- \brief The QDeclarativeComponent class encapsulates a QML component description.
+ \brief The QDeclarativeComponent class encapsulates a QML component definition.
\mainclass
+
+ Components are reusable, encapsulated QML elements with well-defined interfaces.
+ They are often defined in \l {qdeclarativedocuments.html}{Component Files}.
+
+ A QDeclarativeComponent instance can be created from a QML file.
+ For example, if there is a \c main.qml file like this:
+
+ \qml
+ import Qt 4.7
+
+ Item {
+ width: 200
+ height: 200
+ }
+ \endqml
+
+ The following code loads this QML file as a component, creates an instance of
+ this component using create(), and then queries the \l Item's \l {Item::}{width}
+ value:
+
+ \code
+ QDeclarativeEngine *engine = new QDeclarativeEngine;
+ QDeclarativeComponent component(engine, QUrl::fromLocalFile("main.qml"));
+
+ QObject *myObject = component.create();
+ QDeclarativeItem *item = qobject_cast<QDeclarativeItem*>(myObject);
+ int width = item->width();
+ \endcode
