B4XPages Events
- B4XPage_Created - Called once when the page is created. This will happen before the page becomes visible or after a call to B4XPages.AddPageAndCreate.
- B4XPage_Appear - Called whenever the page becomes visible.
- B4XPage_Disappear - Called whenever a visible page disappear.
- B4XPage_Background - Called when the app is moved to the background. This event will be raised in all pages that implement this sub, not just the top event. This is a good place to save anything that needs to be save as the process might be killed later. Note that in B4J it is raised when the last page is closed.

- B4XPage_CloseRequest (B4J / B4A) - In B4A it is called when the user clicks on the back key or on the up indicator. In B4J it is called when the user clicks on the close button. See post #4 for more information.

The template can be enhanced to include these events, even if they are commented out. This helps newbies like us with the learning curve. For example, the additional event could be
'called whenever the page becomes visible:
Sub B4XPage_Appear
'End Sub
For example, I am using this method to change the title of the page. Yes one can set the title on BX4Page_Created, with a lot of pages and dynamic titles, that is handier. #NewbieThoughts.
