font1=To one of the option we can assign the font style like this. def my_upd(col): if col='white': nfigure('Treeview',background='white', fieldbackground='white', foreground='black') elif col='yellow': nfigure('Treeview',background='yellow', fieldbackground='yellow', foreground='black') else: nfigure('Treeview',background='black', fieldbackground='black', foreground='white')We can include the font style also.

r1 = tk.Radiobutton(my_w, text='Black', variable=r1_v, value='black', command=lambda:my_upd('black'))Inside the function my_upd() we will check the parameter value and accordingly update the style. On click of the radio button we will trigger the function my_upd(col) and we passed colour as parameter. We used on StringVar() with default value as 'black'. nfigure('Treeview', rowheight=100) Managing style using Radio buttonsUsing three RadioButtons we will configure the style of Treeview. style = ttk.Style(my_w) style.theme_use('clam') # set theam to nfigure('Treeview', background='black', fieldbackground='black', foreground='white')nfigure('Treeview.Heading', background='PowderBlue')The last line in above code adds different background color to headings.

Assigning default style for TreeviewThis is applied to all Treeview widgets.
