Hi all, I`m trying to add button array (in code) to a panel in a SD_XUIScrollView2D, if I don`t 'LoadLayout' the panel, I can't add the buttons. But the panel is scrollable, if I 'LoadLayout' i can then add the buttons, etc but it doesn't scroll.

Would appreciate pointers to what I`m missing here? I have attached my sample app.

Thanks,
James

Thank you StarDust

If you want to scroll you have to change the size of the sliding panel inside the scrollView.
B4X: 
XUIScrollView1.PanelHeight=NewHeight
XUIScrollView1.PanelWidth=NewWidth
You add the hall_layout panel inside the scrollView by loading it with LoadLayout, but you don't change the size of the scrollView's internal panel.
Also it is not necessary to load a panel with the LoadLayout, I did not understand what happens to you if you add buttons with AddView instead

Thanks, ur demo works as is. But i cant add the buttons to the panel (from code), cos it says panel is not initilised (if i dont't load the layout).

Or maybe i ask a simpler question, in the example how to i add buttons from code to the scrolling panel?

I removed the LoadLayout and inserted panels, no problem


B4X: 
''xScrollView1.LoadLayout("layout2")
      
    For i= 1 To 10
        Dim P As B4XView = xui.CreatePanel("")
        P.Color=xui.Color_Red
   
        xScrollView1.AddView(P,i*35dip,10dip,30dip,30dip)
    Next
