use the plugin and QT script at the same time

[SamT]

Can I use the plugin function and the QT script at the same program? That means to build a plugin DLL and load by plugin loader then I can use write a easy script to drive that plugin.

I try to implement this idea into my program. The plugin load successfully but I can't drive by the script. Does anybody uses this idea in your program? Any example for me to study?


My plugin interface

class TaInterface
{
public:
    virtual ~TaInterface() {}
    virtual QString pluginName() = 0;
 
public slots:
    virtual bool initialize(const QStringList &arguments, QString *errorString) = 0;
    virtual QString function() = 0;

class TaInterface
{
public:
    virtual ~TaInterface() {}
    virtual QString pluginName() = 0;

public slots:
    virtual bool initialize(const QStringList &arguments, QString *errorString) = 0;
    virtual QString function() = 0;

Load plugin and set to script engine

void MainWindow::loadPlugins()
{
    engine = new QScriptEngine(this);
 
    pluginsDir = QDir(qApp->applicationDirPath());
 
    if (pluginsDir.dirName().toLower() == "debug" || pluginsDir.dirName().toLower() == "release")
        pluginsDir.cdUp();
 
    pluginsDir.cd("plugins");
 
    foreach (QString fileName, pluginsDir.entryList(QDir::Files))
    {
        QPluginLoader loader(pluginsDir.absoluteFilePath(fileName));
        QObject *plugin = loader.instance();
        if (plugin)
        {
            pluginFileNames += fileName;
            Interface *ta = qobject_cast<Interface *>(plugin);
 
            QScriptValue TaToScript = engine->newQObject(plugin);
            engine->globalObject().setProperty(ta->pluginName(), TaToScript);
 
        }
 
    }
}

void MainWindow::loadPlugins()
{
    engine = new QScriptEngine(this);

    pluginsDir = QDir(qApp->applicationDirPath());

    if (pluginsDir.dirName().toLower() == "debug" || pluginsDir.dirName().toLower() == "release")
        pluginsDir.cdUp();

    pluginsDir.cd("plugins");

    foreach (QString fileName, pluginsDir.entryList(QDir::Files))
    {
        QPluginLoader loader(pluginsDir.absoluteFilePath(fileName));
        QObject *plugin = loader.instance();
        if (plugin)
        {
            pluginFileNames += fileName;
            Interface *ta = qobject_cast<Interface *>(plugin);

            QScriptValue TaToScript = engine->newQObject(plugin);
            engine->globalObject().setProperty(ta->pluginName(), TaToScript);

        }

    }
}
