	10	@class wxTipProvider
	11
	12	This is the class used together with wxShowTip() function.
	13	It must implement wxTipProvider::GetTip function and return the
	14	current tip from it (different tip each time it is called).
	15
	16	You will never use this class yourself, but you need it to show startup tips
	17	with wxShowTip. Also, if you want to get the tips text from elsewhere than a
	18	simple text file, you will want to derive a new class from wxTipProvider and
	19	use it instead of the one returned by wxCreateFileTipProvider().
