88 \class QQmlComponent -

89 \since 5.0 -

90 \inmodule QtQml -

91 -

92 \brief The QQmlComponent class encapsulates a QML component definition. -

93 -

94 Components are reusable, encapsulated QML types with well-defined interfaces. -

95 -

96 A QQmlComponent instance can be created from a QML file. -

97 For example, if there is a \c main.qml file like this: -

98 -

99 \qml -

100 import QtQuick 2.0 -

101 -

102 Item { -

103 width: 200 -

104 height: 200 -

105 } -

106 \endqml -

107 -

108 The following code loads this QML file as a component, creates an instance of -

109 this component using create(), and then queries the \l Item's \l {Item::}{width} -

110 value: -

111 -

112 \code -

113 QQmlEngine *engine = new QQmlEngine; -

114 QQmlComponent component(engine, QUrl::fromLocalFile("main.qml")); -

115 -

116 QObject *myObject = component.create(); -

117 QQuickItem *item = qobject_cast<QQuickItem*>(myObject); -

118 int width = item->width(); // width = 200 -

119 \endcode -

120 -

121 To create instances of a component in code where a QQmlEngine instance is -

122 not available, you can use \l qmlContext() or \l qmlEngine(). For example, -

123 in the scenario below, child items are being created within a QQuickItem -

124 subclass: -

125 -

126 \code -

127 void MyCppItem::init() -

128 { -

129 QQmlEngine *engine = qmlEngine(this); -

130 // Or: -

131 // QQmlEngine *engine = qmlContext(this)->engine(); -

132 QQmlComponent component(engine, QUrl::fromLocalFile("MyItem.qml")); -

133 QQuickItem *childItem = qobject_cast<QQuickItem*>(component.create()); -

134 childItem->setParentItem(this); -

135 } -

136 \endcode -

137 -

138 Note that these functions will return \c null when called inside the -

139 constructor of a QObject subclass, as the instance will not yet have -

140 a context nor engine. -

141 -

142 \section2 Network Components -

143 -

144 If the URL passed to QQmlComponent is a network resource, or if the QML document references a -

145 network resource, the QQmlComponent has to fetch the network data before it is able to create -

146 objects. In this case, the QQmlComponent will have a \l {QQmlComponent::Loading}{Loading} -

147 \l {QQmlComponent::status()}{status}. An application will have to wait until the component -

148 is \l {QQmlComponent::Ready}{Ready} before calling \l {QQmlComponent::create()}. -

149 -

150 The following example shows how to load a QML file from a network resource. After creating -

151 the QQmlComponent, it tests whether the component is loading. If it is, it connects to the -

152 QQmlComponent::statusChanged() signal and otherwise calls the \c {continueLoading()} method -

153 directly. Note that QQmlComponent::isLoading() may be false for a network component if the -

154 component has been cached and is ready immediately. -

155 -

156 \code -

157 MyApplication::MyApplication() -

158 { -

159 // ... -

160 component = new QQmlComponent(engine, QUrl("http://www.example.com/main.qml")); -

161 if (component->isLoading()) -

162 QObject::connect(component, SIGNAL(statusChanged(QQmlComponent::Status)), -

163 this, SLOT(continueLoading())); -

164 else -

165 continueLoading(); -

166 } -

167 -

168 void MyApplication::continueLoading() -

169 { -

170 if (component->isError()) { -

171 qWarning() << component->errors(); -

172 } else { -

173 QObject *myObject = component->create(); -

174 } -

175 } -

176 \endcode -

177 -

178 Note that the \l {Qt Quick 1} version is named QDeclarativeComponent. -

182 \qmltype Component -

183 \instantiates QQmlComponent -

184 \ingroup qml-utility-elements -

185 \inqmlmodule QtQml -

186 \brief Encapsulates a QML component definition. -

187 -

188 Components are reusable, encapsulated QML types with well-defined interfaces. -

189 -

190 Components are often defined by \l {{QML Documents}}{component files} - -

191 that is, \c .qml files. The \e Component type essentially allows QML components -

192 to be defined inline, within a \l {QML Documents}{QML document}, rather than as a separate QML file. -

193 This may be useful for reusing a small component within a QML file, or for defining -

194 a component that logically belongs with other QML components within a file. -

