按钮内的闪光灯按钮

Question

I have a button containing 2 child buttons. I want to be able to keep the mouse over state active, when I rollover a child button. At present it fires mouse out when i rollover a child button, I suspect this is correct, but not what I want to happen.

Any ideas how to get around this?

Answer 1

Change from mouseOver state to normal state in the MouseEvent.ROLL_OUT handler instead of MouseEvent.MOUSE_OUT handler.

The purpose of the rollOut event is to simplify the coding of rollover behaviors for display object containers with children. When the mouse leaves the area of a display object or the area of any of its children to go to an object that is not one of its children, the display object dispatches the rollOut event. This is different behavior than that of the mouseOut event, which is dispatched each time the mouse leaves the area of any child object of the display object container, even if the mouse remains over another child object of the display object container.

Answer 2

You can also add the event on both and use stopImmediatePropagation() to prevent mouse out from firing;
