Popup window in Tkinter can be created by defining the Toplevel(win) window. A Toplevel window manages to create a child window along with the parent window. It always opens above all the other windows defined in any application. We can create a top-level window or a child window by initializing the object of Toplevel(parent). It inherits all the property of its parent window, such as geometry, title, and width or height.ExampleIn this example, we will create a button that will open a Popup window above all the other windows.#Import the required Libraries from tkinter import * from tkinter import ttk ...

To find the minimum height and width of canvas items, we can use the bounding box property of Canvas. Basically, a bounding box property enables the canvas item to return the position inside the canvas. Initially, every item in the bbox(item) method defines the minimum and maximum width and height of the item.Example#Import required libraries from tkinter import * #Create an instance of tkinter frame win= Tk() #Define the geometry of the window win.geometry("750x250") #Initialize a Canvas canvas= Canvas(win, width= 600, height= 200) #Add a text inside the Canvas text= canvas.create_text(300, 20, text= "This is a New Line Text", font=16, ...

Tkinter Scale Widgets are used to provide the visual representation of data items where we can modify or change the value of data items. In order to change the state of data or select multiple data in the field, we can use the Scale widget.The Scale Widget can be created by initializing a Scale(parent, from_, to, orient, options) constructor.However, sometimes we need to set the default value of the Tkinter Scale widget, which can be set by using the set(numeric_value) method.ExampleIn this example, we will create a scale widget that sets a default value for the slider.#Import the required Libraries ...

Tkinter generally provides three general ways to define the geometry of the widgets. They are − Place, Pack, and Grid Management. If we use the Pack geometry manager, then place the two buttons in the frame using side property. It places the buttons horizontally stacked in the window in (Left, Right, Top and Bottom) direction. The side property maintains the same width and internal padding between all the adjacent widget in the application.Example#Import the required Libraries from tkinter import * from tkinter import ttk import random #Create an instance of Tkinter frame win = Tk() #Set the geometry of Tkinter frame ...

Tkinter Entry widget is used to insert single-line text input. We can use the Entry widget to create forms where single-line input is the prime requirement.Sometimes, we need to insert a predefined text inside the Entry Widget. In such cases, we can use insert(INSERT, ) method. These are generally called as Placeholders for the Entry widget.Let us suppose that we want to change the state of our text as read-only. Here, we can use state= ‘readonly’ property while configuring the Entry widget.Example#Import the required Libraries from tkinter import * from tkinter import ttk #Create an instance of tkinter frame win = ...

An Entry widget is a basic one-line character widget that supports only single-line text input. An Entry widget can be defined by initializing the Entry(parent, width) constructor.To validate the Entry widget, we can use the get() method which results in the character entered in the Entry widget.Let us define an Entry widget that accepts single-line text input, and we will print the character that is input in the Entry widget.Example#Import the required Libraries from tkinter import * from tkinter import ttk #Create an instance of Tkinter frame win = Tk() #Set the geometry of Tkinter frame win.geometry("750x250") def get_content(): ...

Tkinter Listbox widgets are used to display a scrollable list of items with vertically stacked menus. Sometimes, we may need to set the list item selected, by default. We can use the select_set(list_item_index) method by specifying the index of the list items that need to be selected by default.So, let us suppose that we have a list of programming languages in our Listbox and what we want is to set the first item selected, then we can provide the index of a first list item in the method. The method must be invoked before the end of mainloop() function.Example#Import tkinter ... Read More

A Button can be initialized using the for loop in a Tkinter application. Let us suppose that we want to create multiple buttons, each with different commands or operations defined in it. We have to first initialize the Button inside a for loop. The iterator will return the object for which multiple instances of the button will be created.ExampleIn this example, we will define some buttons that will have different commands or functionalities.#Import the required Libraries from tkinter import * from tkinter import ttk #Create an instance of Tkinter frame win = Tk() #Set the geometry of the Tkinter frame win.geometry("750x250") ...

Let us suppose that we want to create a standalone app (executable application) using tkinter. We can convert any tkinter application to an exe compatible file format using the PyInstaller package in Python.To work with pyinstaller, first install the package in the environment by using the following command, pip install pyinstallerOnce installed, we can follow the steps to convert a Python Script File (contains a Tkinter application file) to an Executable file.Install pyinstaller using pip install pyinstaller in Windows operating system. Now, type pyinstaller --onefile -w filename and press Enter.Now, check the location of the file (script file) and you will ... Read More
