Question

我有一个在主窗口中打开的画布，但是我希望它在Frame内部的画布中打开。我试图添加一些疯狂的属性（因为它们在我的手中），但是它们并不能解决我的问题，因此我删除了它们，不知道该怎么办。您能帮我吗-我怎么能知道呢？

代码：

from tkinter import *
from tkinter import ttk


class Example(Frame): # Frame
 def __init__(self, root):
    Frame.__init__(self, root)

    # ---- for grid ----
    canvas_width = 1000  # MUTABLE!!!
    canvas_height = 1000  # MUTABLE!!!
    self.canvas_width = canvas_width
    self.canvas_height = canvas_height

    self.warehouse_canvas = Canvas(self, width=canvas_width, height=canvas_height, background="bisque")
    self.x_scrollbar = Scrollbar(self, orient="horizontal", command=self.warehouse_canvas.xview)
    self.y_scrollbar = Scrollbar(self, orient="vertical", command=self.warehouse_canvas.yview)
    self.warehouse_canvas.configure(yscrollcommand=self.y_scrollbar.set, xscrollcommand=self.x_scrollbar.set)
    self.warehouse_canvas.configure(scrollregion=(0, 0, canvas_width, canvas_height)) # c_w c_h изменены

    self.x_scrollbar.grid(row=1, column=0, sticky="ew")
    self.y_scrollbar.grid(row=0, column=1, sticky="ns")
    self.warehouse_canvas.grid(row=0, column=0, sticky="nsew")
    self.grid_rowconfigure(0, weight=1)
    self.grid_columnconfigure(0, weight=1)


    root.columnconfigure(1, weight=1)
    root.rowconfigure(1, weight=1)


    self.warehouse_canvas.bind("<ButtonPress-1>", self.scroll_start)
    self.warehouse_canvas.bind("<B1-Motion>", self.scroll_move)


    self.draw_grid(self.warehouse_canvas, canvas_width, canvas_height) # !!!

def draw_grid(root, warehouse_canvas, canvas_width, canvas_height):
    for line in range(0, canvas_width, 10):
        warehouse_canvas.create_line([(line, 0), (line, canvas_height)], fill='#d9d9d9', tags='grid_line_width')
    for line in range(0, canvas_width, 10):
        warehouse_canvas.create_line([(0, line), (canvas_width, line)], fill='#d9d9d9', tags='grid_line_height')
    # warehouse_canvas.grid(row=0, column=0)               color :  #d9d9d9

def scroll_start(self, event):
    self.warehouse_canvas.scan_mark(event.x, event.y)

def scroll_move(self, event):
    self.warehouse_canvas.scan_dragto(event.x, event.y, gain=1)



if __name__ == "__main__":
   root = Tk()

   Example(root).grid(row=0, column=0, # положение
                   columnspan=2, rowspan=2, sticky="nsew")

   root.mainloop()

What I have

Where I want it to be

有什么方法可以不用重写整个代码吗？