195 -

196 For example, here is a component that is used by multiple \l Loader objects. -

197 It contains a single item, a \l Rectangle: -

198 -

199 \snippet qml/component.qml 0 -

200 -

201 Notice that while a \l Rectangle by itself would be automatically -

202 rendered and displayed, this is not the case for the above rectangle -

203 because it is defined inside a \c Component. The component encapsulates the -

204 QML types within, as if they were defined in a separate QML -

205 file, and is not loaded until requested (in this case, by the -

206 two \l Loader objects). Because Component is not derived from Item, you cannot -

207 anchor anything to it. -

208 -

209 Defining a \c Component is similar to defining a \l {QML Documents}{QML document}. -

210 A QML document has a single top-level item that defines the behavior and -

211 properties of that component, and cannot define properties or behavior outside -

212 of that top-level item. In the same way, a \c Component definition contains a single -

213 top level item (which in the above example is a \l Rectangle) and cannot define any -

214 data outside of this item, with the exception of an \e id (which in the above example -

215 is \e redSquare). -

216 -

217 The \c Component type is commonly used to provide graphical components -

218 for views. For example, the ListView::delegate property requires a \c Component -

219 to specify how each list item is to be displayed. -

220 -

221 \c Component objects can also be created dynamically using -

222 \l{QtQml::Qt::createComponent()}{Qt.createComponent()}. -

223 -

224 \section2 Creation Context -

225 -

226 The creation context of a Component corresponds to the context where the Component was declared. -

227 This context is used as the parent context (creating a \l{qtqml-documents-scope.html#component-instance-hierarchy}{context hierarchy}) -

228 when the component is instantiated by an object such as a ListView or a Loader. -

229 -

230 In the following example, \c comp1 is created within the root context of MyItem.qml, and any objects -

231 instantiated from this component will have access to the ids and properties within that context, -

232 such as \c internalSettings.color. When \c comp1 is used as a ListView delegate in another context -

233 (as in main.qml below), it will continue to have access to the properties of its creation context -

234 (which would otherwise be private to external users). -

235 -

236 \table -

237 \row -

238 \li MyItem.qml -

239 \li \snippet qml/component/MyItem.qml 0 -

240 \row -

241 \li main.qml -

242 \li \snippet qml/component/main.qml 0 -

243 \endtable -

244 -

245 It is important that the lifetime of the creation context outlive any created objects. See -

246 \l{Maintaining Dynamically Created Objects} for more details. -

247 */ -

248 -

249 /*! -

250 \qmlattachedsignal Component::completed() -

251 -

252 Emitted after the object has been instantiated. This can be used to -

253 execute script code at startup, once the full QML environment has been -

254 established. -

255 -

256 The corresponding handler is \c onCompleted. It can be declared on -

257 any object. The order of running the \c onCompleted handlers is -

258 undefined. -

259 -

260 \qml -

261 Rectangle { -

262 Component.onCompleted: console.log("Completed Running!") -

263 Rectangle { -

264 Component.onCompleted: console.log("Nested Completed Running!") -

265 } -

266 } -

267 \endqml -

268 */ -

269 -

270 /*! -

271 \qmlattachedsignal Component::destruction() -

272 -

273 Emitted as the object begins destruction. This can be used to undo -

274 work done in response to the \l {completed}{completed()} signal, or other -

275 imperative code in your application. -

276 -

277 The corresponding handler is \c onDestruction. It can be declared on -

278 any object. The order of running the \c onDestruction handlers is -

279 undefined. -

282 Rectangle { -

283 Component.onDestruction: console.log("Destruction Beginning!") -

781 This method provides advanced control over component instance creation. -

782 In general, programmers should use QQmlComponent::create() to create object -

783 instances. -

784 -

785 Create an object instance from this component. Returns 0 if creation -

786 failed. \a publicContext specifies the context within which to create the object -

787 instance. -

788 -

789 When QQmlComponent constructs an instance, it occurs in three steps: -

790 \list 1 -

791 \li The object hierarchy is created, and constant values are assigned. -

792 \li Property bindings are evaluated for the first time. -

793 \li If applicable, QQmlParserStatus::componentComplete() is called on objects. -

794 \endlist -

795 QQmlComponent::beginCreate() differs from QQmlComponent::create() in that it -

796 only performs step 1. QQmlComponent::completeCreate() must be called to -

797 complete steps 2 and 3. -

798 -

799 This breaking point is sometimes useful when using attached properties to -

800 communicate information to an instantiated component, as it allows their -

801 initial values to be configured before property bindings take effect. -

802 -

803 The ownership of the returned object instance is transferred to the caller. -

1169 \qmlmethod object Component::createObject(QtObject parent, object properties) -

