All,

I am having a tk scrollbar widget and added a callback to the "-
command" option. In linux if click on the scrollbar arrows (up or
down) the callback is getting called recursively until i double click
outside the widget. In windows it is properly(only once) getting
called. Is there any focusing issue on linux with the scrollbar?

Any help on this will be appreciated.

Thanks,
Phani

No, there are not focusing issues on linux. Do you see the problem
with the following tiny program?

text .t -yscrollcommand [list .vsb set]
scrollbar .vsb -orient vertical -command [list .t yview]
pack .t -side left -fill both -expand true
pack .vsb -side right -fill y -expand false
.t insert end [join [info commands] \n]

If you don't see the problem with the above code, the problem is
likely in your code.
