Anyone has idea how to insert different font size text lines to customtkinter?

[Gasiro]

Like what I used to do with tkinter: But I can't do it in customtkinter text wight now.

This is what I used to do with tkinter:

    text_widget = Text(right_frame, wrap="word", width=30, height=10, font=font.Font(size=13), padx=5, pady=5)
    text_widget.pack(fill="both", expand=True)

    now = datetime.now()
    formatted_date_time = now.strftime("%Y/%m/%d %H:%M")
    combined_font = font.Font(size=16, weight="bold")
    text_widget.tag_configure("combined_font", font=combined_font, foreground="chocolate3")
    text_widget.insert("1.0", f"📝 Fitness Rabbit Note","combined_font")
    text_widget.insert("2.0", f"\n{formatted_date_time}")
    text_widget.insert("3.0", f"\n")
    text_widget.insert("4.0", f"\n")

Use CTkTextbox. A wrapper around Tkinter's Text.

hi Dipesh, this is what I can do now, to change the color in CTkTextbox. However failed to change the individual line to different font size and not able to make individual bold or italic
` now = datetime.now()
formatted_date_time = now.strftime("%Y/%m/%d %H:%M")

# define different color
text_widget.tag_config("combined_font", foreground="chocolate3") #蓝色

# insert title and time
text_widget.insert("1.0", f"📝 Fitness Rabbit Note", "combined_font")
text_widget.insert("2.0", f"\n{formatted_date_time}")
text_widget.insert("3.0", f"\n")
text_widget.insert("4.0", f"\n")`

Got it! Let me write an example and elaborate it. Wait a little bit.

@Gasiro

customtkinter prohibits font option in Textbox widget as it considers run time scaling of the window. Scaling for different fonts in customtkinter Textbox is not handled, and if you are sure that user will not scale-up window at runtime time, then you can neglect its prohibition.

What happens is that, customtkinter checks the font parameter in tag_config method to raise an error. So, instead of passing font parameter directly, pass it in including as configuration dictionary (an especial argument provided by Tkinter).

Tkinter provides a parameter cnf (stands for configuration dictionary) using which programmar can pass all function arguments as dictionary object.

Sample code:

from customtkinter import CTkTextbox, CTkFont, CTk


app = CTk()
app.geometry("500x400")

font1 = CTkFont("Arial", 30)
font2 = CTkFont("impact", 25)
font3 = CTkFont("Georgia", 20)
font4 = CTkFont("Helvetica", 15)

tb = CTkTextbox(app)
tb.place(relx=0.5, anchor="center", rely=0.5, relwidth=1)

tb.insert("1.0", "Text example line 1.\n", "font1")
tb.insert("2.0", "Text example line 2.\n", "font2")
tb.insert("3.0", "Text example line 3.\n", "font3")
tb.insert("4.0", "Text example line 4.", "font4")


tb.tag_config("font1", cnf = {"font": font1})
tb.tag_config("font2", cnf = {"font": font2})
tb.tag_config("font3", cnf = {"font": font3})
tb.tag_config("font4", cnf = {"font": font4})

app.mainloop()

Output:

Hope, it will be helpful for you.
