B4J Question Callsub problem with parameters

[luki_c]

I would like to call the return function from a separate class using callSub2 Test code:

[CODE lang="b4x" title="class test"]Sub Class_Globals
Private fx As JFX

Private callback As Object
Private timer1 As Timer
Private functname As String
Private x As Int
End Sub

'Initializes the object. You can add parameters to this method if needed.
Public Sub Initialize(mCallback As Object,funct As String , interval As Int)

timer1.Initialize("timer1",interval)
timer1.Enabled = True
callback = mCallback
functname = funct
End Sub

private Sub timer1_Tick

Log("Timer tick")
x = x + 1
CallSub2(callback, functname,x)
End Sub
[/CODE]

B4xMainPage:

Sub Class_Globals
    Private Root As B4XView
    Private xui As XUI
    Private test1 As test
    Private obj As Object
End Sub

Public Sub Initialize
'    B4XPages.GetManager.LogEvents = True

    

End Sub

'This event will be called once, before the page becomes visible.
Private Sub B4XPage_Created (Root1 As B4XView)
    Root = Root1
    Root.LoadLayout("MainPage")
    
    test1.Initialize(Me,callbackFnc(obj),1000)
    
End Sub

'You can see the list of page related events in the B4XPagesManager object. The event name is B4XPage.
 Sub Button1_Click
    'xui.MsgboxAsync("Hello world!", "B4X")
    
    Log("test")
    
End Sub


Sub callbackFnc( test11 As  Object)
    
    'Log(test11)
    
End Sub

Returns an error:

Waiting for debugger to connect...
Program started.
Call B4XPages.GetManager.LogEvents = True to enable logging B4XPages events.

How can I fix it? Sorry if there was already a similar thread, I need a return function with parameters

 

[luki_c]

Ok I guess I wrote the post too quickly, typing the function name as a string fixed the problem. Though interesting that when the return function didn't take parameters I didn't have to do that

    test1.Initialize(Me,"callbackFnc",1000)

 

[luki_c]

Now the compiler gives a warning that callbackFnc is not used ?

 

[Erel]

There is a convention for events. You pass the "event name" and the event itself should be:

   CallSub2(callback, EventName & "_Fnc" ,x)

There will be no warning in this case as subs with underscore in their names are considered event subs.

Thank you @Erel now it has become obvious
