wx.grid不更新行數

Question

我試圖通過在更改表數據後調用grid.ForceRefresh（）來更新wx.grid.PyGridTableBase。但是，行數不會刷新，所以表仍然顯示原始（更新前）行數。我能做些什麼來完全更新網格？

您可能忘記通知網格您所做的更改。你可以找到在wxPython的演示一個例子，也可以直接閱讀本舊線的題目

它說：

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 
    ) 

其次

self.GetView().ProcessTableMessage(msg)
