在pyside中为qtreeview添加多列儿童

如何添加如下图所示的儿童节点。我知道如何添加一行和一个孩子。但是，当我试图添加一个在第二列有一个复选框的子节点时，我遇到了困难。在pyside中为qtreeview添加多列儿童

    def __init__(self, name='', team=''): 
     self.name = name 
     self.team = team

    def __init__(self, name='', team=''): 
     self.name = name 
     self.team = team 
     self.op_quarterback = False 
     self.op_center = False 
     self.op_coach = False 

class Example(QtGui.QMainWindow): 
    def __init__(self, parent=None): 
     super(Example, self).__init__(parent) 
     self.resize(500, 300) 
     self.setWindowTitle('Test') 

     # variables 
     self.assets = [ 
      Soccer(name='Doug', team='Nailers'), 
      Soccer(name='Leslie', team='Sonics'), 
      Football(name='Kevin', team='Patriots'), 
      Football(name='Matt', team='Cowboys'), 
     ] 

     # create widgets 
     lb_simulators = QtGui.QLabel('Simulators') 
     lb_simulators.setProperty('class', 'section')

     main_widget = QtGui.QWidget() 
     main_widget.setLayout(grid) 
     self.setCentralWidget(main_widget) 

     self.create_model() 

    def create_model(self): 
     model = self.ui_items.model() 
     model.clear() 
     headers = ['Name', ''] # 'Sim', 'Continue', 'Wavelet/Resim', 'Post'] 
     model.setHorizontalHeaderLabels(headers) 
     self.ui_items.sortByColumn(0, QtCore.Qt.AscendingOrder) 

     for x in self.assets: 
      model.insertRow(0) 

      # Append object 
      model.setData(model.index(0, 0), x, role=QtCore.Qt.UserRole) 
      model.setData(model.index(0, 0), x.name) 
      model.setData(model.index(0, 1), x.team) 

      # if isinstance(x, Football): 
      #  item = model.itemFromIndex(model.index(0,0)) 


def main(): 
    app = QtGui.QApplication(sys.argv) 
    ex = Example() 
    ex.show() 
    sys.exit(app.exec_()) 

if __name__ == '__main__': 
    main()

的setData方法用于设置指定data role的值。使项目可检查的角色是Qt.CheckStateRole，值由check-state enum给出。

所以在您的示例中的第二列可以进行辨认的是这样的：

model.setData(model.index(0, 1), x.team) 
model.setData(model.index(0, 1), QtCore.Qt.Unchecked, QtCore.Qt.CheckStateRole)

不过，如果您使用的是QStandardItemModel，它提供了一个更可读的语法，所以你的循环来填充可以在树状重写如下：

for x in self.assets: 
    column1 = QtGui.QStandardItem(x.name) 
    column1.setData(x, QtCore.Qt.UserRole) 
    column2 = QtGui.QStandardItem(x.team) 
    column2.setCheckable(True) 
    model.appendRow([column1, column2])
