OK, I have created smaller script, that segfaults. Here it is:
#!/usr/bin/python
from PyQt4 import *
from PyQt4.QtCore import *
from PyQt4.QtGui import *
import sys
USE_SILENT = 1
USE_REQUIRED = 2
class NumericContent:
def __init__(self, min = 0, max = 0):
self.min = min
self.max = max
def getValues(self):
return range(self.min, self.max + 1)
class Element(QObject):
def __init__(self, name, content = None, value = None):
QObject.__init__(self)
self.__name = name
self.__content = content
self.__value = value
def getValue(self):
return self.__value
def setValue(self, value):
self.__value = value
def getName(self):
return self.__name
def hasContent(self):
return self.__content != None
def getContent(self):
return self.__content
def setContent(self, content):
self.__content = content
class Attribute(Element):
def __init__(self, name, content):
Element.__init__(self, name, content)
def isFinal(self):
return True
def getValues(self):
return self.getContent().getValues()
def __repr__(self):
return str(self.getName()) + " " + str(self.getValue()) + "\n"
def display():
print str(a.getValue())
if __name__ == "__main__":
app = QApplication(sys.argv)
widget = QWidget()
box = QComboBox()
button = QPushButton("Button")
layout = QHBoxLayout()
layout.addWidget(box)
layout.addWidget(button)
widget.setLayout(layout)
widget.show()
a = Attribute('attr', NumericContent(1, 4))
for i in a.getValues():
box.addItem(QString(str(i)))
box.connect(box, SIGNAL('currentIndexChanged(QString)'), a.setValue);
box.emit(SIGNAL('currentIndexChanged(QString)'), box.currentText())
box.connect(button, SIGNAL('clicked()'), display)
sys.exit(app.exec_())
To make it segfault, you just have to run it, change value in combo
box, and push the button. If you don't change the the value in the
combo box and push the button, it will correctly print the value onto
the std out.
Furthermore, if you change method
def setValue(self, value):
self.__value = value
to
def setValue(self, value):
self.__value = str(value)
it works perfectly fine. Can anyone explain me, what have I done wrong?
