⁠delete list items with animation effect in tkinter

Description: Deleting List Items with Animation in Tkinter

Objective

The goal is to create a visual effect that animates the removal of list items in a Tkinter widget. This enhances the user experience by making item removal appear more dynamic and visually appealing.

To create a Tkinter application that prints the list of available fonts with an animation effect, you can use the ‘tkinter.font' module to get the available fonts and display them in the console with a delay between each print.

• Create a Tkinter Listbox and populate it with some items.
• Define a function to delete items with an animation effect.
• Use the after method to repeatedly call the deletion function, giving the appearance of an animation.

  import tkinter as tk
  
  # Function to delete list items with animation
  def delete_items_with_animation(listbox):
      # Get the number of items in the listbox
      num_items = listbox.size()
      
      # Define the inner function for the animation
      def animate_delete(index):
          if index < num_items:
              # Delete the item at the current index
              listbox.delete(index)
              # Schedule the next deletion
              listbox.after(100, animate_delete, index)
          else:
              # End of deletion, stop the animation
              return
      
      # Start the animation from the first item
      animate_delete(0)
  
  # Create the main window
  root = tk.Tk()
  root.title("Listbox Animation Example")
  
  # Create a Listbox widget
  listbox = tk.Listbox(root)
  listbox.pack(pady=20)
  
  # Populate the Listbox with items
  items = ["Item 1", "Item 2", "Item 3", "Item 4", "Item 5"]
  for item in items:
      listbox.insert(tk.END, item)
  
  # Create a Button to trigger the deletion with animation
  delete_button = tk.Button(root, text="Delete with Animation", command=lambda: delete_items_with_animation(listbox))
  delete_button.pack(pady=10)
  
  # Start the Tkinter main loop
  root.mainloop()
  

  • The delete_items_with_animation function starts the animation by calling animate_delete(0), which deletes the first item.
  • The animate_delete function deletes the item at the current index and schedules the next deletion using after.
  • The after method is used to delay the deletion of each item by 100 milliseconds, creating a simple animation effect.

  You can adjust the delay in the after method to make the animation faster or slower.
