How can I resize the root window in Tkinter?
In this example, we will see how to resize a tkinter window using the geometry manager. Tkinter geometry manager is generally used to configure the width and height of a tkinter window. The geometry(width x height) method takes width and height as parameters and resizes the window accordingly. We can also define the position of the tkinter window by adding geometry("width x height+X+Y") where X and Y are horizontal and vertical positions of the window. Basic Window Resizing Here's how to create and resize a tkinter window ? # Import tkinter library from tkinter import ...
Read MoreGet the text of a button widget in Tkinter
When building Tkinter applications, you may need to retrieve the text content of a button widget dynamically. The cget() method allows you to get configuration values from any Tkinter widget, including button text. Syntax The basic syntax to get button text is − button_text = button.cget('text') Example Let's create a button and retrieve its text to display in a label widget − # Import tkinter library from tkinter import * from tkinter import ttk # Create an instance of tkinter frame or window win = Tk() # Set the ...
Read MoreGet Application Version using Python
In software development, whenever developers add new features or fix bugs in an application, they assign it a new version number. This helps users identify the latest updates and features available in that application. Using Python, we can retrieve the version of any application installed on Windows systems. We'll use the pywin32 library to interact with executable files through the Win32 API, which provides access to Windows system information. Installation First, install the required package ? pip install pywin32 Getting Application Version Here's how to retrieve the version number of any Windows ...
Read MoreDisable Exit (or [ X ]) in Tkinter Window
The window manager implements the Tkinter window control icons. To hide and show the Tkinter window control icons, we can use the built-in protocol() function, which describes whether we want to disable control icons' functionality. To disable the Exit or [X] control icon, we have to define the protocol() method. We can limit the control icon definition by specifying an empty function for disabling the state of the control icon. Syntax window.protocol("WM_DELETE_WINDOW", callback_function) Where: WM_DELETE_WINDOW - Protocol for window close event callback_function - Function to handle the close event (use empty function to ...
Read MoreCreating Tkinter full-screen application
Tkinter initially creates a window that contains application components such as widgets and control bars. We can switch a native-looking application to a full-screen application by using the attributes('-fullscreen', True) method. To make the window full-screen, just invoke the method with the particular window. Basic Full-Screen Example Here's how to create a basic full-screen Tkinter application ? # 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 = Label(win, ...
Read MoreConvert Images to PDFs using Tkinter
Python is a scripting language that helps create various file converters. Using the img2pdf module and Tkinter, we can build a GUI application that converts multiple images into PDF format. The img2pdf library efficiently parses image data and converts it to PDF without quality loss. Installation First, install the required module ? pip install img2pdf Building the Image to PDF Converter We will create a Tkinter application with file selection dialog and conversion functionality ? from tkinter import * from tkinter import filedialog, messagebox from tkinter import ttk import img2pdf import ...
Read MoreChange command Method for Tkinter Button in Python
The Button widget in Tkinter is crucial for handling events and performing operations in GUI applications. Sometimes you need to change what a button does after it's been created and displayed. To change a button's command method after initialization, use the configure() method. This allows you to reassign the button's functionality dynamically during program execution. Syntax button.configure(command=new_function) Example Here's a complete example showing how to change a button's command method ? # Import tkinter library from tkinter import * # Create an instance of tkinter frame win = Tk() ...
Read MoreDifference between tkinter and Tkinter
The main difference between Tkinter and tkinter is the Python version compatibility. Tkinter (capital T) was used in Python 2, while tkinter (lowercase t) is used in Python 3 and later versions. Python 2 vs Python 3 Import Syntax In Python 2, the tkinter module was named with a capital T ? from Tkinter import * In Python 3 and later, the module name uses lowercase ? from tkinter import * Example: Python 3 Error with Capital T If you try to use the old Python 2 syntax in ...
Read MoreDisplay message when hovering over something with mouse cursor in Tkinter Python
Let us suppose we want to create an application where we want to add some description on Tkinter widgets such that it displays tooltip text while hovering on the button widget. It can be achieved by adding a tooltip or popup. Tooltips are useful in applications where User Interaction is required. We can define the tooltip by instantiating the constructor of Balloon(win) from tkinter.tix. After that, we can bind the button with the tooltip message that applies on the widget. Using tkinter.tix for Tooltips The tkinter.tix module provides the Balloon widget for creating tooltips. Here's how to ...
Read MoreDraw a circle in using Tkinter Python
Tkinter Canvas widget provides built-in methods for creating various shapes including circles, rectangles, triangles, and freeform shapes. To draw a circle, we use the create_oval() method with specific coordinates. Syntax The basic syntax for creating a circle using create_oval() method is ? canvas.create_oval(x0, y0, x1, y1, options) Parameters x0, y0 ? Top-left corner coordinates of the bounding rectangle x1, y1 ? Bottom-right corner coordinates of the bounding rectangle options ? Additional styling options like fill, outline, width Example − Basic Circle Here's how to create a simple circle using ...
