[FMX] Depth

I try to obtain the effect like this:
It’s the effect in the 1ST page, after you click on enter, where you have 3 schedules that change depth.
My problem is that when i use the swapDepth, in the same moment I click on the second schedule (For exemple), the depth change.
I would like the depth change after the animation and not imediatley.
So, excuse me for my english, I hope you understand what I mean!!
Bye bye!!
