Actually it is possible:
XAP_App * pApp = XAP_App::getApp();
XAP_Frame * pFrame = pApp->getLastFocussedFrame();
XAP_UnixFrame * pUFrame = static_cast<XAP_UnixFrame *>(pFrame);
This will work at any point in the code.

The above code will give you the a XAP_App ppointer too :-)

Yes see above. With this code you can get anything you want in Abi from
anywhere in abi, including a plugin :-)

Joaquin if you use this code will it help in the Perl bindings?
