82 \class QJSEngine -

83 \reentrant -

84 -

85 \brief The QJSEngine class provides an environment for evaluating JavaScript code. -

86 -

87 \ingroup qtjavascript -

88 \inmodule QtQml -

89 -

90 \section1 Evaluating Scripts -

91 -

92 Use evaluate() to evaluate script code. -

93 -

94 \snippet code/src_script_qjsengine.cpp 0 -

95 -

96 evaluate() returns a QJSValue that holds the result of the -

97 evaluation. The QJSValue class provides functions for converting -

98 the result to various C++ types (e.g. QJSValue::toString() -

99 and QJSValue::toNumber()). -

100 -

101 The following code snippet shows how a script function can be -

102 defined and then invoked from C++ using QJSValue::call(): -

103 -

104 \snippet code/src_script_qjsengine.cpp 1 -

105 -

106 As can be seen from the above snippets, a script is provided to the -

107 engine in the form of a string. One common way of loading scripts is -

108 by reading the contents of a file and passing it to evaluate(): -

109 -

110 \snippet code/src_script_qjsengine.cpp 2 -

111 -

112 Here we pass the name of the file as the second argument to -

113 evaluate(). This does not affect evaluation in any way; the second -

114 argument is a general-purpose string that is stored in the \c Error -

115 object for debugging purposes. -

116 -

117 \section1 Engine Configuration -

118 -

119 The globalObject() function returns the \b {Global Object} -

120 associated with the script engine. Properties of the Global Object -

121 are accessible from any script code (i.e. they are global -

122 variables). Typically, before evaluating "user" scripts, you will -

123 want to configure a script engine by adding one or more properties -

124 to the Global Object: -

125 -

126 \snippet code/src_script_qjsengine.cpp 3 -

127 -

128 Adding custom properties to the scripting environment is one of the -

129 standard means of providing a scripting API that is specific to your -

130 application. Usually these custom properties are objects created by -

131 the newQObject() or newObject() functions. -

132 -

133 \section1 Script Exceptions -

134 -

135 evaluate() can throw a script exception (e.g. due to a syntax -

136 error). If it does, then evaluate() returns the value that was thrown -

137 (typically an \c{Error} object). Use \l QJSValue::isError() to check -

138 for exceptions. -

139 -

140 For detailed information about the error, use \l QJSValue::toString() to -

141 obtain an error message, and use \l QJSValue::property() to query the -

142 properties of the \c Error object. The following properties are available: -

143 -

144 \list -

145 \li \c name -

146 \li \c message -

147 \li \c fileName -

148 \li \c lineNumber -

149 \li \c stack -

150 \endlist -

151 -

152 \snippet code/src_script_qjsengine.cpp 4 -

153 -

154 \section1 Script Object Creation -

155 -

156 Use newObject() to create a JavaScript object; this is the -

157 C++ equivalent of the script statement \c{new Object()}. You can use -

158 the object-specific functionality in QJSValue to manipulate the -

159 script object (e.g. QJSValue::setProperty()). Similarly, use -

160 newArray() to create a JavaScript array object. -

161 -

162 \section1 QObject Integration -

163 -

164 Use newQObject() to wrap a QObject (or subclass) -

165 pointer. newQObject() returns a proxy script object; properties, -

166 children, and signals and slots of the QObject are available as -

167 properties of the proxy object. No binding code is needed because it -

168 is done dynamically using the Qt meta object system. -

169 -

170 \snippet code/src_script_qjsengine.cpp 5 -

171 -

172 Use newQMetaObject() to wrap a QMetaObject; this gives you a -

173 "script representation" of a QObject-based class. newQMetaObject() -

174 returns a proxy script object; enum values of the class are available -

175 as properties of the proxy object. -

176 -

177 Constructors exposed to the meta-object system (using Q_INVOKABLE) can be -

178 called from the script to create a new QObject instance with -

179 JavaScriptOwnership. For example, given the following class definition: -

180 -

181 \snippet code/src_script_qjsengine.cpp 7 -

182 -

183 The \c staticMetaObject for the class can be exposed to JavaScript like so: -

184 -

185 \snippet code/src_script_qjsengine.cpp 8 -

186 -

187 Instances of the class can then be created in JavaScript: -

188 -

189 \snippet code/src_script_qjsengine.cpp 9 -

