如何修改 Frame Class 中的 Grid 单元格？

Question

我正在尝试将网格 table 在对其进行一些修改（添加了一些文本并更改了背景）之后将其重置为初始状态。我的第一个想法是执行 ForceRefresh()，但它似乎不起作用。之后，我想我只需要将背景设置为白色并将 SetCellValue 设置为空白以模拟刷新，但它也不起作用。

当我使用：

self.SetCellBackgroundColour(0, 16, "#ffffff")

我收到这个错误：

AttributeError: 'TestFrame' object has no attribute 'SetCellBackgroundColour'

我的主要问题是如何从框架 class 修改我的网格中的内容。我确定我做的不对，因此我的问题在这里。

如果有人能帮助我解决我的问题，我将不胜感激。

这是我的代码中有问题的部分（参见最后的 def）：

import wx
import wx.grid as gridlib

class SimpleGrid(gridlib.Grid): ##, mixins.GridAutoEditMixin):
    def __init__(self, parent, log):
        gridlib.Grid.__init__(self, parent, -1)

        [... Some Code to Create the grid]

class TestFrame(wx.Frame):
    def __init__(self, parent, log):
        wx.Frame.__init__(self, parent, 0, "Native Ads Reports V1.0", size=(1400,800))
        self.grid = SimpleGrid(self, log)

        # Create a status-Bar
        status = self.CreateStatusBar()

        # Create menu & Items
        menubar = wx.MenuBar()
        first = wx.Menu()
        applyItem = first.Append(wx.ID_ANY, "Apply Changes", "This apply all changes to the campaigns" )
        resetItem = first.Append(wx.ID_ANY, "Reset Changes", "This Reset all changes to the campaigns" )
        menubar.Append(first, "Action")
        self.SetMenuBar(menubar)

        # Associate a handler function with the EVT_MENU
        self.Bind(wx.EVT_MENU, self.OnApply, applyItem)
        self.Bind(wx.EVT_MENU, self.OnReset, resetItem)

    def OnApply(self, event):
            """Apply all changes"""
            dlg = wx.MessageDialog(None, "Do you want to apply changes?",'Updater',wx.YES_NO | wx.ICON_QUESTION)
            result = dlg.ShowModal()
            if result == wx.ID_YES:
                self.count()
                from changeBid import changeBid
                changeBidTbBulk()

    #My problem is situated here. If the user clicks "Yes" in the dialog box the table should reset and all modifications should be deleted
    def OnReset(self, event):
            """Apply all changes"""
            dlg = wx.MessageDialog(None, "Do you want to reset all changes?",'Updater',wx.YES_NO | wx.ICON_QUESTION)
            result = dlg.ShowModal()
            if result == wx.ID_YES:
                db_conn.execute("DELETE FROM SandboxTB")
                db_conn.execute("DELETE FROM SandboxOB")
                db_conn.commit() 
                # Here I tried to change background
                self.SetCellBackgroundColour(0, 16, "#ffffff")
                #and here the refresh
                self.ForceRefresh()

谢谢，

我用了 self.grid.SetCellBackgroundColour 并且有效。
