[PySide] QListView with delegate: support drag outside of QApplication

[Frank Rueter | OHUfx]

For posterity, this is the solution:

|import sys from PySide import QtGui, QtCore class 
MyModel(QtGui.QStandardItemModel): def __init__(self, w, parent=None): 
super(MyModel, self).__init__(parent) def mimeData(self, indexes): 
mimeData = super(MyModel, self).mimeData(indexes) 
mimeData.setText('test') return mimeData class MyList(QtGui.QListView): 
def __init__(self, parent=None): super(MyList, self).__init__(parent) 
self.setDragEnabled(True) self.setAcceptDrops(True) if __name__ == 
'__main__': app = QtGui.QApplication(sys.argv) list1 = MyList() list2 = 
MyList() model1 = MyModel(list1) model2 = MyModel(list1) 
model2.setItemPrototype(QtGui.QStandardItem()) foods = [ 'Cookie dough', 
'Hummus', 'Spaghetti', 'Dal makhani', 'Chocolate whipped cream' ] for 
food in foods: item = QtGui.QStandardItem(food) model1.appendRow(item) 
list1.setModel(model1) list2.setModel(model2) w = QtGui.QSplitter() 
w.addWidget(list1) w.addWidget(list2) w.show() w.raise_() app.exec_() |
