Infinite recursion calling superclass EndEdit() in a GridCellNumberEditor subclass

[andreamerello]

Operating system: Ubuntu 20.04
wxPython version & source: 4.2.1 (conda)
Python version & source: 3.12.2 (conda)

This has been reproduced also by other users

Description of the problem:

I end up in infinite recursion, with the following error getting printed on the console

...
...
End edit enter
End edit enter
object address  : 0x7ff66a8bd240
object refcount : 3
object type     : 0x55fb65c4e7e0
object type name: RecursionError
object repr     : RecursionError('maximum recursion depth exceeded while calling a Python object')
lost sys.stderr
End edit exit
End edit exit
...
...

This happens by doing those apparently licit steps:

• Subclass GridCellNumberEditor
• Override EndEdit()
• Invoke the superclass EndEdit() method from within by overridden EndEdit() method

import wx
import wx.grid as gridlib

class MyGridCellNumberEditor(gridlib.GridCellNumberEditor):
    def EndEdit(self, row, col, grid, oldval):
        print(f"End edit enter")
        super().EndEdit(row, col, grid, oldval)
        print(f"End edit exit")

class MyGrid(gridlib.Grid):
    def __init__(self, parent):
        super().__init__(parent, -1)
        self.CreateGrid(1, 1)
        self.SetCellEditor(0, 0, MyGridCellNumberEditor())

class MyFrame(wx.Frame):
    def __init__(self):
        super().__init__(None, title="Custom GridCellNumberEditor Example")
        panel = wx.Panel(self)
        grid = MyGrid(panel)
        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.Add(grid, 1, wx.EXPAND)
        panel.SetSizer(sizer)
        self.SetSize((400, 300))

class MyApp(wx.App):
    def OnInit(self):
        frame = MyFrame()
        frame.Show()
        return True

if __name__ == "__main__":
    app = MyApp(False)
    app.MainLoop()
