+\title Qt Widgets
+\brief A module which provides a set of C++ technologies for building user
+interfaces
+
+Qt Widgets is a module which provides primary elements for building user
+interfaces in C++.
+
+\section1 Getting Started
+
+ To include the definitions of the module's classes, use the
+ following directive:
+
+ \snippet code/doc_src_qtwidgets.cpp 1
+
+ To link against the module, add this line to your \l qmake \c
+ .pro file:
+
+ \snippet code/doc_src_qtwidgets.pro 0
+
+\section1 Widgets
+
+ Widgets are for building C++ user interfaces. They are customizable with
+ layouts and stylesheets.

+ \li \l{Application Main Window}

+
+ Qt's support for widget styles and themes enables your application to fit in
+ with the native desktop environment. Below, you can find links to the
+ various widget styles that are supplied with Qt Widgets.

+ \li \l{GTK Style Widget Gallery}
+ \li \l{Macintosh Style Widget Gallery}
+ \endlist
+
+ \section2 Layouts
+
+ Widgets may use to automatically arrange child widgets within their
+ container. Each widget reports its size requirements to the layout and the
+ layout distributes the available space accordingly.
+

+ \li \l{Widgets and Layouts}
+ \li \l{Qt Designer Integration}
+ \li \l{Layout Management}
+ \endlist
+
+ \section2 Style Sheets
+
+ \l{Qt Style Sheets} are a powerful mechanism that allows for customization
+ of the appearance of widgets. The concepts, terminology, and syntax of Qt
+ Style Sheets are heavily inspired by HTML Cascading Style Sheets (CSS) but
+ adapted to the world of widgets.

+ \li \l{The Style Sheet Syntax}
+ \li \l{Styles and Style Aware Widgets}
+ \li \l{Qt Style Sheets Examples}
+ \endlist
+
+\section1 Graphics View
+
+ The \l{Graphics View Framework} is for managing and interacting with a large
+ number of custom-made 2D graphical items, and a view widget for visualizing
+ the items, with support for zooming and rotation.
+
+\section1 Model/View
+
+ The \l{Model/View Programming}{model/view} architecture provides classes
+ that manage the way data is presented to the user. Data-driven applications
+ which use lists and tables are structured to separate the data and view
+ using models, views, and delegates.

is the way the java style does it (through QCommonStyle).
Alternatively, you can implement QStyle::layoutSpacing() and

this part of the layout. In these functions you can calculate the
spacing based on control types (QSizePolicy::ControlType) for
different size policies (QSizePolicy::Policy) and also the style

The sub-classes of QStyleOption contain all information necessary

usually on the stack - and filled out by the caller of the QStyle
function. Depending on what is drawn the style will expect

boxes. We have edited the QCommonStyle code somewhat to remove
code that is not directly relevant for check box styling.

We start with a look at how QCheckBox builds it style option,
which is QStyleOptionButton for checkboxes:
As mentioned, the style calculates the size of the widgets
contents, which the widgets calculate their size hints from. In
addition, complex controls also use the style to test which
