Change background for cell in Calendar using Python Tkinter?
To change the background color for a cell in a Calendar using Python Tkinter, you can customize the styling of the cells by overriding the default calendar
style. Here's an example that demonstrates how to change the background color for specific cells:
pythonimport tkinter as tk
from tkinter import ttk
import calendar
def set_cell_background(calendar_style, year, month, day, bg_color):
# Override the background color for the specified cell
calendar_style.map(
f"calendar_{year}_{month:02d}_{day:02d}.Cell",
background=[("", bg_color)],
)
root = tk.Tk()
# Create a calendar using the ttk.Calendar widget
calendar_style = ttk.Style()
calendar_style.theme_use('clam')
calendar_style.configure(
"calendar.TCalendar",
background='white', # Set the background color for the calendar
)
# Customize the background color for specific cells
set_cell_background(calendar_style, 2023, 6, 1, "red")
set_cell_background(calendar_style, 2023, 6, 15, "green")
calendar_widget = ttk.Calendar(root, style="calendar.TCalendar")
calendar_widget.pack()
root.mainloop()
In this example, the set_cell_background
function is used to override the background color for specific cells. The function takes the calendar_style
object, year, month, day, and the desired background color as parameters. It uses the map
method of the calendar_style
object to map a specific style element to a new background color.
By calling the set_cell_background
function with the appropriate year, month, day, and background color, you can customize the background color for specific cells in the calendar.
Note that this example assumes you are using the ttk (Themed Tkinter) module for creating the calendar. The calendar_style.map
method allows you to override the default styles for individual cells.
You can modify this example to suit your specific requirements, such as adding more customization options or changing the styling for different cells.
