(ScientificNotation).

left Same as setFieldAlignment(AlignLeft).

right Same as setFieldAlignment(AlignRight).

center Same as setFieldAlignment(AlignCenter).

endl Same as operator<<('\n') and flush().

flush Same as flush().

reset Same as reset().

ws Same as skipWhiteSpace().

bom Same as setGenerateByteOrderMark(true).

In addition, Qt provides three global manipulators that take a parameter: qSetFieldWidth(), qSetPadChar(), and qSetRealNumberPrecision().

Member Function Documentation

new bool QtCore.QTextStream.AtEnd

(

)

Returns true if there is no more data to be read from the QTextStream; otherwise returns false. This is similar to, but not the same as calling QIODevice::atEnd(), as QTextStream also takes into account its internal Unicode buffer.

virtual void QtCore.QTextStream.CreateProxy ( )

virtual

new void QtCore.QTextStream.Dispose

(

)

new void QtCore.QTextStream.Flush

(

)

Flushes any buffered data waiting to be written to the device.

If QTextStream operates on a string, this function does nothing.

new long QtCore.QTextStream.Pos

(

)

Returns the device position corresponding to the current position of the stream, or -1 if an error occurs (e.g., if there is no device or string, or if there's a device error).

Because QTextStream is buffered, this function may have to seek the device to reconstruct a valid device position. This operation can be expensive, so you may want to avoid calling this function in a tight loop.

This function was introduced in Qt 4.2.

See also seek().

new QTextStream QtCore.QTextStream.Read

(

QChar

ch

)

Reads a character from the stream and stores it in c. Returns a reference to the QTextStream, so several operators can be nested. Example:

QTextStream in(file);

QChar ch1, ch2, ch3;

in >> ch1 >> ch2 >> ch3;

Whitespace is not skipped.

new QTextStream QtCore.QTextStream.Read

(

QByteArray

array

)

This is an overloaded function.

Converts the word to ISO-8859-1, then stores it in array.

See also QString::toLatin1().

new QTextStream QtCore.QTextStream.Read

(

ref sbyte

ch

)

This is an overloaded function.

Reads a character from the stream and stores it in c. The character from the stream is converted to ISO-5589-1 before it is stored.

See also QChar::toLatin1().

new QTextStream QtCore.QTextStream.Read

(

ref short

i

)

Reads an integer from the stream and stores it in i, then returns a reference to the QTextStream. The number is cast to the correct type before it is stored. If no number was detected on the stream, i is set to 0.

By default, QTextStream will attempt to detect the base of the number using the following rules:

PrefixBase

"0b" or "0B" 2 (binary)

"0" followed by "0-7" 8 (octal)

"0" otherwise 10 (decimal)

"0x" or "0X" 16 (hexadecimal)

"1" to "9" 10 (decimal)

By calling setIntegerBase(), you can specify the integer base explicitly. This will disable the auto-detection, and speed up QTextStream slightly.

Leading whitespace is skipped.

new QTextStream QtCore.QTextStream.Read

(

ref ushort

i

)

This is an overloaded function.

Stores the integer in the unsigned short i.

new QTextStream QtCore.QTextStream.Read

(

ref int

i

)

This is an overloaded function.

Stores the integer in the signed int i.

new QTextStream QtCore.QTextStream.Read

(

ref uint

i

)

This is an overloaded function.

Stores the integer in the unsigned int i.

new QTextStream QtCore.QTextStream.Read

(

NativeLong

i

)

This is an overloaded function.

Stores the integer in the signed long i.

new QTextStream QtCore.QTextStream.Read

(

NativeULong

i

)

This is an overloaded function.

Stores the integer in the unsigned long i.

new QTextStream QtCore.QTextStream.Read

(

ref long

i

)

Reads a character from the stream and stores it in c. Returns a reference to the QTextStream, so several operators can be nested. Example:

QTextStream in(file);

QChar ch1, ch2, ch3;

in >> ch1 >> ch2 >> ch3;

Whitespace is not skipped.

new QTextStream QtCore.QTextStream.Read

(

ref ulong

i

)

Reads a character from the stream and stores it in c. Returns a reference to the QTextStream, so several operators can be nested. Example:

QTextStream in(file);

QChar ch1, ch2, ch3;

in >> ch1 >> ch2 >> ch3;

Whitespace is not skipped.

new QTextStream QtCore.QTextStream.Read

(

ref float

f

)

Reads a real number from the stream and stores it in f, then returns a reference to the QTextStream. The number is cast to the correct type. If no real number is detect on the stream, f is set to 0.0.

As a special exception, QTextStream allows the strings "nan" and "inf" to represent NAN and INF floats or doubles.

Leading whitespace is skipped.

new QTextStream QtCore.QTextStream.Read

(

ref double

f

)

This is an overloaded function.

