In MAIN

Sub Globals
                  
         Private dbtable As Table
        Private dipilih As PilihRT
   
End Sub

Sub Activity_Create(FirstTime As Boolean)
    dbtable.Initialize(Me,"dbtable",5)
    dbtable.AddToActivity(Activity,0,0dip,100%x,80%y)
    dbtable.HeaderColor=Colors.Blue
    dbtable.HeaderFontColor=Colors.White
    dbtable.SetHeader(Array As String("Loker","Customer","Room","Terapis","Waktu"))
   
    dipilih.Initialize
   
End Sub

Sub dbtable_CellClick(Col As Int, Row As Int)
    dipilih.Show
End Sub

in CLASS PilihRT

Sub Class_Globals
    Private Room As Spinner
    Private Terapis As Spinner
    Private BtnWaktu As Button
    Private BtnCancel As Button
    Private BtnOK As Button
    Private Panel1 As Panel

Did you get any ERROR? Which error?
Post as much Information as possible.

panel1 is not initialized.

I don't see it initialized and added to something by code or loaded via a loadlayout.

panel1 is not initialized.

I don't see it initialized and added to something by code or loaded via a loadlayout.

I add this :

Public Sub Show
    Log("load PilihTerapis Layout")
    Panel1.Initialize("Panel1")
    Panel1.LoadLayout("PilihTerapis")
    Panel1.SetVisibleAnimated(500,True)
End Sub

But it not show
and in Logs is

Panel size is unknown. Layout may not be loaded correctly.

 

[DonManfred]

Add the panel to a activity first.

Activity.AddView(pnl,x,y,w,h)
pnl.loadlayout("layout")

I suggest to read and understand these guides...

• Beginner's Guide (pdf)

• User's Guide (pdf)

I think that you need to explain more in detail what exactly you want to do.
Do you really need a Class?
If yes, do you want a Standard Class or a CustomView?
For CustomViews you may read the B4x CustomViews booklet which includes examples, link in my signature.
You could use a Panel and show or hide it without a Class.
But without knowing the details it's difficult to give you a concrete advice.
