Hi folks,
my threads is running well.
But I would like to implement terminating of thread. I have two approaches
but any of these is not working properly till now.
First approach:
1) class contain function: run_function()
2) over button I call:
self.thread = threading.Thread(target=self.run_function()
self.stop = threading.Event()
3) over stop button I would like to cancel thread. In that function is
written:
if self.thread.isAlive():
self.stop.set()
self.thread.join()
This approach unfortunatelly does not work.
Second approach:
class DevAssistantThread(threading.Thread):
def __init__(self, target = None):
threading.Thread.__init__(self)
self._terminate = False
self.target = target
self.stop = threading.Event()
def terminate(self):
print "terminate is called"
self._terminate = True
self.stop.set()
print "terminate is finished"
def run(self):
print "Function was run"
self.target()
print "Function was finished"
while True:
if self._terminate:
print "Thread is canceled"
break
class runWindow(object):
def __init__(self, parent, finalWindow, builder, assistant):
self.thread = DevAssistantThread(target=self.devassistant_start)
# Thread is started during the opening window
def open_window(self, widget, data=None):
dirname, projectname = self.parent.pathWindow.get_data()
self.runWindow.show_all()
self.cancelBtn.set_sensitive(False)
self.thread.start()
self.cancelBtn.set_sensitive(True)
# Function for cancelling thread
def close_btn(self, widget, data=None):
name = self.cancelBtn.get_label()
if name == "Cancel":
print self.thread.isAlive()
if self.thread.isAlive():
Gdk.threads_enter()
self.stop.set()
self.thread.join()
Gdk.threads_leave()
Gtk.main_quit()
else:
print "Quit dialog"
Gtk.main_quit()
def devassistant_start(self):
logger_gui.info("Thread run")
path =
self.assistant.get_selected_subassistant_path(**self.parent.kwargs)
pr = path_runner.PathRunner(path, self.parent.kwargs)
try:
pr.run()
Gdk.threads_enter()
self.cancelBtn.set_label("Close")
Gdk.threads_leave()
except exceptions.ExecutionException as ex:
pass
Unfortunatelly also second approach is not working well. Respectivelli
it does not work at all.
Do you have any idea where I have made mistake?
Thank you in advance