Stores the real number in the double f.

new QTextStream QtCore.QTextStream.Read

(

string

s

)

Reads a word from the stream and stores it in str, then returns a reference to the stream. Words are separated by whitespace (i.e., all characters for which QChar::isSpace() returns true).

Leading whitespace is skipped.

new QTextStream QtCore.QTextStream.Read

(

Pointer< sbyte >

c

)

This is an overloaded function.

Stores the word in c, terminated by a '\0' character. If no word is available, only the '\0' character is stored.

Warning: Although convenient, this operator is dangerous and must be used with care. QTextStream assumes that c points to a buffer with enough space to hold the word. If the buffer is too small, your application may crash.

If possible, use the QByteArray operator instead.

new string QtCore.QTextStream.Read

(

long

maxlen

)

Reads at most maxlen characters from the stream, and returns the data read as a QString.

This function was introduced in Qt 4.1.

See also readAll(), readLine(), and QIODevice::read().

new string QtCore.QTextStream.ReadAll

(

)

Reads the entire content of the stream, and returns it as a QString. Avoid this function when working on large files, as it will consume a significant amount of memory.

Calling readLine() is better if you do not know how much data is available.

See also readLine().

new string QtCore.QTextStream.ReadLine

(

long

maxlen = 0

)

Reads one line of text from the stream, and returns it as a QString. The maximum allowed line length is set to maxlen. If the stream contains lines longer than this, then the lines will be split after maxlen characters and returned in parts.

If maxlen is 0, the lines can be of any length. A common value for maxlen is 75.

The returned line has no trailing end-of-line characters ("\n" or "\r\n"), so calling QString::trimmed() is unnecessary.

If the stream has read to the end of the file, readLine() will return a null QString. For strings, or for devices that support it, you can explicitly test for the end of the stream using atEnd().

See also readAll() and QIODevice::readLine().

new void QtCore.QTextStream.Reset

(

)

Resets QTextStream's formatting options, bringing it back to its original constructed state. The device, string and any buffered data is left untouched.

new void QtCore.QTextStream.ResetStatus

(

)

Resets the status of the text stream.

This function was introduced in Qt 4.1.

See also QTextStream::Status, status(), and setStatus().

new bool QtCore.QTextStream.Seek

(

long

pos

)

Seeks to the position pos in the device. Returns true on success; otherwise returns false.

new void QtCore.QTextStream.SetCodec

(

string

codecName

)

Sets the codec for this stream to the QTextCodec for the encoding specified by codecName. Common values for codecName include "ISO 8859-1", "UTF-8", and "UTF-16". If the encoding isn't recognized, nothing happens.

Example:

QTextStream out(&file);

out.setCodec("UTF-8");

See also QTextCodec::codecForName() and setLocale().

new void QtCore.QTextStream.SetString	(	System.Text.StringBuilder @	string,
		QIODevice.OpenModeFlag	openMode = QIODevice.OpenModeFlag.ReadWrite
	)

Sets the current string to string, using the given openMode. If a device has already been assigned, QTextStream will call flush() before replacing it.

See also string() and setDevice().

new void QtCore.QTextStream.SkipWhiteSpace

(

)

Reads and discards whitespace from the stream until either a non-space character is detected, or until atEnd() returns true. This function is useful when reading a stream character by character.

Whitespace characters are all characters for which QChar::isSpace() returns true.

See also operator>>().

new QTextStream QtCore.QTextStream.Write

(

QBool

b

)

Writes the character c to the stream, then returns a reference to the QTextStream.

See also setFieldWidth().

new QTextStream QtCore.QTextStream.Write

(

QChar

ch

)

Writes the character c to the stream, then returns a reference to the QTextStream.

See also setFieldWidth().

new QTextStream QtCore.QTextStream.Write

(

QByteArray

array

)

This is an overloaded function.

Writes array to the stream. The contents of array are converted with QString::fromAscii().

new QTextStream QtCore.QTextStream.Write

(

sbyte

ch

)

This is an overloaded function.

Converts c from ASCII to a QChar, then writes it to the stream.

new QTextStream QtCore.QTextStream.Write

(

short

i

)

Writes the integer number i to the stream, then returns a reference to the QTextStream. By default, the number is stored in decimal form, but you can also set the base by calling setIntegerBase().

See also setFieldWidth() and setNumberFlags().

new QTextStream QtCore.QTextStream.Write

new QTextStream QtCore.QTextStream.Write

(

float

f

)

Writes the real number f to the stream, then returns a reference to the QTextStream. By default, QTextStream stores it using SmartNotation, with up to 6 digits of precision. You can change the textual representation QTextStream will use for real numbers by calling setRealNumberNotation(), setRealNumberPrecision() and setNumberFlags().

Member Data Documentation

SmokeInvocation QtCore.QTextStream.interceptor

protected

Property Documentation

new bool QtCore.QTextStream.AutoDetectUnicode

getset

Returns true if automatic Unicode detection is enabled, otherwise returns false. Automatic Unicode detection is enabled by default.

