Question

如果我创建一个wx.ListCtrl并使用mixin让我能够编辑它，我如何从更改的单元格中获取数据？到目前为止，我有以下代码。当我尝试打印它/将其保存在变量中时它是空的。

def __init__(self, parent):
    """Constructor"""
    wx.Panel.__init__(self, parent)

    rows = [("Ford", "Taurus", "1996", "Blue"),
            ("Nissan", "370Z", "2010", "Green"),
            ("Porche", "911", "2009", "Red")
            ]
    self.list_ctrl = EditableListCtrl(self, style=wx.LC_REPORT)

    self.list_ctrl.InsertColumn(0, "Make")
    self.list_ctrl.InsertColumn(1, "Model")
    self.list_ctrl.InsertColumn(2, "Year")
    self.list_ctrl.InsertColumn(3, "Color")

    index = 0
    for row in rows:
        self.list_ctrl.InsertStringItem(index, row[0])
        self.list_ctrl.SetItem(index, 1, row[1])
        self.list_ctrl.SetItem(index, 2, row[2])
        self.list_ctrl.SetItem(index, 3, row[3])
        index += 1
    self.list_ctrl.Bind(wx.EVT_LIST_END_LABEL_EDIT, self.OnUpdate)
    sizer = wx.BoxSizer(wx.VERTICAL)
    sizer.Add(self.list_ctrl, 0, wx.ALL|wx.EXPAND, 5)
    self.SetSizer(sizer)

def OnUpdate(self, event):
    row_id = event.GetIndex() #Get the current row
    col_id = event.GetColumn () #Get the current column
    new_data = event.GetText() #Get the changed data
    print new_data
    cols = self.list_ctrl.GetColumnCount() #Get the total number of columns
    rows = self.list_ctrl.GetItemCount() #Get the total number of rows

    #Get the changed item use the row_id and iterate over the columns
    print (" ".join([self.list_ctrl.GetItem(row_id, colu_id).GetText() for colu_id in range(cols)]))
    print "Changed Item:", new_data, "Column:", col_id

    #Get the entire listctrl iterate over the rows and the columns within each row
    print "\nEntire listctrl BEFORE the update:"
    for row in range(rows):
        row_data = (" ".join([self.list_ctrl.GetItem(row, col).GetText() for col in range(cols)]))
        print row_data

    #Set the new data in the listctrl
    self.list_ctrl.SetItem(row_id,col_id,new_data)

    print "\nEntire listctrl AFTER the update:"
    #Create a list that can be used to export data to a file
    data_for_export=[]
    for row in range(rows):
        row_data = (" ".join([self.list_ctrl.GetItem(row, col).GetText() for col in range(cols)]))
        print row_data
        data_for_export.append(row_data) #Add to the exportable data

    print "\nData for export"
    for row in data_for_export: #Print the data
        print row

绑定就是这样：

self.list_ctrl.Bind(wx.EVT_LIST_END_LABEL_EDIT, self.OnUpdate)

作为一个例子，我们要说我想编辑蓝色＆＃39;进入黄色＆＃39;。

您与event.GetText()关系密切，请尝试event.GetLabel()，然后不要忘记致电event.Skip()

更新以反映OP最低工作代码：

我没有EditableListCtrl的代码，但我提供了一个工作示例，我假设您的代码可能是什么样子。关于获取选择的问题，您可以致电list_control.GetFirstSelected()来获取所选项目（应该是您正在编辑的项目），然后您可以致电GetItemText。在没有看到EditableListCtrl代码的情况下，我认为你的问题源于一个事件被其他地方捕获并被否决。但这只是猜测。

以下是我认为EditableListCtrl看起来像

的最小工作代码

import wx
from wx.lib.mixins.listctrl import TextEditMixin

class EditableListCtrl(wx.ListCtrl, TextEditMixin):
    def __init__(self, *args, **kw):
        wx.ListCtrl.__init__(self, *args, **kw)
        TextEditMixin.__init__(self)


class MainFrame(wx.Frame):
    def __init__(self, parent=None):
        wx.Frame.__init__(self, parent, id=wx.ID_ANY, title=wx.EmptyString, pos=wx.DefaultPosition,
                          size=wx.Size(762, 347), style=wx.DEFAULT_FRAME_STYLE | wx.TAB_TRAVERSAL)

