Padre::Help - Padre Help Provider API
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:
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)
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.
