B4J Question Reading Mouse Position

[TheSirOwl]

My daughter is learning to program in Java and just wrote a program for eyes to follow the mouse position. I would like to try the same thing here in B4J. How do I read the pointer position when it is in a UI or Panel

Example for a panel named anchor :

Sub anchor_MouseMoved (EventData As MouseEvent)
Log(EventData.X & " " & EventData.Y)   
End Sub

Hello,
It seems it doesn't work when the panel is transparent
It works when I remove these lines :
MainForm.SetFormStyle("TRANSPARENT")
MainForm.BackColor = fx.Colors.Transparent

May be I'm wrong but I think it may be possible to get the absolute mouse position from the screen and not from an object

Thank you Erel,
I copy here the part of code which is particularly concerned :

  Dim jo As JavaObject = EventData
  Mouse_x = jo.RunMethod("getScreenX", Null) 
  Mouse_y = jo.RunMethod("getScreenY", Null)
