strange QLineEdit problem in PyQt

[taco]

hi,
I have a form containing a few QLineedits and I wish to retrieve the 
contents only after pressing a QPushButton.
a looks like:
class Contract(QtGui.QWidget):
  def __init__(self,fileInfo, parent=None):
QtGui.QWidget.__init__(self,parent)
self.name = QtGui.QLineEdit("")
.
self.createDoc = QtGui.QPushButton("do it")
self.connect(createDoc,QtCore.SIGNAL("clicked()"),self.Foo)
mainLayout.addWidget(self.name)
mainLayout.addWidget(sef.createDoc)

 def Foo(self):
   print self.name.text()

when executing this I get only a few characters back from the line. It's 
incomplete. How to retrieve the complete string? I don't need a signal for 
every typed character.

ah, I solved it myself. for completeness reasons. I had upgraded python for 
reportlab which needed this python version, while still using a pyqt which 
was compiled for 2.6. After compilation and changing pythonpath to the right 
site-packages dir it's working

not sure if I understand you well, but how about a server application which
accepts 2 clients which can send messages which are output on the serial
device? The serial device access protected with a mutex while receiving
messages done in 2 threads or something.
