class Button(QtGui.QPushButton):
def mouseMoveEvent(self, e):
if e.buttons() != QtCore.Qt.RightButton:
return
mimeData = QtCore.QMimeData()
mimeData.setText('%d,%d' % (e.x(), e.y()))
pixmap = QtGui.QPixmap.grabWidget(self)
painter = QtGui.QPainter(pixmap)
painter.setCompositionMode(painter.CompositionMode_DestinationIn)
painter.fillRect(pixmap.rect(), QtGui.QColor(0, 0, 0, 127))
painter.end()
drag = QtGui.QDrag(self)
drag.setMimeData(mimeData)
drag.setPixmap(pixmap)
drag.setHotSpot(e.pos())
if drag.exec_(QtCore.Qt.CopyAction & QtCore.Qt.MoveAction) ==
QtCore.Qt.MoveAction:
print 'moved'
else:
print 'copied'
def mousePressEvent(self, e):
QtGui.QPushButton.mousePressEvent(self, e)
if e.button() == QtCore.Qt.LeftButton:
print 'press'

button.move(100, 65)
button1.move(200, 65)
self.buttons = [button]
self.setWindowTitle('Copy or Move')
self.setGeometry(300, 300, 280, 150)
def dragEnterEvent(self, e):
e.accept()
def dropEvent(self, e):
mime = e.mimeData().text()
x, y = map(int, mime.split(','))
if e.keyboardModifiers() & QtCore.Qt.ShiftModifier:
button = Button('Button', self)
button1 = Button('Button1', self)
button.move(e.pos()-QtCore.QPoint(x, y))
button1.move(e.pos()-QtCore.QPoint(x, y))
button.show()
button1.show()
self.buttons.append(button)
self.buttons.append(button1)
e.setDropAction(QtCore.Qt.CopyAction)
else:
e.source().move(e.pos()-QtCore.QPoint(x, y))
e.setDropAction(QtCore.Qt.MoveAction)
e.accept()
if __name__ == '__main__':
app = QtGui.QApplication(sys.argv)
ex = Example()
ex.show()
