I guess it's blocking because it keeps on running the "while" loop for
a long time. That's not the way to go. In fact, TCL is not multi
threaded, but event driven. So, the TCL/Tk interpreter has its own
loop (the event loop) to wait for things to happen. If you're waiting
for something to change in that loop, you don't allow the TCL
interpreter to get into the event loop. So, the command in the "after
10000 do_something" will probably never execute.
A better approach would be to check if the condition is true
periodically. Something like:
::MSN::changeStatus "NLN"
a lot of things ...
after 10000 do_something
after 1000 check_timeout
proc do_something {} {
...
}
proc check_timeout {} {
if {!SOMETHING} {
a few things
::MSN::changeStatus "BSY"
after 1000 check_timeout
}
}
Or you could also take a look to "vwait" command. That should allow
tcl/tk to enter the event loop and continue running your code after
the specified variable has changed. But be careful, as it might
prevent other code from running and lead to deadlocks.

2006/5/21, Salatiel Filho <[EMAIL PROTECTED]>:
i have added a new item on help menu , that calls one of my plugin's
methods.
But when i click it , amsn freezes until the plugin executes , that take a
little time , because i have at least 1 "after 10000"
My plugin method method is something like:
while something [it will execute at most 3 times] {
::MSN::changeStatus "NLN"
a lot of things ...
after 10000
a few things
::MSN::changeStatus "BSY"
}
any help ?
