使用Tkinter获取在列表框中选择的多个项目并使用值填充新列表 [英] get multiple items chosen in a listbox and populate new list with the values, using Tkinter

问题描述

我正在尝试从列表框中进行选择，并用它填充一个新列表，它将是多个项目.我无法弄清楚，这是到目前为止的内容(我需要列表中的实际字符串，而不是索引).另外，选择后如何完全摆脱Tkinter小部件-它已关闭，但关闭后似乎仍然有鬼影.

I am trying to take the selection from a listbox and populate a new list with it, and it will be multiple items. I can't figure this out, here's what i have so far (and I need the actual strings in the list, not the indices). Also, how can I completely get rid of the Tkinter widgets after making the selection - it closes out but it seems like there is a ghost of it still hanging around after it closes.

def execute(*events):
   UsrFCList = []
   selctd_indices = lbox.curselection()
   lst_select = list(selctd_indices)
   for i in lst_select:
      lbox.get(i)
      UsrFCList.append(i)
   lbox.quit()

fc_lb = Tk()
scrollbar = Scrollbar(fc_lb)
scrollbar.pack(side=RIGHT, fill=Y)
lbox = AutoSzLB(fc_lb,selectmode=EXTENDED)
for item in lb_list:
  lbox.insert(END, *item)

button = Button(fc_lb, text="Analyze selected feature classes", command=execute)

lbox.autowidth(250)
lbox.pack()
button.pack()

lbox.config(yscrollcommand=scrollbar.set)
scrollbar.config(command=lbox.yview)

mainloop()

推荐答案

我知道了，而不是

for i in lst_select:
  lbox.get(i)
  UsrFCList.append(i)

是

for i in lst_select:
    UsrFCList.append(lbox.get(i))
