[Qt-interest] Fwd: mime data

[ami guru]

Hello forum,

I have some data types not defined in the QMimeData and the drag  & drop
operation occurs within a single application.

So i have decided to subclass QMimeData() and reimplement
hasFormat<qmimedata.html#hasFormat>(),
formats <qmimedata.html#formats>(), and
retrieveData<qmimedata.html#retrieveData>().



Cant fugure out the dfinitions inside the functions.

Lets start with formats()


QStringList H3DNodeData::formats() const
{
  return myFormat;
}


myFormat is a private variable that has been set as myFormat << "text/plain"
<< "icon";


need some hint about the rest of the functions.


Thanks
Sajjad

Thanks Bob,

I thought about that as well.

Then i pondered a bit ; Are QIcon and QImage  the same ?

I am dealing with QIcon that is not defined in the QMimeData

Sajjad

You probably want to use this function:

void QMimeData::setImageData ( const QVariant & image );
