is still developing flash? In fact, the button components in
flash have only some effects. You have to deal with the corresponding response events where the components are used, that is, the relevant logic (code) is generally not where the button components are defined, but where the components are called.

imagine that this effect is actually just a change in the state of a button before it is pressed, and there is no need to deal with the action after the button is pressed, so this screen is actually a situation in which the mouse is put on a dynamic effect, moved away and restored.
