B4X Programming Forum

Hi everyone, After too many long power cuts, I apparently had the questionable idea of writing a small declarative UI wrapper for B4A. DeclarativeUI is an experiment inspired by Flutter and other modern UI frameworks. It lets you describe a screen as a tree of widgets instead of creating and positioning every native view manually. For example:: Dim body As UIColumn body.Initialize _ .Spacing(12dip) _ .AddChild(title) _ .AddChild(description) _ .AddChild(actionButton) The library currently includes state binding, natural layout, themes, navigation inside one Activity, dialogs, snackbars, animations and native view interoperability. It is not intended to replace B4A or B4X, and it is definitely not a complete Flutter implementation. It is just a small beta project with rough edges, created to explore whether this style of UI development feels useful in B4A. Is it revolutionary? Probably not. Is it useful? Maybe. I am sharing it mainly to get feedback. If you try... Read more

Hi there... Well, exploring the world of vibe coding, ahem, AI Assisted Engineering. What have you vibe coded today. Share it with us. #SharingTheGoodness

Hi Fam Experience on Vercel Download Code The first draft of the SithasoDaisy5 Demo Code Only Version is out. This demo has been built with code only and does not need abstract designer layouts to work. Why did we also consider this approach? We have recognized that some developers prefer to type code / use AI to code above and beyond using the abstract designer and we needed to make this option available. The code has been generated directly from the layouts, i.e. we look the existing layouts and just converted each component in them into b4x code, e.g. Initialize & AddComponent with properties settings in-between. We used the same code used from our BJL/BAL/JSON coding tool to assist with the conversion and a lot of ChatGPT Codex to get here This UI should be the same as the layout based version. You will need the SithasoDaisy5 b4xlib to run the source. #SharingTheGoodness Related Content... Read more

I am getting extra white space at the top of the screen on my Samsung Galaxy Tab A7 Lite. The first image is a Pixel 7 - it is fine. But The Samsung does this: Here is the code: B4X: IME.Initialize("IME") RootMain = xui.CreatePanel("") RootMain.Tag = "RootMain" Dim Content As Rect = IME.GetContentRect Activity.AddView(RootMain, Content.Left, Content.Top, Content.Width, Content.Height) IME.UpdatePercentageReference(RootMain.Width, RootMain.Height) RootMain.LoadLayout("Main") ' Activity.LoadLayout("Main") The designer layout looks correct when connected to the devices. Any ideas appreciated.

Hey there So I decided to try vibe coding a completely new web app using DaisyUI between everything Im trying to relearn in b4a. Just when I was about to present this, I was just requested to make it single user, multiple stores. Phew. Below is the single user single store version. So this is two apps, one admin and one for the "employees" who will actually do the stock take. I was just searching for a complete products db as I wanted to check this with a real product in my grocery cupboard, Open Food Facts proved helpful. Will check this out later today. I scanned a few things in my cupboard. Stock Take On Mobile App The app is hosted with pockethost (a pocketbase hosting platform). This already has https so the web camera works well. Vibe coded? What about SithasoDaisy5 ? After finalizing the process of writing AI skills for B4XDaisyUIKit , a lot was learned, so SithasoDaisy5 Skills is the next gate. I did start... Read more
