QTPlugin Constructor arguments

[Suths]

Hi all, maybe its just been a long day but i can't seem to spot my fault here .

I'm trying to create a plugin where the constructor interface has some required arguments.

for example take this

Interface:
@
QT_BEGIN_NAMESPACE
class QObject;
QT_END_NAMESPACE

namespace INTERFACE
{
     class testInterfacePlugin: public QObject
     {
     public:

         testInterfacePlugin(FOO x)

         virtual ~testInterfacePlugin(){}

     };
}

QT_BEGIN_NAMESPACE

#define testInterfacePlugin_iid "testInterfacePlugin"

Q_DECLARE_INTERFACE(INTERFACE::testInterfacePlugin, testInterfacePlugin_iid)
@

Plugin:
@
namespace INTERFACE
{
class Test_plugin: public INTERFACE:testInterfacePlugin
{

        Q_OBJECT
        Q_PLUGIN_METADATA(IID "testInterfacePlugin_iid " FILE "test_plugin.json")
        Q_INTERFACES(INTERFACE::testInterfacePlugin)

    public:

        Test_plugin(FOO x);


    };
}

@

where the JSON file is empty, however when I go to compile this I keep getting a "no matching call to a testInterfacePlugin(FOO)" error message, almost like it can't tell that the interface has that constructor. Has anyone come across this before and do they know how to resolve it.

U did not implement constructor for interface. Also don't inherit interface from who jet.

Thanks for the response Dheerendra but i'm not sure i follow your statement, the interface has a constructor testInterfacePlugin(FOO x), and i'm not to sure what you meant by "Also don't inherit interface from who jet" would you mind elaborating.
Thanks

You need implement constructor in interface definition. Don't inherit interface from qobject. Sorry due to some auto completion qobject has become jet. .
