详细描述
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.
成员函数
QGenericPlugin::QGenericPlugin(QObject *parent = Q_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.
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.
