iOS Question Can multiple buttons launch the same event subroutine

DickD · Jun 16, 2017

I have created a layout with buttons named B1, B2, B3 etc. All of them have the save event name BTest. Each has a different tag.

I have created a subroutine BTest_click. Shouldn't clicking any of these buttons launch that subroutine? They don't. Nothing happens. Can this work?

B4X:

Dim B1, B2, B3 as button
...
Sub BTest_click (tag as string)
log("Button pushed: " & tag)
End sub

You don't need:
Dim B1, B2, B3 As Button

And then:

B4X:

Sub BTest_Click
    Private btn As Button
    btn = Sender
    Log("Button pushed: " & btn.Tag)
End sub

That works. Thanks.
