[英]How to initialise the calendar with blank date in tkcalendar?
I'm trying to create a date picker.我正在尝试创建一个日期选择器。 I found a code online that works for me.
我在网上找到了一个对我有用的代码。 However, with this code, the program shows today's date as default when it starts like this:
但是,使用此代码,程序在启动时默认显示今天的日期,如下所示:
Is there a way to set the default date to blank like this?有没有办法像这样将默认日期设置为空白?
I have been looking for an answer but no luck.我一直在寻找答案,但没有运气。
import tkinter as tk
from tkinter import ttk
from tkcalendar import DateEntry
from datetime import date
root = tk.Tk()
style = ttk.Style(root)
style.theme_use('clam')
class MyDateEntry(DateEntry):
def __init__(self, master=None, **kw):
DateEntry.__init__(self, master=None, **kw)
self._top_cal.configure(bg='black', bd=1)
de = MyDateEntry(root,selectbackground='gray80',
selectforeground='black',
normalbackground='white',
normalforeground='black',
background='gray90',
foreground='black',
bordercolor='gray90',
othermonthforeground='gray50',
othermonthbackground='white',
othermonthweforeground='gray50',
othermonthwebackground='white',
weekendbackground='white',
weekendforeground='black',
headersbackground='white',
headersforeground='gray70')
de.pack()
root.mainloop()
DateEntry
is inherited from Entry
widget. DateEntry
继承自Entry
小部件。 So you can delete the content just like a normal Entry
widget:因此,您可以像普通
Entry
小部件一样删除内容:
class MyDateEntry(DateEntry):
def __init__(self, master=None, **kw):
DateEntry.__init__(self, master=None, **kw)
self._top_cal.configure(bg='black', bd=1)
self.delete(0, "end")
I did not need to make a class.我不需要上课。 This solution works totally fine:
此解决方案完全正常:
date_started = DateEntry(root, locale='en_US', date_pattern='yyyy-mm-dd')
date_started.delete(0, "end") ## Only this line needed to be added to clear the field.
date_started.place(x=150, y=60, height=25, width=120)
