[提问]QtScript [复制链接]

大家帮我看看，为什么我的脚本不能执行
#include <QtGui>
#include <QtUiTools>
#include <QtScript>
#include <QMessageBox>
class Testss {
public:    
    Testss(){};
    ~Testss(){};
    void start()
        {
            Q_INIT_RESOURCE(ddd);
            QScriptEngine engine;

            QFile scriptFile(":/teste.js");
            if(!scriptFile.open(QIODevice::ReadOnly)){
                 QMessageBox::warning(NULL,QObject::tr("open"),QObject::tr("open failed"));
            }
            engine.evaluate(scriptFile.readAll());
            scriptFile.close();

            QUiLoader loader;
            QFile uiFile(":/teste.ui");
            if(!uiFile.open(QIODevice::ReadOnly)){
                QMessageBox::warning(0,QObject::tr("open"),QObject::tr("open failed"));
            }
            QWidget *ui = loader.load(&uiFile);
            uiFile.close();

            QScriptValue func = engine.evaluate("nextClass");
            QScriptValue scriptUi = engine.newQObject(ui);
            QScriptValue table = func.construct(QScriptValueList() << scriptUi);
            if(engine.hasUncaughtException()) {
                QScriptValue value = engine.uncaughtException();
                QString lineNumber = QString("\nLine Number:%1\n").arg(engine.uncaughtExceptionLineNumber());
                QStringList btList = engine.uncaughtExceptionBacktrace();
                QString trace;
                for(short i=0; i<btList.size(); ++i)
                    trace += btList.at(i);
                QMessageBox::information(NULL, QObject::tr("Exception"), value.toString() + lineNumber + trace );
            }
            
            ui->show();
    }
    
};
int main(int argc,char **argv)
{    
    
    QApplication app(argc, argv);
    Testss w;
    w.start();
    return app.exec();
}


下面是js

function nextClass(ui)
{
    this.ui = ui;
    ui.pushButton.clicked.connect(this,this.showtext);
    ui.pushButton1.clicked.connect(this,ui.close);    
    
}
nextClass.prototype.showtext = function()
{        
    this.ui.textEdit.setText(this.ui.lineEdit.text);
}

下面是.ui

为什么我把类里Start函数里的代码放到main函数中脚本就能执行，而在放到函数中就不能呢

希望大家能够帮助呀，很着急，先谢谢了

把
Q_INIT_RESOURCE(ddd);
移到
QApplcation
那行后面看看

使过了，还是不行呀

那个问题解决了，只要把QScriptEngine engine;放到主函数中就行了。但是现在还有个问题，就是假设我有这几个文件，
main.cpp，test.cpp，test.h和一个.ui 文件，如果我在test.cpp 的构造函数中使用了setupUi（this），然后在动态加载时js和ui,操作控件只能一个能用。

问题解决了

我也遇到这个问题，请问怎么解决的？麻烦指点一二
