i dont know if i am getting what you are saying, but hopefully this
helps. I created an quick item render with an hbox that stretches the
screen depending if the user maximizes or minimizes the screen. I use
css to create the gradient effect.
e.g.
.inconsistencyHboxArrowTail{
borderStyle: applicationControlBar;
fillColors: #EEEEFF, #807F84;
fillAlphas: 0.7, 0.7;
highlightAlphas: 0, 0;
/*focalPointRatio: 0.75;*/
}
<mx:HBox id="hboxArrowImageTail" width="7" rotation="90"
styleName="inconsistencyHboxArrowTail" y="5"/>
but i can assume that if you create another css style such as the one
below and use a event such as mouse off this would help.
.inconsistencyHboxArrowTailOther{
borderStyle: applicationControlBar;
fillColors: #FFFFFF, #FFFFFF;
fillAlphas: 0.7, 0.7;
highlightAlphas: 0, 0;
/*focalPointRatio: 0.75;*/
}
if you post some of your code maybe i can help more, have a great day.
