Android Question How to tell which layout is in front when device BACK button is pressed

[HappyDad]

I have many panels each corresponds to one layout (loaded by LoadLayout).
When device BACK button is pressed, I want to close the current panel.
So I am using Activity_KeyPress to handle the BACK button press event.
But how do I tell which layout is in front?
I see in this post:

Back button select case statement

I want to create a select case statement for the back button. I guess my main problem is how to dectect which layout is loaded. So something like this. Select case Backbutton case Layout("Main") loaded Activity.removelayout("Main")...

www.b4x.com

that "Select layout" is used to tell.
I tried but it doesn't work, "layout" is not recognized.

layout (in that example) is a global variable. Every time you load a Layout, set this variable to the name of that Layout
