Example text
As with progressbars, they should be given an orientation (horizontal or vertical) with the "orient"configuration option, and an 44 optional "length". You should also define the range of the number that the scale allows users to choose; to do this, set a floating point number for each of the "from" and "to" configuration options. There are several different ways you can set the current value of the scale (which must be a floating point value between the "from" and "to" values). You can set (or read, to get the current value) the scale's"value" configuration option.
Example Listboxes are one of several types of widgets that are scrollable. Here we'll build a very simple user interface, consisting just of a vertically scrollable listbox that takes up the entire window, with just a status line at the bottom. mainloop() SizeGrip •Widget Roundup •Reference Manual We actually snuck in one new widget in that last example, the sizegrip. This is the little box at the bottom right corner of the window that allows you to resize it. g. Mac OS X), Tk will automatically put the size grip there for you, it doesn't hurt to explicitly add it yourself.
Or, you can call the scale's "set value" method to change the value, or the "get" method to read the current value. There is a "command" configuration option, which lets you specify a script to call whenever the scale is changed. Tk will automatically append the current value of the scale as a parameter each time it invokes this script (we saw a similar thing with extra parameters being added to scrollbar callbacks and those on the widgets they scroll). disabled" and "instate disabled" methods if you wish to prevent the user from modifying the scale.
