Hello,
I've found this code snippet in PyQt eample for drag and drop of images. Can
anyone plz help me out in understanding this code snippet. I am new to this.
child = self.childAt(event.pos())
if not child:
return
pixmap = QtGui.QPixmap(child.pixmap())
itemData = QtCore.QByteArray()
dataStream = QtCore.QDataStream(itemData,
QtCore.QIODevice.WriteOnly)
dataStream << pixmap << QtCore.QPoint(event.pos() - child.pos())
mimeData = QtCore.QMimeData()
mimeData.setData('application/x-dnditemdata', itemData)
drag = QtGui.QDrag(self)
drag.setMimeData(mimeData)
drag.setPixmap(pixmap)
drag.setHotSpot(event.pos() - child.pos())
tempPixmap = QtGui.QPixmap(pixmap)
painter = QtGui.QPainter()
painter.begin(tempPixmap)
painter.fillRect(pixmap.rect(), QtGui.QColor(127, 127, 127, 127))
painter.end()
Also, what does 'x-dnditemdata' mean in the line:
event.mimeData().hasFormat('application/x-dnditemdata')
I'll be really grateful if someone can help me out with this.
