[wxPython] wxGrid autoend cell edit control

This small idea enhances user experience with wxGrid:

class Grid(wxGrid):

     def __init__(*arg,**kw):
         wxGrid.__init__( *arg,**kw )
         self = arg[0]
         EVT_GRID_EDITOR_CREATED(self, self.OnEditorCreated)

     def OnEditorCreated( self, event ):
         eh = wxEvtHandler()
         eh.Connect(-1, -1, wxEVT_KILL_FOCUS,self.HandleControlKillFocus)
         w = event.GetControl()
         w.PushEventHandler( eh )
         event.Skip()

     def HandleControlKillFocus( self, event ):
         self.DisableCellEditControl()
         event.Skip()

When user leaves edit control for whatever reason it is automaticaly closed.

Is it worth for inclusion in wxWindows?

Perhaps as a MixIn. See wxPython.liib.mixins.grid.

I noted that after using it i got many leaks of wxGridCellEditorEvtHandler

Checking source found that grid conditionaly pushes such object and at
end unconditionaly pops one. Apparently it pops my handler. Should i put
these functions into C++ code to avoid leaks?

Perhaps you could push the handler in EVT_GRID_EDITOR_SHOWN and pop it in EVT_GRID_EDITOR_HIDDEN?
