Android Question B4XPage and Public Variables

[Sabotto]

I apologize in advance if what I'm about to ask may be trivial

I have three doubts regarding the B4XPages and Public variables:
1) How do I call a Public variable in a B4XPage from another B4XPage?
2) If that variable must be visible from two pages, in which of them is it better to declare it? Is indifferent? (Obviously excluding a specific Module)
3) In Sub Initialize, what goes?

'In B4XMainPage'
Sub Class_Globals
    Private Root As B4XView
    Private xui As XUI
    Public MyVar as Int ' Do I declare it here? Or in B4XPage2?
End Sub

Public Sub Initialize
'What goes here?
End Sub

'In B4XPage2
Log(B4XMainPage.MyVar) ' Error!!! How should I write?

These are classes, not static code modules => you need to hold a reference to a specific instance.
There are all kinds of ways to do it. For example:

Log(B4XPages.MainPage.MyVar)
Dim mp As B4XMainPage = B4XPages.GetPage("MainPage")
log(mp.MyVar)

Thanks erel. And question 2 and 3?

 

[Erel]

2) Both options are good.
3) All classes have an initialize sub. It runs before B4XPage_Created event is raised. You can leave it empty or you can put code in there that will run before the page is created.

Of course, being a class I can initialize it with parameters. I miss this concept. Thank you
