Hello,
I'm experiencing odd errors on both windows and linux with the following
code:
import sys
from PyQt4.QtCore import *
from PyQt4.QtGui import *
class Options(QDialog):
def __init__(self, values):
QDialog.__init__(self)
self.values = values
fooEdit = QLineEdit(values['foo'])
self.connect(fooEdit, SIGNAL('textChanged(QString)'),
lambda value: self.optionChanged('foo', value))
barEdit = QLineEdit(values['bar'])
self.connect(barEdit, SIGNAL('textChanged(QString)'),
lambda value: self.optionChanged('bar', value))
layout = QVBoxLayout()
layout.addWidget(fooEdit)
layout.addWidget(barEdit)
self.setLayout(layout)
def optionChanged(self, option, value):
self.values[option] = value
print self.values
def main(args):
app = QApplication(args)
values = dict(foo='', bar='')
dialog = Options(values)
dialog.show()
app.exec_()
if __name__ == '__main__':
main(sys.argv)
If I type a character in fooEdit, another character in barEdit, and then
delete the character from barEdit I get an unhandled win32 exception occured
in python.exe on windows and segfault on linux.
If I type a character in fooEdit, delete it, and then type a character in
barEdit I get:
{'foo': PyQt4.QtCore.QString(u'a'), 'bar': ''}
{'foo': PyQt4.QtCore.QString(u''), 'bar': ''}
{'foo': Traceback (most recent call last):
File "L:\home\dev\python\test.py", line 17, in <lambda>
lambda value: self.optionChanged('bar', value))
File "L:\home\dev\python\test.py", line 27, in optionChanged
print self.values
MemoryError
I'm using Python 2.5.4 and PyQt 4.4.3-1
Thanks in advance for any help.
Denis
