\section{\class{wxHelpProvider}}\label{wxhelpprovider}
|
|
|
|
wxHelpProvider is an abstract class used by a program implementing context-sensitive help to
|
|
show the help text for the given window.
|
|
|
|
The current help provider must be explicitly set by the application using
|
|
wxHelpProvider::Set().

\membersection{wxHelpProvider::\destruct{wxHelpProvider}}\label{wxhelpproviderdtor}
|
|
|
|
\func{}{\destruct{wxHelpProvider}}{\void}
|
|
|
|
Virtual destructor for any base class.
|
|
|
|
\membersection{wxHelpProvider::Set}\label{wxhelpproviderset}
|
|
|
|
\func{wxHelpProvider*}{Set}{\param{wxHelpProvider* }{helpProvider}}
|
|
|
|
Get/set the current, application-wide help provider. Returns
|
|
the previous one.
|
|
|
|
\membersection{wxHelpProvider::Get}\label{wxhelpproviderget}
|
|
|
|
\func{wxHelpProvider*}{Get}{\void}
|
|
|
|
Unlike some other classes, the help provider is not created on demand.
|
|
This must be explicitly done by the application.
|
|
|
|
\membersection{wxHelpProvider::GetHelp}\label{wxhelpprovidergethelp}
|
|
|
|
\func{wxString}{GetHelp}{\param{const wxWindowBase* }{window}}
|
|
|
|
Gets the help string for this window. Its interpretation is dependent on the help provider
|
|
except that empty string always means that no help is associated with
|
|
the window.
|
|
|
|
\membersection{wxHelpProvider::ShowHelp}\label{wxhelpprovidershowhelp}
|
|
|
|
\func{bool}{ShowHelp}{\param{wxWindowBase* }{window}}
|
|
|
|
Shows help for the given window. Uses \helpref{GetHelp}{wxhelpprovidergethelp} internally if
|
|
applicable.
|
|
|
|
Returns TRUE if it was done, or FALSE if no help was available
|
|
for this window.
|
|
|
|
\membersection{wxHelpProvider::AddHelp}\label{wxhelpprovideraddhelp}
|
|
|
|
\func{void}{AddHelp}{\param{wxWindowBase* }{window}, \param{const wxString\& }{text}}
|
|
|
|
Associates the text with the given window or id. Although all help
|
|
providers have these functions to allow making \helpref{wxWindow::SetHelpText}{wxwindowsethelptext}
|
|
work, not all of them implement the functions.
|
|
|
|
\func{void}{AddHelp}{\param{wxWindowID }{id}, \param{const wxString\& }{text}}
|
|
|
|
This version associates the given text with all windows with this id.
|
|
May be used to set the same help string for all Cancel buttons in
|
|
the application, for example.
