I have a List in a mobile project for which I want half of the List to be transparent. So what I did is set the "contentBackgroundAlpha" MXML value to 0 in teh <s:List> element, and in a custom ItemRenderer I set half of the List item to have a colored background.
But when I run the application, the one half that should be transparent is "white". The other half displays the color that I set correctly.
So I do not understand why am I seeing a "white" background instead of a transparent background.
I could handle it to make the hole project tranparent with the help of this tutorial:
I don't know if it is possible to make only single components transparent...but I don't think so..
wish you good luck
