Hi

I thought it was about time to redesign my pronto and get to grips with prontoscript. I have a multiroom setup with 2 rooms. On the room selection page there two buttons, one for the lounge and one for the bedroom, these buttons contain the following script

System.setGlobal("Room","1")
CF.widget("JUMP","RESOURCES").executeActions()

and

System.setGlobal("Room","2")
CF.widget("JUMP","RESOURCES").executeActions()

On the main Activity menu page, I have buttons for watch tv, dvd etc. On this page I would like to know what the room is currently set to. I have a panel which can change it's label according to what value is stored in "Room" but what I want it to do is to display a different image acording to the value of "Room". I have a hidden page called RESOURCES and on that page I have 2 panels each with the image I require. The panels are called LOUNGE and BEDROOM respectively and they are sized the same as the panel on the activity menu page.

Im guessing I need to be using setImage() but the developers guide doesn't cover it much. Can someone point me in the right direction

Thanks
Rich

You are heading in the right direction but please allow me to "steer" you aside a bit.

PDF files are also indeed searchable. In the Version 1.0 developers guide from July, the 2nd hit for "setImage" indicates there's an example for copying an image at the bottom of page 21.

Heres another example on copying images.

var wTarget = CF.widget('TARGET','MAINPAGE', 'HOMEACTIVITY');
var wResource = CF.widget('LIVING_ROOM',RESOURCES','MY_RESOURCES');

// copy the first image (index 0).
wTarget.setImage(wResource.getImage(0),0);

To maintain state, you will need to use System.setGlobal() and System.getGlobal().

To elaborate, panels have one image and buttons have two. Think of the images as held in an array refrenced by indicies 0 and 1, Perhaps someday Philips will allow this array to be expandable and to hold many images for animation

The getImage method of a widget takes as an argument the index into the image array of that widget and returns a structure suitable to be used by the setImage method

The setImage method takes two arguments, the first being exactly that returned by the getImage method and the secondf the index into the widgets array of images where the gotten image is to be placed.

As Lyndel nicely shows most of us just use the getImage method on the source of the image as the first argument of setImage.

I am not sure if you can store the result of a getImage method in a prontoscript variable, but it would be nice if you could... Lyndel? I guess one could just try it out.

Should work just fine although I, too, usually use the inline method of set/get.

Images can indeed be stored as they are just Javascript representations of underlying objects.

Thank you Lyndel. Your example makes far more sense to me then the one in the developers guide that I had already tried. Working perfectly now

Thanks again
Rich
