Little help needed on the roSearchScreen

Archived
1

Hi everyone,

I am trying to implement roku search functionality using the suggestions from the component reference guide and this post( http://forums.roku.com/viewtopic.php?f=34&t=30099&p=184075&hilit=rosearchscreen#p184075) by roku team.

I was able to retrive the searchresults from the server, parse it in to roArray. But I am not able to get to display them on the ‘roPosterScreen’. I am not sure why the posterscreen is not displaying. Below is the code i am using.

Could anybody shed some light on this as I am stuck here forever trying to figure out what is preventing ‘roPosterScreen’ from being displayed?


function GenerateSearchResults(partSearchText As String, screen As Object)
	posterScreen = preShowPosterScreen("Search", "")
	searchResults=getShowsBySearch(partSearchText)
	showPosterScreenForSearch(posterScreen, searchResults)
End function

Function showPosterScreenForSearch(screen As Object, searchResults As Object) As Integer
    if validateParam(screen, "roPosterScreen", "showPosterScreenForSearch") = false return -1
    if validateParam(searchResults, "roArray", "showPosterScreenForSearch") = false return -1
    'printList(searchResults)
    screen.SetContentList(searchResults)
    screen.Show()
End function

Are you sure getShowsBySearch is returning a valid content list?

Thanks for your reply #belltown.
Yes! I am getting a ‘roArray’ of showList on calling getShowsBySearch(searchtext) method.
I was able to print the showlist using PrintList() utility in the video player example.

Can you post an example of the output you got when you printed the list?

#Belltown,

Looks the there is some issue with my preShowPosterScreen() method.

I tried to isolate the code to display the roPosterScreen and it worked for me.
The following code worked for me. I sincerely appreciate your time and help. Thanks a lot.
I will post once i figure out the actual issue.


port1=CreateObject("roMessagePort")
screen1 = CreateObject("roPosterScreen")
screen1.SetMessagePort(port1)
screen1.showmessage("Retrieving")
screen1.SetListStyle("arced-landscape")
					
searchSuggestions1 = GenerateSearchSuggestions(fullResult, screen)
screen1.SetContentList(searchSuggestions1)
screen1.Show()

I think you might need:

screen1.ClearMessage ()

after the call to SetContentList
