Question

我正在尝试使用tkinter按钮。我想在我的时钟脚本中插入一些按钮。

插入按钮退出（从底部第3行）插入按钮确定，按钮有效，但它拒绝在按钮上显示任何文字。

如何在此按钮上显示文字？

import sys
if sys.version_info[0] == 2:
    from Tkinter import *
    import Tkinter as tk
else:
    from tkinter import *
    import tkinter as tk

from time import *


fontsize=75
fontname="Comic Sans MS"        #font name - use Fontlist script for names
fontweight="bold"       #"bold" for bold, "normal" for normal 
fontslant="roman"       #"roman" for normal, "italic" for italics

def quit():
    clock.destroy()

def getTime():
    day = strftime("%A")
    date = strftime("%d %B %Y")
    time = strftime("%I:%M:%S %p")
    text.delete('1.0', END)                 #delete everything
    text.insert(INSERT, '\n','mid')
    text.insert(INSERT, day + '\n', 'mid')        #insert new time and new line
    text.insert(INSERT, date + '\n', 'mid')
    text.insert(INSERT, time + '\n', 'mid')
    clock.after(900, getTime)               #wait 0.5 sec and go again


clock = tk.Tk() # make it cover the entire screen
w= clock.winfo_screenwidth()
h= clock.winfo_screenheight()
clock.overrideredirect(1)
clock.geometry("%dx%d+0+0" % (w, h))
clock.focus_set() # <-- move focus to this widget
clock.bind("<Escape>", lambda e: e.widget.quit())
text = Text(clock, font=(fontname, fontsize, fontweight, fontslant))
text.grid(column = 1, columnspan = 1, row = 2, rowspan = 1, sticky='')           

Exit = Button(clock, text="Close Tkinter Window", width = w, height = 1, command=quit).grid(row = 1, rowspan = 1, column = 1, columnspan = w)

clock.after(900, getTime)
clock.mainloop()

Answer 1

排序解决了它。按钮显示文本 - 它刚刚离开屏幕。通过调整tkinter文本窗口和按钮的宽度来解决它。

Answer 2

w（clock.winfo_screenwidth()）的值对于按钮宽度而言太宽。它只是将按钮的名称滑动到左侧太多。因此，将按钮的宽度更改为较小的数字（200），并将sticky=W添加到grid，这样它就不会再滑动太多了。同时，按钮的宽度将覆盖父窗口的整个宽度（如您所愿）。所以这是替换的内容：

Exit = Button(clock, text="Close Tkinter Window", width = 200, height = 1, command=quit).grid(row = 1, rowspan = 1, column = 1, columnspan = w, sticky=W)

Answer 3

Tkinter中Button的基本结构是

button1=Button(root,text="This is text ",command=functionname)
button1.pack()

Python Tkinter按钮 - 没有文字
