    '----full screen modu oldu---
        Dim mf As JavaObject = MainForm
        mf.GetFieldJO("stage").RunMethod("setFullScreen", Array(True))
   
MainForm.RootPane.LoadLayout("Main_from") 'Load the layout file.
    MainForm.Show
    MainForm.Resizable=False
   
    Dim gvh As GameViewHelper
    gvh.AddKeyListener("GVH",MainForm)
End Sub

Sub GVH_KeyPressed (KeyCode As String) As Boolean
    Log(KeyCode)

End Sub
Sub GVH_KeyReleased (KeyCode As String) As Boolean
   
    Log("--"&KeyCode)
    Return FALSE ' try TRUE, same result

Full screen mode without an exit key:

Dim stage As JavaObject = MainForm
stage = stage.GetFieldJO("stage")
stage.RunMethod("setFullScreenExitHint", Array(""))
Dim nomatch As JavaObject
nomatch = nomatch.InitializeStatic("javafx.scene.input.KeyCombination").GetField("NO_MATCH")
stage.RunMethod("setFullScreenExitKeyCombination", Array(nomatch))
stage.RunMethod("setFullScreen", Array(True))
