Detailed Description#
Warning
This section contains snippets that were automatically translated from C++ to Python and may contain errors.
A text encoder converts text from Qt’s internal representation into an encoded text format using a specific encoding.
Converting a string from Unicode to the local encoding can be achieved using the following code:
string = "..." fromUtf16 = QStringEncoder(QStringEncoder.Utf8) encodedString = fromUtf16(string)
The encoder remembers any state that is required between calls, so converting data received in chunks, for example, when receiving it over a network, is just as easy, by calling the encoder whenever new data is available:
fromUtf16 = QStringEncoder(QStringEncoder.Utf8) encoded = QByteArray() while new_data_available(): chunk = get_new_data() encoded += fromUtf16(chunk)
The
QStringEncoder
object maintains state between chunks and therefore works correctly even if a UTF-16 surrogate character is split between chunks.QStringEncoder
objects can’t be copied because of their internal state, but can be moved.See also
- __init__()#
Default constructs an encoder. The default encoder is not valid, and can’t be used for converting text.
- __init__(encoding[, flags=QStringConverterBase.Flag.Default])
- __init__(name[, flags=QStringConverterBase.Flag.Default])
- Parameters:
name – str
flags – Combination of
Flag
- requiredSpace(inputLength)#
- Parameters:
inputLength – int
- Return type:
int
Returns the maximum amount of characters required to be able to process
inputLength
decoded data.See also
