Qt
Qt is a cross-platform C++ application development framework widely used for developing graphical user interface programs, and also supports the development of non-GUI programs.

Pages embedded in WebView are an independent browser engine, and their DOM tree is isolated from the Qt widget tree, so they need to be accessed through different mechanisms respectively.
Calibre is a typical Qt+WebView hybrid: the application shell is built with Qt, but the e-book reading interface actually embeds a web engine.
The Widget Tree in the Qt framework is the structure within a Qt application that represents the hierarchical relationships of UI elements, where each window, button, input box, etc. is a QObject node.
Automation tools access the Qt widget tree through the QAccessible interface or Qt's private APIs, thereby locating and operating widgets.
QuickShell is a desktop shell framework built on Qt/QML that allows interface components such as status bars, launchers and notification centers to be written in declarative QML and shares data among multiple components through a unified state service.
Calamares is a distribution-independent system installer framework adopted by many distributions such as Manjaro, KDE Neon and Garuda Linux, featuring a modular design and a Qt-based interface.
Immediate-mode GUIs re-describe the entire UI from scratch on every frame with state managed by the caller, while retained-mode frameworks (such as Qt and WinForms) maintain a persistent UI component tree in memory and let the framework handle state and redraws
KDE is based on the Qt framework, and some KDE applications such as Kdenlive and Krita are also available on Windows and macOS.

wxWidgets adopts a native control rendering strategy, calling the native UI components of each platform, which contrasts with Qt's self-drawing approach.
