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().
