pyqt4 - QObject and QThread relations -


i have pyqt4 gui allows me import multiple .csv files. i've created loop goes through list of tuples have following parameters (filename + location of file, filename, bool,bool, set of dates in file)=tup. i've created several classes gui refers in order pull parameters off projects profile. let's call class profile(). have class has lot of functions based on formatting, such datetime, text edits,etc...let's call classmyformatting(). created qthread class created each file in list, , 1 called import_file(qthread). , lets class takes in few parameters __init__(self,tup).

my ideal goal able make independent instance of myformatting() , profile() import_file(qthread). trying head around on how utilize qobject capabilities solve this..but keep getting error thread being destroyed while still running.

for tup in importedlist:     importfile = import_file(tup)     self.connect(importfile,qtcore.signal('savedfile(pyqt_pyobject()'),self.printstuffpassed)     importfile.start()

i thinking of having 2 classes declared 

myformatting(qobject):     def __init__(self):         qobject.__init__(self)      def func1(self,stuff):          dostuff     def func2(self):          morestuff  profile(qobject):     def __init__(self):         qobject.__init__(self)      def func11(self,stuff):          dostuff     def func22(self):          morestuff

and qthread:

import_file(qthread):     def __init__(self,tup):         qthread.__init(self)         common_calc_stuff = self.calc(tup[4])         f = open(tup[0] + '.csv', 'w')         self.tup = tup         # thought of pulling instance thread         self.mf = myformatting()         self.mf_thread = qtcore.qthread()         self.mf.movetothread(self.mf_thread)         self.mf_thread.start()          self.prof = profile()         self.prof_thread = qtcore.qthread()         self.prof.movetothread(self.prof_thread)         self.prof_thread.start()       def func33(self,stuff):          dostuff          self.prof.func11(tup[4])      def func44(self):          morestuff      def run(self):         if self.tup[3] == true:             self.func33             self.mf.func2         elif self.tup[3] ==false:             self.func44         if self.tup[2] == true:             self.prof.func22         self.emit(qtcore.signal('savedfile()',)

am totally thinking of wrong way? how can keep of same structure have coding , still able implement multithreading , not have same resource tapped @ same time, think reason why qui keeps crashing? or how can make sure each instance of objects turned off don't interfere other instances?
