QGraphicsItem and dragEvents

Goffer

Hey Community,

I can't get my drag events to work on QGraphicsItem. Even with the setAcceptDrops(True), is there something else to do to enable them ? They work by default on regular widgets...
Since QGraphicsItems are movable, I understand that it might be a little bit different but can't figure this out.

here is a sample code :

from PySide import QtGui, QtCore

class GraphicItem(QtGui.QGraphicsItem):

    def __init__(self, parent=None):
        super(GraphicItem, self).__init__(parent)

        self.setAcceptDrops(True)

    def boundingRect(self):
        rect = QtCore.QRect(0,0,400,400)
        return rect

    def shape(self):
        path = QtGui.QPainterPath()
        path.addRect(self.boundingRect())
        return path

    def paint(self, painter, option, widget):
        painter.setBrush(QtGui.QColor(255,0,0,255))
        painter.drawRect(self.boundingRect())

    def dragEnterEvent(self, event):
        print 'drag enter'
        super(GraphicItem, self).dragEnterEvent(event)

    def dragMoveEvent(self, event):
        print 'drag move'
        super(GraphicItem, self).dragMoveEvent(event)


s = QtGui.QGraphicsScene()
v = QtGui.QGraphicsView(s)
v.show()

ti = GraphicItem(parent=None)
s.addItem(ti)

Thanks

Hi,

Do you want to move your items around ?

Goffer

Nope, It is just a static item that it driven by a parent.
For now I have to do it with mouse press/move/release events + a condition ...
It works but i feel like the drag events are designed for that.

Or, am I wrong ?

Then what exactly do you want to achieve using drag and drop ?
