    Prerequisite:  Python GUI – tkinter

    Python provides a Tkinter module for GUI (Graphical User Interface). In this article, we are going to see how to set text font in Tkinter.

    Text Widget is used where a user wants to insert multi-line text fields. In this article, we are going to learn the approaches to set the font inserted in the text fields of the text widget. It can be done with different methods.

    Method 1: Using a tuple and .configure( ) method.

    Approach :

    • Import the tkinter module.
    • Create a GUI window.
    • Create our text widget.
    • Create a tuple containing the specifications of the font. But while creating this tuple, the order should be maintained like this, (font_family, font_size_in_pixel, font_weight). Font_family and font_weight should be passed as a string and the font size as an integer.
    • Parse the specifications to the Text widget using .configure( ) method.

    Below is the implementation of the above approach

    Python3

    import tkinter

    root = tkinter.Tk()

    root.title("Welcome to GeekForGeeks") 

    root.geometry("400x240")

    sample_text = tkinter.Text( root, height = 10)

    sample_text.pack()

    Font_tuple = ("Comic Sans MS", 20, "bold")

    sample_text.configure(font = Font_tuple)

    root.mainloop()

    Output :

    Method 2: Setting the font using the Font object of tkinter.font

    Approach: 

    • Import the Tkinter module.
    • Import Tkinter font.
    • Create the GUI window
    • Create our text widget.
    • Create an object of type Font from tkinter.font module. It takes in the desired font specifications(font_family, font_size_in_pixel , font_weight) as a constructor of this object. This is that specified object that the text widget requires while determining its font.
    • Parse the Font object to the Text widget using .configure( ) method.

    Below is the implementation of the above approach:

    Python3

    import tkinter

    import tkinter.font

    root = tkinter.Tk()

    root.title("Welcome to GeekForGeeks") 

    root.geometry("918x450")

    sample_text=tkinter.Text( root, height = 10)

    sample_text.pack()

    Desired_font = tkinter.font.Font( family = "Comic Sans MS", 

                                     size = 20, 

                                     weight = "bold")

    sample_text.configure(font = Desired_font)

    root.mainloop()

    Output:

    In this article, we are going to learn how to change the font size of the text in Tkinter. Font size refers to how large the characters displayed on the screen are. It is crucial to use proper font size in order to gain the reader’s attention wherever needed. So let’s see the different ways using which we can change the font size of text using Tkinter.

    Method 1: Changing Tkinter font size using the font as a tuple

    import tkinter as tk
from tkinter import *

#main window
root = Tk()
#title of the window
root.title("Tkinter Font Size")

#adding a label
l = Label(root, text="This is a sample line with font size 15.", width=40,
            height=5, font=('Times New Roman', 15, 'bold'))
l.pack()

root.mainloop()

    Output:

    Font Size Tuple Output

    Font Size Tuple Output

    In the above code, we have created a very basic GUI and added a label to it. Label widgets have an inbuilt property of font(‘font family’, size, ‘font style’). Font acts as a parameter in the code above. If not mentioned explicitly, the parameters will have their default values. In the above code, we have only used the size property and set the size to 15.

    Method 2: Changing tkinter font size using the font as an object

    Recommended Read: Tkinter Font Class Tutorial 

    import tkinter as tk
from tkinter import *
import tkinter.font as tkFont

#main window
root = tk.Tk()
#title of the window
root.title("Tkinter Font Size")

#creating a font object
fontObj = tkFont.Font(size=28)

#adding a label
l = Label(root, text="This is a sample line with font size 28.",
            width=40, height=5, font=fontObj)
l.pack()

root.mainloop()

    Output:

    Font Size Object Output

    Font Size Object Output

    Here, we have created an object of the Font class named fontObj and set the font size to 28. Later, in the label, we assigned the value of parameters for the font to be equal to the font object (fontObj) and hence, in the output, the font size is 28. In addition to size, we can also mention the font family and style as required.

    Method 3: Using changing fonts using a custom class

    import tkinter as tk
from tkinter import *
from tkinter.font import Font

#creating a custom class
class cl:
    def __init__(self, master) -> None:
        self.master = master
        #setting the font size to be 40
        self.customFont = Font(size=40)
        Label(self.master, text="Font size in the custom class is 40.",
                font=self.customFont).pack()
#end of custom class

if __name__ == "__main__":
    #main window
    root = tk.Tk()
    #title of the window
    root.title("Tkinter Font Size")
    #adding a label
    l = Label(root, text="This is a sample line with default font size.",
                width=40, height=5)
    l.pack()
    #calling our class object
    customSize = cl(root)

    root.mainloop()

    Output:

    Font Size Custom Class Output

    Font Size Custom Class Output

    In the above example, we have defined a custom class (cl), inside which we have a constructor where we assign the font size to 40. A label is also created with the font parameter being equal to the customFont.

