EDIT (bumped up Dec 17th): are really there no AHK nerds able to answer to this? (even "no it aint possible!! stop whining around and bothering the forum!!" would do it..)

------------------

I've got 3 ListViews in a GUI.
How do I know (other than intrinsically knowing it because I set in in my code; "Gui, ListView, MyListView3" whereas MyListView1 and MyListView2 exist as well on the same GUI) from a common subroutine or function, for instance, which one is the current "default" ListView upon which to operate?
Note: in this script the caller cannot pass this info.

EDIT: I'm adding my latest msg here so whomever opens this thread for the 1st time hasn't got to read throughout all of it (and hopefully dont get it wrong...):

AHK Official Documentation wrote:
Built-in Functions for ListViews
All of the ListView functions operate upon the current thread's default GUI window (which can be changed via Gui, 2:Default). If the default window does not exist or has no ListView controls, all functions return zero to indicate the problem.

If the window has more than one ListView control, by default the functions operate upon the one most recently added. To change this, specify Gui, ListView, ListViewName, where ListViewName is the name of the ListView's associated variable or its ClassNN as shown by Window Spy. Once changed, all existing and future threads will use the indicated ListView.

Now: to do this AHK must keep the default-listview track somewhere... so the dry question is: is that place accessible, to read its contents at least?

ControlGetFocus can tell you which control has focus
and ControlFocus can be used to set focus of a control

doesnt help...
Code:
Gui, Add, ListView, vMyListView1
Gui, Add, ListView, vMyListView2
Gui, Add, ListView, vMyListView3
Gui, Add, Button, SomeAction
Gui, Show
......................
......................
ButtonSomeAction:
AddItem()     ; here the focus is on the button...
return           ; but I can think of plenty of other situations...


but above all wooly_sammoth: the default listview is set by the code and not by the user actions over a GUI... which means that even though MyListViewN has the focus, it's not necessarily the default ListView for the code's actions
