Defined in:
lib/rsence/plugins/guiparser.rb

Overview

This class automatically loads a YAML file from “gui” subdirectory of a plugin.

Extend your plugin from the GUIPlugin class instead of the Plugin class to make this work automatically.

Examples:

Initialize like this from inside a plugin method. This will load the “gui/my_gui.yaml” file.

gui = GUIParser.new( self, 'my_gui' )

To make the client render the contents of the yaml do this:

ses = get_ses( msg )
params = { :values => @gui.values( ses ) }
gui.init( msg, params )
