B4J Question rasperry and jFxExtraGauges

[Hagen Schloemer]

Hello!

is ist possible to user a rasperry and jfxextragauges? my little test-project includes a snipped from the demo project, but the rasperry shows "Parent event already exists".

LCD.Initialize("LCD")
MainForm.RootPane.AddNode(LCD, 160, 250, 250, 75)
LCD.LcdMaxMeasuredValueVisible = True
LCD.LcdMinMeasuredValueVisible = True
LCD.BargraphVisible = True
LCD.ValueAnimationEnabled = False

thanks in advance

Can you post the full error message from the logs (use B4J-Bridge to connect to the board)?

Hi Erel!

I have started in a terminal session, ( i know that cannot be functional, but the error-message is the same....;-)

main._appstart (java line: 57)
java.lang.IllegalArgumentException: EventType "javafx.event.EventType@12dd5f2"with parent "EVENT" already exists

Where is the b4j-bridge? i know only the the b4a bridge from android devices....

best regards

My guess is that there is a missing API. If you can post the full error message from the logs then it will be helpful.

The very simple Test-Program is here:

Sub Process_Globals
Private fx As JFX
Private MainForm As Form
Private LCD As JFXtrasLCD
End Sub

Sub AppStart (Form1 As Form, Args() As String)
MainForm = Form1
MainForm.RootPane.LoadLayout("Layout2") 'Load the layout file.
LCD.Initialize("LCD")
MainForm.RootPane.AddNode(LCD, 160, 250, 250, 75)
LCD.LcdDesign = "RED"
LCD.LcdMaxMeasuredValueVisible = True
LCD.LcdMinMeasuredValueVisible = True
LCD.BargraphVisible = True
LCD.ValueAnimationEnabled = False

MainForm.Show
End Sub
