【问题描述】：

我正在寻找一种方法让用户在 wxPython 网格中批量编辑数据，有点像在 Excel 中选择一个范围、键入数据并按 shift-Enter。这是我的网格的简化版本：

class MyGrid(gridlib.Grid):
    def __init__(self, panel):
        gridlib.Grid.__init__(self, panel)
        self.Bind(gridlib.EVT_GRID_CELL_CHANGE, self.onEditCell)
        self.Bind(gridlib.EVT_GRID_RANGE_SELECT, self.onSelection)

    def onSelection(self, event):
        if self.GetSelectionBlockTopLeft() == []:
            self.selected_row_number = 0
            self.selected_col_number = 0
        else:
            self.selected_row_number = self.GetSelectionBlockBottomRight()[0][0] - self.GetSelectionBlockTopLeft()[0][0] + 1
            self.selected_col_number = self.GetSelectionBlockBottomRight()[0][1] - self.GetSelectionBlockTopLeft()[0][1] + 1
        print self.selected_row_number, self.selected_col_number

    def onEditCell(self,event):
        print self.selected_row_number, self.selected_col_number

问题似乎是 onEditCell 事件覆盖了之前的选择。所以我可以选择例如网格中的四乘四块，onSelection 将打印 4 4。但是当我开始键入并按 Enter 时，onEditCell 将打印 0,0，就好像只选择了我正在编辑的单元格一样。如何保持选择了多少个单元格的“记忆”？谢谢，

回答我自己的问题：我可以让它与一个看起来不像是正确的做事方式的丑陋黑客一起工作：

def onSelection(self, event):
    self.previous_selected_row_number = self.selected_row_number
    self.previous_selected_col_number = self.selected_col_number
    if self.GetSelectionBlockTopLeft() == []:
        self.selected_row_number = 0
        self.selected_col_number = 0
    else:
        self.selected_row_number = self.GetSelectionBlockBottomRight()[0][0] - self.GetSelectionBlockTopLeft()[0][0] + 1
        self.selected_col_number = self.GetSelectionBlockBottomRight()[0][1] - self.GetSelectionBlockTopLeft()[0][1] + 1
    print self.selected_row_number, self.selected_col_number
    print self.previous_selected_row_number, self.previous_selected_col_number



def onEditCell(self,event):
    print self.previous_selected_row_number, self.previous_selected_col_number

如果有人能想到更好的方法……
