Share My Creation Creating javafx buttons with images

Hi, 'b4jers'
B4j can easily import and encompass the javafx controls and deals with them as native controls. As a demo of this power of b4j
I present this outcome of a small app that took a considerable deal of research, trials and errors, and code organization..
It displays three buttons imported from javafx, two of them are with images.. their events were brought to b4j and used to show
an open file dialog and a save file dialog also imported from javafx by the same way of getting the buttons.
Have a nice day..

Actually I was thinking about a button image / button icon for my b4j app some time ago. This should be handy.

 Dim btn as JavaObject

Dim imgPath As String =File.Combine(File.DirApp,"home32.png")
btn=(Me).As(JavaObject).RunMethod("createButtonWithImage",Array("Home",imgPath))
(Me).As(JavaObject).RunMethod("addListener",Array(btn))
Form1.RootPane.AddNode(btn,60,30,0,0)
Private Sub btn_click(msg As String, caption As String)
    Log($"Button with text  '${caption}'  was clicked"$)
End Sub
