Tkinter Message Widget Example
Below we have a basic example for the Tkinter Message widget:
from tkinter import *
win = Tk()
win.geometry("300x200")
w = Label(win, text ='StudyTonight', font = "90",fg="Navyblue")
w.pack()
msg = Message(win, text = "Best place to learn coding online")
msg.pack()
win.mainloop()
In the code example above, we have created a simple label widget and a message widget with some text message in it.
Summary:
So with this, we have covered the Tkineter Message Widget which is used to show message in Tkinter GUI application. We can also create message widget dynamically to show error or success message in Tkinter application.
