how to get both qgraphicsscene and qgraphicsitem to both accept drops

[kghose]

Hi Gang,

I have some items on a qgraphicsscene and I want to be able to drag and drop an item onto another or onto a blank part of the scene. Depending on whether the drop occurs over another item or over a blank part of the scene two different things happen.

The way I'm doing this currently is backwards (I think) but is the only way I can get it to work.

MyGraphicsScene::dropEvent(....) {
  QGraphicsScene::dropEvent(...)
  if(!event->isAccepted()) {
     event->accept()
     return
 }
 else
    do what needs to be done if the drop is on an empty space
}

MyGraphicsScene::dropEvent(....) {
  QGraphicsScene::dropEvent(...)
  if(!event->isAccepted()) {
     event->accept()
     return
 }
 else
    do what needs to be done if the drop is on an empty space
}

MyGraphicsItem::dropEvent(...) {
   do things
   event->ignore();
	//This is why we did this. The event comes to us 'accept'ed. If it
	//passes into this function we 'ignore' it as a signal to the parent
	//(qgraphicsscene) that it should not operate on it. Otherwise
	//the event comes with the accept flag and qgraphicsscene acts in it
	//This is so ass-backwards. There should be
	//a better way of doing this
 
}

MyGraphicsItem::dropEvent(...) {
   do things
   event->ignore();
	//This is why we did this. The event comes to us 'accept'ed. If it
	//passes into this function we 'ignore' it as a signal to the parent
	//(qgraphicsscene) that it should not operate on it. Otherwise
	//the event comes with the accept flag and qgraphicsscene acts in it
