	1	\section{\class{wxTipProvider}}\label{wxtipprovider}
	2
	3	This is the class used together with \helpref{wxShowTip}{wxshowtip} function.
	4	It must implement \helpref{GetTip}{wxtipprovidergettip} function and return the
	5	current tip from it (different tip each time it is called).
	6
	7	You will never use this class yourself, but you need it to show startup tips
	8	with wxShowTip. Also, if you want to get the tips text from elsewhere than a
	9	simple text file, you will want to derive a new class from wxTipProvider and
	10	use it instead of the one returned by \helpref{wxCreateFileTipProvider}{wxcreatefiletipprovider}.

	29
	30	Constructor.
	31
	32	\docparam{currentTip}{The starting tip index.}

	34	\membersection{wxTipProvider::GetTip}\label{wxtipprovidergettip}
	35
	36	\func{wxString}{GetTip}{\void}
	37
	38	Return the text of the current tip and pass to the next one. This function is
	39	pure virtual, it should be implemented in the derived classes.

	41	\membersection{wxTipProvider::PreprocessTip}\label{wxtipproviderpreprocesstip}
	42
	43	\func{virtual wxString}{PreProcessTip}{\param{const wxString\&}{tip}}
	44
	45	Returns a modified tip. This function will be called immediately after read,
	46	and before being check whether it is a comment, an empty string or a string
	47	to translate. You can optionally override this in your custom user-derived class
	48	to optionally to modify the tip as soon as it is read. You can return any
	49	modification to the string. If you return wxEmptyString, then this tip is
	50	skipped, and the next one is read.
	51
	52	\membersection{wxCurrentTipProvider::GetCurrentTip}\label{wxtipprovidergetcurrenttip}
	53
	54	\constfunc{size\_t}{GetCurrentTip}{\void}
	55
	56	Returns the index of the current tip (i.e. the one which would be returned by
	57	GetTip).
	58
	59	The program usually remembers the value returned by this function after calling
	60	\helpref{wxShowTip}{wxshowtip}. Note that it is not the same as the value which
	61	was passed to wxShowTip $+ 1$ because the user might have pressed the "Next"
	62	button in the tip dialog.
