Подробное описаниеThe 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. Описание функций-членовQGenericPlugin::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(). |