1170 -

1171 Creates and returns an object instance of this component that will have -

1172 the given \a parent and \a properties. The \a properties argument is optional. -

1173 Returns null if object creation fails. -

1174 -

1175 The object will be created in the same context as the one in which the component -

1176 was created. This function will always return null when called on components -

1177 which were not created in QML. -

1178 -

1179 If you wish to create an object without setting a parent, specify \c null for -

1180 the \a parent value. Note that if the returned object is to be displayed, you -

1181 must provide a valid \a parent value or set the returned object's \l{Item::parent}{parent} -

1182 property, otherwise the object will not be visible. -

1183 -

1184 If a \a parent is not provided to createObject(), a reference to the returned object must be held so that -

1185 it is not destroyed by the garbage collector. This is true regardless of whether \l{Item::parent} is set afterwards, -

1186 because setting the Item parent does not change object ownership. Only the graphical parent is changed. -

1187 -

1188 As of \c {QtQuick 1.1}, this method accepts an optional \a properties argument that specifies a -

1189 map of initial property values for the created object. These values are applied before the object -

1190 creation is finalized. This is more efficient than setting property values after object creation, -

1191 particularly where large sets of property values are defined, and also allows property bindings -

1192 to be set up (using \l{Qt::binding}{Qt.binding}) before the object is created. -

1193 -

1194 The \a properties argument is specified as a map of property-value items. For example, the code -

1195 below creates an object with initial \c x and \c y values of 100 and 100, respectively: -

1196 -

1197 \js -

1198 var component = Qt.createComponent("Button.qml"); -

1199 if (component.status == Component.Ready) -

1200 component.createObject(parent, {"x": 100, "y": 100}); -

1201 \endjs -

1202 -

1203 Dynamically created instances can be deleted with the \c destroy() method. -

1204 See \l {Dynamic QML Object Creation from JavaScript} for more information. -

1311 \qmlmethod object Component::incubateObject(Item parent, object properties, enumeration mode) -

1312 -

1313 Creates an incubator for an instance of this component. Incubators allow new component -

1314 instances to be instantiated asynchronously and do not cause freezes in the UI. -

1315 -

1316 The \a parent argument specifies the parent the created instance will have. Omitting the -

1317 parameter or passing null will create an object with no parent. In this case, a reference -

1318 to the created object must be held so that it is not destroyed by the garbage collector. -

1319 -

1320 The \a properties argument is specified as a map of property-value items which will be -

1321 set on the created object during its construction. \a mode may be Qt.Synchronous or -

1322 Qt.Asynchronous, and controls whether the instance is created synchronously or asynchronously. -

1323 The default is asynchronous. In some circumstances, even if Qt.Synchronous is specified, -

1324 the incubator may create the object asynchronously. This happens if the component calling -

1325 incubateObject() is itself being created asynchronously. -

1327 All three arguments are optional. -

1328 -

1329 If successful, the method returns an incubator, otherwise null. The incubator has the following -

1330 properties: -

1331 -

1332 \list -

1333 \li status The status of the incubator. Valid values are Component.Ready, Component.Loading and -

1334 Component.Error. -

1335 \li object The created object instance. Will only be available once the incubator is in the -

1336 Ready status. -

1337 \li onStatusChanged Specifies a callback function to be invoked when the status changes. The -

1338 status is passed as a parameter to the callback. -

1339 \li forceCompletion() Call to complete incubation synchronously. -

1340 \endlist -

1341 -

1342 The following example demonstrates how to use an incubator: -

1343 -

1344 \js -

1345 var component = Qt.createComponent("Button.qml"); -

1346 -

1347 var incubator = component.incubateObject(parent, { x: 10, y: 10 }); -

1348 if (incubator.status != Component.Ready) { -

1349 incubator.onStatusChanged = function(status) { -

1350 if (status == Component.Ready) { -

1351 print ("Object", incubator.object, "is now ready!"); -

1352 } -

1353 } -

1354 } else { -

1355 print ("Object", incubator.object, "is ready immediately!"); -

1356 } -

1357 \endjs -

1358 -

1359 Dynamically created instances can be deleted with the \c destroy() method. -

1360 See \l {Dynamic QML Object Creation from JavaScript} for more information. -
