166 \qmltype Loader -

167 \instantiates QQuickLoader -

168 \inqmlmodule QtQuick -

169 \ingroup qtquick-dynamic -

170 \inherits Item -

171 -

172 \brief Allows dynamic loading of a subtree from a URL or Component. -

173 -

174 Loader is used to dynamically load QML components. -

175 -

176 Loader can load a -

177 QML file (using the \l source property) or a \l Component object (using -

178 the \l sourceComponent property). It is useful for delaying the creation -

179 of a component until it is required: for example, when a component should -

180 be created on demand, or when a component should not be created -

181 unnecessarily for performance reasons. -

182 -

183 Here is a Loader that loads "Page1.qml" as a component when the -

184 \l MouseArea is clicked: -

185 -

186 \snippet qml/loader/simple.qml 0 -

187 -

188 The loaded object can be accessed using the \l item property. -

189 -

190 If the \l source or \l sourceComponent changes, any previously instantiated -

191 items are destroyed. Setting \l source to an empty string or setting -

192 \l sourceComponent to \c undefined destroys the currently loaded object, -

193 freeing resources and leaving the Loader empty. -

194 -

195 \section2 Loader Sizing Behavior -

196 -

197 If the source component is not an Item type, Loader does not -

198 apply any special sizing rules. When used to load visual types, -

199 Loader applies the following sizing rules: -

200 -

201 \list -

202 \li If an explicit size is not specified for the Loader, the Loader -

203 is automatically resized to the size of the loaded item once the -

204 component is loaded. -

205 \li If the size of the Loader is specified explicitly by setting -

206 the width, height or by anchoring, the loaded item will be resized -

207 to the size of the Loader. -

208 \endlist -

209 -

210 In both scenarios the size of the item and the Loader are identical. -

211 This ensures that anchoring to the Loader is equivalent to anchoring -

212 to the loaded item. -

213 -

214 \table -

215 \row -

216 \li sizeloader.qml -

217 \li sizeitem.qml -

218 \row -

219 \li \snippet qml/loader/sizeloader.qml 0 -

220 \li \snippet qml/loader/sizeitem.qml 0 -

221 \row -

222 \li The red rectangle will be sized to the size of the root item. -

223 \li The red rectangle will be 50x50, centered in the root item. -

224 \endtable -

225 -

226 -

227 \section2 Receiving Signals from Loaded Objects -

228 -

229 Any signals emitted from the loaded object can be received using the -

230 \l Connections type. For example, the following \c application.qml -

231 loads \c MyItem.qml, and is able to receive the \c message signal from -

232 the loaded item through a \l Connections object: -

233 -

234 \table 70% -

235 \row -

236 \li application.qml -

237 \li MyItem.qml -

238 \row -

239 \li \snippet qml/loader/connections.qml 0 -

240 \li \snippet qml/loader/MyItem.qml 0 -

241 \endtable -

242 -

243 Alternatively, since \c MyItem.qml is loaded within the scope of the -

244 Loader, it could also directly call any function defined in the Loader or -

245 its parent \l Item. -

246 -

247 -

248 \section2 Focus and Key Events -

249 -

250 Loader is a focus scope. Its \l {Item::}{focus} property must be set to -

251 \c true for any of its children to get the \e {active focus}. (See -

252 \l{Keyboard Focus in Qt Quick} -

253 for more details.) Any key events received in the loaded item should likely -

254 also be \l {KeyEvent::}{accepted} so they are not propagated to the Loader. -

