self.tableView.installEventFilters(self)
现在，添加事件过滤器：
def eventFilter(self, source, event): if (event.type() == QtCore.QEvent.KeyPress and event.matches(QtGui.QKeySequence.Copy)): self.copySelection() return True return super(Window, self).eventFilter(source, event)
复制功能：
def copySelection(self): selection = self.tableView.selectedIndexes() if selection: rows = sorted(index.row() for index in selection) columns = sorted(index.column() for index in selection) rowcount = rows[-1] - rows[0] + 1 colcount = columns[-1] - columns[0] + 1 table = [[''] * colcount for _ in range(rowcount)] for index in selection: row = index.row() - rows[0] column = index.column() - columns[0] table[row][column] = index.data() stream = io.StringIO() csv.writer(stream).writerows(table) QtGui.qApp.clipboard().setText(stream.getvalue())
