编辑列表框中的对象及其来源列表

Question

我开始制作一个功能，当双击列表框中的选择时，会返回选择信息（字典）。

def OnDouble(self, event):
        widget = event.widget
        selection = widget.curselection()
        value = widget.get(selection[0])

我想要的是能够获取返回的选择并编辑其内容。通过这样做，内容的任何更改都应该显示在列表框和它来自的列表中。

双击返回的值示例：

{'Num Tel/Cel': 'test1', 'Email': 'test1', 'Fecha de Entrega': '', 'Orden Creada:': ' Tuesday, June 23, 2015', 'Nombre': 'test1', 'Num Orden': '1'}

Answer 1

您可以使用此 documentation 中给出的函数来编辑列表框的选择。

例子-

widget.selection_set(<item to add>) # adds an item to the selection

或

widget.selection_clear(<item to remove>) # removes the item from the selection

selection_set 的文档 - here selection_clear - here

from Tkinter import *

oneThing = {"Name:": "Guido", "Tel.:":"666-6969", "Email:":"foobar@lol.com"}
another = {"Name:": "Philler", "Tel.:":"111-1111", "Email:":"philler@lol.com"}
z = [oneThing, another]

root = Tk()
l = Listbox(root)
l.pack(fill = "both")
l.pack_propagate(True)
[l.insert(END, item) for item in z]

def createPerson(index):

    #This is whatever function that creates stuff

    def edit():

        for i in range(len(labels)):
            z[index][labels[i]] = entries[i].get()
        print z
        top.destroy()

    top = Toplevel()
    labels = ["Name:", "Tel.:", "Email:"]
    i = 0
    for text in labels:
        Label(top, text = text).grid(column = 0, row = i)
        i += 1

    e1 = Entry(top)
    e1.grid(column = 1, row = 0)
    e2 = Entry(top)
    e2.grid(column = 1, row = 1)
    e3 = Entry(top)
    e3.grid(column = 1, row = 2)
    Button(top, text = "Submit", command = edit).grid(column = 1, row = 3)
    entries = [e1, e2, e3]

    #Return reference to toplevel so that root can wait for it to run its course
    return top

def edit():
    global l, z, root
    # Get dictionary from listbox
    sel = l.curselection()
    if len(sel) > 0:
        indexToEdit = z.index(eval(l.get(sel[0])))
        l.delete(sel)
        root.wait_window(createPerson(indexToEdit))
        print z[indexToEdit]
        l.insert(sel, z[indexToEdit])

Button(root, text = "Edit", command = edit).pack()
root.mainloop()

Edit：示例现在展示了一种根据用户输入动态编辑元素的方法；使用 Toplevel() 小部件接受输入。
