Chained application in QT

[cglolo]

Hi,

on Symbian, i am currently using RAknAppServiceBase::ConnectChainedAppL().
This is used to "Allow a server app client to connect to a new server app, which
will be chained from the client app, giving it the appearance of being embedded within the client."

For instance, if i want to open the application responsible for opening/viewing zip files (call it A),
i can embed A within my own app, so i do not have to recode A myself.
From the viewer point of view, only one app is opened, you cannot see application A opened even
in the task list (on Nokia/Symbian devices).

1. Is there similar functionality in QT ?
2. I've read about QT Mobiilty Service framework. Is this the track to follow ?
3. Is it possible to initialize GUI app (QApplication) within the Qt service Method ?

From what I've read, you get a QObject from service framework as follows:
@
QServiceManager manager;
QObject *obj = manager.loadInterface("com.myservice.myobject");
if (obj)
QMetaObject::invokeMethod(obj, "myFunction", Q_ARG(QString, "arg1"));
@

and myFunction looks like this:
@
Q_INVOKABLE void myFunction(QString arg1)
{
... can QApplication be started here like standalone app ?
... so that this will appear as being embedded ?
}
@

A further requirement is that i do not want the call to GUI app to freeze the calling app...

I hope someone can help out there.

Cheers
