How to return a matrix of checkbox from client to server side?
Dear Web application experts:
I am trying to use Cherrypy to do one web application. I used the cheetah template to generate the HTML file for a matrix of checkbox, and hope to return the checked checkbox information to server side. Because I already used the form for quick selection, and HTML doesn't support nested form. Could you please point me to right way to get the checked checkbox information to server side for handling?... -

How can I schedule a task to run every 10 seconds in Python?
Dear Experts:
I am writing one test program with Python which is running multiple threads in parallel. I hope to add another thread to display the test status every 10 seconds. Could you please tell me how I can schedule a task to run every 10 seconds in Python?
I defined one function return_status() and tried the Timer object of threading as follows, but it only run once after 10 seconds. I hope it can run multiple... -
Since you are using the csv module and the default line termination sequence is '\r\n', that's why you get a new line. You can try following way and it should work for you.
Code:writer.writerow(yourrow, lineterminator = '\r')

Thanks a lot!
Yes, the credit should give to both Fredrik Lundh and you!
I also tried another piece of script and merged into the original class and it also works. The script is as follows:
...Code:self.canv = Canvas ( self, width=1200, height=800, scrollregion=(0, 0, 1200, 800) ) self.canv.grid ( row=0, column=0 ) self.scrollY = ScrollbarLeave a comment:

Haiyan replied to Any idea why Tkinter scrollbar scrolls but contents on canvas didn't move together?in PythonHi, Bvdet:
You are welcome! But I still have trouble to merge into my original class definition. You know the solution I post above is to create one canvas with scrollbar, then create one frame on the canvas, then put the table of checkbox into the frame.
When I am trying to merge into my original class definition. I didn't understand the relationship of self, self.master and canvas and didn't get it implemented correctly....Leave a comment:

Thanks a lot for your help! I modified the script based on your suggestion, and looks like get it working. But I don't like the following implementation, and I hope to keep my original class definition because I need to use the scroll bar lots of places.
Following is the working code but not in class definition:
...Code:from Tkinter import * class AutoScrollbar(Scrollbar): # a scrollbarLeave a comment:

Dear experts:
I am trying to add one xy-scrollbar on the canvas, then put lots of check buttons on the canvas. I got at least following 2 problems:
1.I can see the y-scroll bar but contents on canvas didn't move together when scroll y-scrollbar.
2.The x-scrollbar didn't show up as expected.
Do you have any idea? Thank you very much in advance!
Best regards,

Dear Experts:
I made one GUI interface with Tkinter. I have some buttons on the GUI and one button is designed as "start test" which will invoke one "start test" window. I put one "ok" and one "cancel" button in this window. When I click the "ok" button it will use execfile() to call another python file which will start multiple threads to run. The multiple threads did finish but I... -

How I can use the command correctly in checkbutton?
Dear experts:

The check/uncheck...
