A Simplified Tk Reference
--------------------------
Keyword:

toplevel
Description: Almost identical to the behavior of the frame command but it spawns a new window. This is good for message boxes and other subordinate program elements.
Example: 

proc somethinghappens {} {            
.b configure -state disabled
toplevel .t -bg yellow
label .t.l -text "Something happened!"
button .t.b -text "Ok?" -command  { destroy .t ; .b configure -state normal;}
pack .t.l .t.b }
button .b -text "Do something" -command somethinghappens
pack .b
