Detailed Description

The QGenericPlugin class is an abstract base class for window-system related plugins in Qt QPA.

Note that this class is only available in Qt QPA.

A mouse plugin can be created by subclassing QGenericPlugin and reimplementing the pure virtual keys() and create() functions. By exporting the derived class using the Q_EXPORT_PLUGIN2() macro, The default implementation of the QGenericPluginFactory class will automatically detect the plugin and load the driver into the server application at run-time. See How to Create Qt Plugins for details.

See also QGenericPluginFactory.

Member Function Documentation

QGenericPlugin::QGenericPlugin(QObject * parent = 0)

Constructs a plugin with the given parent.

Note that this constructor is invoked automatically by the Q_EXPORT_PLUGIN2() macro, so there is no need for calling it explicitly.

QGenericPlugin::~QGenericPlugin()

Destroys the plugin.

Note that Qt destroys a plugin automatically when it is no longer used, so there is no need for calling the destructor explicitly.

QObject * QGenericPlugin::create(const QString & key, const QString & specification) `[pure virtual]`

Implement this function to create a driver matching the type specified by the given key and specification parameters. Note that keys are case-insensitive.

See also keys().

QStringList QGenericPlugin::keys() const `[pure virtual]`

Implement this function to return the list of valid keys, i.e. the drivers supported by this plugin.

See also create().
