View Name

Rusty · Jul 15, 2013

I would like to be able to pass a view (like a button or edit text) to a subroutine and to be able to determine what the view's "name" is.

B4X:

Dim Button1 as button

SubRoutine(Button1)

Sub SubRoutine(Ctl as view)
     MsgBox("The view's name is:  " & clt.name, "")
End Sub

The above code snippet is hypthetical because the Name property doesn't exist. Is there a way to acquire the view name without putting it into the Tag or other property?
Thanks,
Rusty

So you are expecting SubRoutine to return Button1 as a string?
The problem is that Button1 is not really the name of the view, it is just a reference. We could call it ButtonRose = Button1, and both variables will refer to the same view.

Yes, that is what I was hoping for.
I'd like to know the name of the view, if that were possible.
So the Sub routine would show "ButtonRose" in your example.
Ideally, I'd like to know which Activity (layout) the button resides and the button's (text) name.
Thanks,
Rusty

Objects do not have names. One variable can point to many views (not at the same time) and there could be many views without any variable.

For example:

B4X:

Sub CreateButton As Button
 Dim b As Button
 b.Initialize(...)
 Return b
End Sub

You can use a Map to map strings and views.

Thanks Erel. I guess I'll have to use strings to accomplish my task.
