Can I realize mouseover effects to change slideshow?

[lrenglish]

For example,my page has 7 buttons and each button has its own slideshow of images. There is also a default image. As the mouse move over a button the default image hides and the relevant slideshow appears, when the mouse leaves the slideshow hides and the default shows.

I rememer in earlier version it can be realized by changing sth like mouseover properties.But I cannot find a mouseover property in 7.5. Can anyone do me a favour to teach me how to realize effects like this?

I've tried to do like this
onenter
SlideShow.SetVisible("SlideShow2", true);
SlideShow.Play("SlideShow2");
onleave
SlideShow.SetVisible("SlideShow2", false);
Am I right?
