using transform with hover?

[jack_norton]

I thought about a nice effect to have on buttons using the new screen and ATL. What I wanted to make is quite simple: I have some buttons and wanted to zoom them in/out as the player hover the mouse over them.
However, I am not sure really how I could do this - I mean the imagebutton should call an action on the over? but that action can modify the transform of the imagebutton that called it?
I am a bit confused before ATL I managed to make some effect like moving buttons using classes, like for a RPG where staves would go up/down when hovering mouse on them:

Code: Select all

        class Staff(object):
            def __init__(self,id,x,y):
                self.x=x;self.y=y;self.id=id;self.ok=None
            def show(self):
                self.ok = True
                renpy.store.curid=self.id;renpy.store.tipT=Eld[self.id]
                renpy.sound.play("snd/e"+str(self.id+1)+".ogg")
                renpy.show("staff"+str(self.id), [FactorZoom(.7, .75, 0.6, opaque=False),Position(xalign=self.x,yalign=self.y)])
                renpy.restart_interaction()
            def hide(self):
                if self.ok:
                    renpy.show("staff"+str(self.id), [FactorZoom(.75, .7, 0.6, opaque=False),Position(xalign=self.x,yalign=self.y)])
                    renpy.store.curid=-1
                    self.ok = False
                    renpy.restart_interaction()

but I must admit that I wouldn't know how to reproduce that for example using the new screen/ATL system. If anyone can illuminate me (and maybe others) with an example would be welcome

If you put a button directly inside a transform, the various button-related events (on hover, on idle, on selected_hover, on selected_idle) will be delivered automatically.

Ahhh me=stupid. I didn't notice you added (or maybe there were already) the various events on the ATL thanks!

I still don't quite understand the specifics of this - how does one put an imagebutton inside a transform and then add it to a vbox or hbox? This could greatly assist me in the creation of my buttons.
