APIs are extremely useful in implementing a service or feature in an application. APIs help to establish the connection between the server and a client, so whenever a client sends a request using one of the API methods to the server, the server responds with a status code (201 as a successful response) to the client.You can make a request to any API you want using one of the methods (GET, POST, PUT or DELETE). However, if you want to create an application where you need a request to the server using one of the publicly available API (for example, ... Read More

If we want to implement a text editor in an application that can accept multiline user input, then we can use the Tkinter Text widget. The Text widget in Tkinter is generally used to create a text editor for an application, where we can write text and perform operations like selecting, editing and creating a specific text in the application.If you want to highlight a text and provide a color to the highlighted text, then you can use the tag_add("start", "first", "second") method. The tag_add() method takes two arguments for selecting the specified text from the text widget. You can ... Read More

In Tkinter, you can set the GUI of the application by using a different geometry manager. The grid geometry manager is one of the most useful geometry managers in tkinter that is used to set the widgets location in the application using the 2D geometry form.With a grid geometry manager, you can set a certain number of rows and columns and place the widget in any location of the application. To set a certain number of rows and columns, you’ll need to specify the size value of the row and column configuration that helps to set the location of a ... Read More

To insert a temporary text in a tkinter Entry widget, we will bind the event with the Entry widget and call a user-defined function to delete the text inside the Entry widget.Steps −Import the tkinter library and create an instance of tkinter frame.Set the size of the frame using geometry method.Create a user-defined method "temp_text()" to capture the event and delete the temporary text inside the Entry widget.Create an Entry widget inside the Root window and set its properties such as background color, width, and border width.Use the insert() method of the Entry widget to insert a string ...

We can update a Button widget in Tkinter in various ways, for example, we can change its size, change its background color, or remove its border, etc. In the following example, we will create three Button widgets and each of the buttons, upon clicking, will call a different function to update their features.Example# Import the required library from tkinter import * from tkinter import ttk # Create an instance of tkinter frame win = Tk() # Define geometry of the window win.geometry("700x300") # Function to Increase the Size of the Button def Button_Size(): button1.configure(font=('Calibri ...

We can use the and bindings to check if the CAPS Lock Key is ON or off. In the following example, we will create two user-defined functions "caps_lock_on()" and "caps_lock_off()" which will capture the event of Lock-KeyPress and Lock-KeyRelease and print the status on the screen.Example# Import required libraries from tkinter import * from tkinter import ttk # Create an instance of tkinter frame win = Tk() # Define the geometry of the window win.geometry("700x250") win.title("CAPS Lock Status") def caps_lock_on(e): label_caps.config(text="CAPS Lock is ON") def caps_lock_off(e): label_caps.config(text="CAPS ...

Let's take an example and see how to call a function using OptionMenu widget in Tkinter. In the example, we will use a StringVar object and call its get() method. A StringVar object in Tkinter can help manage the value of a widget.We will create an OptionMenu widget and fill it with a list of strings. When the user selects an option, it will invoke a function which in turn will print the selected option as a label.Steps −Import the tkinter library and create an instance of tkinter frame.Set the size of the frame using geometry method.Create a set of ...

A StringVar object in Tkinter can help manage the value of a widget such as an Entry widget or a Label widget. You can assign a StringVar object to the textvariable of a widget. For example, data = ['Car', 'Bus', 'Truck', 'Bike', 'Airplane'] var = StringVar(win) my_spinbox = Spinbox(win, values=data, textvariable=var)Here, we created a list of strings followed by a StringVar object "var". Next, we assigned var to the textvariable of a Spinbox widget. To get the current value of the Spinbox, you can use var.get().ExampleThe following example demonstrates how you can use a StringVar object in an ... Read More