        self.SetSizeHintsSz(wx.DefaultSize, wx.DefaultSize)

        main_sizer = wx.BoxSizer(wx.VERTICAL)

        self.main_panel = wx.Panel(self, wx.ID_ANY, wx.DefaultPosition, wx.DefaultSize, wx.TAB_TRAVERSAL)
        panel_sizer = wx.BoxSizer(wx.VERTICAL)

        self.list_ctrl = EditableListCtrl(self.main_panel, wx.ID_ANY, wx.DefaultPosition, wx.DefaultSize,
                                     wx.LC_EDIT_LABELS | wx.LC_REPORT) # ---- Changed ------
        panel_sizer.Add(self.list_ctrl, 1, wx.ALL | wx.EXPAND, 5)

        self.main_panel.SetSizer(panel_sizer)
        self.main_panel.Layout()
        panel_sizer.Fit(self.main_panel)
        main_sizer.Add(self.main_panel, 1, wx.EXPAND, 5)

        self.SetSizer(main_sizer)
        self.Layout()

        self.Centre(wx.BOTH)

        self.list_ctrl.InsertColumn(0, "Make")
        self.list_ctrl.InsertColumn(1, "Model")
        self.list_ctrl.InsertColumn(2, "Year")
        self.list_ctrl.InsertColumn(3, "Color")

        rows = [("Ford", "Taurus", "1996", "Blue"),
                ("Nissan", "370Z", "2010", "Green"),
                ("Porche", "911", "2009", "Red")
                ]
        index = 0
        for row in rows:
            self.list_ctrl.InsertStringItem(index, row[0])
            self.list_ctrl.SetStringItem(index, 1, row[1]) # ---- Changed ------
            self.list_ctrl.SetStringItem(index, 2, row[2]) # ---- Changed ------
            self.list_ctrl.SetStringItem(index, 3, row[3]) # ---- Changed ------
            index += 1
        self.list_ctrl.Bind(wx.EVT_LIST_END_LABEL_EDIT, self.OnUpdate)




    def OnUpdate(self, event):
        self.list_ctrl.Select(event.Item.Id) # force the list to select the event item
        row_id = event.GetIndex() #Get the current row
        col_id = event.GetColumn () #Get the current column
        if col_id < 0: # ---- Changed ------
            col_id = 0 # ---- Changed ------
        new_data = event.GetText() #Get the changed data
        print new_data
        cols = self.list_ctrl.GetColumnCount() #Get the total number of columns
        rows = self.list_ctrl.GetItemCount() #Get the total number of rows


        #Get the changed item use the row_id and iterate over the columns
        print (" ".join([self.list_ctrl.GetItem(row_id, colu_id).GetText() for colu_id in range(cols)]))
        print "Changed Item:", new_data, "Column:", col_id

        #Get the entire listctrl iterate over the rows and the columns within each row
        print "\nEntire listctrl BEFORE the update:"
        for row in range(rows):
            row_data = (" ".join([self.list_ctrl.GetItem(row, col).GetText() for col in range(cols)]))
            print row_data

        #Set the new data in the listctrl
        self.list_ctrl.SetStringItem(row_id,col_id,new_data)

        print "\nEntire listctrl AFTER the update:"
        #Create a list that can be used to export data to a file
        data_for_export=[]
        for row in range(rows):
            row_data = (" ".join([self.list_ctrl.GetItem(row, col).GetText() for col in range(cols)]))
            print row_data
            data_for_export.append(row_data) #Add to the exportable data

        print "\nData for export"
        for row in data_for_export: #Print the data
            print row

try:
    app = wx.App()
    frame = MainFrame()
    frame.Show()
    app.MainLoop()
except Exception:
    from traceback import format_exc
    print(format_exc())
    raw_input("")

编辑＃2 由于wx安装之间存在一些差异，因此实施了不同的解决方案。更改了OnUpdate方法并添加了after_edit_event方法

def OnUpdate(self, event):
    event.Skip()
    wx.CallAfter(self.after_edit_event)

def after_edit_event(self):
    rows = self.list_ctrl.GetItemCount()
    cols = self.list_ctrl.GetColumnCount()

    for row in range(rows):
        print(", ".join([self.list_ctrl.GetItem(row, col).GetText() for col in range(cols)]))

编辑后从wx.ListCtrl获取数据
