I have a component that displays thumbnails using an image tag
inside of a repeater. What I would like to do is change the alpha of
the thumbnail when it is clicked to show the full image. A list of
image names is being used as the dataprovider for the repeater in
the component. I can get the name of the image selected but am at a
loss as to how to change the alpha.
Component to view thumbnails
<mx:HBox>
<mx:Repeater id="thisRepeater" dataProvider="{imageList}" >
<mx:Image verticalAlign="bottom" click="displayImage
(event.currentTarget.getRepeaterItem())" rollOut="destroyBigTip()"
rollOver="createBigTip(event.currentTarget.getRepeaterItem())"
id="currentImage" source="{currentImageURL + genusName + '/' +
speciesName + '/tn_' + thisRepeater.currentItem.ImageName}">
</mx:Image>
</mx:Repeater>
</mx:HBox>
In the application file
<mx:Canvas id="viewCanvas" styleName="thumbCanvas"
width="600" height="130" x="231.5" y="11">
<Components:thumbViewerHorizontal id = "thView"
verticalScrollPolicy="off" horizontalScrollPolicy="auto"
ourCustomImageEvent="selectFromThumbnail(event)" height="112"
currentImageURL="{currentImageURL}" imageList="{imageList}"
genusName="{genusName}" speciesName="{speciesName}" x="10"
bottom="7" width="580"/>
</mx:Canvas>
