The Scale widget is used whenever we want to select a specific value from a range of values. It provides a sliding bar through which we can select the values by sliding from left to right or top to bottom depending upon the orientation of our sliding bar.
Syntax:S = Scale(root, bg, fg, bd, command, orient, from_, to, ..)
Optional parameters- root - root window.
- bg - background colour
- fg - foreground colour
- bd - border
- orient - orientation(vertical or horizontal)
- from_ - starting value
- to - ending value
- troughcolor - set colour for trough.
- state - decides if the widget will be responsive or unresponsive.
- sliderlength - decides the length of the slider.
- label - to display label in the widget.
- highlightbackground - the colour of the focus when widget is not focused.
- cursor - The cursor on the widget which could be arrow, circle, dot etc.
Methods- set(value) - set the value for scale.
- get() - get the value of scale.
Example 1: Creating a horizontal bar
Python3 1==# Python program to demonstrate# scale widgetfromtkinterimport*root=Tk()root.geometry("400x300")v1=DoubleVar()defshow1():sel="Horizontal Scale Value = "+str(v1.get())l1.config(text=sel,font=("Courier",14))s1=Scale(root,variable=v1,from_=1,to=100,orient=HORIZONTAL)l3=Label(root,text="Horizontal Scaler")b1=Button(root,text="Display Horizontal",command=show1,bg="yellow")l1=Label(root)s1.pack(anchor=CENTER)l3.pack()b1.pack(anchor=CENTER)l1.pack()root.mainloop()
Output:
Example 2:Creating a vertical slider
Python3 1==fromtkinterimport*root=Tk()root.geometry("400x300")v2=DoubleVar()defshow2():sel="Vertical Scale Value = "+str(v2.get())l2.config(text=sel,font=("Courier",14))s2=Scale(root,variable=v2,from_=50,to=1,orient=VERTICAL)l4=Label(root,text="Vertical Scaler")b2=Button(root,text="Display Vertical",command=show2,bg="purple",fg="white")l2=Label(root)s2.pack(anchor=CENTER)l4.pack()b2.pack()l2.pack()root.mainloop()
