frankhdz I am trying to change the grey color in the overlay in the alert box but I cannot find where this is set anyone know where and if this can be changed?
joshtynjala Customizing the overlay behind the Alert involves setting a custom PopUpManager.popUpManagerFactory. Your custom function could return a new DefaultPopUpManager with a custom overlayFactory. Something like this: PopUpManager.popUpManagerFactory = () -> { var manager = new DefaultPopUpManager(); manager.overlayFactory = () => { // create and return an overlay here }; return manager; };
