问题描述
我正在尝试在具有列的 Tkinter 中创建一个 Listbox
.
I'm trying to create a Listbox
in Tkinter that has columns.
我从数据库查询记录返回,并希望为每条记录在其自己的列中显示每个条目.
I'm returning from a DB query records and would like to display each entry in it's own column for each record.
看Listbox
,感觉应该有这个功能,但是找不到.我应该使用什么小部件来做到这一点?我一直在网上搜索,但文档非常少.
Looking at Listbox
, I feel like there should be this functionality there but can't find it. What widget should I be using to do this? I've been searching around online but documentation has been very sparse.
推荐答案
使用 TkTreectrl:
import Tkinter as tk
import TkTreectrl as treectrl
import sqlite3
def setup_table(connection):
cursor=connection.cursor()
cursor.execute('''CREATE TABLE foo
(id INTEGER PRIMARY KEY AUTOINCREMENT,
bar TEXT)''')
sql='INSERT INTO foo (bar) values (?)'
for i in range(10):
cursor.execute(sql,(i,))
cursor.execute(sql,(u'N{INFINITY}',))
def select_cmd(selected):
print 'Selected items:', selected
def main():
connection=sqlite3.connect(':memory:')
setup_table(connection)
cursor=connection.cursor()
root = tk.Tk()
root.title('Simple MultiListbox demo')
mlb = treectrl.MultiListbox(root)
mlb.pack(side='top', fill='both', expand=1)
tk.Button(root, text='Close', command=root.quit).pack(side='top', pady=5)
mlb.focus_set()
mlb.configure(selectcmd=select_cmd, selectmode='extended')
mlb.config(columns=('Column 1', 'Column 2'))
cursor.execute('SELECT * from foo')
for row in cursor.fetchall():
mlb.insert('end',*map(unicode,row))
root.mainloop()
if __name__=='__main__':
main()