    In the main function, we first created a label with no explicit mention of the size of the text. Hence, it has the default size. After this, we call the cl class by creating its object customSize. On creating a new instance or object, the label with font size 40 is also displayed in the output along with the default size label.

    Every time a new instance of the class is created, the label with font size 40 will be displayed as it is a part of the constructor of the class here. We can also set the font family and style inside the class itself.

    Summary

    In this way, we have understood how to change the font size in Tkinter in multiple ways. It is an easy topic to understand and implement. Please check out our other Tkinter tutorials here.

    Стилизация

    Шрифты

    Последнее обновление: 24.09.2022

    Имена шрифтов

    Ряд виджетов, например, Label или Text, поддерживают установку шрифта через параметр font.
    Каждая платформа может определять свои специфические шрифты. Но также библиотека Tk по умолчанию включает ряд именнованных шрифтов, которые могут использоваться на
    различных компонентах графического интерфейса и которые доступны на всех платформах:

    • TkDefaultFont: шрифт по умолчанию, который применяется, если для виджета явным образом не определен шрифт

    • TkTextFont: шрифт по умолчанию, который применяется для виджетов Entry, Listbox и ряда других

    • TkFixedFont: шрифт с фиксированной шириной

    • TkMenuFont: шрифт для пунктов меню

    • TkHeadingFont: шрифт для заголовков в Listbox и в таблицах

    • TkCaptionFont: шрифт для строки статуса в окнах

    • TkSmallCaptionFont: шрифт малого размера для диалоговых окон

    • TkIconFont: шрифт для подписей к иконкам

    • TkTooltipFont: шрифт для высплывающих окон

    В принципе мы можем использовать эти шрифты не только в любых виджетах:

    ttk.Label(text="Hello World", font="TkTextFont")

    Tk также предоставляет дополнительный набор именнованных шрифтов, которые определены только на определенных платформах. Для их получения можно использовать
    функцию names() из пакета tkinter.font:

    from tkinter import font

for font_name in font.names():
    print(font_name)

    Например, на Windows мы получим следующий набор:

    fixed
oemfixed
TkDefaultFont
TkMenuFont
ansifixed
systemfixed
TkHeadingFont
device
TkTooltipFont
defaultgui
TkTextFont
ansi
TkCaptionFont
system
TkSmallCaptionFont
TkFixedFont
TkIconFont

    В данном случае выводятся и платформа-независимые, и платформо-специфичные шрифты, например, «system».

    ttk.Label(text="Hello World", font="system")

    Определение шрифта

    За определение шрифта в Tkinter отвечает класс Font из модуля tkinter.font. Он принимет следующие параметры:

    • name: имя шрифта

    • family: семейство шрифтов

    • size: высота шрифта (в точках при положительном значении или в пикселях при негативном значении)

    • weight: вес шрифта. Принимает значения normal (обычный) или bold (жирный)

    • slant: наклон. Принимает значения roman (обычный) или italic (наклонный)

    • underline: подчеркивание. Принимает значения True (с подчеркиванием) или False (без подчеркивания)

    • overstrike: зачеркивание. Принимает значения True (с зачеркиванием) или False (без зачеркивания)

    Для получения всех доступных семейств шрифтов на текущей платформе можно использовать функцию families() из модуля tkinter.font

    from tkinter import font

for family in font.families():
    print(family)

    Пример применения шрифтов:

    from tkinter import *
from tkinter import ttk
from tkinter import font


root = Tk()
root.title("METANIT.COM")
root.geometry("250x200")

font1 = font.Font(family= "Arial", size=11, weight="normal", slant="roman", underline=True, overstrike=True)
label1 = ttk.Label(text="Hello World", font=font1)
label1.pack(anchor=NW)

font2 = font.Font(family= "Verdana", size=11, weight="normal", slant="roman")
label2 = ttk.Label(text="Hello World", font=font2)
label2.pack(anchor=NW)

root.mainloop()

    Шрифты в Tkinter и Python

    Также можно использовать определение шрифта в виде строки:

    from tkinter import *
from tkinter import ttk

root = Tk()
root.title("METANIT.COM")
root.geometry("250x200")

label1 = ttk.Label(text="Hello World", font="Arial 11 normal roman")
label1.pack(anchor=NW)

label2 = ttk.Label(text="Hello World", font="Verdana 11 normal roman")
label2.pack(anchor=NW)

root.mainloop()

    Например, в определении "Arial 11 normal roman", применяется семейство шрифта Arial, высота 11 единиц, нежирный шрифт без наклона.

