| | 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(). |

| | 25 | \membersection{wxHelpProvider::\destruct{wxHelpProvider}}\label{wxhelpproviderdtor} |
| | 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. |
| | 76 | |
| | 77 | \membersection{wxHelpProvider::RemoveHelp}\label{wxhelpproviderremovehelp} |
| | 78 | |
| | 79 | \func{void}{RemoveHelp}{\param{wxWindowBase* }{window}} |
| | 80 | |
| | 81 | Removes the association between the window pointer and the help text. This is |
| | 82 | called by the wxWindow destructor. Without this, the table of help strings will fill up |
| | 83 | and when window pointers are reused, the wrong help string will be found. |
