在 Tkinter 中创建表

Question

我想在 MySQL 中使用 select 语句显示所有满足特定条件的数据，并在 Tkinter 界面上以表格的形式连同字段名称一起显示。我的 sql 表包含字段 DATE_OF_PROCUREMENT(date)， PART_NO(varchar),COMPONENT_NAME(varchar),QUANTITY(big int),COST_PER_UNIT(float),TOTAL_COST(fl​​oat)。谁能帮忙？我试过这个：

import tkinter as tk
from tkinter import ttk
from tkinter import *
from tkcalendar import Calendar, DateEntry

import MySQLdb as mydb
import datetime
import tkinter.messagebox
root=tk.Tk()
tabcontrol=ttk.Notebook(root)
tab1=ttk.Frame(tabcontrol)
tab2=ttk.Frame(tabcontrol)
tabcontrol.add(tab1,text="Entry Form")
tabcontrol.pack(expand=1,fill='both')
tabcontrol.add(tab2,text="Report")
tabcontrol.pack(expand=1,fill='both')
conn=mydb.connect(host='localhost',user='root',passwd='root',database='operator')
mycur=conn.cursor()
mycur.execute("USE OPERATOR")

def savedata():
    etext2=tk.Entry(tab1,textvariable=partno)
    etext3=tk.Entry(tab1,textvariable=cname)
    etext4=tk.Entry(tab1,textvariable=quantity)
    etext5=tk.Entry(tab1,textvariable=cpu)
    etext_2=etext2.get()
    etext_3=etext3.get()
    etext_4=etext4.get()
    etext_5=etext5.get()
    cal = DateEntry(width=12, background='darkblue',
                foreground='white', borderwidth=2)
    dt=cal.get_date()
    dt1=datetime.datetime.strftime(dt,'%Y-%m-%d')
    etext_6=int(etext_4)*float(etext_5)
    if float(etext_5) < 1000:
        s="INSERT INTO PROCUREMENT_FORM (DATE_OF_PROCUREMENT,PART_NO,COMPONENT_NAME,QUANTITY,COST_PER_UNIT,TOTAL_COST) VALUES (%s,%s,%s,%s,%s,%s)"
        ss=(dt1,etext_2,etext_3,etext_4,etext_5,etext_6)


mycur.execute(s,ss)

conn.commit()

def dateentry_view():

def onClick(event=None):
    quantity.set(quantity.get() + 1)

Answer 1

使用grid(row=..., column=...) 代替place() 可以创建表。 enumerate() 也可用于获取 (row=..., column=...) 的值 (x,y)

import tkinter as tk

# data from database

data = [
    ['A', 'B', 'C'],
    ['X', 'Y', 'Z'],
    [12345, 67890, 99999],
]

# --- main ---

root = tk.Tk()

for y, row in enumerate(data):
    for x, item in enumerate(row):
        l = tk.Label(root, text=str(item))
        l.grid(row=y, column=x)

root.mainloop()

如果你也把它放在黑色背景的Frame 中，并在网格中使用填充，那么你可以得到

import tkinter as tk

# data from database

data = [
    ['A', 'B', 'C'],
    ['X', 'Y', 'Z'],
    [12345, 67890, 99999],
]

# --- main ---

root = tk.Tk()

frame = tk.Frame(root, bg='black')
frame.pack()

for y, row in enumerate(data):
    for x, item in enumerate(row):
        l = tk.Label(frame, text=str(item))
        l.grid(row=y, column=x, padx=1, pady=1, sticky='news')

root.mainloop()

但这在您只想显示数据时很有用。如果要突出显示行，按列排序，编辑则更好的是TreeView
