well , I also think that the document about Drag and Drop is not clear enough.. Reading from example code is more easy to understand.
Anyway , the solution to your problem: You should call drag.accept() within the onEntered slot. Then it will enable the onDropped slot to be executed. http://qt-project.org/doc/qt-5/qml-qtquick-dragevent.html#accept-method On 15 May 2014 04:04, Kevin Funk <kf...@kde.org> wrote: > Hey, > > I'm trying to get my head around the QML Drag and Drop API and keep finding > oddities.
