The QJSValue class provides functions for converting the result to various C++ types (e.g. QJSValue::toString() and QJSValue::toNumber()). The following code snippet shows how a The extensions for JavaScript are QtScript [7] and QJSEngine [8], both provided by Qt framework. The extensions for Lua in Qt are QtLua by Savannah projects. [9] and Lqt [10]. The extensions for Python in Qt are PyQt by Riverbank Computing [11], Pyside by Nokia [12],. Pyotherside [13] and PythonQt [14]. The extensions for. 5 июл 2017 In the same file, we define the static function singletonProvider , which will create a singleton instance. #ifndef SINGLETONCLASS_H; #define SINGLETONCLASS_H; #include ; #include ; #include ; class SingletonClass : public QObject; {; Q_OBJECT; public: explicit QJSEngine engine; qDebug() << "the magic number is:" << engine.evaluate("1 + 2").toNumber();. The return value will be the result of the evaluation (represented as a QJSValue object); this can be converted to standard C++ and Qt types. Custom properties can be made available to scripts by registering them with the script 10 May 2008 If it's not, you should probably look at the Qt tutorials before going any further. Before we can use this class in any sensible manner, we need to do two things: Create a QScriptValue object that represents the "this" pointer. We do this so that we can call a script function, and pass it the C++ class object as In contrast to QScriptEngine , where you can add custom classes if they inherit from QObject by using the Q_SCRIPT_DECLARE_QMETAOBJECT macro, the QJSEngine does not directly provide this functionality. You can still use the Qt Meta-object system to provide interfaces for Javascript, but you have to 31 Mar 2016 Interesting repo you have here. I'm working on something similar. Trying to unite some Node.js and Qt code bases. We have a large legacy code base that uses Qt Script . Now that it's deprecated, we're looking for a path forward. This repo looks like a great start. I'm currently exploring what's needed to add 12 Aug 2012 This blog is an informative resource for coders who want to learn more about the BlackBerry 10 Cascades coding environment.
