python - 返回 tkinter 列表框中选定值的列表

Question

我正在尝试创建一个 tkinter 列表框并将用户选择的选项打印为列表。到目前为止我已经:

from tkinter import *
from tkinter import ttk

main = Tk()
main.title('Test GUI')
main.geometry('700x500')

nb = ttk.Notebook(main)
nb.grid(row=1, column=0, columnspan=50, rowspan=49, sticky='NESW')

page1 = ttk.Frame(nb)
nb.add(page1, text='Search Terms')

p1_IncludeLanguage = Listbox(page1)
p1_IncludeLanguage.configure(selectmode=MULTIPLE, width=9, height=5)
p1_IncludeLanguage.grid(row=0, column=0)

for lang in ["English", "German", "French", "Italian", "Portuguese"]:
    p1_IncludeLanguage.insert(END, lang)

main.mainloop()

我想打印列表框中选定的选项，我尝试首先使用 p1_IncludeLanguage.curselection() 获取它们的行号，但这会导致 TclError 错误: 无效的命令名称“.!notebook.!frame.!listbox”

还有其他方法可以实现这一点吗？为什么 .curselection() 不起作用？

Answer 1

这对你来说有什么作用？我添加了一个按钮，用于获取所选项目的列表。

from tkinter import *
from tkinter import ttk

def get_selection():
    items = [languages[int(item)] for item in  p1_IncludeLanguage.curselection()]
    print(items)

main = Tk()
main.title('Test GUI')
main.geometry('700x500')

nb = ttk.Notebook(main)
nb.grid(row=1, column=0, columnspan=50, rowspan=49, sticky='NESW')

page1 = ttk.Frame(nb)
nb.add(page1, text='Search Terms')

p1_IncludeLanguage = Listbox(page1)
p1_IncludeLanguage.configure(selectmode=MULTIPLE, width=9, height=5)
p1_IncludeLanguage.grid(row=0, column=0)

btnGet = Button(page1,text="Get Selection",command=get_selection)
btnGet.grid()

languages = ["English", "German", "French", "Italian", "Portuguese"]

for lang in languages:
    p1_IncludeLanguage.insert(END, lang)



main.mainloop()
