• Qt Design Studio 4.8.2 Released

  

  Qt Design Studio 4.8.2 Is Here!

  Following our 4.8.1 release, which introduced the Qt Design Studio AI Assistant in beta, we are back with a significant evolution of that feature, along with a few other updates. The 4.8.1 release laid the groundwork, a prompt-based tool that could generate QML from a natural language description or an image. That was a strong foundation, and the feedback we received helped shape where we took it next. In 4.8.2, the assistant has been rebuilt around a fundamentally more powerful architecture, and the difference in what you can accomplish with it is substantial.

  Qt Design Studio Goes Agentic

  With 4.8.2, Qt Design Studio takes a major step forward by introducing a fully agentic AI Assistant powered by the Model Context Protocol (MCP), an open standard for connecting AI models to external tools and data sources.
  
  This shift transforms the assistant from a passive helper into an active collaborator. Instead of working on a single file, it now understands your entire project structure and can operate across it using a rich set of MCP tools: reading files, creating components, modifying existing ones, and more.
  
  When you describe a goal, the assistant enters an agentic loop. It plans the task, selects the appropriate tools, executes them, evaluates the results, and continues iterating until the objective is complete. Every step is logged in the chat, so you can follow the process. Built on MCP, the assistant is designed to be extensible and future-proof, enabling integrations with external MCP server.
  
  The assistant supports leading models from Anthropic, Google, and OpenAI, and you can switch between providers within the same conversation. The agentic AI assistant is available to all Qt Design Studio users, we encourage you to try it out and share your feedback.

• Introducing the QML Profiler Skill for Agentic Development

  

  Instead of a painstaking row-by-row or slow flame graph reviews, the QML profiler skill for agentic development allows developers to delegate code performance profiling to AI agents.
  
  The skill guides the developer through the workflow, triggers the QML profiler, crunches through the resulting raw data, presents the performance bottlenecks in a concise report, and suggests improvements.
  
  The skill targets 2D Qt Quick applications and supports four profiling modes — rendering, logic, memory, and full. It can also analyze an existing trace file directly, without re-running the application, for example, if the performance trace has been run on the target hardware.

• Introducing the Qt Code Review Skills for Agentic Code Review

  

  Reviewing, auditing, or sanity-checking code usually means running separate linters, reading through checklists, and manually verifying Qt-specific patterns across dozens of files. The Qt code review skills help developers to automate part of this code review phase. Developers avoid a laborious manual walkthrough of every file, with the AI agent running a deterministic linter followed by six parallel deep-analysis agents and surfacing real issues with mitigations in a few minutes.

• Using the WebView module with C++ and Qt Widgets

  For a long time, developers of Qt-based C++ applications have only had one option for embedding web content: Qt WebEngine. And while it offers a large API with many useful features, the module has its downsides, since it can consume a lot of system resources and increase binary size. For QML users, we’ve had an alternative in the Qt WebView module, but that API had never been exposed to C++ until now.

• Security advisory: QML Code Injection in VectorImage Component in Qt declarative module impacts Qt

  Improper Control of Generation of Code ('Code Injection') vulnerability in the VectorImage component of the Qt declarative module has been discovered and has been assigned the CVE id CVE-2025-14576.

  Hello Qt,

• Figma to Qt 1.0 Is Here: The Most Reliable Way to Bring Your Design From Figma to Device

  

  When a perfectly crafted design leaves Figma and enters a development pipeline, things often get compromised. Spacing shifts, colors change, and details deviate through multiple layers of interpretation and unexpected limitations. You will see timelines lagging, design becoming unclear, and user experience losing priority.

  Figma to Qt is built to ensure your GUI designs get from Figma to device.

  Version 1.0 is now available for free download in the Figma Community.
