• Introducing the QML Live Preview MCP Tool for Agentic Development of Embedded Devices

  

  Agents Edit QML, But Don’t See the Result Without Building, Compiling, and Running

  AI agents can make many UI changes in a single iteration. AI agents edit files, maybe run a build, and then report success. Every change can costs a full rebuild and relaunch, or it goes unchecked by the developer. Qt's QML Live Preview MCP tool makes autonomous AI agent work transparent for the developer at a low token expense: it runs the app and hot reloads changed QML files, without a rebuild and without a restart.

• From Figma to Qt: A Comparison Between Manual and Assisted Workflows

  

  We know that one of the biggest challenges for embedded UI/UX designers is to see their design vision through to the final product.

• Figma to Qt 1.1: Test Design Live, Ship It Anywhere

  

  Click, drag, and tweak your design in Live Preview before a developer builds it. Ship the same workflow to flagship touchscreens and microcontrollers. And get more of what you draw back as native QML.

• Implementing Tracepoints in Qt Applications using Qt Creator 21

  Sometimes, as a developer, you need to find out why your application is misbehaving. The usual advice is to add tracing or use a profiler.

  The 6.12 release for Qt Framework is now available, with improved cybersecurity, UI performance, and a wealth of capabilities to mix-and-match from across your architectural layers. As a Long-Term Support release, Qt 6.12 is not a simple incremental update, but a culmination of various efforts started years ago. Take a closer look.

• Introducing the Canvas2D Coding Skill for Agentic Development of Embedded Device UIs

  

  The Challenge: Getting AI Agents to Draw Correct Canvas2D

  
  Qt 6.12 introduces Qt Canvas2D. Its API echoes the HTML5 canvas and the older Qt Quick Canvas element, both of which developers and AI models have seen many times in training data.
