I am using B4XPages in my project. There is a TTS module which is supposed to play even when screen is turned off. It plays for a while then pauses and resumes only when screen is unlocked ( probably as long as tts queue is clear) So after a lot of forum search - using a service seems to be the...

I wrote here few minutes ago this post: but it is "hidden", there. So I submit the question here, as poll.

Avevo già tradotto (non del tutto letteralmente) un thread di Erel su questo argomento, ma mi è appena capitato di "doverne" parlare e la traduzione si trova all'interno di un thread, sempre nel forum italiano; apro questo in modo che sia trovabile più facilmente, senza copiare tutto il lungo...

This is only an update to the original example from Erel. I'm starting to create cross-platform apps using B4XPages. It is mainly to B4A and B4J, because I don't use B4i, and I tried to put more views that it's not include in the original example. Any improvements are welcome.

This is a very crude version of the code I'm using in a project to create a jigsaw puzzle. What it basically does is cut square images into jigsaw pieces. It's not very cleaned up, but feel free to use and extend as you want. What you can do with this code: Specify the puzzle row/column...

Hi, I would like to show a custom dialog using B4XDialog when I press on a button (filter button) in B4XPages Toolbar. Someone can help me with an example? Thanks

Salve, ci risiamo ho provato a convertire un piccolo esempio con le B4XPages sperando di riuscirci ma continuava a darmi errori strani che preferisco allegare il file. L'esempio è una variante, estratto dal CardList che è un po' datato ma funziona bene allego link originale Card List. Spero che...
