对话框不能退出
dialog = wx.TextEntryDialog(self, 'What is your favorite programming language?','对话框')
dialog.SetMaxLength(35)
if dialog.ShowModal() == wx.ID_OK: # 如果用户单击了 OK 按钮
self.name = dialog.GetValue()
弹出对话框后，按下对话框上的取消键不能退出对话框窗口，请问应该怎么样办
我这测试是可以的，是不是你自己的操作问题？ zltzlt 发表于 2020-8-13 09:32

我也没改动什么东西，然后点对话框右上角的 'x'也不能退出 zltzlt 发表于 2020-8-13 09:32

运行你的原程序没问题，我把这个功能插到我的程序里就不能正常退出了 A.Lyapunov 发表于 2020-8-13 09:41
