Android Question Make Preferences Dialog Modal

[Cosmo]

Hello all,
didn't find a solution here for this:

Is it possible to make a Preferences Dialog modal, so the program stopps while the user puts in data, and returns to the code after Ok or Cancel is pressed?

How would this be implemented?

Thanks in advance!

Regards,
Bernhard

Thanks for reading this,
after browsing the documentation I found for me following solution.

 ...
    OpenConfiguration
    Wait For OpenConfiguration_Complete
 ...
   
   
Sub OpenConfiguration
    pfdialog.LoadFromJson(File.ReadString(File.DirAssets,"prefs.json"))
    Wait For (pfdialog.ShowDialog(PrefData, "OK", "CANCEL")) Complete (Result As Int)
    If Result = xui.DialogResponse_Positive Then
        Dim ser As B4XSerializator
        File.WriteBytes(xui.DefaultFolder,PrefsFile,ser.ConvertObjectToBytes(PrefData))
    End If

    CallSubDelayed(Me, "OpenConfiguration_Complete")
       
End Sub

There is a better way: [B4X] Resumable subs that return values (ResumableSub)

Sub OpenConfiguration As Resumable
 ...
Return True 'you can return a different value if needed
End Sub

Wait For (OpenConfiguration) Complete (unused As Boolean)

Many thanks, I'll try!
