使用wxPython从第一帧写入第二帧

使用wxpython首次尝试GUI。我试图从主框架“MyForm”写入第二个框架，即gridlayout表单。我经常遇到： AttributeError:“MyForm”对象没有属性“myGrid”

下面是我的代码，错误发生在第120行。我意识到它被困在我的身体里，我只是不知道如何摆脱它

myGrid

是

gridForm

类的一个属性，这就是

self的原因。myGrid

不会在

MyForm

中工作，因为在

MyForm

中

self

是类

MyForm

的一个实例，而不是

gridForm

。除了你想要完成的事情，还有很多选择。其中两项是：

• 您可以将对

  SetCellValue

  的调用封装到

  gridForm

  的方法中，并将新方法称为

  frame.SetCellValueWrapper（）

详情如下:

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")

---

• 或者您可以直接访问

  myGrid

  ，并调用该方法

像这样

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()

---

现在想想，如果我能在“MyForm”中插入网格，我就不会有这个问题了，这比使用第二个框架更容易。这方面的任何帮助都会起作用。关于如何选择框架打开的窗口位置，有什么想法吗？例如，我希望第一个帧在屏幕的左侧打开，第二个帧在右侧打开。您可以向

wx.Frame

的构造函数提供位置参数，例如：

wx.Frame.\uuuuuu init\uuuuuuuuuuu（self，None，wx.ID\uany，“深入数据”，size=（10001000），pos=wx.Point（x，y））

再次感谢您，那太完美了。还有一个问题：），函数lastMonth会打开gridform，但是如果在不关闭gridform的情况下再次运行该函数，则程序会崩溃。在lastMonth函数中是否有关闭gridform窗口（如果打开）的方法？

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()
