How to invoke parent's method?
Hi, pythoners: My wxPython program includes a panel whose parent is a frame. The panel has a button. When I click the button , I want to let the frame destroy. How to implement it? Could the panel invoke the frame's method? Thanks. -- http://mail.python.org/mailman/listinfo/python-list

If not, there is no point in going to sleep in the first place and the thread should just terminate when it has completed its task. If yes, I'd use a threading.Event object to .wait() on in the sub-thread rather than putting it to sleep, and then .set() the event object in the main thread when it's time to wake up the sub-thread. Hope this helps, Carsten. While , there is something wrong in my expression. What I mean is the thread will wait some time after doing some tasks. I want to know is there any method to end the thread or make it out of execution of waiting. I use time.sleep() to let the thread wait. Thanks. -- http://mail.python.org/mailman/listinfo/python-list
How to stop program when threads is sleeping
Hi, pythoners: There is a problem I couldn't dispose. I start a thread in the my program. The thread will do something before executing time.sleep(). When the user give a signal to the main thread (such as click the 'end' button or close the window), the thread should end it's running. But how to end the threading when it's sleeping? I set an flag to the thread, but it doesn't work. I also thought to put 'time.sleep()' to the main thread. But I think the main thread will not response to user's action because it is executing sleep(). Any ideas? Thanks. -- http://mail.python.org/mailman/listinfo/python-list
Try to stop thread Using flag
Hi,pythoners:
I countered some problems when I try to stop threads using flag.
These are my some important codes:
# mythread.py
def run(self):
while self.addr != '':### text waiting for processing
if not self.CONTINUE: ### flag for thread ,means to exit
the RUN func or not
break
print self.name
post(self.params, self.addr) ### func to process the text
self.addr = furl.readline().strip()
## myapp.py
def OnEndProcess(self, event):
if self.threadList:
for thread in self.threadList:
thread.CONTINUE = False
# this func is an EVENT processor. When I press the END BUTTON ,
it will be caused.
def OnBeginProcess(self, event):
for i in range(num):
if lines[i]!= '':
thread =
mythread.mythread('Thread'+str(i),lines[i], params)
self.threadList.append(thread)
print '\n Starting Threads'
for i in self.threadList:
i.start()
## this func is an EVENT processor. When I press the BEGIN BUTTON
, it will be caused.
By test I found this truely acts as supposed:thread exited the *run()*
func. But when I press the BEGIN BUTTON again, an Error was caused:
thread already started.
It's said that if the *run()* func is finished, the thread will become
dead. So how to interprete this?
Any solution?
Thanks.

How to Restart a thread
class mythread(threading.Thread):
def __init__(self, threadname):
threading.Thread.__init__(self, name = threadname)
def run(self):
print 'i am running'
print 'i quit run()'
thread = mythread('1')
thread.start()
print threading.activeCount() ## 1 , this means the thread is active
if not thread.isAlive():
print 'i am dead,you can restart' ### OK, this is executed. this
means the thread is no alive
thread.start() thread already started
This program presentes that the thread quit the *run()* func and is
active but not alive. How to understand this? It is said if the
thread quit the *run()* func , it's dead.
how to restart it ?
Thanks

How to get the ascii code of Chinese characters?
Hi,everyone: Have you any ideas? Say whatever you know about this. thanks. -- http://mail.python.org/mailman/listinfo/python-list
Re: How to get the ascii code of Chinese characters?
hi: what I want to do is just to make numbers as people input some Chinese character(hanzi,i mean).The same character will create the same number.So I think ascii code can do this very well. John Machin wrote: many_years_after wrote: Hi,everyone: Have you any ideas? Say whatever you know about this. Perhaps you had better explain what you mean by ascii code of Chinese characters. Chinese characters (hanzi) can be represented in many ways on a computer, in Unicode as well as many different legacy encodings, such as GB, GBK, big5, two different 4-digit telegraph codes, etc etc. They can also be spelled out in roman letters with or without tone indications (digits or accents) in the pinyin system -- is that what you mean by ascii code? Perhaps you might like to tell us what you want to do in Python with hanzi and ascii codes, so that we can give you a specific answer. With examples, please -- like what are the ascii codes for the two characters in the common greeting that comes across in toneless pinyin as ni hao?

Possibly you have create upside-down. Could you possibly be talking about an input method, in which people type in ascii letters (and maybe numbers) and the *result* is a Chinese character? In other words, what *everybody* uses to input Chinese characters? Perhaps you could ask on the Chinese Python newsgroup. *GIVE* *EXAMPLES* of what you want to do. Well, people may input from keyboard. They input some Chinese characters, then, I want to create a number. The same number will be created if they input the same Chinese characters. -- http://mail.python.org/mailman/listinfo/python-list
