Luke,
Thanks for the info on configuration of
buttons.
Now as to my first question:
I am
attempting to put a stop button on a vtcl interface to halt the
execution of a routine running under vtcl, but the exit command seems to be disabled...is there any way around this? initially stopRequested is set to 0
attached by command attribute to the stop
button is:
set stopRequested 1
at a logical point in my routine, procedure
CheckStop is called
proc CheckStop
# preCondition stopRequested == 0 ~ no stop /
stopRequested == 1 ~ stop program
# postCondition exits program if stopRequested is true global widget global stopRequested update idletasks if {$stopRequested}
{
Debug 3 "stopRequested is $stopRequested"; # calls debugging procedure exit };# end if if stopRequested is true, i need the entire wish to
stop...i have routines nested in routines calling routines recursively, and need
a global break if stopRequested is set to 1
How do I do this???
If anyone knows how to accomplish this,
I would greatly appreciate your input.
Thanks,
Brent
