Question

尝试使用我的元组中的spaecific记录填充tkinter combobox 然后，当我选择组合框中的记录打印我想得到的相应的记录未在组合框中填充。

它填充了combobox 1 ben journalism 18之类的内容。但是我希望像ben那样将其打包出来，然后当我选择它时会像1 ben journalism 18那样打印。

from tkinter import *
from tkinter import ttk



rows = ((1, 'ben', 'journalism', 18), (2, 'sally', 'performing arts', 22),(3,"dan","information technology",32))


def selected(event=None):
    print(cb.get()) # print selected record in other column


root = Tk()

cb = ttk.Combobox(root)
cache = list()
for row in rows:
    cache.append(row)
    cb['values'] = cache

cb.pack()
cb.bind("<<ComboboxSelected>>", selected)

root.mainloop()

Answer 1

一些小的改动应该为你解决。首先，我假设行是列表，如[[1，'ben'，'新闻'，18]，[2，'sally'，'表演艺术'，22] ...]

def selected(event=None):
    # Find the row that contains the selected student's name
    for row in rows:
        if cb.get() in row:
            # Found it. Print it.
            print(row)
            break

for row in rows:
    # Insert just the student name into combobox
    cache.append(row[1])
cb['values'] = cache
