Graphics item position after drag

[aamer4yu]

What are you trying to do with drag and drop ?
If you simply want to move the item in the scene, you dont need to implement drag drop yourself... you just need to set the flags,,QGraphicsItem::setFlags , QGraphicsItem::ItemIsMovable


But if your requirement is implementing drag drop yourself, have a look at -
QGraphicsItem::dragEnterEvent
QGraphicsItem::dragLeaveEvent
QGraphicsItem::dragMoveEvent
QGraphicsItem::dropEvent
Hope this helps

Thanks for the info, it seems that this was the easy solution I was looking for

I dumbed the mousePressEvent etc. methods and simply set appropriate flag in my graphic item's ctor and... well, it kinda worked. I tested with a simple rectangle, it can be dragged but it leaves a trail in the scene (see attached capture). The trail disappears once the screen is refreshed, e.g. focusing other window and re-focusing my application. Dragging a pixmap didn't have this kind of effect... I'll keep investigating this.

...and a second after I clicked the Submit button, I realized where the problem is...

The black rectangle in previous post is drawn as a border for pixmap. However, my boundingRect function returned the rect for pixmap only and didn't calculate the border. That was also the reason why it worked well with pixmap... Once I fixed boundingRect return value it started to work slightly better

There are still some problems when there are several items shown, but I'll keep on digging.
