我正在尝试将用户选择的目录传递回名为wx.TextCtrlChooseRoot。到目前为止,这还没有奏效。

我究竟做错了什么?我尝试了其他操作,但是挂起了或者收到了此错误消息。

OnChooseRoot中的文件“F:\ Indexinator3000_x64.pyw”,第78行
self.ChooseRoot.SetValue(“Hello”)

最佳答案

仔细阅读我在您以前的question中给您的建议。特别:

  • 对小部件使用对象属性,因此您不会松散跟踪它们(self.ChooseRoot =...)
  • 使用更多描述性小部件名称(self.labelChooseRoot)

  • __init__方法(也称为构造函数)之外,您无法跟踪小部件。您必须将它们作为属性添加到MainPanel对象。
    class MainPanel(wx.Panel):
        def __init__(self, parent, id):
            ...
            self.ChooseRoot = wx.TextCtrl(self, size=(210, -1))
            ...
    
        def OnChooseRoot(self, event=None):
            ...
            self.ChooseRoot.SetValue(RootPath)
            ...
    

    我还建议您阅读一些有关OOP概念的文章。也许您可以从here开始。

    编辑:
    您差点让它工作了。这个想法还可以,您只是忘记了几个地方。我已经更新了您的代码以符合我的“标准”,删除了一些不必要的复制/粘贴内容和其他一些小的调整。如果需要,请使用一些比较软件并进行仔细的比较以查看更改。