255 -

256 For example, the following \c application.qml loads \c KeyReader.qml when -

257 the \l MouseArea is clicked. Notice the \l {Item::}{focus} property is -

258 set to \c true for the Loader as well as the \l Item in the dynamically -

259 loaded object: -

260 -

261 \table -

262 \row -

263 \li application.qml -

264 \li KeyReader.qml -

265 \row -

266 \li \snippet qml/loader/focus.qml 0 -

267 \li \snippet qml/loader/KeyReader.qml 0 -

268 \endtable -

269 -

270 Once \c KeyReader.qml is loaded, it accepts key events and sets -

271 \c event.accepted to \c true so that the event is not propagated to the -

272 parent \l Rectangle. -

273 -

274 Since \c {QtQuick 2.0}, Loader can also load non-visual components. -

275 -

276 \section2 Using a Loader within a View Delegate -

277 -

278 In some cases you may wish to use a Loader within a view delegate to improve delegate -

279 loading performance. This works well in most cases, but there is one important issue to -

280 be aware of related to the \l{QtQml::Component#Creation Context}{creation context} of a Component. -

281 -

282 In the following example, the \c index context property inserted by the ListView into \c delegateComponent's -

283 context will be inaccessible to Text, as the Loader will use the creation context of \c myComponent as the parent -

284 context when instantiating it, and \c index does not refer to anything within that context chain. -

285 -

286 \snippet qml/loader/creationContext1.qml 0 -

287 -

288 In this situation we can either move the component inline, -

289 -

290 \snippet qml/loader/creationContext2.qml 0 -

291 -

292 into a separate file, -

293 -

294 \snippet qml/loader/creationContext3.qml 0 -

295 -

296 or explicitly set the required information as a property of the Loader (this works because the -

297 Loader sets itself as the context object for the component it is loading). -

298 -

299 \snippet qml/loader/creationContext4.qml 0 -

300 -

517 will be accessible via the \l item property once loading and instantiation -

520 If the \l active property is \c false at the time when this function is called, -

743 \qmlproperty enumeration QtQuick::Loader::status -

744 -

745 This property holds the status of QML loading. It can be one of: -

746 \list -

747 \li Loader.Null - the loader is inactive or no QML source has been set -

748 \li Loader.Ready - the QML source has been loaded -

749 \li Loader.Loading - the QML source is currently being loaded -

750 \li Loader.Error - an error occurred while loading the QML source -

751 \endlist -

752 -

753 Use this status to provide an update or respond to the status change in some way. -

754 For example, you could: -

755 -

756 \list -

757 \li Trigger a state change: -

758 \qml -

759 State { name: 'loaded'; when: loader.status == Loader.Ready } -

760 \endqml -

761 -

762 \li Implement an \c onStatusChanged signal handler: -

763 \qml -

764 Loader { -

765 id: loader -

766 onStatusChanged: if (loader.status == Loader.Ready) console.log('Loaded') -

767 } -

768 \endqml -

769 -

770 \li Bind to the status value: -

771 \qml -

772 Text { text: loader.status == Loader.Ready ? 'Loaded' : 'Not loaded' } -

773 \endqml -

774 \endlist -

775 -

776 Note that if the source is a local file, the status will initially be Ready (or Error). While -

777 there will be no onStatusChanged signal in that case, the onLoaded will still be invoked. -

877 \qmlproperty bool QtQuick::Loader::asynchronous -

878 -

879 This property holds whether the component will be instantiated asynchronously. -

880 By default it is \c false. -

881 -

882 When used in conjunction with the \l source property, loading and compilation -

883 will also be performed in a background thread. -

884 -

885 Loading asynchronously creates the objects declared by the component -

886 across multiple frames, and reduces the -

887 likelihood of glitches in animation. When loading asynchronously the status -

888 will change to Loader.Loading. Once the entire component has been created, the -

889 \l item will be available and the status will change to Loader.Ready. -

890 -

891 Changing the value of this property to \c false while an asynchronous load is in -

892 progress will force immediate, synchronous completion. This allows beginning an -

893 asynchronous load and then forcing completion if the Loader content must be -

894 accessed before the asynchronous load has completed. -

895 -

896 To avoid seeing the items loading progressively set \c visible appropriately, e.g. -

897 -

898 \code -

899 Loader { -

900 source: "mycomponent.qml" -

901 asynchronous: true -

902 visible: status == Loader.Ready -

903 } -

904 \endcode -

907 loading a component asynchronously via a network. -
