Tkinter provides Button widgets to create a button for triggering an event. Let us suppose we have created a button that is already disabled in an application. In order to change the state of the button, we can use the state property.The state property is used to enable and disable a button in an application. In order to change the state of the application, we have two operations: state=DISABLED and state=NORMAL.Example#Import the required libraries from tkinter import * #Create an instance of tkinter frame win= Tk() #Set the geometry of frame win.geometry("650x450") #Define a function for Button ...

Tkinter Treeview widgets are used to display the hierarchy of the items in the form of a list. It generally looks like the file explorer in Windows or Mac OS.Let us suppose we have created a list of items using treeview widget and we want to clear the entire treeview, then we can use the delete() function. The function can be invoked while iterating over the treeview items.ExampleIn this example, we will create a treeview for the Programming Language and will clear the list of items using delete() operation.#Import the required library from tkinter import * from tkinter import ttk ...

Tkinter frames are used to group and organize too many widgets in an aesthetic way. A frame component can contain Button widgets, Entry Widgets, Labels, ScrollBars, and other widgets.If we want to clear the frame content or delete all the widgets inside the frame, we can use the destroy() method. This method can be invoked by targeting the children of the frame using winfo_children().Example#Import the required libraries from tkinter import * #Create an instance of tkinter frame win= Tk() #Set the geometry of frame win.geometry("600x250") #Create a frame frame = Frame(win) frame.pack(side="top", expand=True, fill="both") #Create a ...

Tkinter Text Widget is used to add the text writer in an application. It has many attributes and properties which are used to extend the functionality of a text editor. In order to delete the input content, we can use the delete("start", "end") method.Example#Import the tkinter library from tkinter import * #Create an instance of tkinter frame win = Tk() #Set the geometry win.geometry("600x250") #Define a function to clear the input text def clearToTextInput():    my_text.delete("1.0", "end") #Create a text widget my_text=Text(win, height=10) my_text.pack() #Create a Button btn=Button(win, height=1, width=10, text="Clear", command=clearToTextInput) btn.pack() #Display ...

Tkinter Entry widgets are used to display a single line text that is generally taken in the form of user Input. We can clear the content of Entry widget by defining a method delete(0, END) which aims to clear all the content in the range. The method can be invoked by defining a function which can be used by creating a Button Object.ExampleIn this example, we have created an entry widget and a button that can be used to clear all the content from the widget.#Import the required libraries from tkinter import * #Create an instance of tkinter frame ...

Tkinter provides a way to add a canvas in a window and when we create a canvas, it wraps up some storage inside the memory. While creating a canvas in tkinter, it will effectively eat some memory which needs to be cleared or deleted.In order to clear a canvas, we can use the delete() method. By specifying “all”, we can delete and clear all the canvas that are present in a tkinter frame.Example#Import the tkinter library from tkinter import * #Create an instance of tkinter frame win = Tk() #Set the geometry win.geometry("650x250") #Creating a canvas myCanvas =Canvas(win, ...

Tkinter initially creates a window or frame that contains widgets and Labels within it. Let us suppose we want to close the tkinter window with a button. A Button is a UI widget that can be used to perform a certain operation.ExampleHere, we will create a button that closes the tkinter window. In order to close and terminate the TCL interpreter, we mainly use the destroy() method.#Import the required libraries from tkinter import * #Create an instance of tkinter frame win= Tk() #Set the geometry of frame win.geometry("600x250") #Create a Label Label(win, text="Press the Close Button to ...

Let’s suppose that we are creating an application which interacts with sources and files such as downloading the files, tracking the file. In order to make a progressbar for such an application, we will use the tkinter.ttk package that includes the Progressbar module.Initially, we will instantiate an object of Progressbar which has orientation of Horizontal. Then, we will define a function to increase the value of the progressbar and keep updating it.ExampleIn the following example, we have created a download progress bar by updating its value.#Import the required libraries from tkinter import * from tkinter.ttk import * import time ...

Let us suppose that we want to create an Entry widget that supports multiline user input. In order to create a multiline Entry widget, we can use Text() constructor.ExampleHere, in this example, we will create a window that contains a multiline Entry widget.#Import the library from tkinter import * #Create an object of tkinter window or frame win = Tk() #Define the geometry of window win.geometry("650x250") #Create an instance of Text Widget text = Text(win) text.pack() win.mainloop()OutputRunning the above code will display a window with a text widget that supports multiline user Input.

Let us suppose we want to add an Entry widget which accepts user passwords. Generally, the passwords are displayed using “*” which yields to make the user credentials in an encrypted form.We can create a password field using tkinter Entry widget.ExampleIn this example, we have created an application window that will accept the user password and a button to close the window.#Import the required libraries from tkinter import * #Create an instance of tkinter frame win= Tk() #Set the geometry of frame win.geometry("600x250") def close_win():    win.destroy() #Create a text label Label(win, text="Enter the Password", font=('Helvetica', ...
