PyQt5学习笔记6_QTableView中嵌入按钮

开发环境：PyQt 5.5.1 Python 3.4.4
参考Button Delegate For QTableViews给出的例程，实现在一个单元格中嵌入多个按钮，代码如下：

import sysfrom PyQt5.QtCore import (Qt, QAbstractTableModel, QModelIndex, QVariant)from PyQt5.QtWidgets import (QApplication, QHBoxLayout, QItemDelegate, QPushButton, QTableView, QWidget)class MyModel(QAbstractTableModel):    def __init__(self, parent=None):        super(MyModel, self).__init__(parent)    def rowCount(self, QModelIndex):        return 4    def columnCount(self, QModelIndex):        return 3    def data(self, index, role):        row = index.row()        col = index.column()        if role == Qt.DisplayRole:            return 'Row %d, Column %d' % (row + 1, col + 1)        return QVariant()class MyButtonDelegate(QItemDelegate):    def __init__(self, parent=None):        super(MyButtonDelegate, self).__init__(parent)    def paint(self, painter, option, index):        if not self.parent().indexWidget(index):            button_read = QPushButton(                self.tr('读'),                self.parent(),                clicked=self.parent().cellButtonClicked            )            button_write = QPushButton(                self.tr('写'),                self.parent(),                clicked=self.parent().cellButtonClicked            )            button_read.index = [index.row(), index.column()]            button_write.index = [index.row(), index.column()]            h_box_layout = QHBoxLayout()            h_box_layout.addWidget(button_read)            h_box_layout.addWidget(button_write)            h_box_layout.setContentsMargins(0, 0, 0, 0)            h_box_layout.setAlignment(Qt.AlignCenter)            widget = QWidget()            widget.setLayout(h_box_layout)            self.parent().setIndexWidget(                index,                widget            )class MyTableView(QTableView):    def __init__(self, parent=None):        super(MyTableView, self).__init__(parent)        self.setItemDelegateForColumn(0, MyButtonDelegate(self))    def cellButtonClicked(self):        print("Cell Button Clicked", self.sender().index)if __name__ == '__main__':    a = QApplication(sys.argv)    tableView = MyTableView()    myModel = MyModel()    tableView.setModel(myModel)    tableView.show()    a.exec_()

效果如下：
