Change blur filter in modal TitleWindows

I create several instances of TitleWindow. And added them on s开发者_运维百科tage by PopUpManager.addPopUp( wnd, root, true ); But how to change blur of madal state?

Try applying the following styles on the window :

modalTransparencyBlur
modalTransparency
modalTransparencyColor
modalTransparencyDuration

You can also set them globally :

    <mx:Style>
        global {
            modalTransparencyBlur: 0;
            modalTransparency: 0.8;
            modalTransparencyColor: black;
            modalTransparencyDuration: 500;
        }
    </mx:Style>