190 -

191 \note Currently only classes using the Q_OBJECT macro are supported; it is -

192 not possible to expose the \c staticMetaObject of a Q_GADGET class to -

193 JavaScript. -

194 -

195 \section2 Dynamic QObject Properties -

196 -

197 Dynamic QObject properties are not supported. For example, the following code -

198 will not work: -

199 -

200 \snippet code/src_script_qjsengine.cpp 6 -

201 -

202 \section1 Extensions -

203 -

204 QJSEngine provides a compliant ECMAScript implementation. By default, -

205 familiar utilities like logging are not available, but they can can be -

206 installed via the \l installExtensions() function. -

207 -

208 \sa QJSValue, {Making Applications Scriptable}, -

209 {List of JavaScript Objects and Functions} -

210 -

211 */ -

212 -

213 /*! -

214 \enum QJSEngine::Extension -

215 -

216 This enum is used to specify extensions to be installed via -

217 \l installExtensions(). -

218 -

219 \value TranslationExtension Indicates that translation functions (\c qsTr(), -

220 for example) should be installed. -

221 -

222 \value ConsoleExtension Indicates that console functions (\c console.log(), -

223 for example) should be installed. -

224 -

225 \value GarbageCollectionExtension Indicates that garbage collection -

226 functions (\c gc(), for example) should be installed. -

227 -

228 \value AllExtensions Indicates that all extension should be installed. -

229 -

230 \b TranslationExtension -

231 -

232 The relation between script translation functions and C++ translation -

233 functions is described in the following table: -

234 -

235 \table -

236 \header \li Script Function \li Corresponding C++ Function -

237 \row \li qsTr() \li QObject::tr() -

238 \row \li QT_TR_NOOP() \li QT_TR_NOOP() -

239 \row \li qsTranslate() \li QCoreApplication::translate() -

240 \row \li QT_TRANSLATE_NOOP() \li QT_TRANSLATE_NOOP() -

241 \row \li qsTrId() \li qtTrId() -

242 \row \li QT_TRID_NOOP() \li QT_TRID_NOOP() -

243 \endtable -

244 -

245 This flag also adds an \c arg() function to the string prototype. -

246 -

247 For more information, see the \l {Internationalization with Qt} -

248 documentation. -

249 -

250 \b ConsoleExtension -

251 -

252 The \l {Console API}{console} object implements a subset of the -

253 \l {https://developer.mozilla.org/en-US/docs/Web/API/Console}{Console API}, -

254 which provides familiar logging functions, such as \c console.log(). -

255 -

256 The list of functions added is as follows: -

257 -

258 \list -

259 \li \c console.assert() -

260 \li \c console.debug() -

261 \li \c console.exception() -

262 \li \c console.info() -

263 \li \c console.log() (equivalent to \c console.debug()) -

264 \li \c console.error() -

265 \li \c console.time() -

266 \li \c console.timeEnd() -

267 \li \c console.trace() -

268 \li \c console.count() -

269 \li \c console.warn() -

270 \li \c {print()} (equivalent to \c console.debug()) -

271 \endlist -

272 -

273 For more information, see the \l {Console API} documentation. -

274 -

275 \b GarbageCollectionExtension -

276 -

277 The \c gc() function is equivalent to calling \l collectGarbage(). -

758 In the following example a C++ method in \e FileAccess.cpp throws an error -

759 in \e qmlFile.qml at the position where \c readFileAsText() is called: -

760 -

761 \code -

762 // qmlFile.qml -

763 function someFunction() { -

764 ... -

765 var text = FileAccess.readFileAsText("/path/to/file.txt"); -

766 } -

767 \endcode -

768 -

769 \code -

770 // FileAccess.cpp -

771 // Assuming that FileAccess is a QObject-derived class that has been -

772 // registered as a singleton type and provides an invokable method -

773 // readFileAsText() -

774 -

775 QJSValue FileAccess::readFileAsText(const QString & filePath) { -

776 QFile file(filePath); -

777 -

778 if (!file.open(QIODevice::ReadOnly)) { -

779 jsEngine->throwError(file.errorString()); -

780 return QString(); -

781 } -

782 -

783 ... -

784 return content; -

785 } -

786 \endcode -

787 -

788 It is also possible to catch the thrown error in JavaScript: -

789 \code -

790 // qmlFile.qml -

791 function someFunction() { -

792 ... -

793 var text; -

794 try { -

795 text = FileAccess.readFileAsText("/path/to/file.txt"); -

796 } catch (error) { -

797 console.warn("In " + error.fileName + ":" + "error.lineNumber" + -

798 ": " + error.message); -

799 } -

800 } -

801 \endcode -
