I need multipage layout, so I have a look into B4XPages. What I cannot grasp is how I create many pages in Designer? If I have create each and every label and button programmatically would it be by far easier to make them visible or not visible? Thanks Serg

Hello everyone! I'm building an android app with B4X and I want to create a Log Out Button on every screen. The way I thought of it to work is this: Call the LogIn page (B4XPages.ShowPage("MainPage")) The page that the user was on disappears. the B4XPage_Disappear() Sub is called. In that...

In a B4XPages project I am downloading map tiles in a Sub in a non-B4XPage class (clsMapTileManager). This can be a long process, so I am trying to keep it going with PhoneWakeState and PartialLock. This works for a while, but eventually the process is interrupted by the OS and that triggers in...

I understand that this returns an ordered B4XSet with the current stack of pages, but I wonder what exactly "current stack of pages" means. If a page is closed by pressing the Android < button then that page doesn't show in the above list, but it must exist in some form as I don't have to load...

Just started with B4XPages and added a simple custom menubar, not based on the built-in Android menubar, but based on layouts with panels, labels and buttons. As far as I understand most apps will access the built-in menubar in some form, but I may have this wrong. In my old, non-B4xPages app...

Hello, This is a wish. When B4Xpages has become the universal way of programming, it became more difficult for me to use the examples in the forum, as they as sometimes based on the original b4j UI. I would like to learn more about how B4Xpages works "under the hood", to have a better...

Is it possible to display the pages without the title bar?
