Descripción detallada

The QWidgetPlugin class provides an abstract base for custom QWidget plugins.

The widget plugin is a simple plugin interface that makes it easy to create custom widgets that can be included in forms using Qt Designer and used by applications.

Writing a widget plugin is achieved by subclassing this base class, reimplementing the pure virtual functions keys(), create(), group(), iconSet(), includeFile(), toolTip(), whatsThis() and isContainer(), and exporting the class with the Q_EXPORT_PLUGIN macro.

See the Qt Designer manual's, 'Creating Custom Widgets' section in the 'Creating Custom Widgets' chapter, for a complete example of a QWidgetPlugin.

See also the Plugins documentation and the {QWidgetFactory} class that is supplied with Qt Designer.

Documentación del constructor y destructor

QWidgetPlugin::QWidgetPlugin

(

)

Constructs a widget plugin. This is invoked automatically by the Q_EXPORT_PLUGIN macro.

QWidgetPlugin::~QWidgetPlugin

(

)

Destroys the widget plugin.

You never have to call this explicitly. Qt destroys a plugin automatically when it is no longer used.

QWidgetPlugin::QWidgetPlugin

(

)

QWidgetPlugin::~QWidgetPlugin