If enabled is true, QTextStream will attempt to detect Unicode encoding by peeking into the stream data to see if it can find the UTF-16 or UTF-32 BOM (Byte Order Mark). If this mark is found, QTextStream will replace the current codec with the UTF codec.

This function can be used together with setCodec(). It is common to set the codec to UTF-8, and then enable UTF-16 detection.

new QTextCodec QtCore.QTextStream.Codec

getset

Returns the codec that is current assigned to the stream.

Sets the codec for this stream to codec. The codec is used for decoding any data that is read from the assigned device, and for encoding any data that is written. By default, QTextCodec::codecForLocale() is used, and automatic unicode detection is enabled.

If QTextStream operates on a string, this function does nothing.

Warning: If you call this function while the text stream is reading from an open sequential socket, the internal buffer may still contain text decoded using the old codec.

new QIODevice QtCore.QTextStream.Device

getset

Returns the current device associated with the QTextStream, or 0 if no device has been assigned.

Sets the current device to device. If a device has already been assigned, QTextStream will call flush() before the old device is replaced.

Note: This function resets locale to the default locale ('C') and codec to the default codec, QTextCodec::codecForLocale().

new QTextStream.FieldAlignment QtCore.QTextStream.fieldAlignment

getset

Returns the current field alignment.

Sets the field alignment to mode. When used together with setFieldWidth(), this function allows you to generate formatted output with text aligned to the left, to the right or center aligned.

new int QtCore.QTextStream.FieldWidth

getset

Returns the current field width.

Sets the current field width to width. If width is 0 (the default), the field width is equal to the length of the generated text.

Note: The field width applies to every element appended to this stream after this function has been called (e.g., it also pads endl). This behavior is different from similar classes in the STL, where the field width only applies to the next element.

new bool QtCore.QTextStream.GenerateByteOrderMark

getset

Returns true if QTextStream is set to generate the UTF BOM (Byte Order Mark) when using a UTF codec; otherwise returns false. UTF BOM generation is set to false by default.

If generate is true and a UTF codec is used, QTextStream will insert the BOM (Byte Order Mark) before any data has been written to the device. If generate is false, no BOM will be inserted. This function must be called before any data is written. Otherwise, it does nothing.

new int QtCore.QTextStream.IntegerBase

getset

Returns the current base of integers. 0 means that the base is detected when reading, or 10 (decimal) when generating numbers.

Sets the base of integers to base, both for reading and for generating numbers. base can be either 2 (binary), 8 (octal), 10 (decimal) or 16 (hexadecimal). If base is 0, QTextStream will attempt to detect the base by inspecting the data on the stream. When generating numbers, QTextStream assumes base is 10 unless the base has been set explicitly.

new QLocale QtCore.QTextStream.Locale

getset

Returns the locale for this stream. The default locale is C.

This function was introduced in Qt 4.5.

Sets the locale for this stream to locale. The specified locale is used for conversions between numbers and their string representations.

The default locale is C and it is a special case - the thousands group separator is not used for backward compatibility reasons.

This function was introduced in Qt 4.5.

new QTextStream.NumberFlag QtCore.QTextStream.NumberFlags

getset

Returns the current number flags.

Sets the current number flags to flags. flags is a set of flags from the NumberFlag enum, and describes options for formatting generated code (e.g., whether or not to always write the base or sign of a number).

new QChar QtCore.QTextStream.PadChar

getset

Returns the current pad character.

Sets the pad character to ch. The default value is the ASCII space character (' '), or QChar(0x20). This character is used to fill in the space in fields when generating text.

Example:

QString s;

QTextStream out(&s);

out.setFieldWidth(10);

out.setFieldAlignment(QTextStream::AlignCenter);

out.setPadChar('-');

out << "Qt" << "rocks!";

The string s contains:

new QTextStream.RealNumberNotation QtCore.QTextStream.realNumberNotation

getset

Returns the current real number notation.

Sets the real number notation to notation (SmartNotation, FixedNotation, ScientificNotation). When reading and generating numbers, QTextStream uses this value to detect the formatting of real numbers.

new int QtCore.QTextStream.RealNumberPrecision

getset

Returns the current real number precision, or the number of fraction digits QTextStream will write when generating real numbers.

Sets the precision of real numbers to precision. This value describes the number of fraction digits QTextStream should write when generating real numbers.

The precision cannot be a negative value. The default value is 6.

virtual System.IntPtr QtCore.QTextStream.SmokeObject

getset

new QTextStream.Status QtCore.QTextStream.status

getset

Returns the status of the text stream.

Sets the status of the text stream to the status given.

Subsequent calls to setStatus() are ignored until resetStatus() is called.

This function was introduced in Qt 4.1.

new System.Text.StringBuilder QtCore.QTextStream.String

get

Returns the current string assigned to the QTextStream, or 0 if no string has been assigned.

See also setString() and device().
