How do I manually trigger a buttons hover state in Flex?

问题

I need to trigger the hover state of a Flex button programatically, so that it looks like the user is hovering over it. There is a flex page about "Manually dispatching events":

Which would work, but what I'd really like to do is change the style of the button without having to throw an event. How can I do this?

Thanks!

回答1:

Is there any reason this wouldn't work?

button.setStyle('skin', button.getStyle('upSkin'));

回答2:

In Flex 4x it is best to change the skin its self, this will do the trick.

 button.setStyle('skinClass', SkinClass);
