如何创建一个将Nc列表转换为Qtableview的类？
class NcTableModel(QtCore.QAbstractTableModel):
"""
Class to populate Nc table view from a list of Nc instance
"""
...
view = QtWidgets.QTableView()
model=NcTableModel(listNc)
view.setModel(model)
view.update()
class Nc:
cst: str
pNbr : str
desc : str
class NcTableModel(QtCore.QAbstractTableModel):

QtCore.QAbstractTableModel.__init__(self,parent)
self._data = data
def rowCount(self,parent):
return len(self._data)

return len(Nc.__dataclass_fields__.keys())
def data(self,index,role=QtCore.Qt.DisplayRole):
if not index.isValid():
return QVariant()
elif role == QtCore.Qt.EditRole:
print( "edit mode" )
return None

return None
return astuple(self._data[index.row()])[index.column()]
