Tkinter is a standard Python library that is used to create and develop functional and featured applications. It has a variety of inbuilt functions, modules, and packages that can be used for constructing the logic of the application.The tkFileDialog is an inbuilt module available in the Tkinter library which is useful for interacting with the system files and directories. However, once we select a particular file in the read mode using tkFileDialog, potentially it can be used further to process the information available in the file.If you want to access the absolute path of the file when it gets loaded in ...

To display a large set of data in a Tkinter application, we can use the Treeview widget. Generally, we represent data through tables that contain a set of rows and columns. We can add the data in the form of a table with the help of the Treeview widget.To configure the column width of the Treeview widget, we can use the width and stretch property. It sets the width of the Treeview widget column with the given value.ExampleIn this example, we have created a table that contains a list of programming languages. The width of columns ‘ID’ and ‘Programming Language’ is set ... Read More

In order to create buttons in a Tkinter application, we can use the Button widget. Buttons can be used to process the execution of an event in the runtime of an application. We can create a button by defining the Button(parent, text, **options) constructor.Let us suppose we want to create a Browse Button which when clicked, will ask the user to select a file from the system explorer. To create a dialog box for selecting a file, we can use filedialog package in tkinter library. We can import the filedialog in the notebook using the following command, from tkinter import filedialogOnce the package ... Read More

Tkinter offers Listbox widgets which is very useful in the case of representing a large set of data items in the form of a list. To configure the listbox widget, we can use configure(*options) method to change the properties such as background color, foreground color, and other properties of the listbox widget. The width property is used to define the width of the listbox widget. If we set width=0, then it will get closed to the length of its content in the listbox.Example# Import the required libraries from tkinter import * # Create an instance of tkinter frame or window ...

Tkinter is a cross-platform tk GUI toolkit based on Python library which is used to create and develop GUI-based applications. Tkinter application can be bundled in an executable or runnable file which enables the application to run without using Python interpreter or IDLE. The need for bundling an application becomes a priority when the user wants to share the application with other people without sharing the piece of code.Python has a variety of modules and extensions that gives access to the user to convert a running application into an executable, portable file. Each file runs on a different platform; thus, ... Read More

To render widgets in a Tkinter application, we generally use mainloop() function which helps to display the widgets in a window. In many cases, tkinter window displays over the other windows or programs. While switching to other programs or windows, it seems difficult to find and switch back to the Tkinter window again.We can force our tkinter window to stay on Top of other window or programs by creating a function and defining win.lift() method in a loop. In the loop, it will execute win.after(2000, function()) function to ensure that the tkinter window will always stays on top of other windows.Example# Import ... Read More

Tkinter text widget can be configured by using the configure(**options) function. We can use it to configure the background color, foreground color, wrapping and other properties of the text widget.The wrap properties of the Text widget describe that the cursor changes its position whenever it detects a new line. However, in Tkinter, the text widget can be wrapped by words and characters. In order to make our text widget to stay in one line, we can use wrap=None property.Example# Import the required libraries from tkinter import * import lorem # Create an instance of tkinter frame or window win=Tk() ...

Tkinter Listbox widgets are very useful in the case of representing a large set of data items in form of list items. To configure the properties such as change the background color of the entire Listbox, we can use configure(**options) method to change the properties of the Listbox widget.Example# Import the required libraries from tkinter import * # Create an instance of tkinter frame or window win=Tk() # Set the size of the window win.geometry("700x350") # Add a Listbox widget with number as the list items listbox =Listbox(win) listbox.insert(END, "C++", "Java", "Python", "Rust", "GoLang", "Ruby", "JavScript", "C# ", ...

Let us suppose that a Tkinter application has widgets placed in the window using the Grid Geometry Manager. In order to change the properties of the Tkinter widgets, we can use configure(**options) method. While rendering the widgets in the window, we have to assign the constructor to a variable that gives access to change the widget’s property globally.Example# Import the required libraries from tkinter import * # Create an instance of tkinter frame or window win=Tk() # Set the size of the window win.geometry("700x350") # Add a Label widget and assign it to a new variable label=Label(win, ...

Tkinter is a standard Python library which is used to create GUI-based applications. To create a simple moving ball application, we can use the Canvas widget which allows the user to add images, draw shapes, and animating objects. The application has the following components, A Canvas widget to draw the oval or ball in the window.To move the ball, we have to define a function move_ball(). In the function, you have to define the position of the ball that will constantly get updated when the ball hits the canvas wall (left, right, top, and bottom).To update the ball position, we ...
