Python 消除wx.Grid中的拖动选择

我试图找出如何消除wx.Grid中默认的拖动行为。我希望最终得到一个用户根本无法拖动的网格

我（最终）找到了MouseEventsManager，它看起来很理想，但没有达到我的预期：

import wx
import wx.grid as gridlib

class GridMouseEventsManager(wx.MouseEventsManager):
    def MouseDragBegin(self, item, pos):
        return False

class MyForm(wx.Frame):

    def __init__(self):
        wx.Frame.__init__(self, None, wx.ID_ANY, "Sample grid")

        self.grid = gridlib.Grid(self)
        self.grid.CreateGrid(5,4)
        self.grid.SetCellSize(4,1,1,2)

        self.grid.SetColLabelSize(0)            # eliminates spreadsheet-style row & col headers
        self.grid.SetRowLabelSize(0)

        rowHeight = 50
        colWidth  = 50
        for i in range(1,5):
            self.grid.SetRowSize(i, rowHeight)
        for i in range(0,4):
            self.grid.SetColSize(i, colWidth)

        self.grid.SetCellBackgroundColour(4, 3, wx.LIGHT_GREY)

        # self.grid.SetCellHighlightPenWidth(0)   # eliminates highlighted cell, i.e., 'current' cell in spreadsheet
        self.grid.EnableCellEditControl(False)
        self.grid.Bind(gridlib.EVT_GRID_SELECT_CELL, self.GridSelect, self.grid)

        self.grid_mouse_events_manager = GridMouseEventsManager(self.grid)

        self.Bind(wx.EVT_CLOSE, self.on_exit)

        mainSizer = wx.BoxSizer(wx.VERTICAL)
        mainSizer.Add(self.grid, 0, wx.ALIGN_CENTER)

        self.selectedRow = -1
        self.selectedCol = -1

        self.SetSizerAndFit(mainSizer)
        # self.ShowFullScreen(True)

    def GridSelect(self, event):

        col = event.GetCol()
        row = event.GetRow()

        penWidth = 0
        if col == 1:
            penWidth = 2

        self.grid.SetCellHighlightPenWidth(penWidth)

        self.Refresh()

    def on_exit(self, event):
        self.grid_mouse_events_manager.Destroy()
        self.Destroy()

# Run the program
if __name__ == "__main__":
    app = wx.App()
    frame = MyForm().Show()
    app.MainLoop()

这仍然具有默认行为，即当用户单击并拖动时选择多个单元格。我想完全禁用拖动和/或多个单元格选择

我对Python相当陌生，甚至对wxPython也比较新；我还没有找到一个解释或例子来说明如何做到这一点。我用

self

对象和

grid

对象尝试了MouseEventsManager构造函数，这两种方法似乎都没有任何效果

这是怎么做到的？

那么，你难道不知道在wxpython.org上再搜索一次就得到了我想要的吗

self.grid.GetGridWindow().Bind(wx.EVT_MOTION, self.OnMotion)

...

def OnMotion(self, event)
    # just trap this event and prevent it from percolating up the window hierarchy
    pass

那正是我想要的
