插入滚动条时TKInter帧丢失网格布局

Question

我试图创建一个有两个框架的应用程序，但我希望其中一个比另一个更宽.我找到了一种使用网格的方法，但是当我在其中一个框架上添加一个滚动条时，它会重新调整网格，这两个框架的大小相同。

这里是没有滚动条的代码：

def __init__(self, master=None):
    ctk.set_appearance_mode('system')
    ctk.set_default_color_theme('blue')

    self.__root = ctk.CTk() if master is None else ctk.CTkToplevel(master)
    self.__root. Configure(height=1500, width=944)
    self.__root.minsize(1500, 944)

    self.__main_container = ctk.CTkFrame(self.__root)

    self.__image_frame = ctk.CTkFrame(self.__main_container)
    self.__image_frame.configure(height=800, width=1000)

    self.__image_canvas = ctk.CTkCanvas(self.__image_frame)
    self.__image_canvas.configure(confine="true", cursor="crosshair")
    self.__image_canvas.grid(column=0, row=0, sticky="nsew")
    self.__image_canvas.bind("<ButtonPress-1>", self.__start_drawing)
    self.__image_canvas.bind("<ButtonRelease-1>", self.__end_drawing)
    self.__image_canvas.bind("<B1-Motion>", self.__draw_rectangle)

    self.__image_frame.grid(column=0, padx=10, pady=20, row=0, sticky="nsew")
    self.__image_frame.grid_propagate(0)
    self.__image_frame.grid_anchor("center")
    self.__image_frame.rowconfigure(0, weight=1)
    self.__image_frame.columnconfigure(0, weight=1)

    self.__boxes_frame = ctk.CTkFrame(self.__main_container)
    self.__boxes_frame.configure(height=800, width=400)
    self.__boxes_frame.grid(column=1, padx=10, pady=20, row=0, sticky="ns")

    self.__main_container.grid(column=0, padx=20, pady=40, row=0, sticky="ns")
    self.__main_container.grid_anchor("center")
    self.__main_container.rowconfigure(0, weight=1)

    self.__root.grid_anchor("center")
    self.__root.rowconfigure(0, weight=1)

    self.mainwindow = self.__root

当我添加滚动条并搅乱网格时，这就是代码

def __init__(self, master=None):
    ctk.set_appearance_mode('system')
    ctk.set_default_color_theme('blue')

    self.__root = ctk.CTk() if master is None else ctk.CTkToplevel(master)
    self.__root. Configure(height=1500, width=944)
    self.__root.minsize(1500, 944)

    self.__main_container = ctk.CTkFrame(self.__root)

    self.__image_frame = ctk.CTkFrame(self.__main_container)
    self.__image_frame.configure(height=800, width=1000)

    self.__image_canvas = ctk.CTkCanvas(self.__image_frame)
    self.__image_canvas.configure(confine="true", cursor="crosshair")
    self.__image_canvas.grid(column=0, row=0, sticky="nsew")
    self.__image_canvas.bind("<ButtonPress-1>", self.__start_drawing)
    self.__image_canvas.bind("<ButtonRelease-1>", self.__end_drawing)
    self.__image_canvas.bind("<B1-Motion>", self.__draw_rectangle)

    #------ adding the scrollbar -----
    self.__image_frame_vertical_scrollbar = ctk.CTkScrollbar(self.__image_frame, orientation="vertical")
    self.__image_frame_vertical_scrollbar.grid(column=1, row=0, sticky="ns")
    self.__image_frame_vertical_scrollbar.configure(command=self.__image_canvas.yview)
    self.__image_canvas.configure(yscrollcommand=self.__image_frame_vertical_scrollbar.set)
    #---------------------------------

    self.__image_frame.grid(column=0, padx=10, pady=20, row=0, sticky="nsew")
    self.__image_frame.grid_propagate(0)
    self.__image_frame.grid_anchor("center")
    self.__image_frame.rowconfigure(0, weight=1)
    self.__image_frame.columnconfigure(0, weight=1)

    self.__boxes_frame = ctk.CTkFrame(self.__main_container)
    self.__boxes_frame.configure(height=800, width=400)
    self.__boxes_frame.grid(column=1, padx=10, pady=20, row=0, sticky="ns")

    self.__main_container.grid(column=0, padx=20, pady=40, row=0, sticky="ns")
    self.__main_container.grid_anchor("center")
    self.__main_container.rowconfigure(0, weight=1)

    self.__root.grid_anchor("center")
    self.__root.rowconfigure(0, weight=1)

    self.mainwindow = self.__root

把事情搞砸的网格定义有什么问题？如何将__image_frame网格设置为它，以填充__main_container，保持所需的维度？

Answer 1

显式设置画布的大小。

self.__image_canvas = ctk.CTkCanvas(self.__image_frame, width=900)
