How do I use mouseEnter on iOS?

[William de Smet]

Hi there,

On one of my apps I change the background of a row round graphics with:
on mouseEnter
set the backgroundcolor of me to black
end mouseEnter

I want to do the same on iOS but it sliding/moving my finger doesn't give
the same effect.
MouseEnter only colors the first graphic.
Is this even possible? Do I have to use touchStart and touchMove? And how?

Any idea's?

greetings,

William
