我正在尝试创建一个tkinter窗口，显示当前时间和日期，以及自定义短语。但问题在于，当天过去后无法刷新日期。
我可以传递代码运行时的当前日期，但之后就变为静态了。
以下是我的目前程序:
import tkinter as tk
import sys
import time
import calendar
import random
import datetime as dt
from tkinter import *
""" DICTIONARY PHRASES """
phrases = ["Phrase1", "Phrase2", "Phrase3"]
class Clock(tk.Label):
""" Class that contains the clock widget and clock refresh """
def __init__(self, parent=None, seconds=True, colon=False):
"""
Create and place the clock widget into the parent element
It's an ordinary Label element with two additional features.
"""
tk.Label.__init__(self, parent)
self.display_seconds = seconds
if self.display_seconds:
self.time = time.strftime('%I:%M:%S %p')
else:
self.time = time.strftime('%I:%M:%S %p').lstrip('0')
self.display_time = self.time
self.configure(text=self.display_time)
if colon:
self.blink_colon()
self.after(200, self.tick)
def tick(self):
""" Updates the display clock every 200 milliseconds """
if self.display_seconds:
new_time = time.strftime('%I:%M:%S %p')
else:
new_time = time.strftime('%I:%M:%S %p').lstrip('0')
if new_time != self.time:
self.time = new_time
self.display_time = self.time
self.config(text=self.display_time)
self.after(200, self.tick)
def blink_colon(self):
""" Blink the colon every second """
if ':' in self.display_time:
self.display_time = self.display_time.replace(':',' ')
else:
self.display_time = self.display_time.replace(' ',':',1)
self.config(text=self.display_time)
self.after(1000, self.blink_colon)
class FullScreenApp(object):
def __init__(self, master, **kwargs):
self.master=master
pad=3
self._geom='200x200+0+0'
master.geometry("{0}x{1}+0+0".format(
master.winfo_screenwidth()-pad, master.winfo_screenheight()-pad))
master.bind('<Escape>',self.toggle_geom)
def toggle_geom(self,event):
geom=self.master.winfo_geometry()
print(geom,self._geom)
self.master.geometry(self._geom)
self._geom=geom
# Root is the name of the Tkinter Window. This is important to remember.
root=tk.Tk()
# Sets background color to black
root.configure(bg="black")
# Removes the window bar at the top creating a truely fullscreen
root.wm_attributes('-fullscreen','true')
tk.Button(root, text="Quit", bg="black", fg="black", command=lambda root=root:quit(root)).pack()
# this displays the clock know as clock1
clock1 = Clock(root)
clock1.pack()
# This gives the clock format.
clock1.configure(bg='black',fg='white',font=("helvetica",125))
# Gets date from host computer.
date = dt.datetime.now()
# Takes the date and formats it.
format_date = f"{date:%a, %b %d %Y}"
# Selects a random phrase from the phrases dictionary
phrase_print = random.choice(phrases)
# Add the date to the tkinter window
w = Label(root, text=format_date, fg="white", bg="black", font=("helvetica", 40))
w.pack()
# Add the phrase to the tkinter window
e = Label(root, text=phrase_print, fg="white", bg="black", font=("helvetica", 28))
e.pack()
root.mainloop()
就像我说的那样，它显示日期但只显示一次，然后就再也不会改变。
提前感谢你的帮助。
