How to list available font families in Tkinter?

PythonTkinterServer Side ProgrammingProgramming

Tkinter font property is one of the most valuable properties used to customize a widget's default font. We have already seen so many fonts and used them in our widgets, but sometimes, it seems complicated to guess which font is applicable in the Tkinter library. Python Tkinter is more specific about choosing the font. We can create an application which can list all the available font in the Tkinter library.

To use the font library, we have to import it in our environment using,

from tkinter import font

There are a few steps to create this particular application,

  • Define a function and create an instance of the font by using the font.families() constructor.

  • Iterate over all the fonts and display them using the Label Widget by assigning text values with a specific font.

  • Create a canvas with a vertical scrollbar.

  • Create a frame inside the canvas where we will display all the fonts.

  • Bind the Mouse Buttons to the scroll widget that allows a scroll feature in the frame.

Example

#Import required library
from tkinter import *
from tkinter import font
#Create an instance of tkinter frame
win = Tk()
win.geometry("750x350")
win.title('Font List')
#Create a list of font using the font-family constructor
fonts=list(font.families())
fonts.sort()
def fill_frame(frame):
   for f in fonts:
      #Create a label to display the font
      label = Label(frame,text=f,font=(f, 14)).pack()
def onFrameConfigure(canvas):
   canvas.configure(scrollregion=canvas.bbox("all"))
#Create a canvas
canvas = Canvas(win,bd=1, background="white")
#Create a frame inside the canvas
frame = Frame(canvas, background="white")
#Add a scrollbar
scroll_y = Scrollbar(win, orient="vertical", command=canvas.yview)
canvas.configure(yscrollcommand=scroll_y.set)
scroll_y.pack(side="right", fill="y")
canvas.pack(side="left", expand=1, fill="both")
canvas.create_window((5,4), window=frame, anchor="n")
frame.bind("<Configure>", lambda e, canvas=canvas: onFrameConfigure(canvas))
fill_frame(frame)
win.mainloop()

Output

Executing the above code will display a window that contains a list of available fonts that Tkinter supports.
