Python 3.x 从sqlite检索图像并添加到listbox tkinter python

我试图从我的数据库中获取一个blob图像并将其插入列表框，但我做不到。 有什么办法吗

我的全部代码：

from tkinter import *
from tkinter import messagebox, Tk, Label, filedialog, font
from blobdb import Database

    cursor = sqliteConnection.cursor()
    print("Connected to SQLite")
    sqlite_select_query = """SELECT * from contacts"""
    cursor.execute(sqlite_select_query)
    records = cursor.fetchall()
    for row in records:
        listBox.insert (END, (row[1], row[2]))


def convertToBinaryData(filename):
    # Convert digital data to binary format
    with open(filename, 'rb') as file:
        blobData = file.read()
    return blobData


def insertBLOB(id, name, last_name, photo, phone_num, email, home_address):
    print(id, name, last_name, photo, phone_num, email)
    try:
        sqliteConnection = sqlite3.connect('store.db')
        cursor = sqliteConnection.cursor()
        print("Connected to SQLite")
        sqlite_insert_blob_query = """ INSERT INTO contacts (id, name, last_name, photo, phone_num, email, home_address) VALUES (?, ?, ?, ?, ?, ?, ?)"""

        empPhoto = convertToBinaryData(photo)
        # Convert data into tuple format
        data_tuple = (id, name, last_name, empPhoto,
                      phone_num, email, home_address)
        cursor.execute(sqlite_insert_blob_query, data_tuple)
        sqliteConnection.commit()
        listBox.delete (0, END)
        fetch_contact()

        print("Image and file inserted successfully as a BLOB into a table")
        cursor.close()

    except sqlite3.Error as error:
        print("Failed to insert blob data into sqlite table", error)

无法将图像插入

列表框

。但是您可以使用

Text.image\u create（）

将图像插入

Text

。然后我可以将其插入列表框吗？不，只能将字符串插入

Listbox

。那么如何将列表框行合并到图像并显示图像？您需要创建一个可滚动的框架，并将图像放在这个框架中，以便可以滚动。请参见，您无法将图像插入
