B4J Question B4XTable ScrollOffset, ScrollBarChange Event...

[Magma]

Hi there...

here started.. a little project for resizing b4xtable but have some problems...

1) i can;t get scrolloffsetx... for example:

when trying to get it with this command:

    Dim scrollx As double=B4XTable1.mBase.ScrollViewOffsetX
     Log(scrollx)

getting error:

Call B4XPages.GetManager.LogEvents = True to enable logging B4XPages events.

mBase is "always" the name of the base PANE(L) of a custom view.
You should get the CustomListView using GetView (I don't know which index, probably 0) from mBase. I'll tell you shortly.

EDIT: it is simply B4XTable1.clvData

 

[LucaMs]

Dim clv As CustomListView = B4XTable1.clvData
Log(clv.sv.ScrollViewOffsetX)
