End Sub

Sub AppStart (Form1 As Form, Args() As String)
    MainForm = Form1
    MainForm.RootPane.LoadLayout("Layout1")
    MainForm.SetFormStyle ("TRANSPARENT")
    MainForm.BackColor = fx.Colors.Transparent
    MainForm.Show
End Sub

Sub Button1_Click
    MainForm.Close
End Sub

Private Sub MainForm_MousePressed (EventData As MouseEvent)

Which desktop manager you are using? Gnome, KDE Plasma, XFCE?

Think there's a lack of information here, is it a virtual machine running in a window?

The java window (running in Linux) can only exist in that virtual machine window, it can't escape onto the host OS desktop, VM doesn't know it exists.
