Запись на второй кадр из первого кадра с использованием wxPython

Question

Первая попытка использования GUI с использованием wxpython. Я пытаюсь написать из основного фрейма «MyForm» во второй кадр, который является формой gridlayout. Я продолжаю работать: AttributeError: объект 'MyForm' не имеет атрибута 'myGrid'

Ниже мой код, ошибка возникает в строке 120. Я полагаю, что он застрял в MyForm, я просто не уверен, как получить из него.

Answer 1

myGrid является атрибутом gridForm класса, поэтому self.myGrid не будет работать внутри MyForm, как в MyFormself является экземпляром класса MyForm и не gridForm. Существует много альтернатив тому, что вы хотите выполнить. Два из них являются:

• вы можете обернуть вызовы SetCellValue в метод gridForm и вызвать новый метод, как frame.SetCellValueWrapper()

следующим образом:

class gridForm(wx.Frame): 
    def __init__(self): 
     wx.Frame.__init__(self, None, wx.ID_ANY, "Drill Down Data", size = (1000,1000)) 

     panel = wx.Panel(self) 

     self.myGrid = gridlib.Grid(panel) 
     self.myGrid.CreateGrid(12, 8) 

     self.sizer = wx.BoxSizer(wx.VERTICAL) 
     self.sizer.Add(self.myGrid, 1, wx.EXPAND) 
     panel.SetSizer(self.sizer) 

    def SetCellValueWrapper(self): 
     self.myGrid.SetCellValue(0,0, "Failure") #here is where ir starts 
     self.myGrid.SetCellValue(0,1, "Count") 
     self.myGrid.SetCellValue(0,3, "Percent Total") 

---

def compMonth(self, event): 
    frame = gridForm() 
    frame.SetCellValueWrapper() 
    frame.Show() 

• или вы можете напрямую получить доступ к myGrid и вызвать метод.

как этот

def compMonth(self, event): 
    frame = gridForm() 
    frame.myGrid.SetCellValue(0,0, "Failure") #here is where ir starts 
    frame.myGrid.SetCellValue(0,1, "Count") 
    frame.myGrid.SetCellValue(0,3, "Percent Total") 
    frame.Show()
