B4J Question Function keys

[Didier9]

I am trying to catch function key pressed events.
This would not be related to which particular widget on the screen has focus, anything within the app would do.
I saw a reference to this post:

[Solved] Keyboard events

Hello, I can't figure out how to respond to keyboard events in B4J, a bit like keypressed in B4A. I want my application to respond to {ENTER} or {SHIFT + ENTER} strokes. Thanks [EDIT] Solution in post #6

www.b4x.com

but it is not helpful to me. I cannot figure what what this code is doing
Is there another example of function key events that I missed?

Sub AppStart (Form1 As Form, Args() As String)
    MainForm = Form1
    sm.Initialize(Form1.RootPane)
    MainForm.Show
    MainForm.Title = "Key Listener"
    
    AddKeyPressedListener
    
End Sub


Sub AddKeyPressedListener
    Dim r As Reflector
    r.Target = MainForm.RootPane
    r.AddEventHandler("keypressed", "javafx.scene.input.KeyEvent.KEY_PRESSED")
End Sub


Sub KeyPressed_Event (e As Event)
    
        Dim jo As JavaObject = e
        Dim keycode As String = jo.RunMethod("getCode", Null)

        Log(keycode)

        If keycode = "ESCAPE" Or keycode = "C" Then
        Else If keycode = "Y" Then

        Else If keycode = "N" Then
            
        End If
    
End Sub

Require jReflection

or select the gameviewhelper lib...

Sub AppStart (Form1 As Form, Args() As String)
    Dim gvh As GameViewHelper
    gvh.AddKeyListener("gvh",Form1)
End Sub

Sub gvh_KeyReleased (KeyCode As String) As Boolean
    Select KeyCode
        Case "F1":Log("f1 pressed")
        Case "F2":Log("f2 pressed")
    End Select
End Sub

That was too easy, I will ask a harder question next time...
Thanks alot, both of you!
