In this article, we will create a GUI-based window resizer control panel that will have a pane to resize the window by its height or width.In order to create the application, we will first create a slider that will help to resize the window size. The sliders are available in the ttk library of tkinter. We will import “ttk” first. Then, we will launch a new window which needs to be resized.Let us first import all the required libraries in the notebook and design the control bars using sliders.Example# Import the required Libraries from tkinter import * from tkinter import ...

Using Tkinter.Menu, we can create menus and submenus. Also, there are some other properties which are used with tkinter menus.Tearoff property makes the menus in the window as tearable. tearoff attribute accepts a Boolean value to separate the menu from the main window or the parent window. With tearoff attribute, we have two options, If tearoff=0, make the menu stick to the Window.If tearoff=1, it display a “----” empty dotted lines on the menus through which we can separate our menu from the window.Example#Importing the tkinter library from tkinter import * win= Tk() win.title("Tearoff Example") win.geometry("600x500") #Define a Function ...

Tkinter bell() method produces the default event or dialogue sound of the system. This method can be invoked in the default window or frame. We can change the sound of the window by going to the system configuration.In this example, we will create a button that will make the default sound.Example#Import the library from tkinter import * #Create an instance of tkinter frame win= Tk() #Define the size of the window win.geometry("700x150") win.resizable(0, 0) #Define the Bell function def click():    win.bell() Button(win, text= "Click Me", command= click).pack(pady=20) win.mainloop()OutputRunning the above code will create ...

In this article, we will see how to create a functional application that calculates the ratio. In order to make it fully functional, we will use SpinBox method that generally creates an ideal spinner for a value. This value can be modified using the spinner widget in the frame. Thus, a SpinBox object takes values in the range from minimum to maximum.First, we will create a tkinter frame inside which we will define some widgets.Examplefrom tkinter import * win = Tk() win.title("Ratio Calculator") win.geometry("600x500") win.resizable(0, 0) #Create text Label for Ratio Calculator label= Label(win, text="Ratio Calculator", font=('Times New ...

Let us consider that we have a value x and we have to calculate the sum of sine(x) series. In a sine(x) series, there are multiple terms such that, sine(x) = x− x^3/fact(3) + x^5/fact(5) −x^7/fact(7)....In order to solve the particular series-based problem, we will first take the degree as the input and convert it into radian. To find out the sum of the total number of terms in this series, we will first iterate over all the given terms and find out the sum by operations.Approach to solve this ProblemTake input of Limit and degree.Iterate over the terms and ...

Let us suppose that we have a string and we have to calculate the total number of digits and letters present in the string.For ExampleInput −s = “tutorialsP0int”Output −Letters: 13 Digits: 1Explanation −Total number of letters and digits present in the given string are 13 and 1.Approach to Solve this ProblemTo calculate the total number of letters and digits in the given string, we have to first iterate over the whole string. If we get an alphabet, then we increment the letter count; otherwise, if we extract a digit, then increment the digit count.Take an input string.While iterating over the whole string, ... Read More

Tkinter provides features for adding different kinds of widgets necessary for an application. Some of these widgets are: Button widget, Entry Widget, Text Box, Slider, etc. In this article, we will see how we can create an application with a button such that it can either be on or off.In this example, we will use these two buttons for demonstration, Switch OnSwitch OffExample# Import tkinter in the notebook from tkinter import * # Create an instance of window of frame win =Tk() # set Title win.title('On/Off Demonstration') # Set the Geometry win.geometry("600x400") win.resizable(0, 0) #Create a variable ...

Sometimes we need to add unicode and special charset in our Tkinter application. We can add unicode characters in our labels or widgets concatenating the signature as, u ‘/’. You can find the list of all unicode characters from hereIn this example, we will add a unicode character in the button widget.Example# Import the required Libraries from tkinter import * #Create an instance of tkinter frame win= Tk() win.geometry("700x200") #Create a button Button(win, text='Click'+u'\u01CF', font=('Poppins bold', 10)).pack(pady=20) #Keep running the window or frame win.mainloop()OutputRunning the above code will create a button with a unicode character (u01CF).Read More

With Tkinter, we can call multiple functions at a time using Threading. It provides asynchronous execution of some functions in an application.In order to use a thread in Python, we can import a module called threading and subclass its Thread class. Inside our new class, we need to overwrite the Run method and perform our logic in there.So, basically with threading, we can do multiple work at a time. To achieve threading in our application, Tkinter provides the Thread() function.Let us take an example and create a thread which will sleep for some time and then execute another function in ...

If we will create an instance of Tkinter frame and display the window while keep running it, then it will show the default output canvas. However, we can add an image inside the Tkinter canvas as a background using PhotoImage methods and Canvas methods.Since image support in Tkinter is limited to Gif, PNG and PPM, the PhotoImage(GIF, PNG, PPM) function takes the location of the image file and displays the canvas with the image as a background.First, we will create a PhotoImage Object using the PhotoImage function.Examplefrom tkinter import * from PIL import ImageTk win = Tk() win.geometry("700x300") ...
