Is there anyway to get 2 python threads to talk to one another?
I have a GUI which is spawning a thread to make a large calculation (that
way the GUI does not appear to be non responsive). I am trying to attach a
progress bar to the threaded action. As the thread is calculating data, I
would like it to communicate with the other (progress) thread to update it.
On windows, when I spawn the progress bar without using threads, the
progress bar stalls.... <<this does not happen on linux.>> So I thought by
spawning the progress bar by using a thread, it would not stall....... If
anyone can think of another technique.... I am all ears.
~~~~~~~~~~START SAMPLE~~~~~~~~~~~~~~~~~~~~~~~~
def progressBar(status):
mroot = Tkinter.Tk(className='Worker Bee')
metric = Meter(mroot, relief='ridge', bd=3)
metric.pack(fill='x')
metric.set(status, 'Starting ...')
def fetchFiles(file1,file2,file3):
method = ''
print file1
print file2
print file3
f1 = fopen(file1)
a = f1.readlines(); f1.close()
d1 = {}
for c in a:
for m in mailsrch.findall(c):
d1[m.lower()] = None
####I Would like to Update the progress bar running in the other thread
here.
## set status = .33 and update progress bar.
if file2 == '':
domain(d1,file3)
#...
def startProc():
status = 0
thread.start_new_thread(fetchFiles, (f1name,f2name,f3name,))
thread.start_new_thread(progressBar, (status,))
