Roku Developer Program

I'm new to Roku development. I'm  trying to customize the ro- listscreen component... 

1. Whether can i swap the image 1 and image 2 positions as shown in the screenshot.
2. Is any chance to customize the pre-defined  components in roku sdk ? like poster screen, list screen etc.... 

 title:            
 ID:           
 HDBackgroundImageUrl: 
SDBackgroundImageUrl: 
SDSmallIconUrl: 
HDSmallIconUrl: 
ShortDescriptionLine2:
ShortDescriptionLine1

3. where to get the predefined variables names for component? 
4.Is it possible to draw the own screen without using components?

Yes, if you use roScreen - https://sdkdocs.roku.com/display/sdkdoc/roScreen[/url:3g0tiuq1].  You will have to build everything ...

@priya_sp - you cannot "swap the images" in roListScreen.

Other than going bonkers with "Roku Scene Graph", your other options in customizing is to use roImageCanvas (which might be good for you) and roScreen (probably not).

how to handle the remote key events if i go for roscreen or roimagecanvas ?

[priya_sp]

is there any way to divide the screen into two equal parts?

The same way like in roListScreen - you run a loop checking for messages from the component and albeit the event type is different, the meaning/handling is the same:

roListScreen: roListScreenEvent, variant isRemoteKeyPressed()
roImageCanvas: roImageCanvasEvent, variant isRemoteKeyPressed()
roScreen: roUniversalControlEvent

I imagine you are thinking something like HTML frames, so that you can put one ro-classic component on one side and another in the other half of the screen. The answer is "no", there is no such feature.

having few doubts

1.

canvasItems = [
        { 
            url:"http://192.168.1.23/boardwalk.jpg"
            TargetRect:{x:100,y:100,w:400,h:300}
        },

whether x,y values in targetrect fit into all screens without problem..does it create problem in smaller screen?

2.i have created a rectangle using canvas..now is it possible to create the listscreen inside the rectangle canvas

3. i have divided the screen by drawing the 2 rectangles using ro-image canvas.Aftr that im trying to use api calls to get the data inside the 1 st rectangle.is it make sense ??

Requirements
1. need the customized screen --where i want to call api's and to render the data.if i go for ro-image canvas option( which is used to render only text and image).i was not able to call the api's..which component i should use to render the api's data as well as should customize the UI screen completely
