/**
@class wxTimer
The wxTimer class allows you to execute code at specified intervals. Its
precision is platform-dependent, but in general will not be better than 1ms nor
worse than 1s.
The wxTimer class allows you to execute code at specified intervals.
Its precision is platform-dependent, but in general will not be better than
@c 1ms nor worse than @c 1s.
There are three different ways to use this class:
You may derive a new class from wxTimer and override the
wxTimer::Notify member to perform the required action.
Or you may redirect the notifications to any
wxEvtHandler derived object by using the non-default
constructor or wxTimer::SetOwner. Then use the @c EVT_TIMER
macro to connect it to the event handler which will receive
wxTimerEvent notifications.
Or you may use a derived class and the @c EVT_TIMER
macro to connect it to an event handler defined in the derived class.
If the default constructor is used, the timer object will be its
own owner object, since it is derived from wxEvtHandler.

In any case, you must start the timer with wxTimer::Start
after constructing it before it actually starts sending notifications. It can
be stopped later with wxTimer::Stop.

It can be stopped later with wxTimer::Stop().
@note A timer can only be used from the main thread.
