To make your code more readable you may also use the following symbolic constants:
- wxTIMER_CONTINUOUS: Start a normal, continuously running, timer
- wxTIMER_ONE_SHOT: Start a one shot timer
+ Alternatively, use StartOnce().

If the timer was already running, it will be stopped by this method before
restarting it.
