Tkinter is a Python Package for creating effective GUI applications. Tkinter’s Canvas widget is nothing but a rectangular area that is used for drawing pictures, simple shapes, or any complex graph. We can place any widgets like text, button, or frames on the canvas.
The task here is to generate a Python script that can clear Tkinter Canvas. For that delete function of this module will be employed. This method has a special parameter all which represents all the component on the canvas. To clear this canvas give this special parameter to the delete method. Thus, the line below is sufficient to clear the canvas:
delete('all')
If you want to delete any specific item then you can assign a tag to that item and instead of all pass that tag to the delete method.
Given below is the code to achieve this specific functionality:
Program:
Before clearing canvas
Python3
# import tkinter from tkinter import * # make an object of Tk interface window = Tk() # Give the title to out window window.title('GFG') # creating canvas canvas = Canvas(window, width=300, height=200) canvas.pack() # draw line to out canvas canvas.create_line(0, 0, 300, 200) canvas.create_line(0, 200, 300, 0) # draw oval to out canvas canvas.create_oval(50, 25, 250, 175, fill="yellow") window.mainloop() |
Output:
Simple canvas Example
After clearing canvas
Python3
# import tkinter from tkinter import * # make an object of Tk interface window = Tk() # Give the title to out window window.title('GFG') # creating canvas canvas = Canvas(window, width=300, height=200) canvas.pack() # draw line to out canvas canvas.create_line(0, 0, 300, 200) canvas.create_line(0, 200, 300, 0) # draw oval to out canvas canvas.create_oval(50, 25, 250, 175, fill="yellow") # clear the canvas canvas.delete('all') window.mainloop() |
Output:
Cleared canvas
