Raphael,
There are a few things you need for the code to work. Below is how I
recommend changing it.
Your dataGrid's dataProvider is 'produtos', and each object within it
has an 'image' property. I recommend having each of these point
directly to an Image object (as opposed to a String of the image's
source). Something like this:
<mx:Image id="myImage" width="150" height="55">
<mx:source>http://www.google.com/images/logo_sm.gif</mx:source>
</mx:Image>
/* (Then, within some initialization ActionScript method) */
// produto is some object with 'modelo' and 'linha' properties
produto.image = myImage;
produtos.addItem(produto);
Now, your resize effect doesn't need to specify the 'target',
'widthTo', or 'heightTo' properties. The latter two specifications
are what I suspect was your main problem. The effect doesn't happen
more than once because it's trying to be resized FROM width 300 TO
width 300. Example:
<mx:Resize id="expand"/>
Lastly, images do have resize issues, as written about in the Flex
API. So put your image inside a canvas, bounded to the sides, and
resize the canvas. Example:
<mx:Canvas
resizeEffect="expand"
width="{(dgProducts.selectedItem as Image).width}"
height="{(dgProducts.selectedItem as Image).height}"
>
<mx:Image
id="img"
source="{(dgProducts.selectedItem.image as Image).source}"
x="10" y="10"
left="0" right="0" top="0" bottom="0"
/>
</mx:Canvas>
That should be all you need. Hope this helps. If you have more
questions, don't hesistate to ask!
