\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.
|

Q_EXPORT_PLUGIN2() macro, so there is no need for calling it
|
|
explicitly.

Destroys the style plugin.

Note that Qt destroys a plugin automatically when it is no longer
