    \title Qt Labs StyleKit
    \brief A high-level styling API for Qt Quick Controls

    StyleKit is a declarative styling system for \l {Qt Quick Controls}, built on top of
    \l {Qt Quick Templates 2}{Qt Quick Templates}. It lets you define a complete visual style
    for all your controls from a single \l Style object, including support for
    \l {Theme}{themes}, \l {ControlStateStyle}{state-based} styling, and
    \l {ControlStateStyle::transition}{transitions}.
    StyleKit handles the underlying template implementation automatically, letting you focus
    purely on visual aspects such as
    \l {DelegateStyle::color}{colors},
    \l {DelegateStyle::implicitWidth}{dimensions},
    \l {DelegateStyle::border}{borders}, and
    \l {DelegateStyle::shadow}{shadows}.

    A key strength of StyleKit is its hierarchical property system: set a property once
    on a base type like \l {AbstractStylableControls::}{abstractButton}, and it
    automatically applies to all button-like controls.
    Override it where needed for specific controls or states. Changes to your
    style are instantly reflected across all controls, ensuring consistency while still
    allowing fine-grained customization.

    For controls that need custom behavior beyond what StyleKit provides, you can still
    implement custom templates and integrate them seamlessly alongside StyleKit-styled
    controls.

    \section1 Key Features

    \list
        \li \b{Declarative Styling} - An easy-to-use QML API that lets you focus on design over implementation
        \li \b{Hierarchical Fallbacks} - All properties propagate. Set them once, override where needed
        \li \b{State-Based Styling} - Design separate appearances for hovered, pressed, focused, etc.
        \li \b{Animated Transitions} - Define smooth animations between states
        \li \b{Theme Support} - Design light and dark themes, and any number of custom themes
        \li \b{Variations} - Design multiple variations of the same controls
        \li \b{Palette and Font Integration} - Configure control palettes and fonts using QML
    \endlist

    The following example shows a minimal example of a Style:

    This is how to set the style in your application:

    \section1 Using the Module in your Project
    The QML types of the module are available through the \c QtQuick.labs.StyleKit import.
    To use the types, add the following import statement to your .qml file:

    \qml
    import Qt.labs.StyleKit
    \endqml
