SOLVED Create a download progress bar in python

Hi,
I found the following functions on a stackoverflow topic, and I want to apply it on c4d.gui.GeDialog.
I put more details in the code:

import urllib2

def chunk_report(bytes_so_far, chunk_size, total_size):
    percent = float(bytes_so_far) / total_size
    percent = round(percent*100, 2)

    sys.stdout.write("Downloaded %d of %d bytes (%0.2f%%)\r" % 
        (bytes_so_far, total_size, percent))

    if bytes_so_far >= total_size:
        sys.stdout.write('\n')

def chunk_read(response, chunk_size=8192, report_hook=None):
   total_size = response.info().getheader('Content-Length').strip()
   total_size = int(total_size)
   bytes_so_far = 0

   while 1:
      chunk = response.read(chunk_size)
      bytes_so_far += len(chunk)

      if not chunk:
         break

      if report_hook:
        report_hook(bytes_so_far, chunk_size, total_size)

   return bytes_so_far

class Update(c4d.gui.GeDialog):
    UPDATE_BTN = 1000
    PROGRESS = 1001
    PROGRESSBAR = 1002
    state = ""

    def CreateLayout(self) :
        self.AddButton(self.UPDATE_BTN, flags = c4d.BFH_LEFT, inith = 13, name = "Update")
        self.AddStaticText(self.PROGRESS, flags=c4d.BFH_SCALEFIT, initw=0, inith=0, name=self.state, borderstyle=0)

        # I want take the percentage value from the function chunk_report() and apply it to the following CUSTOMGUI_PROGRESSBARCUSTOMGUI_PROGRESSBAR
        self.GroupBegin(id=0, flags=c4d.BFH_LEFT, cols=1, rows=0)
        self.GroupBorderNoTitle(c4d.BORDER_THIN_IN)
        self.AddCustomGui(self.PROGRESSBAR, c4d.CUSTOMGUI_PROGRESSBAR, "", c4d.BFH_SCALEFIT|c4d.BFV_SCALEFIT,200, 8)        
        self.GroupEnd()

    def Command(self, id, msg):

        if id == self.UPDATE_BTN :
            filedata = urllib2.urlopen('https://www.domainname.com/file.zip')
            chunk_read(filedata, report_hook= chunk_report)

            self.SetString(self.PROGRESS, "Or showing the write result of chunk_report() function here?") # <---

Thanks

Hi,
I found the solution.

tx, but how can i use this in a simple scenario?
it doesnt do anything when pasted into the script manager

@indexofrefraction

Hi,
Here is a full example that you can test it on script manager:

# The following code allow to download a file and then save it on the desktop

@indexofrefraction and just in case you have this example from CUSTOMGUI_PROGRESSBAR if you want a more minimal script.
