Because for every rule there is an exception. :wink: Timers don't deliver
the events to themselves[*], but to the window that was passed to the
wx.Timer constructor or the SetOwner method.

[*] Actually in a way they do if there is no owner set, but instead of
processing the event normally they call the Notify method of a derived
class. This is done for backwards compatibility with how the timers
used to work before they were taught how to send events to windows.
