Hi,

When I display my content in a grid there's a huge gaping hole at the top of the page. I realize this goes away if you scroll down the categories, however is there a way to start with the first category at the top of the page?

Here's a screen shot.

categoryList = ["Comedy Clips",
				"RIFF-erendum Interviews",
				"Auditory Suppository Show",
				"Skits & Sketches"]
    
    showList = getShowsForCategoryItem(categoryList[0])
    podcastList = getShowsForPodcast(categoryList[1])
    assList = getShowsForASS(categoryList[2])
    sketchList = getShowsForSketches(categoryList[3])
	
    screen.setupLists(categoryList.count())
    screen.SetListNames(categoryList)
    screen.SetContentList(0, showList)
    screen.SetContentList(1, podcastList)
    screen.SetContentList(2, assList)
    screen.SetContentList(3, sketchList)
    
    screen.Show()

Also, some of my content is audio only w/o video, in that case I launch an roAudioPlayer from the roSpringboardScreen. The plus side is that the cover art / preview image and description remain on the screen when the audio plays. There are at least 3 downsides to doing this, I don't see how to say "loading please wait" when the user hits play, and some of the audio files are 90-120 minutes long, so there is a slight delay. Without notification/feedback that it's actually doing something it might cause problems. Another issue is stopping playback, it's a pain. It seems like it takes a long time (after pressing button on remote) to decide to stop and go back, so it appears to be stuck playing. One more thing, after playing roAudioPlayer and stopping it, going back to the selection grid.. it's a complete wreck. There's large black areas on the screen and the selection pane is misaligned... check out this screenshot.



Code,

    
    downKey=3
    selectKey=6
    while true
        msg = wait(0, screen.GetMessagePort())
        if type(msg) = "roSpringboardScreenEvent"
		if msg.isButtonPressed()
                    if msg.GetIndex() = 1
			if showObject.format = "mp4"
				showVideo(showObject)
			else
				audio = CreateObject("roAudioPlayer")
				audio.AddContent(showObject)
				audio.SetLoop(false)
				audio.Play()
			endif
                    else if msg.GetIndex() = 2
				audio.Stop()
                         return 1
                    endif
            else
                print "Unknown event: "; msg.GetType(); " msg: "; msg.GetMessage()
            endif
        else 
            print "wrong type.... type=";msg.GetType(); " msg: "; msg.GetMessage()
        endif
    end while

If I use an roVideoScreen to play the audio, it shows progress/loading notification but screen goes black during audio playback. This would be cool if I could show the image during playback but I have had trouble loading an image from a URL and displaying on the screen. Does CreateObject("roBitmap"... work with an image stored at a remote Url? image does not seem to appear on screen for me.

bitmap=CreateObject("roBitmap", "http://www.example.com/image.jpg")
Screen.DrawObject(0,0, bitmap)

Thanks for any pointers/suggestions.

Just set your selected row to 1 (or 2 if the arrays are base 1, I forget off hand), that's how most of the apps work. You can do the same for horizontal spacing.

Hi,

OK thanks, that makes sense, I appreciate your reply.

Hey,

Did you get an answer to the issue regarding loading an image remotely (bitmap=CreateObject("roBitmap", "http://www.example.com/image.jpg")?
I'm running into the same issue.

Thanks

No it does not work that way. You first need to download the image to tmp:/ and then createobject("roBitmap","tmp:/myimage.jpg")

Make sure when you save the image, you save it with the correct file extension.

Weirdness with zoom-to-fill?

I noticed that the vertical-aspect layout looks much better, without the empty spot at the top.





Anyhow I get some weirdness with zoom-to-fill. The the roku device automagically update firmware or maybe i'm using png images and the machine doesn't like them for some reason. I actually plan on doing this the 'correct way' and cropping the images properly 🙂 luckily i already have horizontal hints to frame bodies, yay. So I probably won't actually need the zoom-to-fill, wondering if this is a bug?

It is a bug, and it's been around for a long time. zoom-to-fill only works on certain grid styles, though I don't recall which off the top of my head.

Thanks, for all the replies, i totally appreciate the help.

The vertical poster images look _way_ better IMHO,

regarding the post about setting the focused item I see
Void SetFocusedListItem(Integer listIndex, Integer itemIndex)

But i don't seem to find reference to setting the grid spacing.. I think I'm probably OK on default spacing with the vertical poster though.

And I now see the tmp image download example in roAudioMetaDate --
http://sdkdocs.roku.com/display/RokuSDK ... ioMetadata

One question, there's a section in the design guide of the manual that describes an audio screen
http://sdkdocs.roku.com/display/RokuSDK ... yingScreen
it says 'see details screen'.. it's talking about http://sdkdocs.roku.com/display/RokuSDK ... oardScreen correct? or maybe i'm missing it.
thanks



making progress, still need to fix the logo.
