Question

我正在尝试通过在更改表数据后调用grid.ForceRefresh（）来更新wx.grid.PyGridTableBase。但是，行数不会刷新，因此表仍显示原始（更新前）行数。有什么办法可以完全更新网格吗？

您可能忘记通知网格您所做的更改。您可以在wxPython演示中找到一个示例，或者您可以在主题上阅读这个旧主题：

https://groups.google.com/forum/?fromgroups=#!msg/wxpython-users/z4iobAKq0os/zzUL70WzL_AJ

其中说：

msg = wx.grid.GridTableMessage(self,          # The table
      wx.grid.GRIDTABLE_NOTIFY_ROWS_APPENDED, # what we did to it
      1                                       # how many
      )

或

msg = wx.grid.GridTableMessage(self,          # The table
      wx.grid.GRIDTABLE_NOTIFY_ROWS_INSERTED, # what we did to it
      5,                                      # from which row
      1                                       # how many
      )

或

msg = wx.grid.GridTableMessage(self,          # The table
      wx.grid.GRIDTABLE_NOTIFY_ROWS_DELETED,  # what we did to it
      5,                                      # from which row
      1                                       # how many
      )

接着是

self.GetView().ProcessTableMessage(msg)
