Android Question B4XPages - directly call public methods

[Robert Valentino]

Points 5, 6 & 7 of this post: https://www.b4x.com/android/forum/threads/b4x-b4xpages-what-exactly-does-it-solve.119078/

We can directly call public methods of other pages. No need to use CallSub or CallSubDelayed.
We can directly access public global variables of other pages.
We can directly access and manipulate views of other pages.

I know I am a bad searcher (probably being 70 and mind going to mush), but I cannot find any examples of this.

if I use

B4XPages.

I don't see any of the public's in B4XMainPage and if I try and use

B4XMainPage.

isn't allowed

Confused on how to see the public variables in B4XMainPage and how to call methods without using CallSub or CallSubDelayed.

Thanks

Thanks so much

Just tried this in one of my pages and B4XPages seems to be null

I can use B4XPages.MainPage. to get to any variable or class. But when the code actually runs B4XPages appears to be null

What is the problem? The code Luca wrote is correct.

If you need to access other pages:

Dim p2 As SomeOtherPage = B4XPages.GetPage("page 2")
p2.AnyPublicMemberOfSomeOtherPage(1, 2, 3)

If you need to access other pages:

At the moment I did not want to "complicate" the (simple) things

But when the code actually runs B4XPages appears to be null

Note that B4XPages is never Null, since it is a code module.

Was getting null.

Let me see if I can create a test program.
