Opaque background with gradient

Using fillAphas with fillColors we can create attractive opaque gradient backgrounds backgrounds in Flex.

While I am still in the middle of my googling for the precise documentation of fillAlphas property, I could have learn that fillAlphas perpery is an array of two numeric elements between 0 and 1 which indicates opacity of the two parts of the correspoding Flex component . fillAlphas works hand-to-hand with fillColors as if there is no gradient, we do not need to adjust the opacity of different parts of the component.

Here is an example:

 
  Canvas
  {
   fillAlphas: 1, 1; 
   fillColors:  #FFFFFF,#D00808;  
   borderStyle: applicationControlBar;    
  } 
 
 
  

and here's how it looks like-
