Question

我有一个框架，位于row = 0，其中包含High和Low中我想要的文字column = 2和column = 3 ##Forecast Frame self.ForecastFrame = Frame(self, bg='black') self.ForecastFrame.grid(row = 0, column = 0) ##Forecast Title self.forecastTitle = Frame(self.ForecastFrame, bg='white') self.forecastTitle.grid(row = 0, column = 0, sticky = E) self.forecastTitleHighLabel = Label(self.forecastTitle, text='High', font=('HelveticaNeue Light', 12), fg='white', bg='green', width = '7', anchor='center') self.forecastTitleHighLabel.grid(row = 0, column = 2, sticky = E) self.forecastTitleLowLabel = Label(self.forecastTitle, text='Low', font=('HelveticaNeue Light', 12), fg='white', bg='blue', width = '7', anchor='center') self.forecastTitleLowLabel.grid(row = 0, column = 3, sticky = E) ##Forecast One Labels self.forecastOneDate = '' self.forecastOneIcon = '' self.forecastOneHigh = '' self.forecastOneLow = '' self.forecastOne = Frame(self.ForecastFrame, bg='black') self.forecastOne.grid(row = 1, column = 0) self.forecastOneDateLabel = Label(self.forecastOne, font=('HelveticaNeue Light', 12), fg='white', bg='yellow', width=10, anchor='w') self.forecastOneDateLabel.grid(row = 0, column = 0, sticky = W) self.forecastOneIconLabel = Label(self.forecastOne, bg='red', width=50) self.forecastOneIconLabel.grid(row = 0, column = 1, sticky = W) self.forecastOneHighLabel = Label(self.forecastOne, font=('HelveticaNeue Light', 12, 'bold'), fg='white', bg='blue', width = '7', anchor='center') self.forecastOneHighLabel.grid(row = 0, column = 2, sticky = E) self.forecastOneLowLabel = Label(self.forecastOne, font=('HelveticaNeue Light', 12, 'bold'), fg='white', bg='green', width = '7', anchor='center') self.forecastOneLowLabel.grid(row = 0, column = 3, sticky = E)。我下面有另一行包含数值。但是在标签上我将宽度设置为全等于7.

我在这里做错了什么？

effbot.org：Label

width =

标签的宽度。如果标签显示文字，则尺寸以文本单位给出。如果标签显示图像，则尺寸以像素（或屏幕单位）给出。如果大小设置为0或省略，则根据标签内容计算。（宽度/宽度）

这意味着width取决于字体大小和重量。

import tkinter as tk root = tk.Tk() l1 = tk.Label(root, text='Hello', width=7, fg='white', bg='blue') f = ('HelveticaNeue Light', 12) l2 = tk.Label(root, text='Hello', width=7, fg='white', bg='green', font=f) f = ('HelveticaNeue Light', 12, 'bold') l3 = tk.Label(root, text='Hello', width=7, fg='white', bg='red', font=f) l1.grid() l2.grid() l3.grid() root.mainloop()

为什么即使宽度相等，我的标签也会有不同的尺寸？
