Wxpython回调

我的框架中有3个控件-

包含员工表中员工姓名列表的列表框

接受新员工姓名的文本框

单击一个命令按钮将在employee表中插入一个新名称

要求：

一旦我在插入新行后按下submit按钮，列表框就会自动用新名称刷新

我如何完成这项任务

我成功地创建了控件，绑定了一个点击事件并插入了一行。但无法刷新列表框

提前感谢您的帮助。

您应该使用列表框的SetItems方法：

import wx

class MyPanel(wx.Panel):
    """"""

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

        self.choices = ["George Lucas"]
        self.lbox = wx.ListBox(self, choices=self.choices)
        self.new_emp = wx.TextCtrl(self)
        addBtn = wx.Button(self, label="Add Employee")
        addBtn.Bind(wx.EVT_BUTTON, self.addEmployee)

        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.Add(self.lbox, 0, wx.ALL|wx.EXPAND, 5)
        sizer.Add(self.new_emp, 0, wx.ALL|wx.EXPAND, 5)
        sizer.Add(addBtn, 0, wx.ALL, 5)
        self.SetSizer(sizer)

    #----------------------------------------------------------------------

        emp = self.new_emp.GetValue()
        self.choices.append(emp)
        self.lbox.SetItems(self.choices)
        self.new_emp.SetValue("")

        panel = MyPanel(self)
