| 2 | ||
| 3 | wxHelpProvider is an abstract class used by a program implementing context-sensitive help to | |
| 4 | show the help text for the given window. | |
| 5 | ||
| 6 | The current help provider must be explicitly set by the application using | |
| 7 | wxHelpProvider::Set(). | |

| 26 | ||
| 27 | \func{}{\destruct{wxHelpProvider}}{\void} | |
| 28 | ||
| 29 | Virtual destructor for any base class. | |
| 30 | ||
| 31 | \membersection{wxHelpProvider::Set}\label{wxhelpproviderset} | |
| 32 | ||
| 33 | \func{wxHelpProvider*}{Set}{\param{wxHelpProvider* }{helpProvider}} | |
| 34 | ||
| 35 | Get/set the current, application-wide help provider. Returns | |
| 36 | the previous one. | |
| 37 | ||
| 38 | \membersection{wxHelpProvider::Get}\label{wxhelpproviderget} | |
| 39 | ||
| 40 | \func{wxHelpProvider*}{Get}{\void} | |
| 41 | ||
| 42 | Unlike some other classes, the help provider is not created on demand. | |
| 43 | This must be explicitly done by the application. | |
| 44 | ||
| 45 | \membersection{wxHelpProvider::GetHelp}\label{wxhelpprovidergethelp} | |
| 46 | ||
| 47 | \func{wxString}{GetHelp}{\param{const wxWindowBase* }{window}} | |
| 48 | ||
| 49 | Gets the help string for this window. Its interpretation is dependent on the help provider | |
| 50 | except that empty string always means that no help is associated with | |
| 51 | the window. | |
| 52 | ||
| 53 | \membersection{wxHelpProvider::ShowHelp}\label{wxhelpprovidershowhelp} | |
| 54 | ||
| 55 | \func{bool}{ShowHelp}{\param{wxWindowBase* }{window}} | |
| 56 | ||
| 57 | Shows help for the given window. Uses \helpref{GetHelp}{wxhelpprovidergethelp} internally if | |
| 58 | applicable. | |
| 59 | ||
| 60 | Returns TRUE if it was done, or FALSE if no help was available | |
| 61 | for this window. | |
| 62 | ||
| 63 | \membersection{wxHelpProvider::AddHelp}\label{wxhelpprovideraddhelp} | |
| 64 | ||
| 65 | \func{void}{AddHelp}{\param{wxWindowBase* }{window}, \param{const wxString\& }{text}} | |
| 66 | ||
| 67 | Associates the text with the given window or id. Although all help | |
| 68 | providers have these functions to allow making \helpref{wxWindow::SetHelpText}{wxwindowsethelptext} | |
| 69 | work, not all of them implement the functions. | |
| 70 | ||

71 | \func{void}{AddHelp}{\param{wxWindowID }{id}, \param{const wxString\& }{text}} |
| 72 | ||
| 73 | This version associates the given text with all windows with this id. | |
| 74 | May be used to set the same help string for all Cancel buttons in | |
| 75 | the application, for example. | |
