Detailed Description

The QGenericPlugin class is an abstract base class for plugins.

A mouse plugin can be created by subclassing QGenericPlugin and reimplementing the pure virtual create() function. By exporting the derived class using the Q_PLUGIN_METADATA() 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.

The json metadata file should contain a list of keys supported by this plugin.

See also QGenericPluginFactory.

Member Function Documentation

QGenericPlugin::QGenericPlugin(QObject *parent = nullptr)

Constructs a plugin with the given parent.

Note that this constructor is invoked automatically by the moc generated code that exports the plugin, so there is no need for calling it explicitly.

[virtual] 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.

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

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