Expected constructor, destructor, or type conversion before ‘(’ token

i get this error at the line where i to let Qt to know that the ActionPlugin class is a plugin

@#include "actionplugin.h"

QAction* ActionInterface::newAction() {

QAction *pluginAction = new QAction(NULL);

return pluginAction;

}

Q_EXPORT_PLUGIN2(actionplugin,ActionPlugin); // here is the problem@

That can be ?

You are obviously trying to export a class named ActionPlugin, whereas at least newAction() is a member of a class called ActionInterface. There is no such class called ActionPlugin, at least not in the piece of code you've posted, neither did you include <QtPlugin>.

header file looks like (in previsious code snippet i show just impelmentation of method from an interface)

@#ifndef ACTIONPLUGIN_H
#define ACTIONPLUGIN_H

#include <QObject>
#include <QAction>
#include "actioninterface.h"

class ActionPlugin : public QObject,ActionInterface {

Q_OBJECT
Q_INTERFACES (ActionInterface)

public :
QAction* newAction() const;

~ActionPlugin () {}
ActionPlugin () {}

};

#endif // ACTIONPLUGIN_H@

If ActionPlugin should implement the interface method newAction() it has to read ActionPlugin::newAction(), not ActionInterface::newAction().

you should inherit ActionInterface public, otherwise it's private...

done , but do not solve problem ... may be Compile Output helps

Is that a literal paste of your code? The trailing ';' is an error.
