python - 使用 GetIndex() 函数

Question

设法修复我的代码。现在的事情是我试图调用一个事件来使用 getIndex() 来提取当前选定的 listctrl 项目的索引。我知道我需要为事件传递一个变量，但代码一直在提示我必须声明它..或者如果我实际上在 evt_itemselected 绑定(bind)中使用事件..它说我没有这样的名为事件的变量....可以'似乎找不到类似情况的任何例子...有人可以启发我吗？

如果名称 == '主要': main()

Answer 1

问题出在代码部分:

  return self.entry
  self.closeOK
  self.CloseDial

closeOk 和 CloseDial 永远不会被调用，因为它们位于 return 语句之后。
