Answer 1

import wx

class GraphicsPage(wx.grid.Grid):

    def __init__(self, parent, width, height): 
        super(GraphicsPage, self).__init__(parent, -1) 
        self.CreateGrid(width, height) 

        self.SetRowLabelSize (0) 
        self.SetMargins(0,0) 
        self.AutoSizeColumns(False) 
        self.ForceRefresh()

然后用：

实例化它

GraphicsPage (someParent, 20, 30)
