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}. | |

32 | \func{}{wxTipProvider}{\param{size\_t }{currentTip}} | |
33 | ||
34 | Constructor. | |
35 | ||
36 | \docparam{currentTip}{The starting tip index.} | |
37 | ||
38 | \membersection{wxTipProvider::GetTip}\label{wxtipprovidergettip} | |
39 | ||
40 | \func{wxString}{GetTip}{\void} | |
41 | ||
42 | Return the text of the current tip and pass to the next one. This function is | |
43 | pure virtual, it should be implemented in the derived classes. | |
44 | ||
45 | \membersection{wxTipProvider::PreprocessTip}\label{wxtipproviderpreprocesstip} | |
46 | ||
47 | \func{virtual wxString}{PreProcessTip}{\param{const wxString\&}{tip}} | |
48 | ||
49 | Returns a modified tip. This function will be called immediately after read, | |
50 | and before being check whether it is a comment, an empty string or a string | |
51 | to translate. You can optionally override this in your custom user-derived class | |
52 | to optionally to modify the tip as soon as it is read. You can return any | |
53 | modification to the string. If you return wxEmptyString, then this tip is | |
54 | skipped, and the next one is read. | |
55 | ||
56 | \membersection{wxCurrentTipProvider::GetCurrentTip}\label{wxtipprovidergetcurrenttip} | |
57 | ||
58 | \constfunc{size\_t}{GetCurrentTip}{\void} | |
59 | ||
60 | Returns the index of the current tip (i.e. the one which would be returned by | |
61 | GetTip). | |
62 | ||
63 | The program usually remembers the value returned by this function after calling | |
64 | \helpref{wxShowTip}{wxshowtip}. Note that it is not the same as the value which | |
65 | was passed to wxShowTip $+ 1$ because the user might have pressed the "Next" | |
66 | button in the tip dialog. | |
