fd#44621 : OSX DND opens drawer Query

[Manik Malhotra]

It is now confirmed that this is the function that is called when an image
is dragged. Now the problem, I think there's something wrong with


 DropTargetDropEvent
<http://opengrok.libreoffice.org/s?defs=DropTargetDropEvent&project=core>
dtde <http://opengrok.libreoffice.org/s?defs=dtde&project=core>(static_cast
<http://opengrok.libreoffice.org/s?defs=static_cast&project=core><OWeakObject
<http://opengrok.libreoffice.org/s?defs=OWeakObject&project=core>*>(this
<http://opengrok.libreoffice.org/s?defs=this&project=core>),    345
<http://opengrok.libreoffice.org/xref/core/vcl/aqua/source/dtrans/DropTarget.cxx#345>
                              0,    346
<http://opengrok.libreoffice.org/xref/core/vcl/aqua/source/dtrans/DropTarget.cxx#346>
                              this

                              mSelectedDropAction
<http://opengrok.libreoffice.org/s?refs=mSelectedDropAction&project=core>,
   348  <http://opengrok.libreoffice.org/xref/core/vcl/aqua/source/dtrans/DropTarget.cxx#348>

                              posY

                              mDragSourceSupportedActions

                              xTransferable
<http://opengrok.libreoffice.org/s?refs=xTransferable&project=core>);


The 3rd argument is the current drop context.


I've tried using static_cast
<http://opengrok.libreoffice.org/s?defs=static_cast&project=core><XDropTargetDragContext
<http://opengrok.libreoffice.org/s?defs=XDropTargetDragContext&project=core>*>(
this <http://opengrok.libreoffice.org/s?defs=this&project=core>)

Which gives an error and next step would be to use static_cast
<http://opengrok.libreoffice.org/s?defs=static_cast&project=core><XDropTargetDropContext
<http://opengrok.libreoffice.org/s?defs=XDropTargetDragContext&project=core>*>(
this <http://opengrok.libreoffice.org/s?defs=this&project=core>)

Anyway,

Class DropTarget has a private field

    149  <http://opengrok.libreoffice.org/xref/core/vcl/aqua/source/dtrans/DropTarget.hxx#149>
 com <http://opengrok.libreoffice.org/s?defs=com&project=core>::sun
<http://opengrok.libreoffice.org/s?defs=sun&project=core>::star
<http://opengrok.libreoffice.org/s?defs=star&project=core>::uno
<http://opengrok.libreoffice.org/s?defs=uno&project=core>::Reference
<http://opengrok.libreoffice.org/s?defs=Reference&project=core>< com
<http://opengrok.libreoffice.org/s?defs=com&project=core>::sun
<http://opengrok.libreoffice.org/s?defs=sun&project=core>::star
<http://opengrok.libreoffice.org/s?defs=star&project=core>::datatransfer
<http://opengrok.libreoffice.org/s?defs=datatransfer&project=core>::dnd
<http://opengrok.libreoffice.org/s?defs=dnd&project=core>::XDropTargetDropContext
<http://opengrok.libreoffice.org/s?defs=XDropTargetDropContext&project=core>
> mXCurrentDropContext
<http://opengrok.libreoffice.org/s?refs=mXCurrentDropContext&project=core>;

Shouldn't this be passed to the constructor.

I've tried it and what happens is that drag drop operation doesn't
work anymore (Draw isn't opened either).


It is also really annoying to build everything every time since
building vcl doesn't work, is there any other way than building
dev-install ?
