Hi, I got it.
Someone may also need this. I am trying to serialize QPixmap to send
it over network. Here's the solution. Qt classes cannot be pickled.
------------
pixmap = ````This is a pixmap already in memory''''
buffer = QBuffer()
pixmap.save(buffer, 'XPM')
data = buffer.getData()
-----------
from qt import *
from cStringIO import StringIO
class QBuffer(QIODevice):
def __init__(self):
QIODevice.__init__(self)
self.open( IO_ReadOnly)
def open(self, mode):
self.__io = StringIO()
return True
def close(self):
self.__io.close()
def flush(self):
self.__io.flush()
def readAll(self):
return self.__io.read()
def getch(self):
return self.__io.read(1)
def readBlock(self, size):
result = self.__io.read(size)
if result:
return (result,)
return None
def writeBlock(self, data, length=None):
if type(data) == QByteArray:
data = data.data()
self.__io.write(data)
return len(data)
def getData(self):
return self.__io.getvalue()

Hi,
I am trying to save a QPixmap onto a str object. I tried using
QBuffer. But QBuffer does not exist in pyqt3. I am using the kubuntu's
default pyqt3 package which is 3.5.1. Sip version is 4.3.2.
I don't want to use temporary files. Can you help me.
Mike
