Scrollview and collide_widget

[caracteriel]

Hi,

  I would like to make "collide_widget" worked with widget in scrollview and widget out scrollview.

At the moment I get always "True"

exemple : 

A=Widget() (any widget)

scroll=scrollview()

scroll.add_widget(A)

B= Widget()

A.collide_widget(B) is always True.

Why ?

I have tried to work with Id, but I still have True……

 I have also tried to get absolute coordinate of my widget (A.pos) in scrollview to send them "in real time" to a "fake" scrollview (I want to have the scrollview motion)

But It seems the widget in scrollview are fixed…

Any idea please ?
