We can customize the Tkinter widget by modifying the value of its properties such as font-family, text-size, text-size, width, the height of the frame, etc. Tkinter Text widgets are generally used for accepting multiline user input. It is similar to a standard text widget.To configure the text properties of the a widget, we can use the font(‘font-family font-size font-style) attribute by defining its font-family, font-size, and the font style.Example#Import tkinter library from tkinter import * #Create an instance of Tkinter frame or window win= Tk() #Set the geometry of tkinter frame win.geometry("750x250") #Create a Text widget text= Text(win, width= 60, ...

As the name suggests, a grid is nothing but a set of rows and columns. Tkinter grid manager works similarly; it places the widget in a 2-dimensional plane to align the device through its position vertically and horizontally.Let us consider an example where we want to make the widget centered in the window while resizing it. The grid(row, column) property will help to make the label widget centered horizontally, and the sticky property will avoid resizing the widget in the window.Example#Import tkinter library from tkinter import * #Create an instance of Tkinter frame or window win= Tk() #Set the geometry ...

There are several ways to disable and enable a particular widget in a Tkinter application. However, if we want to control the Tkinter window components such as mouse cursor, control icons, toolbars, then Tkinter provides several built-in functions which can be used to configure the Tkinter window objects.To hide or disable the mouse pointer for a particular Tkinter application, then we can configure the mouse property using config(mouse= "none") method. It can be invoked for the master or root window.Example#Import tkinter library from tkinter import * from tkinter import ttk #Create an instance of Tkinter frame or window win= Tk() ... Read More
We can load the images in a Tkinter application using the PhotoImage(image location) function, which takes the image location as the parameter and displays the image on the window object. However, when we try to add an image to the button, it generally appears on the button while hiding the button text. Therefore, to make the button text and pictures relative to each other, we typically use the compound property. It takes one of four positional arguments – LEFT, RIGHT, TOP, and BOTTOM, each defining the image’s position on the button.ExampleIn this example, we have used this image to make ... Read More
Unlike other Python libraries, Tkinter has many features that are used to create a full-fledged application. It supports multiple window operations and threading for processing the operation on Windows.Following the thread, we will create an application that will pull the data from root window and put it into a child window. The concept of child window can be referred to as Dialog Boxes which present some information to the user during the happening of an event. The child window in Tkinter is created very easily by using Toplevel(root) constructor.ExampleIn this example, we will create an entry widget along with a ... Read More
In order to make a Tkinter window borderless and full-screen, we can use the utility method attributes(‘-fullscreen’, True). Tkinter windows can be configured using functions and methods defined in the Tkinter library.Another similar method Tkinter provides to make the application window full-screen is, overrideredirect(True). This method can be invoked only if the application needs to resize in its defined width and height only.Example#Import the required Libraries from tkinter import * #Create an instance of Tkinter frame win= Tk() #Set the Geometry win.geometry("750x250") #Full Screen Window win.attributes('-fullscreen', True) def quit_win(): win.destroy() #Create a Quit Button button=Button(win, text="Quit", font=('Comic Sans', 13, ...

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") ...

ProblemWe are required to write a JavaScript function that takes in array of strings, arr, as the first argument and an array of special characters, starters, as the second argument.The starter array contains characters that can start a comment. Our function should iterate through the array arr and remove all the comments contained in the strings.For example, if the input to the function is:const arr = [ 'red, green !blue', 'jasmine, #pink, cyan' ]; const starters = ['!', '#'];Then the output should be −const output= [ 'red, green', 'jasmine, ' ];ExampleFollowing is the code − Live Democonst ...

Build UpSuppose we have the following array in JavaScript −const arr = [4, 3, 4, 7, 5, 2, 3, 4, 3, 2, 3, 4];If we plot the points of this array on y-axis with each adjacent point being unit distance away on x-axis, the graph will look like this −This graph clearly shows that there exist two local maxima (peaks) in this array at index 3 and 7 with values 7 and 4 respectively.ProblemWe are required to write a JavaScript function that takes in an array of integers, arr, as the first and the only argument.Our function is supposed to ...

ProblemWe are required to write a JavaScript function that takes in a number, num, as the first and the only argument.Our function should find and return a number such that it contains only and all the digits of the input number and is just bigger than the input numberIf there exists no such number, our function should return -1.For example, if the input to the function is −const num = 5656;Then the output should be −const output = 5665;Output ExplanationBecause 5665 contains only and all digits of 5656 and is just greater than 5656.ExampleFollowing is the code &mius; Live Democonst num ...
