Hi All,
I am trapped by these two funny things: class MyClass(upClass): def start(self): ***do_menu_here**** self.load_label_image() # ---> this works self.load_canvas_image() # ---> this does not work def load_label_image(self): img = PhotoImage(file="xx.gif") Label(self, image=img).pack(side=BOTTOM, expand=YES, fill=BOTH) return img def load_canvas_image(self): img = PhotoImage(file="xx.gif") self.canvas = Canvas(self, width=500, height=300, bg='white') self.canvas.pack(expand=YES, fill=BOTH) self.canvas.create_image(50, 0, image=img, anchor=NW) if __name__ == '__main__': root = Tk() root.mainloop() load_label_image() works. However, I cannot do BIND with it, because img has no method to do binding. So, I am trying load_canvas_image. Surprise, it does not work. These two defs are so similar, but Python complained that no attribute of load_canvas_image(). It is there, coexisting with load_label_image(). I cannot figure out what is wrong with it, can somebody tell me why? Thanks! -- https://mail.python.org/mailman/listinfo/python-list
