キャンバスに画像を追加する:
self.image_on_canvas = self.canvas.create_image(0, 0, image = ...)
キャンバス上の画像の変更:
self.canvas.itemconfig(self.image_on_canvas, image = ...)
完全な例:
from Tkinter import *
#----------------------------------------------------------------------
class MainWindow():
#----------------
def __init__(self, main):
# canvas for image
self.canvas = Canvas(main, width=60, height=60)
self.canvas.grid(row=0, column=0)
# images
self.my_images = []
self.my_images.append(PhotoImage(file="ball1.gif"))
self.my_images.append(PhotoImage(file="ball2.gif"))
self.my_images.append(PhotoImage(file="ball3.gif"))
self.my_image_number = 0
# set first image on canvas
self.image_on_canvas = self.canvas.create_image(0, 0, anchor='nw', image=self.my_images[self.my_image_number])
# button to change image
self.button = Button(main, text="Change", command=self.onButton)
self.button.grid(row=1, column=0)
#----------------
def onButton(self):
# next image
self.my_image_number += 1
# return to first image
if self.my_image_number == len(self.my_images):
self.my_image_number = 0
# change image
self.canvas.itemconfig(self.image_on_canvas, image=self.my_images[self.my_image_number])
#----------------------------------------------------------------------
root = Tk()
MainWindow(root)
root.mainloop()
