B4J Question [SOLVED] Get last object focused

[micro]

Hi to all
How to use getMostRecentFocusOwner() for get the latest node who received the focus?
Thanks

getMostRecentFocusOwner() is an AWT method on a Window object, assuming you are not using AWT but are using JavaFX (Default in B4j) then you can use getFocusOwner on the Scene:

Sub AppStart (Form1 As Form, Args() As String)
    MainForm = Form1
    MainForm.RootPane.LoadLayout("1") 'Load the layout file.
    MainForm.Show
  
    Sleep(0)
    Dim FormJO As JavaObject = MainForm
    Dim Scene As JavaObject = FormJO.GetField("scene")
    Log(Scene.RunMethod("getFocusOwner",Null))
End Sub

Will return null if there is no focused view. You may not need the Sleep(0) depending on where you call it from.

Thanks, stevel05

Now if i have this output

TextField@76c85[styleClass=text-input text-field]

how i can get the reference of this node? (tag, text ...)

    Dim FormJO As JavaObject = MainForm
    Dim Scene As JavaObject = FormJO.GetField("scene")
    dim selectedNode as node
    Try
         selectedNode = Scene.RunMethod("getFocusOwner",Null)
         Log(selectedNode.Tag) ' all node methods available
     Catch
         Log("no node has focus")
      End Try

To get the text:

Dim SelectedNode As Node = Scene.RunMethod("getFocusOwner",Null)
   
    If SelectedNode Is TextField Then
        Dim TF As TextField = SelectedNode
        Log(TF.Text)
    End If
