NAME
Padre::Help - Padre Help Provider API
DESCRIPTION
The Padre::Help
class provides a base class, default implementation and API documentation for help provision support in Padre.
In order to setup a help system for a document type called XYZ
one has to do the following: Create a module called Padre::Help::XYZ
that subclasses the Padre::Help
module and override 3 methods: help_init
, help_list
and help_render
.
In the class representing the Document (Padre::Document::XYZ
) one should override the get_help_provider
method and return an object of the help provide module. In our case it should contain
require Padre::Help::XYZ;
return Padre::Help::XYZ->new;
(TO DO: Maybe it should only return the name of the module)
The help_init
method is called by the new method of Padre::Help
once for every document of XYZ
kind. (TO DO: maybe it should be only once for every document type, and not once for every document of that type).
help_list
should return a reference to an array holding the possible strings the system can provide help for.
help_render
is called by one of the keywords, it should return the HTML to be displayed as help and another string which is the location of the help. Usually a path to a file that will be used in the title of the window.
