Usage

Overview

The QStylePlugin class provides an abstract base for custom QStyle plugins.

The style plugin is a simple plugin interface that makes it easy to create custom styles that can be loaded dynamically into applications with a QStyleFactory.

Writing a style plugin is achieved by subclassing this base class, reimplementing the pure virtual functions keys() and create(), and exporting the class with the Q_EXPORT_PLUGIN macro. See the plugins documentation for an example.

See also Plugins.

Member function documentation

QStylePlugin::QStylePlugin ()

Constructs a style plugin. This is invoked automatically by the Q_EXPORT_PLUGIN macro.

QStylePlugin::~QStylePlugin ()

Destroys the style plugin.

You never have to call this explicitly. Qt destroys a plugin automatically when it is no longer used.

QStyle * QStylePlugin::create ( const QString & key ) [pure virtual]

Creates and returns a QStyle object for the style key key. The style key is usually the class name of the required style.

See also keys().

QStringList QStylePlugin::keys () const [pure virtual]

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.
