public class FullScreenListener
extends AbstractContextListener

Method Summary

void	actionPerformed(FormEvent event)
protected ViewContext	createFullScreenContext(RPCStruct struct, ViewContext vc) Sets the given context to FullScreen mode.
protected void	initialize() Initializes the global variables
protected void	setCurrentContext(ViewContext vc) Takes in viewContext converts it to a html of the viewcontext and display it
protected ViewContext	setToFullScreen(RPCWebEvent rpc) Applies the modules read from the context.properties file to the current context using the data from the session on the defaultContext
protected void	validate(RPCWebEvent rpc) ValidateRPC looks in the RPCStruct for all needed elements and gotoErrorPage in case an element is found or wronglz formated, this is useful so that we won't need to check later for anz variables, simply get them and start Working
protected void	validateBBox(RPCMember bboxRPCMember) Validates the data in the struct to make sure it contains a valid bbox
protected void	validateCntxtProperties() This method checks the context.properties file to make sure that all fields needed are available
protected void	validateLayerList(RPCMember layerListRPCMember) Validates the data in the struct to make sure it contains a valid layerList
