Whenever we run a tkinter application, it displays a GUI-based window that would have widgets, frames, and other elements. Let us suppose we want to close our application with a function. The destroy() method in Python tkinter is used to terminate the normal execution of the application after the mainloop function.ExampleIn this example, will create a button object which triggers to close the application.#Import the tkinter library from tkinter import * #Create an instance of tkinter frame win = Tk() #Set the geometry win.geometry("650x250") #Define a function def close_app():    win.destroy() #Create a text Label Label(win, text= ...

Let us suppose we want to create a dropdown menu of a list in an application using tkinter. In this case, we can use the Tkinter OptionMenu(win, menu_to_set, options) function.First, we will instantiate an object of StringVar(), then we will set the initial value of the dropdown menu. We will create the dropdown menu by creating an object of OptionMenu and passing the value of window, menu object, and options which are to be displayed.Example#Import the required libraries from tkinter import * #Create an instance of tkinter frame win= Tk() #Define the size of window or frame win.geometry("715x250") ...

Tkinter windows can be resized automatically by hovering and pulling over the window. We can disable the resizable property using the resizable(boolean value) method. We will pass false value to this method which will disable the window to be resized.Example#Import the tkinter library from tkinter import * #Create an instance of tkinter frame win = Tk() #Set the geometry win.geometry("650x250") Label(win, text= "Hello World", font=('Times New Roman bold', 20)).pack(pady=20) #Make the window resizable false win.resizable(False, False) win.mainloop()OutputRunning the above code will display the following the tkinter window, but you won't be able to resize it.Read More

Pressing a key and handling some operation with the key is an event that can be triggered through a button. We can bind the key event using the Binding method in a tkinter application.Whenever the key will be triggered, it will call a handler that will raise the specific operation for the key event.If we want to trigger the Enter key with the bind function, we will use the bind('', Handler) method. For Enter Key, we use bind('', Handler) function.Example#Import the tkinter library from tkinter import * #Create an instance of tkinter frame win = Tk() #Set the ... Read More

To change the size of Tkinter Button in python's Tkinter library, we can use the width and height options of the Button widget in terms of text units (characters). Some common approaches We can change button size in python Tkinter by using several methods are as follows. Using Width and Height: we can set the width and height properties of the button to determine the size of the button in text units for text buttons. ... Read More

In order to change the background color and foreground color of a tkinter frame, we can assign different values to the bg and fg parameters in the Frame function.ExampleIn this example, we have created two frames with different background colors.#Import the required libraries from tkinter import * #Create an instance of tkinter frame win= Tk() #Set the geometry of frame win.geometry("650x250") #Create an frame frame1= Frame(win, bg= "red") frame2= Frame(win, bg="black") #Create an label inside the frame Label(frame2, text= "Line:1", font=('Lucida font', 20)).pack(pady=20) Label(frame1, text= "Line:2", font=('Lucida font', 20)).pack(pady=20) frame1.pack() frame2.pack() win.mainloop()OutputRunning the above ...

Tooltips are useful in applications where we need to display some information while hovering on a button.In order to create and display a tooltip, we can use the Balloon property of tkinter.Example#Import the tkinter library from tkinter import * from tkinter.tix import * #Create an instance of tkinter frame win = Tk() #Set the geometry win.geometry("600x450") #Create a tooltip tip = Balloon(win) #Create a Button widget my_button=Button(win, text= "Hover Me") my_button.pack(pady=20) #Bind the tooltip with button tip.bind_widget(my_button, balloonmsg="www.tutorialspoint.com") win.mainloop()OutputThe above code will display the following window with a button "Hover Me". When the user hovers ... Read More

Tkinter provides a custom handler to close the window. It acts as a callback function that the user can run in order to close the window.To close the window using the handler, we can use the destroy() method. It closes the window abruptly after calling it in any function or any widget. Let us invoke the close event handler by defining a method.By using as an argument in WidgetExample#Importing the required library from tkinter import * #Create an instance of tkinter frame or window win= Tk() #Set the geometry win.geometry("600x400") #Create a button and pass arguments in ...

Python provides the Pillow (PIL) package to support, process, and display the images in tkinter applications. A Tkinter application generally supports image files such as, ppm, png, and gif.Let us suppose we want to embed and display a JPEG or JPG image in our application.Tkinter Label widgets are generally used to display the text or images on the window and thus by passing the img value, we can display the JPEG image in the window.Example#Import required libraries from tkinter import * from PIL import ImageTk, Image #Create an instance of tkinter window win =Tk() #Define the geometry of ...

A Tkinter window can be initialized after running the application. Generally, the width and the height of the window is resizable which can be minimized.In order to set the window size to its minimum value, assign the value of width and height in minsize(height, width) method. The method can be invoked with the window or frame object.Example#Import the required libraries from tkinter import * #Create an instance of tkinter frame win= Tk() #Minimize the window win.minsize(150, 100) #Create a text label Label(win, text= "Window Size is minimized to 150x100", font=('Helvetica bold', 20)).pack(pady=20) win.mainloop()OutputRunning the above code ...
