我正试图根据我的数据的某一列中的文本值过滤objectlistview。我不知道如何正确地构造过滤器。我一直在说:
http://objectlistview.sourceforge.net/python/features.htmlhttp://objectlistview.sourceforge.net/python/majorClasses.html
我能够获得Filter. head (n)成功工作，但无法获得Filter。TextSearch(objectListView, columns=()， text=")工作，因为我不明白参数类型应该是什么。
我写了下面的代码:def OnFilterMeter(self,event):
list = self.exception_panel.col_list ## The lenght of my column list
col = list[len(list)-1] ## I want to search the last column
meter_flt = Filter.TextSearch(self.exception_panel,columns = (col), text = "10") ## Create filter to find string 10 in last column
self.exception_panel.SetFilter(meter_flt)
self.exception_panel.populate()
我不明白为什么这不起作用。当程序试图再次填充列表视图时，它不会过滤列表。至少它应该显示所有的空格，因为它找不到任何等于"10"的项。请帮助。谢谢你
下面是我的代码:class Display_Manager(wx.Frame):

下面的工作对我来说，它对第二列进行搜索，它只显示一个匹配的条目。
