Question

我一直在做一个井字游戏项目，我打算创建9个按钮小部件，每个小部件都有一张图片。我想移动他们，所以他们将在一条线上连续3次。这是我的代码：

#imports:
from Tkinter import *
from PIL import ImageTk, Image

#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#constants
#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#classes:
class App(Frame):
    def __init__(self, master=None):
        Frame.__init__(self, master)
        self.pack()
#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
myapp = App()

class GUI:
    def __init__(self):
        self.myapp = myapp
        self.myapp.master.title("tkname")
        self.myapp.master.maxsize(2000, 1200)

    def create_and_pack_canvas(self, game_board_height, game_board_width):
        canvas = Canvas(height = game_board_height, width = game_board_width)
        canvas.pack(expand=1, fill=BOTH)
        return canvas

    def form_game_board(self):
        x = 404
        y = 150
        canvas = self.create_and_pack_canvas(1000, 1000)

        for i in range(3):
            for j in range(3):
                btn = gameButton("")
                btn.create_and_pack(canvas, x, y)
                x += 200
            x = 404
            y += 208

        self.myapp.mainloop()
#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
class gameButton:
    def __init__(self, picture_param):
        self.picture = ImageTk.PhotoImage(Image.open("somepic"))
        self.picture_height = self.picture.height()
        self.picture_width = self.picture.width()

    def callback(self):
        print 10

    def create_and_pack(self, canvas, x_pixels, y_pixels):
        self.b = Button(myapp, text="Print 10~", command = self.callback, image = self.picture)
        self.b.pack()
        #self.b.place(bordermode = OUTSIDE, x = x_pixels, y = y_pixels)

    def __str__(self):
        pass
#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#main
def main():
    gui = GUI()
    gui.form_game_board()

if __name__ == "__main__":
    main()

请注意这一行：

#self.b.place(bordermode = OUTSIDE, x = x_pixels, y = y_pixels)

在代码中，我把它作为一个注释，它基本上是应该移动按钮的行。如果你运行代码，它只会将所有按钮一个接一个地放在另一行中，其中9个。在self.b.place（）行之后，它们都消失了。也许他们搬到了某个地方太远，也许没有，但我认为这个地方（）不起作用，而且我很难找出原因。

提前致谢。

Python Tkinter Button Widget不会移动
