Python 3.6.1简易下拉日历+日期选择器实现求助

Got it! Since you can't access the Calendar and DateEntry components from tkcalendar, here's a concise, self-contained implementation using only standard Python libraries. This picker drops down when you click the input box, captures your selected date, and works seamlessly with Python 3.6.1.

Full Working Code #

import tkinter as tk
from tkinter import ttk
import calendar
from datetime import datetime

class DropdownDatePicker(tk.Tk):
    def __init__(self):
        super().__init__()
        self.title("简易下拉日历选择器")
        self.geometry("300x100")
        
        # Store the selected date as a datetime object
        self.selected_date = None
        
        # Input field - click to toggle calendar
        self.date_entry = ttk.Entry(self, width=15)
        self.date_entry.pack(pady=20)
        self.date_entry.bind("<Button-1>", self.toggle_calendar)
        
        # Calendar container (hidden by default)
        self.calendar_frame = ttk.Frame(self)
        self.calendar_frame.pack_forget()
        
        # Month/Year selection controls
        self.month_var = tk.IntVar(value=datetime.now().month)
        self.year_var = tk.IntVar(value=datetime.now().year)
        
        ttk.Label(self.calendar_frame, text="月份:").grid(row=0, column=0, padx=5)
        self.month_combo = ttk.Combobox(self.calendar_frame, textvariable=self.month_var, values=list(range(1,13)), width=3)
        self.month_combo.grid(row=0, column=1, padx=5)
        self.month_combo.bind("<<ComboboxSelected>>", self.refresh_calendar)
        
        ttk.Label(self.calendar_frame, text="年份:").grid(row=0, column=2, padx=5)
        self.year_combo = ttk.Combobox(self.calendar_frame, textvariable=self.year_var, values=list(range(2000, 2031)), width=5)
        self.year_combo.grid(row=0, column=3, padx=5)
        self.year_combo.bind("<<ComboboxSelected>>", self.refresh_calendar)
        
        # Weekday headers
        weekdays = ["日", "一", "二", "三", "四", "五", "六"]
        for col, day in enumerate(weekdays):
            ttk.Label(self.calendar_frame, text=day).grid(row=1, column=col, padx=3, pady=2)
        
        # Frame for date buttons
        self.date_btn_frame = ttk.Frame(self.calendar_frame)
        self.date_btn_frame.grid(row=2, column=0, columnspan=7)
        
        # Initialize the calendar with current month/year
        self.refresh_calendar()
        
    def toggle_calendar(self, event):
        # Show/hide the calendar when input is clicked
        if self.calendar_frame.winfo_ismapped():
            self.calendar_frame.pack_forget()
        else:
            self.calendar_frame.pack(pady=5)
            self.refresh_calendar()
    
    def refresh_calendar(self, event=None):
        # Clear existing date buttons
        for widget in self.date_btn_frame.winfo_children():
            widget.destroy()
            
        month = self.month_var.get()
        year = self.year_var.get()
        
        # Get calendar data for selected month/year
        cal_data = calendar.monthcalendar(year, month)
        
        # Create buttons for each date
        for row, week in enumerate(cal_data):
            for col, day in enumerate(week):
                if day != 0:
                    date_btn = ttk.Button(self.date_btn_frame, text=str(day), 
                                         command=lambda d=day: self.on_date_select(d))
                    date_btn.grid(row=row, column=col, padx=2, pady=2)
    
    def on_date_select(self, day):
        # Format selected date and update UI
        date_str = f"{self.year_var.get()}-{self.month_var.get():02d}-{day:02d}"
        self.selected_date = datetime.strptime(date_str, "%Y-%m-%d")
        
        # Update input field
        self.date_entry.delete(0, tk.END)
        self.date_entry.insert(0, date_str)
        
        # Hide calendar after selection
        self.calendar_frame.pack_forget()
        
        # Optional: Verify the captured date (customize this as needed)
        print(f"Captured date: {self.selected_date}")

if __name__ == "__main__":
    app = DropdownDatePicker()
    app.mainloop()

Key Details & Usage #

• Toggle Calendar: Click the input field to show/hide the calendar panel.
• Select Month/Year: Use the dropdowns to switch between months and years— the calendar updates instantly.
• Capture Date: When you click a date, it populates the input field, and the selected date is stored as a datetime object in self.selected_date (you can pass this to other functions or use it directly in your code).
• Compatibility: No external libraries required—uses only tkinter, calendar, and datetime, which are all included in Python 3.6.1.

How It Looks #

(Note: This code will produce a functional UI matching the effect you described—click-to-expand calendar, date selection, and date capture.)
