Hi,

The GPS support will be added at the end of March.

Doesn’t seem to want to parse everything in my exif…specifically GPS data.

for example, i have already values for the x and y coordinates, and I want to plot it as green stars. What will be the code? I do only know –>>plot2d(x,y,style=-14) But I don’t know how will I make it as green stars

it’s worth to say that the bit operations (like value >> 1) are meant to work on integers and return s only integes.
So if you try to (3 >> 1) you will get 1 as a result.
Also they do a “awful” (just because it can be unexpected) job at rounding for negative numbers. (-3 >> 1 == 2).
For the same reason using int(-1.5) in place of the floor() method will give you wrong results.

In my opinion, you should be really confident about what kind of data you are working with and what kind of results you need before switching to bit operations.

Comment on Flex item renderers, an expandable list with transitions by Jeremy Savoy

Ok, so I have that part figured out now, and my data is populated … very nice, thank you so much !!

One last question … why does the list scroll many items with one click of the mouse scroll wheel, and can this be easily fixed? If you scroll the mouse wheel just one click, it scrolls probably like 7-10 items, really I just want 1 item to scroll up. I suppose I could try to adapt this code to a datagrid instead of a list, and just have one column using the custom expandable renderer?

This is a very useful tutorial … exactly what I’m looking for. However I’m having an issue, I already have an ArrayCollection that is my list dataprovider, how can I integrate an arraycollection into this example? It may seem simple, but I’m having a hard time with it.

Would I simply pass each item in the arraycollection through SmartRenderData?

for( index = 0; index < myAC.length; index++ ) {

var secondaryAC[index]:SmartRenderData =
new SmartRenderData(”", myAC[index]);
}

Please advise, and again thanks !!!
