\brief The Loader item allows dynamically loading an Item-based
subtree from a URL or Component.
- The Loader element instantiates an item from a component. The component to
- be instantiated may be specified directly by the \l sourceComponent
- property, or loaded from a URL via the \l source property.
+ Loader is used to dynamically load visual QML components. It can load a
+ QML file (using the \l source property) or a \l Component object (using
+ the \l sourceComponent property). It is useful for delaying the creation
+ of a component until it is required: for example, when a component should
+ be created on demand, or when a component should not be created
+ unnecessarily for performance reasons.
- Loader can be used to delay the creation of a component until it
- is required. For example, this loads "Page1.qml" as a component
- into the Loader element, when the \l MouseArea is clicked:
+ Here is a Loader that loads "Page1.qml" as a component when the
+ \l MouseArea is clicked:
- \code
- import Qt 4.7
+ \snippet doc/src/snippets/declarative/loader/simple.qml 0
- Item {
- width: 200; height: 200
+ The loaded item can be accessed using the \l item property.
- MouseArea {
- anchors.fill: parent
- onClicked: pageLoader.source = "Page1.qml"
- }
+ Loader is like any other visual item and must be positioned and sized
+ accordingly to become visible. Once the component is loaded, the Loader
+ is automatically resized to the size of the component.
- Loader { id: pageLoader }
- }
- \endcode
+ If the \l source or \l sourceComponent changes, any previously instantiated
+ items are destroyed. Setting \l source to an empty string or setting
+ \l sourceComponent to \c undefined destroys the currently loaded item,
+ freeing resources and leaving the Loader empty.
+
+
+ \section2 Receiving signals from loaded items
- Note that Loader is like any other graphical Item and needs to be positioned
- and sized accordingly to become visible. When a component is loaded, the
- Loader is automatically resized to the size of the component.
+ Any signals emitted from the loaded item can be received using the
+ \l Connections element. For example, the following \c application.qml
+ loads \c MyItem.qml, and is able to receive the \c message signal from
+ the loaded item through a \l Connections object:
- If the Loader source is changed, any previous items instantiated
- will be destroyed. Setting \l source to an empty string, or setting
- sourceComponent to \e undefined
- will destroy the currently instantiated items, freeing resources
- and leaving the Loader empty. For example:
+ \table
+ \row
+ \o application.qml
+ \o MyItem.qml
+ \row
+ \o \snippet doc/src/snippets/declarative/loader/connections.qml 0
+ \o \snippet doc/src/snippets/declarative/loader/MyItem.qml 0
+ \endtable
- \code
- pageLoader.source = ""
- \endcode
+ Alternatively, since \c MyItem.qml is loaded within the scope of the
+ Loader, it could also directly call any function defined in the Loader or
+ its parent \l Item.
- or
- \code
- pageLoader.sourceComponent = undefined
- \endcode
+ \section2 Focus and key events
- unloads "Page1.qml" and frees resources consumed by it.
+ Loader is a focus scope. Its \l {Item::}{focus} property must be set to
+ \c true for any of its children to get the \e {active focus}. (See
+ \l{qmlfocus#Acquiring Focus and Focus Scopes}{the focus documentation page}
+ for more details.) Any key events received in the loaded item should likely
+ also be \l {KeyEvent::}{accepted} so they are not propagated to the Loader.
- Note that Loader is a focus scope. Its \c focus property must be set to \c true for any of its children
- to get the \e {active focus} (see \l{qmlfocus#Acquiring Focus and Focus Scopes}{the focus documentation page} for more details).
+ For example, the following \c application.qml loads \c KeyReader.qml when
+ the \l MouseArea is clicked. Notice the \l {Item::}{focus} property is
+ set to \c true for the Loader as well as the \l Item in the dynamically
+ loaded object:
+
+ \table
+ \row
+ \o application.qml
+ \o KeyReader.qml
+ \row
+ \o \snippet doc/src/snippets/declarative/loader/focus.qml 0
+ \o \snippet doc/src/snippets/declarative/loader/KeyReader.qml 0
+ \endtable
+
+ Once \c KeyReader.qml is loaded, it accepts key events and sets
+ \c event.accepted to \c true so that the event is not propagated to the
+ parent \l Rectangle.
