B4J Question [SOLVED]lanterna

[a.consorti]

Good morning,
regarding the code for writing TUI interfaces already started in a previous post (https://www.b4x.com/android/forum/threads/solved-lanterna.161843/#post-992685)
I'm trying to understand how to call a modal window that accepts the classic "YES" and "No" to understand how to proceed.

I tried adding this sub to the code:

[CODE lang="b4x" title="Code"]Sub ShowMessageDialog(title As String, message As String)
' Inizializza MessageDialogButton staticamente
Dim MessageDialogButton As JavaObject
MessageDialogButton.InitializeStatic("com.googlecode.lanterna.gui2.dialogs.MessageDialogButton")

' Ottiene il pulsante OK staticamente
Dim buttonOK As Object = MessageDialogButton.GetField("OK")

' Inizializza MessageDialog e chiama il metodo showMessageDialog
Dim MessageDialog As JavaObject
MessageDialog.InitializeStatic("com.googlecode.lanterna.gui2.dialogs.MessageDialog")

' Esegui il metodo showMessageDialog con i parametri corretti
MessageDialog.RunMethod("showMessageDialog", Array As Object(gui, title, message, Array As Object(buttonOK)))
End Sub[/CODE]

and then recall it via:

[CODE lang="b4x" title="code2"]ShowMessageDialog("WARNING", "Operazione non rilevata!")[/CODE]

Unfortunately I always get the following response:

Caused by: java.lang.RuntimeException: java.lang.RuntimeException: Method: showMessageDialog not matched.

Can you give me some suggestions?

static MessageDialogButton	showMessageDialog(WindowBasedTextGUI textGUI, String title, String text, MessageDialogButton... buttons)

What is gui in your code. Guess it is not a object of type WindowBasedTextGUI

[CODE lang="b4x" title="Code"]Sub ShowMessageDialog(title As String, message As String)
MessageDialog.RunMethod("showMessageDialog", Array As Object(gui, title, message, Array As Object(buttonOK)))
End Sub[/CODE]

The problem is the Array As Object(buttonOK), you need to pass an array of the correct type using JavaObject InitializeArray.

Sub ShowMessageDialog(title As String, message As String)
    ' Inizializza MessageDialogButton staticamente
    Dim MessageDialogButton As JavaObject
    MessageDialogButton.InitializeStatic("com.googlecode.lanterna.gui2.dialogs.MessageDialogButton")
 
    ' Ottiene il pulsante OK staticamente
    Dim buttonOK As Object = MessageDialogButton.GetField("OK")
 
    ' Inizializza MessageDialog e chiama il metodo showMessageDialog
    Dim MessageDialog As JavaObject
    MessageDialog.InitializeStatic("com.googlecode.lanterna.gui2.dialogs.MessageDialog")
    Dim jo As JavaObject
    ' Esegui il metodo showMessageDialog con i parametri corretti
    MessageDialog.RunMethod("showMessageDialog", Array As Object(gui, title, message, jo.InitializeArray("com.googlecode.lanterna.gui2.dialogs.MessageDialogButton",Array(buttonOK))))
End Sub

Thank you very much. It works!!
