Let assume that we want to call a function whenever a button or a key is pressed for a particular application. We can bind the function that contains the operation with a button or key using the bind('<button or Key>,' callback_function) method. Here, you can bind any key to the event or function that needs to be called.
In this example, we have created a function that will open a dialog box whenever we click a button.
#Import the required libraries from tkinter import * from tkinter import ttk from tkinter import messagebox #Create an instance of Tkinter Frame win = Tk() #Set the geometry of Tkinter Frame win.geometry("700x350") #Define a function for opening the Dialog box def open_prompt(): messagebox.showinfo("Message", "Click Okay to Proceed") #Create a Label widget Label(win, text= "Click to Open the MessageBox").pack(pady=15) #Create a Button for opening a dialog Box ttk.Button(win, text= "Open", command= open_prompt).pack() win.mainloop()
Running the above code will display a window containing a label and a button.
Upon clicking the "Open" button", it will call a function to open a dialog box.
