💡 This Skill requires PySide6, and includes scripts (resource) components.

What problem does it solve?

Automates offscreen captures of Qt widgets to enable visual verification without showing windows.

Core Features & Use Cases

  • Offscreen capture of PySide6 widgets for visual testing without GUI rendering.
  • Supports single widgets, dialogs, and complex layouts for GUI verification and regression checks.
  • Use with vision tools to analyze screenshots to confirm correct rendering and layout.

Quick Start

Use the qt-testing skill to capture a Qt widget offscreen by running the script or importing the helper. uv run --with PySide6 python .claude/skills/qt-testing/scripts/qt_capture.py Or import and use the helper: from scripts.qt_capture import capture_widget app = init_qt() widget = QWidget() path = capture_widget(widget, "example")

FAQPage Schema
How do I capture Qt widgets offscreen for visual testing?▼

Capture Qt widgets offscreen by running the qt_capture script with PySide6 or importing the capture_widget helper function to render and save screenshots without displaying a GUI window.

What is offscreen GUI testing used for in PySide6 development?▼

Offscreen GUI testing renders PySide6 widgets to image files without showing windows, enabling automated visual verification of layouts, dialogs, and individual widgets during development and QA.

Can I use this to test complex PySide6 dialogs and layouts?▼

Yes, the offscreen capture supports single widgets, dialogs, and complex layouts in PySide6, allowing you to perform visual verification and regression checks across various GUI components.

Do I need PySide6 installed to capture Qt widgets offscreen?▼

Yes, PySide6 is a required Python dependency to render and capture Qt widgets offscreen, alongside a minimal Python runtime to execute the capture scripts and save screenshots.

How do I analyze offscreen screenshots for Qt visual inspection?▼

You analyze offscreen screenshots by passing the saved image files to vision-based analysis tools, which inspect the visual rendering to confirm correct widget layout and GUI formatting.
