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.
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.
