breaking an endles loop
- Thread starter toaran
- Start date
With wish:
set ::stop 0
pack [button .s -text Break! -command { set ::stop 1 }]
while 1 {
# this is an endless loop
if {$::stop} { break }
update
}
.s config -text stopped
The 'update' permits the button to gain control and stop the endless loop thru a global control variable.
For that, you need to use wish.
