你不需要使用setData(...)
. 相反,您需要以这样的方式进行子类化,QAbstractTableModel
即它的方法rowCount()
、、和可能返回您希望显示的数据。下面是一个基于 PyQt5 的示例:columnCount()
data(index)
headerData(section, horizontalOrVertical)
from PyQt5.QtWidgets import *
from PyQt5.QtCore import *
headers = ["Scientist name", "Birthdate", "Contribution"]
rows = [("Newton", "1643-01-04", "Classical mechanics"),
("Einstein", "1879-03-14", "Relativity"),
("Darwin", "1809-02-12", "Evolution")]
class TableModel(QAbstractTableModel):
def rowCount(self, parent):
# How many rows are there?
return len(rows)
def columnCount(self, parent):
# How many columns?
return len(headers)
def data(self, index, role):
if role != Qt.DisplayRole:
return QVariant()
# What's the value of the cell at the given index?
return rows[index.row()][index.column()]
def headerData(self, section, orientation, role):
if role != Qt.DisplayRole or orientation != Qt.Horizontal:
return QVariant()
# What's the header for the given column?
return headers[section]
app = QApplication([])
model = TableModel()
view = QTableView()
view.setModel(model)
view.show()
app.exec_()
