If I understand correctly, the swift button is a custom view.
The ide does not know what a custom view "is", nor what view it mimics... to the idea, the custom view is just a panel.
I would use the tag property of the base panel and use it as a means of getting that type of info.

The tag property of the SwiftButton contains a code "00000..."
Doesn't it matter if the tag is pre-filled with a code?
I am going to try...

Thx @Cableguy

the tag can hold an object, it can even hold an array or even a type

I pre-filled the tag property of all SwiftButtons with a code. I hope that does not matter... but I'm afraid I'm not going to know how to solve it

If you define a type and set it to the tag property, you can add as many fields as you want even with different primitives

Like
Dim swiftbuttontag( code as int, Viewtype as string)
Dim siftbuttontag1 as swiftbuttontag
Swifbuttontag1.initialize(0,"swftbtn1")
Switftbutton1.tag = swiftbutyontag1

This is pseudoscience, not sure of correct syntax

Never use 'Node', only B4XView.

I read it last month.. I was reread right now!! bookmarked in my firefox

The solution is

B4X:

For Each swb As B4XView In MainForm.RootPane.GetAllViewsRecursive
    If swb.Tag Is SwiftButton Then
        Dim kk As SwiftButton = swb.Tag
        Log(kk.Tag)
        '.........Rest of code
    End If
Next

Thx!!

The same principle applies...
But "we" tend to use that tag property in a simplistic way, setting a single value to it... but since it can hold an object, it can do much more, even hold a reference to another view.
