Hi everyone,
I've found this code to enter the date and that I'd like to use in tkinter but I'm having several issue:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 |
import tkinter as tk
from datetime import datetime
class DateEntry(tk.Frame):
def __init__(self, parent, **kwargs):
years = kwargs.pop('years', (1900, 9999))
super().__init__(parent, **kwargs)
vcmd = (self.register(self._validate), '%W', '%V', '%v', '%P', '%S')
for name, text, v1, v2 in (('day', 'DD', 1, 31),
('month', 'MM', 1, 12),
('year', 'YYYY', years[0], years[1])):
e = tk.Entry(self, name=name, width=len(text) + 2, justify="center")
e.pack(side=tk.LEFT)
e.insert(0, text)
e._valid = (len(text), v1, v2)
e.config(validate="all", validatecommand=vcmd)
def get(self):
data = {}
for entry in [self.nametowidget(child) for child in self.children]:
text = entry.get()
data[entry.winfo_name()] = int(text) if text.isdigit() else None
return data
def _validate(self, widget, cmd, validate, value, text):
w = self.nametowidget(widget)
if cmd in ('focusin', 'forced') or value == '':
if not value.isdigit():
w.delete(0, tk.END)
w.after_idle(w.config, {'validate': validate})
return True
elif cmd == 'key' and value.isdigit():
l, v1, v2 = w._valid
if v1 > 1 and len(value) < l:
l2 = len(value)
v1, v2 = int(str(v1)[:l2]), int(str(v2)[:l2])
elif v1 == 1 and len(value) == 1 and int(value) == 0:
return True
return all((text.isdigit(), v1 <= int(value) <= v2, len(value) <= l))
return False
|
This is how I'm using it after importing it
1 2 3 4 |
self.birthday = StringVar(self)
self.birthday.set('')
self.birthday=DateEntry(self, years=(1935, 2020))
self.birthday.place(relx=0.22, rely=0.16, height=25, width=100)
|
I cannot access to the entry input I'm trying this way:
1 2 3 4 5 |
for key in self.birthday.keys():
birth_year = self.birthday.get('year')
birth_month = self.birthday.get('month')
birth_day = self.birthday.get('day')
birth_date = datetime.datetime(birth_year, birth_month, birth_day)
|
But it gives me this error "birth_year = self.birthday.get('year')
TypeError: get() takes 1 positional argument but 2 were given". I've no idea why this is happening.
Also I'd like to edit a little the code and I was wondering if it could be possible to:
1. Po put a little bit of space between the three boxes and add a "/" between them?
2. Also right now it is possible to input incorrect date like 31 November ecc. How could I fix this?
Thank you all for your help!

have you seen the tkcalendar widget? found hereThe benefit is it uses the calendar so you get leap years, super easy to use:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 |
>>> from tkcalendar import Calendar, DateEntry
>>> from tkinter import Tk
>>> root= Tk()
>>> date_entry= DateEntry(root)
>>> date_entry.pack()
>>> now= date_entry.get()
>>> now
'4/19/20'
>>> mo_dy_yr= now.split('/')
>>> mo= now[0]
>>> mo
'4'
>>> dy= mo_dy_yr[1]
>>> dy
'19'
>>> yr= mo_dy_yr[2]
>>> yr
'20'
|
but if you're going to create a new one-
Quote:self.birthday = StringVar(self)
self.birthday.set('')
self.birthday=DateEntry(self, years=(1935, 2020))
self.birthday.place(relx=0.22, rely=0.16, height=25, width=100)
first to create a string var and set it none then you over right the namespace and make it a dateentry widget. if you want the information you need .get()
at the bottom of your script I included a test:
1 2 3 4 5 6 7 8 9 |
if __name__ =='__main__':
root= tk.Tk()
d=DateEntry(root,years=('2000','2020'))
d.pack()
def get_entry():
txt=d.get()
print(txt)
btn= tk.Button(root,text='hello',command= get_entry)
btn.pack()
|
I did get an error when I tried to enter 1 in the year:
Quote:File "/home/pi/misc/yk_homeade_datepicker.py", line 46, in _validate
if v1 > 1 and len(value) < l:
TypeError: '>' not supported between instances of 'str' and 'int'

if v1 > 1 and len(value) < l:
TypeError: '>' not supported between instances of 'str' and 'int' I did saw the calendar script which is really beautiful, but I'm afraid it might need a lot of time and increment the chance of error input if used for birthday.
For what I've understand the script I'm trying to use gives back a dict and I don't know how to access it since it usually gives me back the "TypeError: get() takes 1 positional argument but 2 were given" error and I don't know why.

In my test I used root which is TK as the master you're using self
Quote:self.birthday=DateEntry(self, years=(1935, 2020))
I changed line 48 to len(v1) threw errors on the day and month

When I use the def get_entry() it gives me back "none" as result, I manage to solve the "TypeError: get() takes 1 positional argument but 2 were given" error but it gives me back "0". It seems I can't get the user input date with get(). Is there a way to solve this? After my users enter their birthday I want to be able to use .get() or any other way to save the info. How could I do so? Thank you!

After I import it, and run it I get an error type in the year and this output
Quote:{'day': 10, 'month': 11, 'year': 2001}
this larz's hoover example with your date entry, modify the import- it's an example only
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 |

I've tried datetime.strptime to convert the date but with no luck.
