There is an update to EPG data loading, but I think that is the extent of improvements to the EPG in this release. I was referring to this forum by the term "BB" as in Bulletin Board.

Is there a way for a video node to change the color of the loading progress ? Is it possible to change the color of the cursor when using for example a rowList component ?

[sudo97]

On system v7.0 I could Observe few fields, Load data from memory, server, etc. and then unobserve it and modify without any callbacks. Then I updated to 7.1 and after calling obj.unobserveField("field") -- I got nothing, It doesn't work. Tested on Roku 3 and Roku Stick.

I load settings from registry, and then modify to save it:

sub init()
 m.Settings.action = "read"
 m.Settings.ObserveField("value", "SettingsLoaded")
 m.Settings.control = "RUN"
end sub

sub SettingsLoaded()
 m.value = m.Settings.value
 m.Settings.unobserveField("value")
...
end sub

sub ChangeSettings()
 m.Settings.action = "write"
 m.Settings.value = m.value REM this calls SettingsLoaded, even when field is unobserved.
 m.Settings.control = "RUN"
end sub

I am looking for suggestions on how to overcome some of the limitation on the Scene Graph SDK, and would appreciate if anybody has any tips on the following:

1 - It seems that is not possible to subclass a component. If you have a base set of functions, for example, to manage UI element focus, It is a bit counter productive to have to copy and paste the same code in each component. Is there any way to circumvent this ?

2 - It seems that the only way to communicate in an out of components is trough interfaces, which work a lot like 'properties' in an OOP structure. I see though that 'methods' are not supported. Is there a way to get around this?

3- Last but not least, why is it not possible to specify something like a roArray as a valid interface type? the doucumentation seems to suggest that only a few narrow types of very specific array are allowed (2DFloat etc...) , but not just an array of Object for example. The only workaround i have found is to put the array inside an assocarray and it just seems like strange limitation...

Thanks

You could put the utility code in a separate file and use the "uri" attribute of the <script> element instead of copying and pasting the code.

Is it possible to hide the "Retrieving" (loading) text when using the Video node? When using the Video node in a picture-in-picture mode, the loading text is rendered on top of my UI.

Hi

I found some defects in Scene Graph Components.
1. In ScrollableText after scroll down and changing text scroll is not moving to position 0. Text is still scrolled. I know I can recreate this node to solve that. I'm not sure what have better perfomance.
2. When RowList is using component instead simple then focus is showing to element with index 1 instead of 0. Setting focusXOffset is fixing that

I also have some suggestions in components that I miss a lot:
1. Poster have sometimes problem with loading images. Especially after screensaver is hiding. No message is showing can be read, only state.
2. In ScrollableText I miss functionality to scroll text from code. It is required when we have list in bottom of ScrollableText and we want switch focus using Up/Down keys.
3. We can't turn off handling keys for Roku predefined nodes . It changes sometimes our vision of controling app, or prevents some features
4. We can't provide to ObserveField function a flag: alwaysNotify. It can be done only from interfaces.

I home my finding and suggestions will help you with providing new version of SceneGraph.
Could you please write comments about my suggestions or provide a way to workaround them?

It would be helpful if ifSGNodeChildren had a clear method. Because it doesn't, I've been implementing code like this in certain situations related to dynamic content and recycled views.

	while m.episodeListings.getChildCount() > 0
		m.episodeListings.removeChildIndex(0)
	end while
