B4J Question ScrollPane1 B4j

[SMOOTSARA]

Hello friends
I need to build a ScrollPane1 and load a latout in it.(ScrollPane1)


I make it in Designer.
And I created another layout in the designer for add to ScrollPane1 .(layout_data)

But when I define the layer

Sub Class_Globals
Private ScrollPane1 As B4XView
End Sub

Private Sub B4XPage_Created (Root1 As B4XView)
    
    Root = Root1
    Root.LoadLayout("MainPage")
    B4XPages.GetManager.SetTitle(Me,"test name)
    
    

    Log(ScrollPane1.IsInitialized)   
    ScrollPane1.LoadLayout("layout_data")

End Sub

I get the following error

Waiting for debugger to connect...
Program started.

[Erel]

It should be ScrollPane1.ScrollViewInnerPanel.LoadLayout(...)

 

[klaus]

ScrollPane1.ScrollViewInnerPanel.LoadLayout(...)

Strange.
The ScrollPane1.LoadLayout method does exist.
The ScrollPane1.ScrollViewInnerPanel does not exist !?
The ScrollPane1.InnerNode does exist but it has no LoadLayout method.

Then:
ScrollPane1.LoadLayout (LayoutFile As String, Width As Double, Height As Double)
needs three parameters!

Klaus,

Smootsara has defined the Scrollpane1 as a B4xView which has the inner pane exposed as ScrollViewInnerPanel.
