B4J Question How to get a form programatically?

[Dadaista]

Hi all
I created a form programatically but I don't know how to get it

 

[Erel]

Can you post the relevant code?

 

[Dadaista]

Hi Erel... Sure!!!

 

[Erel]

The form you created is not part of the MainForm layout. Only nodes (controls) are part of the layout.

Have you seen this example: https://www.b4x.com/android/forum/threads/modal-dialogs.34656/

Hi Erel
Yes I saw the example a long time ago, but I can not see how solve my problem. When I push cancel button in my form I need to know the form where cancel button is placed and I do not know how to do that.
I can solve it with a global variable but I did not want that
I will continue investigating...

There are all kinds of possible solutions. The modal dialogs example uses a class to implement the form. You can create multiple instances of this class and you can access the class instance variables. It is clean and powerful.

if you have many forms created programatically and therefore difficult to know where is the user, just create a List of the opened forms and check with a simple IF statement where is the user.

I did not tested the code below, may need some tweaking.

Sub btn_Action
    Dim frm As Form = getForm(Sender)
End Sub

Sub getForm(childOfTheFormToFind As Node) As Form
    For Each frm As Form In listOfForms
        Dim joForm As JavaObject = frm
        Dim joStage As JavaObject = joForm.GetField("stage")
        If joStage = getNodeStage(childOfTheFormToFind) Then
            Return frm
        End If
    Next
   
    Return Null
End Sub

Sub getNodeStage(N As Node) As JavaObject
    If GetType(N.Parent).ToUpperCase = "STAGE" Then
        Return N.parent
    Else
        Return getNodeStage(N.Parent)
    End If
End Sub
