B4J Question TagPane closing tabs and/or check for existing tab

[Lahksman]

Basicly 2 small questions:

• How can you close a tab previously created?
• How can I check when a user tries to open a new tab, if this tab already exists?
  For example, the user already opened a product tableview but this tab is not active and he tries to open it again. How can I jump to the already opened tab.

Are these 2 things possible or is there any other library I can use. Haven't found one yet.

How are you closing the tabs? TabPane disables the closing feature.

I'm not closing them. I was looking for a way to close them.
But guessing from your reply it's not possible.

You can use this code to allow the user to close tabs and find the tab that was closed:

Sub Process_Globals
   Private fx As JFX
   Private MainForm As Form
   Private TabPane1 As TabPane
End Sub

Sub AppStart (Form1 As Form, Args() As String)
   MainForm = Form1
   MainForm.RootPane.LoadLayout("1")
   MainForm.Show
   TabPane1.LoadLayout("2", "Tab 1")
   TabPane1.LoadLayout("2", "Tab 2")
   Dim jo As JavaObject = TabPane1
   jo.RunMethod("setTabClosingPolicy", Array("ALL_TABS"))
   Dim ev As Object = jo.CreateEventFromUI("javafx.collections.ListChangeListener", "TabsListChanged", Null)
   jo.RunMethodJO("getTabs", Null).RunMethod("addListener", Array(ev))
End Sub

Sub TabsListChanged_Event (MethodName As String, Args() As Object) As Object
   Dim jo As JavaObject = Args(0)
   jo.RunMethod("next", Null)
   Dim removed As List = jo.RunMethod("getRemoved", Null)
   Dim tp As TabPage = removed.Get(0)
   Log($"Tab: ${tp.Text} removed."$)
   Return Null
End Sub

Works like a charm.
