Tkinter:在画布内制作一个画布宽度的框架

Question

我在画布中使用了一个框架，这样我就可以在使用网格布局的同时添加滚动条。我之所以使用网格布局，是因为显示的信息(结果(并不都是相同的宽度，但我希望列具有相同的维度。

但是，我希望框架(蓝色(通过在列之间均匀划分所有空间来占用画布(黄色(的所有空间：此处为图像

这是我上面图片的代码：

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()

有人知道怎么修吗？如果是，请告诉我。(使用python 3(

您需要将宽度规范添加到标签实例化中，然后在column-configure语句中进行填充，以扩展列以适应可用空间。

宽度规格可确保所有标签的大小相同。

代码：将tkinter导入为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()
