Hi all,

I'm having trouble changing the style of the roGridScreen (using SetGridStyle()) to anything other than the default (flat-movie). Is anyone else having this problem?

Can you elaborate on the kind of trouble you're having? I've used virtually every different grid style across my channels, so they definitely work. Perhaps you could post the code you're using as well...?

That's good, I must be doing something wrong then. I'm just running some basic code to see what layout I want to use. It's pretty close to the example in the Component Reference document. If you see what I'm doing wrong, I'd love to hear what it is.

This is the function I'm using to set up the roGridScreen:

Function ShowGrid()

    port = CreateObject("roMessagePort")
    grid = CreateObject("roGridScreen")
    grid.SetMessagePort(port)
    
    rowTitles = CreateObject("roArray", 10, true)
    for j = 0 to 4
        rowTitles.Push("[Row Title "+j.toStr()+" ] ")
    end for
    grid.SetupLists(rowTitles.Count())
    grid.SetListNames(rowTitles)
    grid.SetGridStyle("flat-16x9")
    grid.SetDescriptionVisible(false)
    
    
    for j = 0 to 4
        list = CreateObject("roArray", 10, true)
        for i = 0 to 2
            o = CreateObject("roAssociativeArray")
            o.ContentType = "episode"
            o.Title = "[Title"+i.toStr()+"]"
            o.ShortDescriptionLine1 = "[ShortDescriptionLine1]"
            o.ShortDescriptionLine2 = "[ShortDescriptionLine2]"
            o.Description = "[Description]"
            o.Description = "[Description2]"
            o.Rating = "NR"
            o.StarRating = "75"
            o.ReleaseDate = "03/25/2011"
            o.Length = 196
            o.Actors = []
            o.Actors.Push("[Actor1]")
            o.Actors.Push("[Actor2]")
            o.Actors.Push("[Actor3]")
            o.Director = "[Director]"
            o.SDPosterUrl = "[poster url]"
            o.HDPosterUrl = "[poster url]"
            
            list.Push(o)
        end for
        grid.SetContentList(j, list)
    end for
    
    grid.Show()
    
    while true
    msg = wait(0, port)
        if type(msg) = "roGridScreenEvent" then
            if msg.isScreenClosed()
                return -1
            elseif msg.isListItemFocused()
                print "Focused msg: ";msg.GetMessage(),"row: ";msg.GetIndex(),
                print " col: ";msg.GetData()
            elseif msg.isListItemSelected()
                print "Selected msg: ";msg.GetMessage(),"row: ";msg.GetIndex(),
                print " col: ";msg.GetData()
                grid.ShowMessage("You selected Row "+Stri(msg.GetIndex())+" Column "+Stri(msg.GetData()))
            endif
        endif
    end while
End Function

Thanks for your time,

It looks like you need to set the grid style prior to calling SetupLists(). Move SetGridStyle() to just before SetupLists() and you should be good to go.

Ah, thank you! That was it. It's working perfectly now. I should have thought of that. Thanks for your help.
