a problem about wxpython listctrl

Answer 1

Here is a runnable example that works on Windows 7, Python 2.6, wx 2.8.

import wx

class ListTest(wx.Frame):
    def __init__(self, parent, title):
        wx.Frame.__init__(self, parent, -1, title, size=(380, 230))

        panel = wx.Panel(self, -1)

        self.list = wx.ListCtrl(panel, -1, style=wx.LC_REPORT) 
        self.list.InsertColumn(0, 'col 1', width=140)

        hbox = wx.BoxSizer(wx.HORIZONTAL)
        hbox.Add(self.list, 1, wx.EXPAND)
        panel.SetSizer(hbox)
        self.Centre()
        self.Show(True)

        self.Bind(wx.EVT_CHAR_HOOK, self.onKey)

    def onKey(self, evt):
        if evt.GetKeyCode() == wx.WXK_DOWN:
            self.list.InsertStringItem(0, "level 1")
            self.list.InsertStringItem(1, "level 2")
            self.list.SetBackgroundColour(wx.RED)
            self.list.Refresh()

            print self.list.GetItemText(0)
            print self.list.GetItemText(1)
        else:
            evt.Skip()


app = wx.App()
ListTest(None, 'list test')
app.MainLoop()
