Scale widgets

Scale widgets allow direct data entry of numerical data, by means of a slider. The following example creates a scale widget, and a label, and the value set by the scale widget is displayed in the label. The scale is set to show an initial value.

#Make a scale, oriented vertically, going down from 50 to 0.
     #Tick marks are places alongside the scale every 10 units.
     scale .scale1 -width 10 -orient vertical -length 280 
	    -from 50 -to 0  -command "set var1" 
	    -tickinterval 10 -relief raised

     label .lab1 -width 10 -textvariable var1 -relief sunken
     pack .scale1 .lab1 -padx 1m -pady 2m  -fill x

     #Now set the value of scale to 25 using a widget command
     .scale1 set 25
