Python 编辑后从wx.ListCtrl获取数据
如果我创建一个wx.ListCtrl并使用mixin使我能够编辑它,那么如何从更改的单元格中获取数据?到目前为止,我有下面的代码。当我试图打印它/将它保存在变量中时,它是空的Python 编辑后从wx.ListCtrl获取数据,python,wxpython,Python,Wxpython,如果我创建一个wx.ListCtrl并使用mixin使我能够编辑它,那么如何从更改的单元格中获取数据?到目前为止,我有下面的代码。当我试图打印它/将它保存在变量中时,它是空的 def __init__(self, parent): """Constructor""" wx.Panel.__init__(self, parent) rows = [("Ford", "Taurus&q

绑定是这样的:
self.list_ctrl.Bind(wx.EVT_LIST_END_LABEL_EDIT, self.OnUpdate)
例如,假设我想将“蓝色”编辑为“黄色”。您已接近
event.GetText()
,请尝试event.GetLabel()
,然后不要忘记调用event.Skip()

我没有你的EditableListCtrl
的代码,但是我已经提供了一个工作示例,我假设你的代码可能是这样的。对于有关获取选择的问题,您可以通过调用list\u control.GetFirstSelected()
获取所选项目(应该是您正在编辑的项目),并从中调用GetItemText
。如果没有看到EditableListCtrl
代码,我会假设您的问题源于某个事件在其他地方被捕获并被否决。但这只是一个猜测
下面是一些我假设EditableListCtrl
看起来最简单的工作代码
