Tkinter：在 canvas 內部制作一個框架 canvas 的寬度

Question

我在 canvas 中使用了一個框架，因此我可以在使用網格布局時添加滾動條。 我正在使用網格布局，因為顯示的信息（結果）的寬度並不完全相同，但我希望列具有相同的尺寸。

但是，我希望框架（藍色）通過在列之間均勻划分所有空間來占據 canvas（黃色）的所有空間：圖像在這里

這是我上面顯示的圖片的代碼：

import tkinter as tk

class SeeTransactions():

    def showInterface(self):

        self.frameCanvas = tk.Frame(window)
        self.frameCanvas.grid(row=0, column=0, pady=(5, 0), sticky='news')
        self.frameCanvas.grid_rowconfigure(0, weight=1)
        self.frameCanvas.grid_columnconfigure(0, weight=1)
        self.frameCanvas.grid_propagate(False)

        self.canvas = tk.Canvas(self.frameCanvas, bg = 'yellow')
        self.canvas.grid(row=0, column=0, sticky="news")

        self.frameDatabase = tk.Frame(self.canvas, bg = 'blue')
        self.frameDatabase.grid(row = 0, column = 0, sticky = 'news')

        self.canvas.create_window((0, 0), window=self.frameDatabase, anchor='nw')

        self.vsb = tk.Scrollbar(self.frameCanvas, orient="vertical", command=self.canvas.yview)
        self.vsb.grid(row=0, column=1, sticky='ns')
        self.canvas.configure(yscrollcommand=self.vsb.set)

        self.showDatabase()


    def showDatabase(self):

        result = >some list

        for row in range(len(result)):

            for column in range(1, 5):

                tk.Label(self.frameDatabase, text = result[row][column]).grid(row = row, column = column - 1)

                self.frameDatabase.columnconfigure(column, weight = 1, uniform = 'all')

            tk.Label(self.frameDatabase, text = result[row][5]).grid(row = row, column = 4, columnspan = 2, sticky = 'w')

        self.frameDatabase.columnconfigure(4, weight = 1, uniform = 'all')

        self.frameDatabase.update_idletasks()

        self.frameCanvas.config(width=891, height=400)

        self.canvas.config(scrollregion=self.canvas.bbox("all"))



window = tk.Tk()
window.title('MyBudget')
window.geometry('891x531')

seeTransactions = SeeTransactions()

seeTransactions.showInterface()

window.mainloop()

有誰知道如何修理它？ 如果是這樣，請告訴我。 （使用 python 3）

您需要將寬度規范添加到 label 實例化，並在列配置語句中進行填充以擴展列以適應可用空間。

寬度規格確保所有標簽的大小相同。

代碼：導入 tkinter 作為 tk

class SeeTransactions():

    def showInterface(self):

        self.frameCanvas = tk.Frame(window)
        self.frameCanvas.grid(row=0, column=0, pady=(5, 0), sticky='news')
        self.frameCanvas.grid_rowconfigure(0, weight=1)
        self.frameCanvas.grid_columnconfigure(0, weight=1)
        self.frameCanvas.grid_propagate(False)

        self.canvas = tk.Canvas(self.frameCanvas, bg = 'yellow')
        self.canvas.grid(row=0, column=0, sticky="news")

        self.frameDatabase = tk.Frame(self.canvas, bg = 'blue')
        self.frameDatabase.grid(row = 0, column = 0, sticky = 'news')

        self.canvas.create_window((0, 0), window=self.frameDatabase, anchor='nw')

        self.vsb = tk.Scrollbar(self.frameCanvas, orient="vertical",     command=self.canvas.yview)
        self.vsb.grid(row=0, column=1, sticky='ns')
        self.canvas.configure(yscrollcommand=self.vsb.set)
        self.showDatabase()

def showDatabase(self):
    result = [[f'line{i}{j}' for i in range(10)] for j in range(20)]
    for row in range(len(result)):
        for column in range(1, 5):
            tk.Label(self.frameDatabase, text = result[row][column], width = 15).grid(row = row, column = column - 1)

            self.frameDatabase.columnconfigure(column, weight = 1, uniform = 'all',pad = 100)

        tk.Label(self.frameDatabase, text = result[row][5], width = 15).grid(row = row, column = 4, columnspan = 2, sticky = 'w')

    self.frameDatabase.columnconfigure(4, weight = 1, uniform = 'all',pad = 100)

    self.frameDatabase.update_idletasks()

    self.frameCanvas.config(width=891, height=400)

    self.canvas.config(scrollregion=self.canvas.bbox("all"))



window = tk.Tk()
window.title('MyBudget')
window.geometry('891x531')

seeTransactions = SeeTransactions()

seeTransactions.showInterface()
