[wxPython-users] binder and events newbie simple question..

[Lanier, Paul]

You can also use evt.GetEventObject() in your handler to get the caselle
that caused the event to happen.

def caselles(evt):
     id_ = evt.GetId() - 5000 # get value 0-99
     n = id_ / 10
     m = id_ % 10
     caselle = evt.GetEventObject()

Make the control ID explicit and analyse it in the handler:
     id_=5000
     for n in range(0,9):
         for m in range(0,9):
             casella = 'casella%dx%d' % (n,m) # more efficient
             casella = wx.lib.intctrl.IntCtrl(parent=self, value=None,
min=1, max=9, id=id_, size=(20,20), limited=True, allow_none=True)
             id_ += 1 # give controls IDs 5000-5099
             casella.Bind(wx.lib.intctrl.EVT_INT, caselles)

def caselles(evt):
     id_ = evt.GetId() - 5000 # get value 0-99
     n = id_ / 10
     m = id_ % 10
     ...

Hope that helps,
