How to refresh Tk scripts

Hi,
I have some trouble with refreshing my Tk scripts. The scripts include
some functions that last a long period of time. When they are
executed, the whole program hangs until they complete. And the user
interface is blocking.
I tried "update idletasks", but it just update after the "functions"
complete. What I need is to refresh when  the "functions"  are
execting.
I also tried "thread" and "trace", but in my opinion they didnot work.
Can anyone give me some advice? Thank you!

Regards,
zhoujingyu

Hi,
I went through the two pages, and they tell me to refresh with
"recursion" function. But I cannot make my program a recursion
function, and I have no idea how to make use of "recursion".
My program includes series of sub-functions, that is not my own code,
and packed in DLLs, thus cannot be modefied.
I try to use "recursion", such as a "clock time label" that update
automatically. And at the same time, my program is running in the same
interpreter. However it is still blocking, when a long time function
is executed. And the "clock time label" also blocks.
I'm crying for you help. Thank you!

It would be helpful if you could provide some more information about
the program.  How does your program call the functions in the DLLs
(are they in a Tcl extension?)  What do you want the GUI to do while
the functions are running?  If, in addition to answering these
questions, you could post the part of your code that calls the slow
functions, it will be easier to make meaningful suggestions.

Thanks,
Aric

Hi,Aric
It is a program to test Network devices working with SmartBits. I will
source the library(like lib.tcl), and DLLs are automatically loaded.
And now, I can use library functions, like "NSSocketLink" which is
used to connect my PC to the SmartBits. This function is called when a
"button" in my GUI is clicked, and this procedure will last a period
of time. And now the GUI is blocking. I will raise some trivial codes
later.