    Источник

    Метод configure виджета Tkinter Text задаёт свойства Text, подобно шрифту текста. Шрифт font может быть как tuple типом, так и объектом Tkinter Font.

    import tkinter as tk
root = tk.Tk()
root.geometry("400x240")

textExample=tk.Text(root, height=10)
textExample.pack()

textExample.configure(font=("Courier", 16, "italic"))

root.mainloop()

    textExample.configure(font=("Courier", 16, "italic"))

    Он устанавливает шрифт Courier, курсив с размером 16.

    Также мы могли бы установить шрифт с помощью объекта font модуля tkFont.

    import tkinter as tk
import tkinter.font as tkFont

root = tk.Tk()
root.geometry("400x240")

textExample=tk.Text(root, height=10)
textExample.pack()

fontExample = tkFont.Font(family="Arial", size=16, weight="bold", slant="italic")

textExample.configure(font=fontExample)

root.mainloop()

    fontExample = tkFont.Font(family="Arial", size=16, weight="bold", slant="italic")

    Преимущество использования объекта Font вместо шрифта tuple заключается в том, что один и тот же объект Font может быть присвоен различным виджетам и программно обновлен методом Font.configure. Все виджеты, имеющие один и тот же объект Font, будут обновлены в новом стиле font.

    fontExample.configure(weight='normal')

    Он обновляет вес fontExample, чтобы быть normal.

    Для вашего удобства мы перечислили все доступные семейства шрифтов в Tkinter (Tkinter 3, Windows OS). Вы также можете перечислить семейства шрифтов в вашей рабочей среде со следующими кодами,

    import tkinter as tk
import tkinter.font as tkFont

print(list(tkFont.families()))

    Tkinter actually has a variety of ways in which we may change the font type and size. Tkinter has several built in fonts, which can complicate things, especially when you realize that Each widget only uses one of these fonts. However, this also gives us the option to individually change the font type and size for different types of widgets.

    We’ll start off with a general way of changing the font size and type that effects everything in the tkinter window.

    Technique 1

    The following code will only change the Font. 

    import tkinter as tk

root = tk.Tk()
root.option_add('*Font', '19')
root.geometry("200x150")

label = tk.Label(root, text = "Hello World")
label.pack(padx = 5, pady = 5)

root.mainloop()
    CodersLegacy changing font size in Tkinter comparison

    The following code changes only the font type. Tip:

    import tkinter as tk

root = tk.Tk()
root.option_add('*Font', 'Times')
root.geometry("200x150")

label = tk.Label(root, text = "Hello World")
label.pack(padx = 5, pady = 5)

root.mainloop()
    CodersLegacy changing font type in Tkinter comparison

    Tip: If you want a list of font families, you can use the following code. It will return a list of different font types.

    from tkinter import Tk, font
root = Tk()
print(font.families())

    Finally, you can change both simultaneously by writing both at the same time.

    import tkinter as tk

root = tk.Tk()
root.option_add('*Font', 'Times 19')
root.geometry("200x150")

label = tk.Label(root, text = "Hello World")
label.pack(padx = 5, pady = 5)

root.mainloop()

    Note, however, that option_add only affects widgets created after you’ve called option_add, so you need to do it before creating any other widgets.

    Technique 2

    Here narrow down our area of effect from the whole tkinter program to certain segments of it. As mentioned earlier, tkinter has several built in fonts which different widgets use. We can change each one of these individually.

    import tkinter as tk
import tkinter.font as tkFont

root = tk.Tk()
print(tkFont.names())

    ('fixed', 'oemfixed', 'TkDefaultFont', 'TkMenuFont', 'ansifixed', 'systemfixed', 'TkHeadingFont', 'device', 'TkTooltipFont', 'defaultgui', 'TkTextFont', 'ansi', 'TkCaptionFont', 'system', 'TkSmallCaptionFont', 'TkFixedFont', 'TkIconFont')

    Above we can notice several font types like TkHeadingFont and TkMenuFont. These appear to be the fonts that determine the font type and size for headings and Menu’s respectively. Let’s try to change the TkDefaultFont. Any widget that uses the TkDefaultFont type will automatically change to the new settings.

    import tkinter as tk
import tkinter.font as tkFont

root = tk.Tk()
root.geometry("200x150")

def_font = tk.font.nametofont("TkDefaultFont")
def_font.config(size=24)

label = tk.Label(root, text = "Hello World")
label.pack(padx = 5, pady = 5)

root.mainloop()

    The tricky part however is figuring out which widgets are affected by which Font types. Due to a lack of material, this information is currently unavailable. Though you are free to search for it on your own.

    This marks the end of the change font type and size in Tkinter article. Any suggestions or contributions for CodersLegacy are more than welcome. Any questions can be asked in the comments section below.
