\class QStylePlugin
\brief The QStylePlugin class provides an abstract base for custom QStyle plugins.
\ingroup plugins
QStylePlugin is a simple plugin interface that makes it easy
to create custom styles that can be loaded dynamically into
applications using the QStyleFactory class.
Writing a style plugin is achieved by subclassing this base class,
reimplementing the pure virtual keys() and create() functions, and
exporting the class using the Q_EXPORT_PLUGIN2() macro. See \l
{How to Create Qt Plugins} for details.
\sa QStyleFactory, QStyle
*/
/*!
\fn QStringList QStylePlugin::keys() const
Returns the list of style keys this plugin supports.
These keys are usually the class names of the custom styles that
are implemented in the plugin.
\sa create()
*/
/*!
\fn QStyle *QStylePlugin::create(const QString& key)
Creates and returns a QStyle object for the given style \a key.
If a plugin cannot create a style, it should return 0 instead.
The style key is usually the class name of the required
style. Note that the keys are case insensitive. For example:
\snippet doc/src/snippets/qstyleplugin/main.cpp 0
\codeline
\snippet doc/src/snippets/qstyleplugin/main.cpp 1
\snippet doc/src/snippets/qstyleplugin/main.cpp 2
\sa keys()
*/
/*!
Constructs a style plugin with the given \a parent.
Note that this constructor is invoked automatically by the
Q_EXPORT_PLUGIN2() macro, so there is no need for calling it
explicitly.
*/
QStylePlugin::QStylePlugin(QObject *parent)
: QObject(parent)
{
}
/*!
Destroys the style plugin.
Note that Qt destroys a plugin automatically when it is no longer
used, so there is no need for calling the destructor explicitly.
*/
QStylePlugin::~QStylePlugin()
{
