wxPython的 - 如何从自定义对话框WX

Question

得到的返回值这是从wxpython-can we add ok button on pybusyinfo dialog?

跟进的问题，我已经创建了定制dialog.It会弹出当我们从另一个函数调用的函数，如果用户点击“不要继续“按钮在对话框窗口我需要得到真/假值，以确定是否按下特定按钮，并将该值传递给函数调用以进一步处理。

但随着wx自定义对话框，我不能任何返回值，因为对话框一旦我们按任何按钮被破坏。

有没有什么办法通过按钮点击事件从自定义对话框类中获得返回值，并且即使它被销毁也可以从类外部访问。

在此先感谢。

Answer 1

当然。方法EndModal将返回你想要的任何返回码。即

def OnLifeTimer(self, evt): # Update time to live 
     if self.timeoutbutton_pressed == True: 
      return 
     self.life -= 1 
     self.lltime.SetLabelText(str(self.life)) 
     if self.life < 1: 
      self.EndModal(SOME_ID_THAT_YOU_DEFINED_SOMEWHERE_ELSE) 
      self.OnQuit(None) 

传递给EndModal的参数从ShowModal

app = wx.App() 

dlg = Busy(parent = None, msg=msg) 
return_code = dlg.ShowModal() 

返回作为一个侧面说明，你不必调用从对话框内销毁。如果你想从中获取一些标志或其他信息，您可以拨打Destroy后，即

app = wx.App() 

dlg = Busy(parent = None, msg=msg) 
return_value = dlg.ShowModal() 
some_other_value = dlg.some_other_value 
dlg.Destroy()
