Android Question B4XPages, Private / Public B4XPages variable, what's the different?

[incendio]

Hi guys,

Ran this example

[B4X] B4XPages - Cross platform and simple framework for managing multiple pages

B4XPages is a library that serves two purposes: 1. Make it simple to develop B4A apps by solving almost all of the challenges involved with Android complex activities life cycle. B4XPages makes B4A behave more similar to B4J and B4i where the new "B4XPage" element is a regular object that is...

b4x.com

There are codes on B4XMainPage

Sub Class_Globals
    Private Root As B4XView 'ignore
    Private xui As XUI 'ignore
    Public txtUser As B4XFloatTextField
    Private btnLogin As B4XView
    Public Page2 As B4XPage2
    Public Page3 As B4XPage3
End Sub

Variables Page2 & Page3, why they are need to be public?

I think public or private doesn't matter in this case, cause with the new method B4XPages.GetPage(Id), Page2/Page3 can be accessed from any sub or class. RIght?

There are several ways to access the pages instances.
Using B4XPages.GetPage is good and using B4XPages.MainPage.Page2 is also good.

 

[incendio]

Kind of redundant, don't you think?

I will use the old method then, B4XPages.MainPage.Page2.

 

[Erel]

No. B4XPages are regular classes. You can access them however you like.
There is no reason not to provide B4XPages.GetPage method as it can be convenient. If you don't need it then don't use it.

I just feel strange about this method : B4XPages.GetPage.

If there is other way to get the same result, why should create other method, but, you are the creator, you can do whatever you want.

 

[Erel]

Who said that we want to add the pages variables to the main page at all? There are many ways that the pages can be created.
Maybe we want to access 'page 9' from 'page 8'. Why should page 9 be declared in main page for this? Better design to get page 9 using GetPage.

I'll stop here.

Don't get wrong. I didn't mean to judge you.

I really appreciate your work here to keep upgrade B4X products even it is free.

Don't get wrong. I didn't mean to judge you.

I didn't get you wrong. Don't worry.
