wxpython生成的一个简单数据表格操作界面

此代码主要是为了演示如何通过按钮来更新grid的数据

import wx, wx.grid
class GridData(wx.grid.PyGridTableBase):
    _cols = "a b c".split()
    _data = [
        "1 2 3".split(),
        "4 5 6".split(),
        "7 8 9".split()
    ]
    _highlighted = set()
    def GetColLabelValue(self, col):
        return self._cols[col]
    def GetNumberRows(self):
        return len(self._data)
    def GetNumberCols(self):
        return len(self._cols)
    def GetValue(self, row, col):
        return self._data[row][col]
    def SetValue(self, row, col, val):
        self._data[row][col] = val
    def GetAttr(self, row, col, kind):
        attr = wx.grid.GridCellAttr()
        attr.SetBackgroundColour(wx.GREEN if row in self._highlighted else wx.WHITE)
        return attr
    def set_value(self, row, col, val):
        self._highlighted.add(row)
        self.SetValue(row, col, val)
class Test(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None)
        self.data = GridData()
        self.grid = wx.grid.Grid(self)
        self.grid.SetTable(self.data)
        btn = wx.Button(self, label="set a2 to x")
        btn.Bind(wx.EVT_BUTTON, self.OnTest)
        self.Sizer = wx.BoxSizer(wx.VERTICAL)
        self.Sizer.Add(self.grid, 1, wx.EXPAND)
        self.Sizer.Add(btn, 0, wx.EXPAND)
    def OnTest(self, event):
        self.data.set_value(1, 0, "x")
        self.grid.Refresh()
app = wx.PySimpleApp()
app.TopWindow = Test()
app.TopWindow.Show()
app.MainLoop()
