Hello anth12

Without testing I don't think there is a way to get the 'touch' point from a GUI element

The way I get around this in my mobile layout designer is to have a transparent panel over the top of the GUI elements. When I touch the display I have call a function to find the view under the X,Y point. Then its a matter of tracking the movement

Example -> Designer example (YouTube video)

The Panel touch sub functions like this:

B4X:

Sub Panel_Touch (Action As Int, X As Float, Y As Float)
   Select Action
      Case Activity.ACTION_DOWN ' user just touched the panel
      Case Activity.ACTION_MOVE ' user moving finger in panel
      Case Activity.ACTION_UP ' user released finger off panel
   End Select
End Sub
